Explore our range of premium boiler brands.
Combi boiler prices
Combi boilers provide heat and hot water from a single unit, so there's no need for an extra cylinder. They're the most popular type of boiler in the UK.
System boiler prices
More common in slightly newer homes or heating systems. Unlike combi boilers, they require a separate pressurised cylinder to provide hot water.
Heat only boiler prices
Also known as regular boilers, they require two separate tanks to operate (a storage tank in the loft, and a separate cylinder). Better for larger homes with high demand.

Everything you need to know
It depends on the type of boiler installation which you're getting.
On a new combi boiler installation, as standard, you'll get the boiler, all required flue accessories, a system flush, new Boiler Plus compliant controls, a magnetic boiler filter and any extras, such as a gas pipe upgrades and/or condensate pipe upgrades.
On a new regular/system boiler installation, as above, you'll get the boiler, flue accessories, flush, a magnetic boiler filter, gas and condense upgrades and we'll reconnect to your existing boiler controls and cylinder.
We also offer upgrades, such as smart thermostats to remotely control your new boiler, improved flushing options and more.
On average installing a new boiler takes between 1 to 2 days to complete.
If you are having your old boiler replaced in the same location and with the same type of boiler the process will be quicker (likely one day) compared to installing a different type of boiler in a new location.
So, to summarise:
Straight forward boiler replacement:
Takes 1 day
A boiler replacement, including a relocation:
Takes 1-2 days
A conversion from a regular to a combi:
Takes 1-2 days
Yes, we can certainly try to.
For our new boiler installations, Heatable works with a panel of lenders when offering boiler finance, so, if for whatever reason you didn't pass with our primary lender, we will pass it over to a secondary who will be able to assist.
Failing that, we have a range of other payment options available such as payment via credit card, Klarna, and more.
First, you'll go through some online questions to ascertain what type of boiler installation you require, and match you to suitable products.
Next, you'll choose a new boiler which suits your budget (prices start from £1,795).
Then, you'll choose whether to spread the cost of your new boiler with finance or pay using your card.
Once you've booked, you'll upload some images of your existing setup to make sure we order the correct materials, and to avoid delays on the day of your installation.
Once installed, we'll register your new boiler's warranty and sort all of the paperwork.
At the last step of booking your installation, you’ll see a “Discount code” box.
Simply fill it out, submit, and if it is valid it’ll auto apply to your order.
Only 1 code is allowed per order.
Yes, it’ll be removed from site and recycled.
Yes, as long as the quote which you have is comparable, like-for-like and from a reputable installer.
If you send the quote to [email protected], we’ll take a look at it and see what we can do.
On our standard installation packages, no, servicing is not included.
We can certainly help with servicing, but it would be at a cost of around £99. It needs to be done annually, and any heating engineer can do this for you.
We calculate the required size based on your form data.
If you wish to get a more powerful one, you can select the boiler and select the bigger size from the options. It’ll show what’s available, and the costs.
Yes, you can. All of our installations have finance options available.
You can spread the cost over 3, 5, or 10 years at a rate of 9.9% APR. Or, you can spread the cost with 0% APR up-to 4 years on certain packages.
