Here are some benefits that outweigh the price of a new boiler
You will typically find that you will make your money back in terms of the efficiency savings that you will make by getting a new boiler.
A new A-Rated boiler will maybe set you back on average £2,000 (this is a very average price range and varies so much on the type of home and boiler required)
The Energy Saving Trust state that by getting a new A-Rated boiler you can save up to £340 per year. Over 10 years that will pay back the cost outlay of your new boiler.
That doesn’t sound too bad does it?
Nevertheless, you will obviously want to know how much money you are going to need to save to purchase a new boiler.
Last year, boiler breakdowns cost the UK £787 million which is quite staggering.
However, the trouble is that people think boilers are too expensive so they keep running them, getting them fixed and spend hundreds or thousands on repairing them.
If you shop around, you will find that boiler replacement costs can vary considerably and are much cheaper than you first thought.
So, how much does a new boiler cost in 2020?
Research shows that the highest price for a boiler in the UK was £7,764 and the lowest was £1,500.
This shows why it is important to search around for the best boiler prices for your home as the price varies so much.
There is also a difference for the installation costs and also the type of boiler you require, such as a combi, system or regular heat only.
This highlights why you need to search with care to find the best boiler prices.

What is a combi boiler?
Before we delve deeper into the costs, it’s firstly important to explain exactly what a combi boiler is.
This is a combination boiler and shouldn’t be mixed up with a conventional one. If you need help on what a conventional boiler is then our guide on what is a conventional boiler will help.
It controls both your heating and hot water, delivering them both instantly whenever you need them.
You “do not” need to have a hot water cylinder heated.
Combi Boiler Replacement – How much do they cost in 2020?
Combi boiler replacement varies from £1,500 to £3,500.
This includes both the cost of the unit itself, as well as the new installation costs.
There are a number of different factors at play here:
This includes the area in which you live, the labour costs, how complicated the required installation is, and the sort and size of boiler that you need.
- If you live in London, you can expect to pay more when getting your unit installed.
- If your requirements are complicated, then the new boiler costings are going to be complex!
- If you opt for a premium boiler, you are going to have to pay a premium price – you get the point!
How much does regular boiler replacement cost?
Regular boilers, otherwise known as system boilers, can cost anything from £1,500 to £3,000.
For those who are unaware, this type of boiler is essentially the opposite of a combi boiler.
This means that there is a separate tank, which is typically in the loft, and a separate water cylinder, which is usually in the airing cupboard. Megaflo offer unvented system boilers and are a recognised industry brand.
These sorts of boilers do not provide cold water and hot water on demand, which is why many people have made the move to a combi.
Again, there are going to be a number of different factors that determine the total cost.
As well as boiler warranty length and the complexity of the job, you also have to consider whether any added pumps are needed and required controls.
Replacing a standard boiler to a combi boiler?
If you want to make a boiler replacement from a standard boiler to a combi, this can cost anything from £2,500 to £4,500.
To understand why this is more expensive than just having a boiler installed from scratch, there are a few things to consider here, and it ultimately comes down to all of the work that is included.
- The water cylinder and old boiler are going to need to be fully removed.
- There also needs to be new upgraded pipework, which is fed into the new location of the incoming boiler or existing location.
- Then, you actually have to have the new combi installed, and this is the simple version.
This is a big job, and it will often require around two days of work, so you can see why it is expensive.
However, if you have the budget, a lot of homeowners will tell you that making the switch is the best decision they ever made long term. ?
This is not only because they get hot water the minute they need it, you also get great efficiency savings as well, which means you put more money in your bank account.
Here are some benefits of replacing your old inefficient boiler with a new one:
- Lower costs – You will not only save money on your energy bills but you will also be able to reduce expenses when it comes to maintenance.
- Nobody is going to have to go to the roof in order to fix any boiler problems.
- Mains pressure water – Hot water will be delivered through your shower and taps at mains level power, enabling you to enjoy high power showers.
