Why does new boiler installation cost vary so much?

There are considerable expenses involved for each type of boiler and a new boiler installation cost can increase greatly with things like moving a boiler or changing boiler type.

At Boiler Central, we install thousands of boilers every year across the country, so we know what we are talking about. Therefore there are a few considerations to take into account if your boiler is working:

1. Is it over 10 years old?
2. Are your gas bills abnormally high?
3. Is your boiler regularly breaking down or working intermittently?
4. Is it overheating or making a funny noise?
5. Is it out of warranty?
6. Are you thinking of selling your house?

These are just some of the reasons that it may be worth buying a new boiler, and while costs are continuing to rise, it may be better to consider doing now rather than in the future.

New gas boiler costs continue to rise slowly

As inflation continues to take its toll, prices for boilers may fluctuate and homeowners may become less inclined to purchase, as they grapple with rising boiler installation costs.

However, the market for gas boilers is competitive, offering a wide range of options and the potential for great deals on the latest models. In the UK, the cost of installing a gas boiler has not risen significantly in recent years, making it a more affordable option.

Rising gas prices also mean that replacing your old boiler can actually save you money in the long term, by lowering your gas bills and preventing excess boiler repair costs.

It is worth noting that prices and availability may change during the winter months as demand increases and potential stock shortages occur. To save cost, it is recommended to purchase and install a boiler during the summer months when demand is lower.

What about central heating and radiators?

New boiler costs do not include new central heating systems or radiators, these would be extra costs on top. If you already have modern radiators there is no need to replace them, but if you don’t then you should consider that central heating installation costs are much higher due to more parts and labour costs.

Expect costs to be in the region of £3,500 to £6,000 depending on the size of your home and the types of radiators that you choose.

How much does a new combi boiler cost?

Gas combi boilers are the most popular type of boiler in the UK and cost £500 + VAT up to £3,000 + VAT. We install thousands nationwide every year, so we can negotiate better prices and pass the savings down to our customers

At Boiler Central, we cover everything from gas combi boiler costs, gas system boilers, regular boilers, and hydrogen-ready boilers (to 20% blend), as well as any additional extras your home may need or to look out for when looking at boilers.

We leave no stone unturned in this ultimate new combi boiler installations price guide to ensure that we keep costs down for homeowners and landlords alike and that Boiler Central is the go-to gas boiler installation company for all your needs.

Is it worth getting a new combi boiler now?

Deciding on whether or not it is worth getting a new modern combi boiler depends on how old your boiler is really, as older boilers become much less energy efficient over time, costing you more in gas and electricity bills.

An older combi boiler would be over ten years old, but luckily this guide will help you weigh that up in terms of price and if you think the outlay is worth it in the long term.

New combi boiler cost fitted

The cost of installing a boiler can vary, therefore new combi boilers typically cost between £1,500 and £2,750, depending on the brand and model, as well as the labour cost of the heating engineer.

New system boilers typically cost between £1,600 and £2,900, while regular, heat-only, or conventional boilers typically cost between £1,800 and £3,200, depending on the specific boiler chosen and the time it takes to install.

At Boiler Central, we are one of the most affordable new boiler companies in the UK and we’re so confident in our prices that we will match any quotes. Keep in mind that the cost of boiler installation can also be affected by factors such as the complexity of the installation: for example, if you want us to move the boiler to another room, or your property is in a high-rise building.

It’s also recommended to make sure your new boiler is hydrogen ready to 20% blend. All the prices above include new boilers with installation by a Gas Safe Installer.

More often than not, the actual installation process is the largest cost of a the whole boiler replacement

Combi boiler cost and prices fitted

Prices range from £1,500 – £3,000

A new combi boiler costs between £1,500 and £3,000. This is the “on the wall price” you can expect to pay, and includes the boiler itself, full combi boiler installation by a Gas Safe engineer, warranty registration and VAT.

Every combi boiler installation is different, so the amount of work required by a Gas Safe engineer can vary substantially from job to job.

For this reason, labour costs will vary depending on whether you are replacing an existing combi boiler like-for-like, or updating from a system, regular (heat-only) or converting a back boiler to a combi boiler.

