Do not remove the boiler casing or attempt gas-related repairs yourself. These checks are only to help us understand the issue before attending.

Check the pressure
Look at the boiler pressure gauge. If it is below 1 bar or much higher than normal, tell us when you call.
02
Note the fault code
Write down any fault code showing on the boiler display. This helps us understand the likely issue before attending.
03

When it can't wait until tomorrow
Cold rooms and no hot water are calls we drop everything for — especially with young children, elderly or vulnerable people at home.
No heating
Radiators cold and the house freezing? We trace the fault — pump, valve, PCB or sensor — and get the heat back on.
No hot water
Cold taps and no shower? We diagnose diverter valves, diaphragms and heat exchangers and put hot water right.
Leaking boiler
Water pooling under or around the boiler is made safe first, then we trace the leaking seal, valve, pipework or fitting before it spreads.
Fault codes & lockouts
A boiler locked out on a fault code is checked safely, with the underlying cause found and fixed — not just reset and ignored.
Pressure problems
Pressure that keeps dropping or climbing is investigated properly — including the expansion vessel, PRV and possible hidden leaks.
Ignition & flame faults
A boiler that will not fire, keeps clicking, locks out or shows a flame fault is diagnosed safely and repaired where possible.

Emergency boiler repair FAQs
Clear answers for homeowners, landlords and tenants dealing with urgent boiler problems across West and North West London.
Ask on WhatsAppWhat should I do if my boiler has stopped working?
Check the boiler pressure gauge, thermostat, programmer and fuse spur if it is safe to do so. Note any fault code on the display and call us with the details. Do not remove the boiler casing or attempt gas-related repairs yourself.
How quickly can you get to me?
We prioritise no-heating, no-hot-water and unsafe boiler faults across West and North West London. Call us and we’ll give you an honest arrival time before you commit.
Can you repair my boiler the same day?
In many cases, yes. Our engineers carry common parts for popular boiler brands, so some faults can be repaired in a single visit. If a part needs ordering, we’ll explain the issue clearly and make the boiler safe where possible.
What should I do if I smell gas?
If you smell gas or suspect carbon monoxide, call the National Gas Emergency Service immediately on 0800 111 999. Open doors and windows if safe, do not turn electrical switches on or off, avoid flames, and leave the property if advised.
Is it safe to keep resetting my boiler?
No. One reset may clear a temporary fault, but repeated lockouts usually mean there is an underlying issue. If your boiler keeps needing to be reset, stop resetting it and book a Gas Safe engineer to diagnose the fault safely.
What should I do if my boiler is leaking?
Turn the boiler off if it is safe, avoid touching electrics near the leak and call us for advice. A leaking boiler may be caused by pressure issues, failed seals, valves, pipework or internal components and should be checked by a qualified engineer.