- Save space in your property – If you combine a central heating boiler and a water heater into one unit, you are going to reduce the space that is needed considerably.
What impacts the price of boiler replacement?
There are a number of different factors that influence the cost of a boiler.
On the surface, it may seem like it is just the labour cost and the cost of the unit itself.
However, there are a number of factors that add to the price of a new boiler, and so we are going to delve into these in further detail.
The price of the 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.
It all depends on the quality of the boiler, as well as the brand, kW size, and model.
Later in this guide, we are going to take a look at some specific brands of boilers, as well as the average cost of these boilers.
The typical unit price is anywhere from £400 to £1,800 dependent on the model and manufacturer.
However, there are some much more expensive units on the market today such as the Megaflo unvented boiler range.
The cost of labour to fit your boiler
For a boiler swap, the cost of labour is anywhere from £600 to £800 on average. This depends on the size of your home and what size boiler is required to heat your home.
The cost of conversion on average tends to be between £1,000 to £1,500. For example a back boiler swap or conversion.
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.
If you got a CORGI engineer in to perform a new install, you knew you’d be getting quality work done.
However, CORGI wasn’t mandatory and was a voluntary registration scheme. That meant there was a whole load of heating specialists out there fitting combis who weren’t registered.
Thankfully that changed during 2009 and 2010 when the Gas Safe Register replaced CORGI.
This made it mandatory for all central heating combi boiler installation costs and servicing workers – including those performing combi boiler repairs or boiler installation jobs – to be registered.
In order to be part of the registry, combi boiler installation experts have to have the proper qualifications to work on any boilers. So always ask to see your installer’s Gas Safe Register card for proof of their credentials.
Upgraded warranties of up to 15 years
In addition to the costs that have already been mentioned, extended warranties, especially ten-year warranties in most cases, are only able to be provided by trusted manufacturers and partners.
They can sometimes rely on additional approved equipment being fitted.
For example, magnetic boiler filters. They will tend to results in additional costs being added to the installation.
However, there is no denying that a longer warranty is an expense that is worth incurring. It could end up saving you a lot of money in the long run!
Upgraded heating controls including smart thermostats
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 in order to make changes.
Depending on the brand and type of the controller, it is going to add varying figures to the new boiler price.
The average price of this is between £100 and £300.
Relocating the boiler replacement
You may need to move the location of your boiler. This is going to cost more money, which is going to require a number of 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.
You can upgrade your gas pipes to new, more efficient ones
You may also need to have the main gas pipe upgraded.
A lot of the older heating systems are constructed using gas piping of a width around 15 mm.
However, in order for modern regulations to be met, these pipes need to be upgraded to 22 mm in most cases. This can sometimes cost more money.
In most cases, older pipes will also be made from lead, and so they will need to be replaced using copper piping.
You need to be cautious of rogue traders who do not plan to upgrade the pipework. This would be an illegal installation, and so while it may be cheaper, it is certainly not worth the risk – that much is certain!
Free plume kits are included in most installs
A plume kit is basically an extension kit that attaches to the flue of the boiler. This 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 £90 and £130.
Chemical flush is sometimes included to flush your system out
You may also need to pay for a chemical flush. This can be anything from £100 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 really need to be flushed.
A brand new boiler flue is mandatory as per law (and included in your price)
A boiler flue is basically a big piece of pipe, which leads from the boiler to the outside of your property.
This makes sure that the flue gases and condensation are pumped outside and not into your own face. Pretty important, right??
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. This can just be plain bad luck.
The average cost for a flue is anywhere from £100 to £600 dependent on the length required and type.
A vertical flue is generally more expensive than a horizontal flue.
Magnetic boiler filter costs
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.
Here are the leading gas boiler brands in UK and the average cost for new replacements:
Below, we are going to take a look at some specific boiler makes, as well as the average costs.
£1500 – £3,600