Unless you have multiple bathrooms, converting from a system boiler or regular boiler to a combi will incur a bigger initial outlay, but can save you money in the long-run by helping you cut down on energy usage which is on everyone’s mind at the moment.

At Boiler Central, we will struggle to be beaten on price and there are no additional costs so ensure that you answer all our questions correctly so you can be sure that you are getting the best combi boiler deal we can offer right now to lower your heating bills.

Combi boiler installation cost

So how much does a combi boiler installation cost? Luckily, replacing a combi boiler with another combi, is a straightforward job. However, these factors which may affect your new combi boiler price:

• Amount of new pipework that needs adding

• What floor the boiler is on (flats may require scaffolding)
• Location in the UK – London boiler installations seem to be higher prices
• The company you choose to install your new boiler
• Warranty length

As you can see above there are many things that can affect a combi boiler installation cost overall.

There are budget boilers out there with budget prices, as well as premium boilers which will set you back several thousand more.

Latest new combi boiler installation costs

Combi boiler installations are quick, easy, and often the cheapest replacement option for energy efficient heating.

The cost of combi boiler installation is generally lower if you are just replacing one combi with another, therefore you can expect new combi boiler prices will be higher if you are changing from another type of boiler system.

Whilst boilers are constantly changing and improving, including the rising cost of materials, what you pay is directly affected by this. The table below shows the latest combi boiler prices including fitting from the top boiler brands right now such as Worcester Bosch, Viessmann and Ideal.

Combi Boiler Model	Boiler Installation Cost
Worcester Bosch 4000 30kW Combi boiler	£2,090
Worcester Bosch 4000 25kW Combi boiler	£2,010

How much are hydrogen ready combi boilers?

Hydrogen-ready combi boilers are able to use a 20% blend of hydrogen to natural gas to keep your home warm while emitting lower carbon emissions in the UK and worldwide.

The best thing is that most new combi boilers are now hydrogen blend-ready, with top manufacturers such as Worcester Bosch, Viessmann, Ideal, Baxi and Vaillant all producing H₂-ready boilers.

System boiler to combi conversion cost

When it comes to new boiler costs with installation, system boilers are a great option for larger homes, and many homes in the ’60s onwards will have a system boiler installed.

A system boiler has 2 parts to it:

1. An actual boiler
2. A separate water tank to store hot water

The boiler (usually found in the kitchen) heats the water, which is then sent to the hot water storage tank that is usually found in an airing cupboard.

Once the demand for hot water is required, the hot water comes out of the hot water cylinder.

This is when the boiler will fire up and start to heat water and send it to the hot water tank to keep it at a certain fill level.

System boilers are still the right choice for homes with a higher demand for hot water, and are typically installed in homes with 3+ bathrooms as a minimum.

So, you are probably wondering what work is required and how much new boiler installation with a hot water tank, thinking that this sounds more expensive than the first combi boiler option. Well, you are right, see below.

Converting a boiler — Short term pain, long term gain

How much does a system boiler cost?

System boiler prices range from £1,600 to £2,900

This option is slightly more costly than a combi swap, coming in at around £1,600 for a basic boiler with a low five-year warranty for example.

If you would like a mid to high-end system boiler replacement, then the new gas boiler cost would be around £1,900 to £2,900, depending on the make and model.

The new system boiler replacement costs are made up of the system boiler itself, fitting and labour. The price of a system boiler includes only the boiler — not the tank.

System boiler conversion to a combi boiler prices

Prices range from £2,300 – £3,000

As you can see, the main downside to installing a system boiler is the cost of boiler replacement. However, many customers who have a home with 1–4 bedrooms can easily have a combi boiler power their heating and hot water, so why would you replace an old system boiler?

What 92% of Boiler Central’s customers are doing is replacing their old system boiler and hot water tank with an all-in-one combi boiler.

Not only will the combi boiler do the same job, if not better, but it will also free up space where the old hot water tank used to be. Everyone loves extra storage space, right?

Converting a system boiler setup to a combi boiler is a bigger job: prices are higher, and it will usually take the installation team two days to finish the job. Full removal and disposal of your hot water tank is included in the cost.

