New Boiler Cost – How Much Is It? Compare Boiler Prices & Quotes
If you’ve ever run into boiler trouble, the instant feeling of dread won’t be new to you. Beyond the immediate thought of “how much is this going to set me back?” and “how long am I going to be without hot water or heating?”, a broken boiler can be downright dangerous. So, for those of you fortunate enough to have not experienced this yet: the second you start to hear that tapping noise, or even just notice that your water pressure is low, DO NOT IGNORE IT!
Although boilers are much safer these days, even modern systems can be a serious health and safety risk left unattended. As well as the possibility of carbon monoxide through gas leaks and leftover fuel not being fully burned, if enough pressure builds up in the system, a faulty boiler can explode, causing catastrophic damage to the surrounding area and even death. With that in mind, if you have any concerns about your current boiler, don’t wait around.
Calling someone out to repair it is one thing but, as many of us know, this can often become a regular occurrence. Whilst the technicians sent out by your energy suppliers are trained professionals, what they are able to do might turn out to only be a temporary fix. In some cases, you might be charged a call-out fee only for them to come and tell you that you need a new one altogether – so why prolong the inevitable? That being said, how much is a new boiler?

Let’s compare boiler prices
Whilst this obviously depends on the kind of system you have, the price margin you’re looking at varies from anywhere between approximately £1,000 and £4,000 to replace your boiler. This accounts not only for the new system itself, but the labour costs and installation fee you can expect – but we’ll come on to that shortly.
When you compare boiler quotes, it worth remembering that you don’t have to go through the company you have chosen as your energy provider. For example, external companies like Heatable offer straightforward combi replacement starts from £1,696. In contrast, in scouring the internet, we found that when going through mainstream providers like British Gas, EDF, Utilita and so on, people have been quoted as much £5,000 for a brand new boiler, including the installation fee.
With all-told prices like that, local and/or independent is often the way to go, especially if you aren’t already covered by a supplier’s warranty or home-care plan.
So, let’s look more specifically at how much does a new boiler cost for each type of system:
*Please note, that these are rough estimates and will obviously fluctuate depending on the brand, model, supplier etc.*
In fact, there are a lot of varying factors that will determine how much you end up spending on your new boiler. For instance, even though a conventional, heat-only boiler obviously provides a limited source of energy and can therefore be the cheapest option, depending on how large your home is and the subsequent size of boiler you need to heat it, the price can vary from anywhere between £500 and the top end prices of £3,000+.
Installation & Labour
This is all before you take installation and labour costs into account; replacing a boiler isn’t really a DIY task. Because of the complexity of these systems and the risk, you need trained professionals to do the job and they don’t come cheap.
The average cost for a technician to come and fit a new boiler varies from £500 to £1,000 – add that on top of your initial costs for the boiler itself and you start to understand exactly why people fear a faulty boiler so much.

This list is by no means a comprehensive list and keep in mind, these recommendations might not necessarily be suitable for you. You first need to decide whether you’re looking for a combi, conventional or system boiler – that way you can narrow down which models are the best for you.
Is it worth getting a new boiler?
The short answer is yes. Whilst it will no doubt be cheaper in the short-term to simply call someone out to fix your existing boiler, there is no guarantee that the repairs they make will be long-lasting or even possible to begin with. As mentioned, many people end up paying out a call-out fee for nothing other than to be told their boiler needs replacing. Moreover, you can end up paying more in the long run if your boiler continues to break and you keep paying for repairs. A stitch in time saves nine.
When should you replace your boiler?
There a few different ways to determine when it’s time to replace your boiler. Here’s a quick breakdown of a few of them and we’ve split them into three levels of severity – that way you know the level of concern and how quickly you need to act:
- If you see black, yellow or green stains around your boiler and/or pipes
- If you see scorch marks, dripping or considerable leakage.
- The pilot light is continually going out or burning yellow instead of blue.
- If you smell gas and/or experiencing headaches and nausea when the boiler is running
- If this occurs at any time, turn off the gas supply using the shut-off valve and call National Gas Emergencies immediately: 0800 111 999
- Regularly breaks down or has recurring issues.
- Regular overheating.
- If the pressure reading is too high: above 2 bar (the red zone).
- You hear any of the following sounds: tapping, pinging, creaking, banging, churning or humming louder than is typical. This can be the result of build-up and blockages in the pipes.
- Boiler won’t turn on at all.
- Your boiler is 15+ years old.
- Water pressure is low – this can also be a result of build-up and blockages in the pipes.
