BEFORE YOU CALL

3 Safe Checks Before Calling an Emergency Boiler Engineer

Taking two minutes to check your system pressure, room thermostat, and fused power switch can sometimes get your heating back on immediately—or help us arrive with the exact replacement part.

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.

Note the fault code

Write down any fault code showing on the boiler display. This helps us understand the likely issue before attending.

Call us

Call 020 8051 2124 and tell us what has happened. We answer 24/7 and will advise you on the safest next step.

Repeated lockouts? Stop resetting your boiler

One reset might clear a temporary airlock, but constant lockouts point to an electrical, gas, or circulation component issue. If it trips repeatedly, call us to inspect it safely.

Frequently asked questions

Emergency boiler breakdown & out-of-hours callouts.

When your boiler fails in freezing weather or you lose hot water unexpectedly, speed and transparency matter. Here is what to expect regarding our rapid response windows, fixed transparent emergency rates (£180/£250), and immediate home safety steps.

Read our FAQs

We operate within a focused West and North West London patch (Ealing, Chiswick, Acton, Queen's Park, Kilburn, Wembley and Harrow), aiming for same-day attendance and providing you with a realistic arrival window when you call.

Our rates are transparently fixed before you commit: Emergency Weekday call-out (£180 first hour) and Emergency Out-of-Hours / Weekend / Night (£250 first hour). For non-urgent issues booked in advance, our standard weekday diagnostic is £120. The first hour covers callout and on-site diagnostic testing.

No. Resetting your boiler once or twice is fine, but repeated resetting when a lockout recurs can damage the ignition electrodes, PCB or fan, and risks flooding the combustion chamber with unburnt gas. If it locks out repeatedly, leave it turned off and call for an engineer.

If you smell gas, do not touch electrical switches or light naked flames. Open doors and windows, turn off the gas emergency control valve by the meter, and call the National Gas Emergency Service immediately on <strong>0800 111 999</strong> (free, 24/7). Once the supply is made safe, call us to repair the leak.

Yes. We coordinate directly with your tenant for urgent access, make the situation safe first, provide clear phone updates, and send a digital invoice and diagnostic report for your landlord records.