As we all know, labour is one of the most expensive parts of most service work, so prices will increase to reflect the additional work required.

As a guide, a system-to-combi boiler conversion is priced around £2,300 for a basic to a mid-range boiler, and then for a higher-end boiler, the price would be closer to £3,000.

Remember though, once it’s done, it’s done, and you will never look back. It’s like going from a manual car to an automatic; no one thinks it will be better, but 98% of people never return to manual.

How much does a regular boiler cost?

Prices range from £1,900 – £2,200

A regular, conventional or heat-only boiler, has three elements to it:

1. A boiler
2. A separate hot water tank (usually in an airing cupboard)
3. A separate cold water tank (often in the loft)

If you have one of these, then you will certainly know about it. If you don’t, then you never go into your loft.

These conventional boiler systems are usually best for larger homes with 3+ bathrooms as they are built for high hot water demand. We have two main options here.

Regular boiler installation costs

Here is a short conventional boiler cost guide to the ones currently on offer at Boiler Central. A direct regular boiler replacement is one of the best ways to keep costs down if this is the type of boiler you already have.

If you are thinking of converting from a conventional boiler and changing to a combi boiler, then read the rest of our guide for how much extra it will be to convert.

Regular boiler model	Cost
Ideal Logic+ Heat 24kW	£2,299
Ideal Logic+ Heat 30kW	£2,399
Viessmann Vitodens 100-W Regular Open Vent 25kW	£2,499
Viessmann Vitodens 100-W Regular Open Vent 35kW	£2,699

What else is there to know about regular heat-only boiler costs?

This option is for those who wish to replace their existing heat-only boiler. The cost does not include new hot or cold water tanks, as they typically last for decades and do not need to be replaced.

However, if you choose to include a new tank in your boiler replacement, expect to pay an additional cost of over £1,000 for the tank and labour. The price for a regular heat-only replacement boiler starts at £1,900 for a budget option with a low warranty, and ranges up to £2,200 and above for a mid to high-end option with a longer warranty.

Regular conversion to combi boiler cost & prices

Prices range from £2,300 – £2,500

The cost of converting from a conventional boiler to a combi boiler is similar to the cost of converting from a system boiler to a combi boiler. The main difference is that it involves removing the extra water tank.

However, it’s worth noting that sometimes it can be difficult to remove the cold water tank, as they are often located in the loft. Despite this, the conversion can be more economical in the long run and less dependent on factors such as a faulty boiler timer.

In older homes, access to the cold water tank may be limited, meaning that many cold water tanks are left decommissioned in the loft.

For a regular heat-only boiler conversion to a combi boiler, the price starts at £2,300 for a basic boiler with a low warranty and goes up to £2,500 for a mid-range boiler and some higher-end boilers.

Back boiler replacement costs & prices

Back boiler replacement costs are much higher than your average due to the fact you will have to have your back boiler removed and change to a different boiler type.

Government regulations mean it is not permitted to replace a back boiler with another back boiler. From 2005, no new back boilers are allowed to be installed, due to their inefficiency, high running costs, and maintenance issues.

Those looking for back boiler replacements can instead opt for a combi boiler, which provides both heating and hot water. Back boilers run at around 70% efficiency, while combi boilers typically run at over 90% efficiency — which could mean huge savings on your energy bills.

Therefore, the only price we will give you if you are thinking about replacing your back boiler is to switch to a combi boiler. If you do require a quote for a system or regular heat-only boiler, get a fixed online price here.

Back boiler to combi boiler costs

Prices range from £3,100 – £3,500

To update a back boiler to a combi boiler costs from £3,100 for a budget boiler with a low warranty. A mid to high-range combi boiler £3,200 and £3,500.

Most of the additional cost is due to the extra copper pipework; you need a boiler flue, and a waste condensate pipe — it’s a fresh new installation without the radiators.

Once you change from a back boiler to a combi boiler though, you will be adding value to your property, and the winters will be warm and cosy.

We offer some of the lowest prices on British Gas boilers such as Ideal which are designed and manufactured right here in the UK. If you change to one of these combi boilers from a back boiler you can save up to £580 per year on your energy bills right away.

