A total boiler breakdown means no heat and no hot water. Our Gas Safe registered engineers respond to breakdowns across St Albans, aiming to reach you as quickly as we safely can and get your system running again.

Emergency Boiler Breakdown EXPERT
When a boiler breaks down completely, the priority is a fast, accurate diagnosis followed by a repair wherever possible on the same visit. Our engineers carry a wide range of common parts to avoid unnecessary return trips.
If the breakdown turns out to be the final straw for an old boiler, we can also talk you through boiler installation options so you’re not caught out again. Regular servicing is the best way to reduce the risk of a future breakdown.

Emergency Boiler Breakdown GUIDE
Boilers usually break down due to a failed component, low pressure, a tripped switch, ignition faults or a blocked condensate pipe (common in cold weather). Our engineers carry diagnostic equipment to identify the fault quickly rather than guessing.
If you smell gas at any point, this is not a boiler repair situation — turn off the gas supply if it’s safe to do so, don’t use switches or naked flames, and call the National Gas Emergency line on 0800 111 999, then see our Emergency Gas Leak Response page.

COMMON WARNING SIGNS
A boiler on the verge of breaking down often gives warning signs first — don’t wait until you have no heat at all.
No response at all is a classic sign of a full breakdown.
Needing to keep re-pressurising often points to a developing fault.
Could mean the boiler has stopped firing or circulating properly.
Often the clearest sign something has failed internally.
Should always be checked by an engineer as soon as possible.

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.
