How much does a new boiler cost in 2020?
The new boiler costs in this article are correct as of 2020
Our boilers are the overlooked heroes of our homes, quietly working away to give us hot water and toasty radiators whenever we need them. When a boiler is working perfectly, we don’t even think about them, but if something goes wrong, we soon notice it - especially when the weather outside turns chilly. If regularly inspected and maintained, a good boiler should keep going for years, but if yours is old, faulty, or has been badly looked after, the time may have come to invest in a new one. This article breaks down the typical new boiler cost and boiler replacement cost you can expect if you need to upgrade.
Do I need a new boiler?
Much like cars, there comes a point with boilers where at some point it becomes more cost efficient to replace it entirely than to keep repairing it to keep it running in the short term. As boilers get older, their issues can become more and more expensive to fix, so replacing it becomes more sensible than fixing it.
Even if your boiler is still functioning, it is likely that it will become less efficient over time. Boilers should have a lifespan of at least 10 years, but towards the end of that time they are likely to become less efficient, working harder to produce the same results, meaning you’re spending more money on your bills. Boilers have also become more advanced in recent years, so even cheaper new models can be vastly more efficient that models produced a decade ago. If yours is around 10 years old and starting to struggle, then it could be a good time to consider buying a new one.

How much is a new boiler?
The average cost of a new boiler can range from around £1,500 to £2,000, depending on the type of boiler, the model you choose and its efficiency rating, and whether or not there are complications with installing it (for example, you are replacing one type of boiler system with another).
There are three main types of boiler you can have in your home - combi boilers, traditional boilers (also known as traditional, regular, heat only or open vent boilers) and system boilers. You may also hear the term condensing boiler, but by law, all types of boilers must now be condensing boilers.
- Combi boilers: The most common type of modern boiler and usually the most cost-effective for most homes is a combi boiler - short for combination boiler. They heat water directly from the mains rather than storing heated water in a tank, meaning there is no limit to the hot water supply, while not having a tank means they are relatively compact to install. They are usually rated well for energy efficiency as well.
- Traditional boilers: Traditional boilers feature a hot water cylinder, usually in an airing cupboard, and a tank of water in the loft which feeds the system. They can be useful for homes with more than one bathroom or where water pressure is very low. If your home has an old central heating system based on this, it is usually easiest to replace like-for-like.
- System boilers: Like traditional boilers, system boilers have a hot water cylinder, but this is all contained within a single boiler unit like a combi boiler, with no need for a separate water tank. This is useful for saving space and ease of installation, and can be good for homes which use a lot of water.
Combi boiler costs
Combi boiler prices fitted are typically more expensive up front than traditional boilers, though work out cheaper in the long run than traditional boilers. A new combi boiler will usually range from around £1,800 to over £2,000, including installation fees, which will normally be included in the purchase price. This is the price for a straightforward combi boiler replacement - if it is being moved, then expect to pay more, potentially £500 to £1,000 extra depending on how complex the change is. It is always worth shopping around and trying to find the model that will work best for you and your home.
Gas boiler costs
The average cost of a new gas boiler is around £1,500 to £1,800. This is the cost of a new gas boiler fitted, so includes installaion. They can be bought from a variety of places, with the cost of installation typically included. Always do your research beforehand into different models to see what is available, and how they are reviewed, and if they have any particular features you’ll find useful. Shop around to get the best price. As with combi boilers, moving any of the elements during the installation will increase the overall price.
System boiler costs
The cost of installing a system boiler is fairly equivalent to that of a combi boiler - around £1,800 to £2,000. However, if you are replacing either a combi boiler or traditional boiler with a system boiler, the costs will be a lot higher - with the final costs being between £4,000 and £5,000 for the full installation.
MyBuilder Top Tip
When buying a new boiler you should always look at its energy efficiency, and ideally target an A-grade high efficiency model. If your current boiler is more than ten years old it is unlikely to be as efficient as more recent models, so you should always try to future proof yourself where you can. Remember to book regular annual services for your boiler, and carry out any boiler repairs that may be needed before the problems build up.
Boiler installation cost
When looking for a new boiler, there are many different shops and websites where you can find and compare different models and choose which will be best for your home. Typically, when you purchase a boiler, you will also pay for an installation cost - unless you are a Gas Safe Register engineer, fitting it yourself is not a job you can legally do. However, in some circumstances you may want to purchase a boiler and hire an installer separately.
A gas engineer or qualified plumber will typically charge an hourly rate of around £60 to £100 depending on location and the time they are being called. It will usually take around half a day to a full day to install a boiler depending on its location in your home, so between £300 and £700 or so.
As with traditional gas boilers, installation costs for combi boilers will be based on the hourly rate of a qualified engineer. Hourly rates usually range from £60 to £100, so the overall labour cost of installing a boiler will be around £500.
How long does it take to install a boiler?
A straight replacement of an old combi boiler with a new combi boiler, in the same location, can be done in around four to six hours, a day’s work for an installer. These are the simplest and quickest jobs, so other scenarios can take longer to carry out.
For example, if you wish to carry out a power flush of the entire system, this can add a few hours onto the overall time. If you are moving the boiler to a new location, you can expect this to add half a day to the total job, so it may take place over two days. Similarly, if very outdated pipework that doesn’t meet current standards is found, it will take half a day for an installer to replace this.
If you are converting a regular system to a combi boiler, then you can expect this to take two days overall, as it will require removing the now-uneccesary water tank and rerouting pipework around your home.
