No heat or hot water is stressful, especially when it happens without warning. Our Gas Safe registered engineers diagnose and repair boiler faults across St Albans, aiming to reach you as quickly as we safely can and get your heating working again.

Emergency BOILER Repair EXPERT
From no heat and no hot water to strange noises, leaks or error codes on the display, a broken boiler needs a proper diagnosis, not guesswork. We aim to get to you quickly, identify the fault and repair it on the spot wherever possible so your home is warm again.
If we can’t fix it on the first visit, we’ll explain why and get any parts sourced as fast as we can. For ongoing peace of mind, our annual boiler servicing can help catch problems before they become emergencies, and a power flush can resolve recurring heating faults caused by sludge build-up.

Emergency BOILER Repair GUIDE
Not every boiler fault is an emergency, but some signs mean you shouldn’t wait: no heat or hot water, banging or gurgling noises, water leaking from the unit, a locked-out display or fault codes, or the pilot light going out repeatedly.
If you can smell gas, this is not a boiler repair situation — turn off the gas supply if it’s safe to do so, don’t use any switches or naked flames, and call the National Gas Emergency line on 0800 111 999 immediately, then see our Emergency Gas Leak Response page.

COMMON WARNING SIGNS
The same careful workmanship, whether it’s a family home in St Albans or a busy premises in Hertfordshire.
The most common emergency call — often fixable the same visit.
Banging, gurgling or whistling can signal a developing fault.
Water around the unit should be checked as soon as possible.
A locked-out display usually needs an engineer to reset safely.
Can point to a fault that needs proper diagnosis.
Not a repair job — see our Gas Leak Response page and call 0800 111 999.

ThanksPosted on Google Deepak M.BTrustindex verifies that the original source of the review is Google. I recently had my boiler serviced by Heatgap( 99 Byron Road,Luton) and I couldn’t be happier with the experience. The Technician arrived on time, was professional, and explained everything clearly. The service was thorough, and they made sure the boiler was running safely and efficiently before leaving. What really stood out was their friendly attitude and attention to detail. They took the time to answer my questions and gave helpful advice on maintaining the boiler. Overall, excellent service from start to finish. I would definitely recommend Heatgap to anyone looking for reliable and professional boiler servicing.