If you get your new boiler from Boiler Central, you can make the expense more manageable by spreading the cost of new boiler installation over 5 or 10 years.

The back boiler was the modern day combi boiler. But like your youth, sometimes you have to re-live it in a new old fashioned way

Boiler installation labour costs for heating engineers

As the cost of a boiler installation is mainly labour, the time it takes will affect how pricey the job will be.

You can work out the hourly rate if you like, but most engineers will charge a fixed rate for the day’s work.

You must ensure that you get a quote beforehand that includes everything. That’s the labour, parts and the boiler itself.

Here are typical boiler installation costs for UK residents:

• 1 day installation: £400 to £500
• 2-day installation: £700 to £1,200
• 3-day installation: £1,000 to £2,000

It is rare for jobs to go into three days, but it does happen, so be prepared to pay the rates above, which are the going retail prices for new boiler installation costs in the UK.

Labour makes it sound like hard work, but our fully-trained expert engineers can do their job with their eyes closed (they won’t mind). So don’t feel too sorry for them. Unless they’re taking out a tank in the loft in August maybe.

What is the average cost of a new boiler fitted in the UK?

• Average combi boiler cost: £1,800
• Average system boiler cost: £1,950
• Average regular (heat only) boiler cost: £2,100
• Average Megaflo cost: £1,900

Prices are based on UK average boiler fitting cost from Autumn 2022

Remember, these are Uk average new boiler fitted cost figures for illustrative purposes, therefore the actual price you will pay to get a boiler installed and fully working on your property depends on the boiler and the specifics of your boiler installation.

How long should a new boiler last?

Answer: A new boiler purchased from 2023 onwards should last at least ten years, but with an expected life of 10 to 15 years at high efficiency.

Boiler installation cost & prices overview

The cost of boiler installation is included in your fixed price when you price up your boiler with Boiler Central.

You can even spread the cost of a new boiler with our boiler on finance options.

Some companies offer boiler-only installations such as Screwfix.

Still, you will not get the same warranty as if the boiler and installation are carried out by a boiler company such as Boiler Central.

On average the cost to install your new boiler will be between £400 and £800, depending on the type of installation.

For example, if you have a simple combi boiler replacement, then the time to install the boiler will be much quicker and usually a one-day job.

A back boiler conversion to a combi boiler will usually be a two-day jobs, and a system boiler conversion to a combi boiler can take either one or two days.

What is included in the cost of a boiler installation? 

Several different factors influence the cost of a boiler replacement for properties in the UK.

On the surface, it may seem like it is just the labour cost and the cost of the unit itself — however, several factors add to the price of a new boiler, so let’s delve into these in further detail:

New boiler	£1,000
Labour	£500
Horizontal flue	£100
Condensate pipe	£20
Copper piping	£300
Fixings	£50
Magnetic filter	£100
Limescale reducer	£50
Central heating inhibitor	£20
Vertical flue	£300
Thermostat	£50
Wiring & electrics	£100

The price of a new boiler itself

Of course, there is only one place to begin: with the price of the unit itself.

The price of a boiler differs by hundreds of pounds, if not thousands, as it all depends on the quality of the boiler, as well as the boiler brand, kW, size and model.

The typical unit price is anywhere from £400 to £1,800, depending on the model and boiler manufacturer.

However, there are some much more expensive units on the market today, such as the Megaflo unvented boiler range.

The cost of labour from a Gas Safe heating engineer

When swapping an existing combi boiler for a new combi boiler, the cost of labour is anywhere from £600 to £800 on average, depending on the size of your home and what size boiler is required to heat your home.

The labour cost of a conversion from a system boiler or regular boiler to a combi boiler tends to be between £1,000 to £1,500. If your boiler installation is in London, or in a remote area, they may charge extra.

Labour is included in your fixed price at Boiler Central, so no need to worry about hidden costs.

For many years, heating specialists were watched over by the official watchdog CORGI (the Council of Registered Gas Installers).

