Frequently Asked Questions
How much does a one-off boiler repair cost?
If you need a one-off boiler repair, it costs £295 - you don’t even have to be a British Gas customer. For members it costs £280 and for members who have energy with us, it costs £265.
Parts and labour are included in your price no matter how long it takes. You also get a 12-month warranty.
If we can’t repair your boiler or separate work is needed, there’s a minimum £100 charge, You won't pay this if the repair is successful.
What kind of boiler repairs do you carry out?
We repaired around 1.3 million boilers in 2025 – and nobody knows boilers like a British Gas engineer. Whatever the problem and whatever the make and model, we can help to get things working again. Here are some of the most common reasons we’re called out:
- No hot water or heating in the home
- Boiler is showing an error code
- Strange noises from boiler
- Boiler doesn’t ignite
- Loss of boiler pressure
- Broken timers, controls or thermostats
- Leaking pipes or radiators
- Boiler won’t start
What should I do if I already have HomeCare?
If you already have HomeCare for your heating, you can go ahead and book your repair from your online account. You don’t need to choose the One-off Repair or Repair and Cover.
What happens if you can’t fix my boiler?
Our expert engineers can repair boilers of all ages, makes and models. But if we do find that your boiler can’t be fixed for some reason, we won’t charge you anything for the visit and we’ll give you a no-obligation quote for a replacement boiler.
What if I have more than one problem with my boiler?
The initial repair doesn’t include any unrelated faults. We’ll quote separately for other work needed for unrelated faults. This may happen if, for example, you’ve called us about a boiler breakdown but also ask us to fix a leaking radiator.
What if I want to cancel my initial boiler repair?
If we haven't started work on your boiler, you can contact us to cancel your repair. If you chose the Repair & Cover option, we'll also cancel your cover at the same time.
If we’ve already started the work, you may have to pay a cancellation charge for the work completed – see terms and conditions for details.
What if I want to cancel my ongoing boiler cover?
You can cancel your Central Heating Breakdown Cover at any time, whether during the 14-day cooling-off period or afterwards. However, if we've done any work for you then you'll have to pay cancellation charges.
What if I have more than one appliance/electrical problem that needs fixing?
Just choose one of the appliances you're having problems with and we'll chat about your other appliances/electrical issues when we speak over the phone.
