How much does it cost to buy or repair a boiler?
The new boiler costs and boiler repair costs in this article are correct as of 2019
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 cost of new gas boilers, including combi boiler costs, so you know what to expect before you make the leap.
Types of boiler
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.
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 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.

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.
New boiler costs
The prices of boilers will vary on a number of factors, depending on the brand, the size, and it’s energy efficiency. The following price breakdowns show some of the typical new boiler costs.
Combi boiler costs
Combi boilers 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 straight replacement of the boiler - 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.
Traditional gas boiler costs
The average price of a traditional boiler, including installation, is around £1,500 to £1,800. 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.

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.
Boiler installation costs
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.
MyBuilder Top Tip
You should only ever hire a Gas Safe registered engineer to carry out boiler work in your home. Anyone working on an appliance connected to a gas supply who is not registered with the scheme, formerly CORGI, is breaking the law. Ask to see a tradesperson’s Gas Safe card and check their number with the Gas Safe database.
Boiler service costs
If you want your boiler to last as long as possible, it’s vital that you schedule regular services to make sure it’s all in working order. Annual services should ensure that everything is running as it should be.
A traditional boiler inspection cost will usually be around £75 to £100, with larger, national firms often charging more. It shouldn’t take long to carry out as long as there are no underlying problems that need addressing.
Although combi boilers can cost more than gas boilers to purchase up front, servicing is usually priced very similarly. An inspection will usually cost around £75 to £100, though larger firms can charge more than independent tradespeople. As ever, make sure your tradesperson is on the Gas Safe Register.

Many people only think about their boilers when cold weather sets in and then have to fire the heating up. Don’t leave it too late though - as the dead of winter is the last time you want to find out your boiler does have a problem. Gas engineers will typically have lighter schedules in the summer as they deal with fewer emergency calls, so get it booked during warmer months to have peace of mind all year round.