The CORGI brand was synonymous with quality and safety, thankfully that changed between 2009 and 2010 when the Gas Safe Register replaced CORGI which is much more reliable.

People don’t realise how important controlling the boiler is. A smart thermostat can be the ultimate tool for greater control. It can also cause arguments, so be careful who has access to the app.

New heating controls & smart thermostat cost: £30–£300

Thanks to upgrades in technology in recent times, boilers can be turned on and off with ease.

You do not have to walk to the boiler to make changes.

Smart thermostats such as Hive or Nest control your boiler and give you updates on how much energy you are using.

Depending on the brand and type of the controller, it is going to add different figures to the new boiler price.

Boiler relocation costs (moving a boiler): £200–£600

You may need to move the location of your boiler for many reasons.

Relocating is going to cost more money, which is going to require several new fittings and fixtures, as well as emotional robustness, additional pipework, and a lot of physical labour. Unless moving your boiler is vital, it is usually a good idea to avoid this.

If your current boiler is a back boiler, then back boiler removal is essential. It’s not permitted to install new back boilers, so it will need to be replaced with a combi, regular or system boiler.

If you are moving your boiler from the kitchen to the next room then it will around £200. However, if you are moving the boiler from the kitchen to the loft, then the moving boiler cost will be £400 to £600.

If you get a new boiler quote from us, your gas supply pipes are included in your fixed price; however, other companies may charge several hundred pounds to upgrade your gas supply pipes.

Plume Kit: £75–£150

A plume kit is an extension kit that attaches to the flue of the boiler. They can be required when your boiler flue is too close for comfort to your neighbouring properties, door, or window. This is to ensure it complies with Gas Safe regulations.

The typical cost of a plume kit for your new combi, regular or system boiler is anywhere between £75 and £150.

With Boiler Central, your fixed price includes the plume kit.

Chemical flush: £50–£150

You may also need to pay for a chemical flush. This can be anything from £50 to £150.

Flushes help to get rid of any existing sludge from your heating system. Sludge can prevent the hot heating water from flowing efficiently around your radiators if you do not clear it. If your radiators are cold at the bottom, a deep clean is going to be required.

The most common and standard cleaning option is a hot, chemical flush.

For a power flush, you can pay more than £500 with many boiler companies.

Be careful with these: they work by forcing high-pressure water through a heating system, which can do more harm than good especially in older systems. It can cause debris to move about that was not causing an issue before.

Then you’re left with a new boiler that has issues with the system because it was power flushed when it didn’t need to be and you are free to fit a limescale reducer to keep your central heating system clear.

Again, with Boiler Central, your fixed price includes a free chemical flush that will not harm your system.

Boiler flue: £50–£200

A boiler flue is a big piece of pipe that leads from the boiler to the outside.

The flue makes sure that the flue gases and condensation are pumped outside and not into your home.

Most of the time, the flue is going to leave your home horizontally, which means that there are no extra expenses.

However, flues that leave vertically through your roof demand much more work, resulting in more expenses.

The average cost for a boiler flue is anywhere from £200 to £500, dependent on the length required and type.

A vertical flue is generally more expensive than a horizontal flue.

An engineer is required by law to fit a brand new flue when they install a new boiler, and at Boiler Central we include it in your fixed online price.

Magnetic boiler filter: £100–£200

The average cost of a magnetic boiler filter is between £100 and £200

Magnetic filters are installed inline on the pipework, helping to protect your boiler, and some companies will include them in their pricing.

They utilise powerful magnets that trap small particles of metal and dirt, stopping them from going into the boiler itself and causing unnecessary boiler leaks and damage.

A quality boiler installation specialist is always going to put together the full cost of a filter into your final quote.

You should not be stung with added expenses at the end. At Boiler Central, we install magnetic filters free of charge as they are included in your online fixed price.

Worcester Bosch boiler prices

Price ranges from £1,800–£3,600

If you’re looking for good reasons to select one of the Worcester Bosch range of boilers, there are quite a few to choose from.

Worcester boiler installers are very experienced in extolling the virtues of their favourite type of boiler, but they’re right when they say that the boilers are excellent.

