Simply answer a few multiple choice questions about your existing boiler and we’ll give you a fixed price for a new boiler including all parts and installation[28]

When someone needs a new boiler, one of the first questions they have is ‘How much will a new boiler cost?’ In the UK, when someone needs a new boiler it’s likely that they will choose a combination boiler, most commonly known as a combi boiler. Combi boilers produce heat and hot water from one combined compact system so they are great for saving space in your home.

The cost of the combi boiler itself will be much lower than the overall price given by an installer, usually because they’ve also included the cost of installation on top. Whilst the cost of installation may seem expensive, it’s important to note that a new boiler should always be installed by a gas safe registered engineer who will follow strict protocol checks and procedures. The additional cost of having a gas safe registered installer ensures peace of mind that the installation has been completed to the highest regulated standards.

There can be a substantial difference in boiler prices so if you want to know how much a combi boiler costs it’s best to get an online quote for your home. This will take into account your current central heating system, the boiler fuel type and how many radiators you have to give you an accurate price.

Our prices for a new combi boiler with installation start from £1899 [12] and we have a range of boiler brands and fuel types available. The price of a new combi boiler can depend on the brand you choose to have installed but it’s important to remember that you shouldn’t compromise on quality. If the price of a new boiler is particularly low, it’s worth checking to make sure the boiler itself is manufactured to a high standard to avoid additional repair costs at a later date.

We only install high quality boilers from reputable brands so you have the peace of mind that you’re getting the best for your budget. Our boilers come with a manufacturer backed warranty of up to 10 years [5] so you can be assured of how long lasting they are.
