£2,000 for a new boiler. Divide it by 12 years warranty, that’s £166 a year for peace of mind

New gas boiler costs continue to rise slowly

Every year on year as inflation kicks in prices is likely to change in the world of boilers and homeowners become less and less inclined to spend, especially with landlords increasing rent for tenants and going out becoming extortionate. Thinking about buying a new gas boiler can become a worry.

Luckily the market is very competitive with a wide range of products giving you, the customer more choice and a greater chance of striking some great deals on the latest boiler models, and surprisingly in the UK, we haven’t seen boiler installation costs rise significantly over the years so as much as they are a large purchase for most people, you can still find one within your budget.

As the winter arrives and there is a higher demand for boilers, expect another change in the prices as demand soars and potential stock issues hit the UK market, and ideally the best time to install a boiler in the summer months when installation costs are lower and demand is lower too so you can always get the boiler that you need.

Can a new boiler save you money?

Yes. a new boiler can save you money by lowering your gas bills. Older boilers generally become less energy efficient, especially if they have not been serviced for a while. While we understand new boilers cost a fair penny or two, you could get a boiler service that can help keep your older boiler more energy efficient but as technology improves, investing in an A-rated energy-efficient one will likely be a better option than trying to salvage an old one.

This is mainly down to the amount of work required by the Gas Safe registered installer/s to complete the work and whilst changing a boiler can help cut down on energy usage which is massive at the moment, the actual combi boiler replacement cost is higher if you are converting.

2. System to combi boiler 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 on building the property back when the pound sterling was worth much more. 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 in the majority of homes heats the water, which is then sent to the hot water storage tank that is usually found in an ‘airing cupboard, and once the demand for hot water is required for say a bath, 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 that require a higher demand for hot water, and would only typically be installed in homes with 3+ bathrooms as a minimum, and in comparison, any less than this and a combi boiler would be perfect.

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.

3. System boiler replacement costs (swap)

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

The price of a system boiler is where you would replace only the boiler (not the tank).

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 £1,900 to £2,900 model and manufacturer-dependent.

New system boiler replacement costs are mostly made up of the actual system boiler itself, fitting, and labour.

4. System boiler conversion to a combi boiler prices

Prices range from £2,300 – £3,000

As you can see, the main downside to this is the cost of boiler replacement is higher, 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 will take the installation team usually two days to finish the job. Make sure you get the best system boiler for your home’s heating requirements.

It’s rarely one day, and it’s not often three days, so we are confident in the 2-day statement above and we ensure full removal of your hot water tank is included in the cost plus disposal.

As we all know, labour is one of the most expensive parts of most service-type 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 is 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.

It’s the same scenario here; trust us.

5. Regular boiler replacement cost & prices

Prices range from £1,900 – £2,200

A regular, 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 price guide to the regular boilers 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 looking at changing to a combi boiler, then read the rest of our guide for how much extra it will be to convert.

Regular boiler modelCost
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 if you just want to replace your boiler with your existing heat-only system.

The price does not include new hot or cold water tanks as, in most cases, you do not need to pay for a new one.

That’s because they last for decades.

You can get a tank included in new boiler costs but expect to pay over £1,000 for the tank and labour.

The price for a regular heat-only replacement starts at £1,900 for a budget boiler with a low warranty, to £2,200 and above for a mid to high-end heat-only boiler with a good length warranty.

If you want to change to a combi boiler, see below:

6. Regular conversion to combi boiler cost & prices

Prices range from £2,300 – £2,500

Changing from a conventional boiler to a combi boiler option costs around the same as a system boiler to combi boiler as all that’s required are the extra water tank that needs removing.

It’s worth noting that sometimes it’s difficult to remove the cold water tank as they are mostly in the loft but it can be much more economical and less reliant on things like a faulty boiler timer.

Homes back then were built around the heating system, and the access is usually far more limited than the tank, meaning we have to leave many cold water tanks decommissioned in the loft.

So, for a regular heat-only boiler conversion to a combi boiler, the price is £2,300 for a basic boiler, with a low warranty, or slightly more expensive at £2,500 for a mid-range boiler and some higher-end boilers.

7. Back boiler replacement costs & prices

Firstly, you can’t replace a back boiler with another back boiler. Back boiler replacement is not allowed due to regulations.

They are against regulations to install from new. It’s perfectly fine to use an existing one, but you can not install a new one.

Why would you anyway?

You wouldn’t – they are expensive to run, dirty, unreliable, and a pain to keep going.

Most people who have a back boiler replaced with a combi boiler and all their heating and hot water dreams come true.

Therefore, the only price we will give you is to switch to a combi boiler. If you do require a cost for a system or regular heat only, get a fixed online price here.

Back boiler to combi boiler costs

Prices range from £3,100 – £3,500

To change a back boiler to a combi boiler cost £3,100. This is for a budget boiler with a low warranty through to £3,200 and £3,500 for a mid to high-range combi boiler.

ideal british made gas boilers

Most of the additional cost is due to lots of new 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. For the investment, it’s certainly worth it.

We offer some of the lowest prices on British gas boilers such as Ideal which are designed and manufactured right here in the UK and 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 spread the cost of new boiler installation over 5 or 10 years, so the £3,100 plus for this option is manageable spread over 120 months. View your boiler finance options here.

Boiler installation cost & prices: Overview

The cost of boiler installation is usually included in your fixed price that is quoted to you online if you choose to price your boiler up 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 less than a two-day job.

These 2-day jobs are installations such as a back boiler conversion to a combi boiler, or sometimes a system boiler to combi boiler.

For 2 day installs you need labour for 2 days as opposed to 1 day as above.

What impacts the cost of a boiler replacement? 

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, and so we are going to delve into these in further detail. If you are a landlord looking for a great deal on a boiler for your rental properties, then check out our boilers for landlords with a great offer for multiple installations.

New boiler£1,000
Horizontal flue£100
condensate pipe£20
Copper Piping£300
Vertical Flue£300
Wiring & electrician£100

The price of a new boiler itself

Of course, there is only one place to begin, and this is 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, dependent 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 and Gas Safe boiler installation

For a boiler swap, the cost of labour to install the boiler 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 price is included in your quote so don’t worry, it will not be added on top of your fixed cost, so no need to worry about the hourly rate your Gas Safe engineer is on if you boiler installation is in London.

The labour cost of conversion on average tends to be between £1,000 to £1,500, for example, a back boiler swap or conversion depending on where you live.

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 controling 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

New heating controls

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 always a good idea to avoid this. If you are going down the back boiler removal and replacement route then you must now convert to a combi, regular or system boiler.

Q What kind of fuel does your boiler use?

If you get a new boiler quote from another company however they may charge you 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.

Plus, it must comply with Gas Safe regulations by law.

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. There are a lot of different options when it comes to this.

However, the most common and standard option is a hot, chemical flush.

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

Be careful with these, as they can often do more damage than good by forcing high-pressure water through a heating system, especially if it is an old one. It can cause debris to move about that was not causing an issue before.

Then you’re left with a new boiler that’s got issues with the system because it was power flushed when it didn’t need to be.

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 face.

new boiler cost guide

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 £500 to £200, dependent on the length required and type.

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

With every new boiler installation, you need a new boiler flue as per regulations, and at Boiler Central, we include one included in your fixed online price.

Magnetic boiler filter: £100 – £200

Boiler filter (Cost)

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

Filters are installed inline on the pipework, helping to protect your boiler, and some companies install them included in your price.

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.