Perhaps one of the immediate selling points for people considering a Worcester combi boiler is that it has received the Which? ‘Best Buy’ award for six years running.

This award is given based on independent customer ratings, so you can be assured that it is well-earned.

Worcester Bosch boilers are also one of the most versatile ranges on the market, with sizes that will fit all properties, including an excellent range of boilers that will fit neatly into kitchen cupboards.

The prominence of Worcester Bosch in the marketplace means you’ll find that your repairs are done swiftly and without too much waiting around for parts.

It’s popular in the UK for those looking for an old boiler replacement, as it works perfectly in “cold climates”. As long as the boiler installation is carried out correctly, there is zero risk of pipes freezing during the winter months.

You can pick up a Worcester Greenstar combi boiler for between £1,750 and £2,900 depending on the model you choose.

If you want a really powerful boiler, check out the Worcester Bosch 8000 boiler.

The ‘CDi‘ range is similar to the ‘i’, but it’s the top-performing gas combi boiler in the Greenstar range — offering the highest hot water flow of all wall-mounted boilers.

You can get different power outputs for CDi boilers, with prices ranging from around £1,418 to £2,400.

Viessmann boiler prices

Viessmann is one of the latest boiler manufacturers to take the UK by storm, offering some of the best combi boilers on the market. Viessmann boiler prices are low, yet they offer superior quality and build, making them superb value for money.

Their Viessmann Vitodens 100-W combi boiler is the best-selling boiler in Europe and is a great-value premium boiler.

If it’s value your looking for, then look no further than the Viessmann Vitodens 050-W combi boiler.

The Viessmann Vitodens 050-W combi boiler costs around £2,050 with full installation. This is an absolute steal considering that you get 10 years warranty as a standard.

This means that you get 12 years warranty instead of 10 for exactly the same price.

Since releasing the updated versions, the Viessmann range quickly became one of our best-selling boilers. It’s also cheaper and more compact than its direct competitor, the Worcester Bosch 4000.

Vokera boilers prices

Price ranges from £1,650–£2,200

Like many other boiler manufacturers, Vokera has a range of both system boilers and combi boilers.

Most of these combi models are compact, meaning they are ideal for putting into the kitchen cupboard of a small flat.

Ideal boilers prices

Ideal boiler prices range from £1,700–£2,600 depending on the model you choose.

Their Logic+ range of boilers are considered among the best and most popular models available today in the UK.

This range of boilers has won numerous heating awards, including ‘Product of the Year’ titles within boiler categories. ‘Good Housekeeping’ readers and the Energy Saving Trust have also recommended it.

Ideal are so confident in their exceptional quality, that they offer a seven-year warranty on any Logic+ boiler.

The Ideal Logic+ series has other notable installation features such as built-in frost protection. Its compact size makes it perfect for kitchen cupboards.

Ideal also provides other ranges such as the Ideal Vogue, which comes with a mighty 10-year warranty.

It’s no surprise that Ideal is so famous and synonymous with quality heating.

At the lower end of the range, you have the Ideal Independent Combi boilers, which are between £1,700 and £1,780.

If you’re looking for something with a higher power output, the Ideal Vogue Max or Ideal Logic Code Combi are both excellent options.

The former is priced between £1,109 and £1,340 without installation.

The Ideal Logic Code Combi is on the market for between £1,000 and £1,330 without installation.

Overall, we would recommend the Ideal Logic combi C30 boiler.

Let’s wrap the prices of new boilers up:

As you can see, prices do differ dramatically depending on the type of boiler that you opt for and the quotes that you get for your new boiler installation.

Prices vary depending upon multiple things, and you should seek additional boiler advice if you are still unsure which boilers are suitable for your property.

If you’re looking for a boiler that’s different and you have the spare cash you could have a look at ATAG boiler prices. ATAG boilers come with a market-leading 14-year warranty, and they’re the only boiler company in the UK to offer this.

A lot of the expense comes from the installation, yet this is an essential part of the process, and you need to make sure you select a professional with care. At Boiler Central, we only use Gas Safe registered engineers who are experienced and qualified in the boiler they are installing. And each job is audited internally to ensure that our standards for quality and workmanship are met.
