Here to help you

Boiler issues can arise from various causes, from air in your system to limescale buildup, to failed components and valves, and even incorrect control settings. Many problems can be fixed relatively quickly and easily, but if left unaddressed, can often escalate into serious problems that can cause the boiler to shut down and necessitate expensive repairs.

If you’ve noticed anything unusual about your boiler, don’t ignore it: get in touch with an experienced heating engineer today to resolve the issue. It may be nothing, but you may also save yourself hundreds of pounds and severe inconvenience by fixing a minor problem before it escalates.

Frequently asked questions

What types of boilers can you repair?

Our team is qualified to work on all makes and models of domestic gas boilers.

Do you do emergency callouts/when can you get to me?

Yes. While our engineers are very busy, we aim to get to you as quickly as possible, and will treat shutdowns and boiler failures as urgent repairs. Please call us as soon as possible to discuss when we can get out to you.

How much will a callout cost me?

We can typically diagnose most boiler issues within an hour, which will cost £87.50 + VAT. A lot of common errors can be fixed while we are there and some don’t need parts. If parts or a return visit is required, further charges will be discussed with you on site before work begins.

How much will it cost to fix my boiler?

This depends if parts are needed and if so, which parts. Minor issues, such as thermostat problems, leaks, or minor electrical issues may be fixable without parts. Some repairs may be covered by your manufacturer if your boiler is under warranty. Get an instant quote

Do you do same day repairs?
Whenever possible, yes. However, our ability to fix the same day depends on the availability of parts. We do keep a stock of common parts, but if the part you need isn’t available, we can get them ordered and aim to get back to you as quickly as possible.

Came out to fix a problem on the day we asked if they were available, and actually explained and solved the problem required, for a reasonable price. Breath of fresh air after an awful experience with a previous company who clearly couldn’t care less and quoted stupidly inflated prices. So so happy with Eric’s work, thank you.