- Your energy bill is shooting up without explanation (here’s a hint: your boiler is the reason).
- You have a non-condensing boiler – modern condensing boilers have been the standard since 2005 and, barring a few exceptions, the former is technically illegal.
Can I get a free boiler replacement?
In some cases, yes. The UK government has an ECO (Energy Companies Obligation) grant scheme, which can provide a free boiler replacement for those who are eligible. To qualify for this scheme, you must be signed up with one of the ‘Big Six’ energy suppliers:
- British Gas
- SSE (Scottish and Southern Energy)
- Scottish Power
- EDF (Electricite de France)
How do I know if my boiler is efficient?
First of all, you need to check your EPC rating. Most modern boilers should have an EPC sticker on them, with a letter grade for A-G. Grade D is the average for most UK households and D-E is considered acceptable across Europe, but anything below should be a serious cause for concern.
Ideally, you are looking for Grade D and above. Whilst other improvements such as insulation and glazing can help improve your rating, replacing your boiler is the most sure-fire way to get those bills down.
Another easy way to identify whether your boiler is worth its salt is to identify the make and model number. A simple Google search will pull up enough information and first-hand reviews from people who have experience with your boiler to find out whether you can do better.
How efficient is a 20-year-old boiler?
In all honesty, if we’re talking about a boiler that is 20 years old, it should have been replaced a while ago. Leading manufacturers, Viessmann, estimate that the average modern boiler last around 10-15 years; moreover, your boiler can make up approximately 55% of your overall energy bill, so the chances are you’re paying more for your hot water and heating than you need to be. If this is you, it’s time to replace.
Are British Gas boilers expensive?
Yes. British Gas (1) may be the most well-known energy provider in the UK, but their reputation also comes with the highest price point. Of the ‘Big Six’ energy suppliers, British Gas often comes out at the most expensive year in, year out, and you’ll find the same if you compare boiler quotes.
While their all-round service, boiler maintenance and HomeCare coverage is highly-rated and comes with few complaints, you’re also likely to pay a premium if you go through them to install your replacement boiler.
How long should a combi boiler last?
Approximately 15 years. Compared to conventional heat-only and system boilers, which tend to falter a few years earlier, combi boilers are more efficient and, as such, can even last beyond 15 years. However, this is not a guarantee and – for the sake of safety and overall efficiency – you should always look to replace your boiler once it surpasses the estimated life expectancy.
How much money can you save with a new boiler?
When it comes to replacing a boiler, your potential savings in the long-run are greater the earlier you decide to address the problem.
Let’s say you had some kind of boiler trouble once every five years. The average boiler service cost ranges from £150 to £400, depending on the severity of the issue, of course. Simple maths will tell you that, in this eventuality, you could be spending anywhere from £450, all the way up to £1,200 on boiler repairs in your boiler’s rough, 15-year lifespan.
These numbers could be even greater if you were unlucky enough to suffer even more frequent boiler trouble (it does happen) – and that’s just in regards to maintenance. In terms of energy usage, once your boiler is over 10 years old – no matter the type or initial quality of the model – your boiler can drop to as little as 70% efficient, if not lower. That’s why the sooner you upgrade to a new boiler, the more money you can save.
Once again, Heatable estimates that replacing/upgrading to a combi boiler, for example, can lead to as much as 20-35% off your annual gas bill. To put this into perspective, the average UK household spent roughly £610 on gas in 2019, with prices likely to go up across the board every year. If your usage is somewhere around that figure and you’ve had your current boiler for a decade or longer, this could be saving you anywhere between £122 and £213.50 by simply renewing your boiler.
How long does my landlord have to replace my boiler?
If you’re renting, fortunately, you only half as much to worry about. By law (2) (3), your landlord is responsible for sorting any and all issues with your boiler. More importantly, if emergency repairs are required – i.e. you are completely without hot water or heating – they have no more than 24 hours to get it fixed.
Be proactive, not reactive
Whilst it might feel like a significant outlay to spend in one go – especially if you haven’t yet encountered any noticeable problems with your boiler so far – but as the figures show, it really does pay to be proactive.
What’s more, it’s not just the boiler itself and the overall savings your investing in: it’s the peace of mind. There’s nothing like not having to worry about a sudden and potentially dangerous issue, that comes at a greater expense and risk to you the longer it’s avoided.
We hope you found this article helpful. No one can really afford to go by without heating or running hot water for more than a couple of days at most, and no one should have to. So don’t wait for the problem to get out of control and become even more costly than it needs to be.
