My boiler keeps losing pressure — is this an emergency? +
A boiler that loses pressure gradually over weeks usually has a small leak somewhere in the system — often a radiator valve or a pipe joint. This is not an immediate emergency but needs investigating. If the pressure drops rapidly or the boiler is cutting out repeatedly, call an engineer promptly. You can repressurise the boiler using the filling loop as a temporary fix, but this does not solve the underlying problem.
How long does a boiler service take? +
A standard annual boiler service takes 30 to 45 minutes. The engineer will inspect the boiler internals, check gas pressure and flow rate, carry out a flue gas analysis, and test all safety devices. You will receive a service record which you should keep as proof for your warranty. The engineer should also flag any parts showing early signs of wear.
How do I know if my boiler needs replacing rather than repairing? +
If your boiler is over 10 to 15 years old, breaks down frequently, or has an efficiency rating below A (90%+), replacement is usually more cost-effective than repeated repairs. A single repair costing over £400 on an older boiler is often not worthwhile. Modern condensing boilers are up to 30% more efficient than older models, so a new boiler can pay for itself through lower gas bills within 5 to 7 years.
What should I do if I smell gas near my boiler? +
If you smell gas, do not touch any electrical switches, do not light any flames, and open all windows and doors immediately. Turn off the gas supply at the meter using the emergency control valve — turn the handle so it sits across the pipe. Leave the property and call the National Gas Emergency Service on 0800 111 999 from outside. Do not re-enter until given the all-clear.
Which boiler brands do your engineers in Liverpool work on? +
Our boiler engineers in Liverpool work on all major brands including Worcester Bosch, Vaillant, Baxi, Ideal, Viessmann, Glow-worm, and Potterton.

If you have a less common boiler brand, let us know and we will match you with an engineer who has experience with your specific model.
Is a leaking boiler dangerous? +
A leaking boiler should always be taken seriously. While a small drip from a pressure relief valve may indicate a minor issue, water leaking from the boiler casing can damage internal electrics and create a safety hazard. Never attempt to repair a boiler leak yourself.
