FAQs

Frequently asked questions

Not sure whether to repair or replace? Learn more.

How much does a new boiler cost in Nottingham?

A standard combi swap is £1,800 to £2,500, starting at £1,765 for a straight like for like. A full system conversion, like taking out a back boiler, is £2,500 to £3,500. Free survey and a written quote, or from £21/month on finance.

How long does a boiler installation take in Nottingham?

Most are done in a day. Back boiler conversions and jobs where the boiler moves rooms take two to three. You'll know which before we start, not on the day.

Do you cover my part of Nottingham?

Yes, every NG postcode. West Bridgford, Wollaton, Arnold, Bulwell, Clifton, Beeston, Long Eaton, Hucknall and out to Bingham. We're 35 minutes away in Alfreton and in the city every week.

Can you replace a back boiler in a Nottingham terrace?

Yes, we do a lot of these in Sneinton, Lenton, Forest Fields and the Meadows. It's a bigger job than a swap because the pipework and flue change, and it's usually two days. It's also the biggest efficiency jump an older house can get.

Do I need a combi or a system boiler?

One bathroom, a combi. Two or more and a busy household, a system boiler with a cylinder. It's the question we get most in West Bridgford and Wollaton where the houses are bigger. The survey settles it in ten minutes.

Are you Gas Safe registered?

Yes. All our engineers are Gas Safe registered, number 617191, and you can check that on the Gas Safe Register. We're also Baxi Approved Installers and Worcester Bosch accredited, which is how we can offer up to 12 years warranty.

Which boiler brands do you install?

Baxi, Worcester Bosch, Vaillant and Ideal. We'll recommend the one that suits your house, not the one with the best margin, and we'll explain why.

Do you offer finance?

Yes, through Phoenix Financial Consultants, who are FCA regulated. Spread it over 1 to 10 years, with 0% APR options and a buy now pay later option. KAS Energy Ltd is not a financial adviser. Subject to status.

Should I repair or replace my boiler?

Under ten years old with a sensible repair bill, repair it. Over ten to fifteen, breaking down more than once a year, or eating gas, replace it. We'll tell you straight either way, even when the answer costs us the job. Read our repair or replace guide.

Do you charge extra for travelling to Nottingham?

No. The quote is the quote, wherever you are in the city.

How much should a new boiler installation cost?

For a like for like combi swap in Nottingham, £1,800 to £2,500. Directories put the national average around £2,400, so a local installer usually comes in under it. What pushes a price up is moving the boiler, changing the flue, or converting from one system type to another.

Can you legally install your own boiler?

No. A gas boiler has to be installed by a Gas Safe registered engineer. Without a Gas Safe certificate your home insurance can refuse a claim and the manufacturer warranty won't stand. Our registration is 617191.

Do you need access to all radiators when fitting a new boiler?

Usually yes, for a short while. We flush the system and balance every radiator so the new boiler runs properly. If there's a room we can't get into, tell us at the survey and we'll plan around it.

Do I qualify for a free boiler in Nottingham?

Some households on certain benefits qualify for a free or subsidised boiler through the government's ECO4 scheme. We're not an ECO4 installer, so we'll tell you honestly if you might be eligible and point you at the scheme. If you're not, finance from £21/month is usually the better route.
