New boiler FAQ'S

View all →

Yes, in more ways than one.

First, we're a Which? Trusted Traders which means we have to work to their strict standards and guidelines.

Secondly, we're Gas Safe Registered, and so are all of the installers who fit for us.

We're also fully insured, giving you total peace of mind.

That's not a problem. If for whatever reason you change your mind, or need to cancel your install, you can do so without any fees.

If you have paid any monies via card, we will refund this directly back to your account.

All of our installation partners go through a lengthy and strict Which? Trusted onboarding process. They're fully insured, highly rated and carry a unique set of skills to get your job, done.

You'll receive details about your engineer prior to your install, including photo ID, so you know who to expect.

Our booking calendar is a live system which checks the real-time availability of engineers in your area, so it should be bang-on. On the rare occasion that the date has been double booked, or there's an error, we'll be in touch to arrange an alternative or discuss your options.

Generally, no. If your boiler is in a typical home with two floors, scaffolding won't be needed. If your flue is located above a conservatory or in a particularly high section of your roof, it'd be best if we check first. You can submit an eSurvey and upload some images for us to run through before you book.

We install a whole range of new boilers, from leading UK brands.

Our most popular being Worcester Bosch boilers, which come fully installed with up-to 10 year guarantee protection. Prices start from £2,195 (for a combi boiler installation).

Vaillant closely follows, with boilers like the ecoTEC Plus being our most popular premium offering.

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.

Simply put, after your new boiler has been installed, you don't need to do anything.

Our team will register your new boiler's warranty directly with the manufacturer and we'll also register it with Gas Safe so they're aware of the new appliance. The only thing you'll need to do is get your new boiler serviced annually (this is important to keep it running well, but, most importantly, to maintain it's warranty)

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

Learn more.

Yes, we can certainly try to.

For our new boiler installations, Blueflame 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.

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.

Buy Now Pay Later boiler finance is also available.

The cost of a new boiler depends on a variety of factors, including the type of boiler you select, your location and the complexity of your installation. But, the typical costs for installing a boiler are:

Combi boiler replacement: £1,800 - £2,800

Regular boiler replacement: £2,000 - £2,800

System boiler replacement: £2,000 - £2,800

Conversion (regular to combi): £2,600 - £3,500

This largely depends on the efficiency of your current boiler and how much energy you use. For example, you could save as much as £840 per year if you are upgrading from an old G-rated boiler to a modern A-rated boiler (along with a programmer, room thermostat and thermostatic radiator controls (TRV's)).
