Boiler Repair FAQs
Everything you need to know about our boiler repair services in London, including costs, availability, and what to expect.
We offer same-day emergency boiler repair across London. In most cases, we can have a Gas Safe engineer at your door within a few hours of your call. Most repairs are completed in a single visit, typically taking 1–3 hours depending on the fault.

Yes. Our engineers carry the most common boiler parts on their vans, including thermostats, diverter valves, pressure relief valves, ignition electrodes, and more. This allows us to complete most repairs in a single visit without needing to order parts.
It depends on the age of the boiler and the cost of the repair. As a general rule, if your boiler is over 10–15 years old and the repair cost exceeds £500, it may be more cost-effective to replace it. Our engineer will give you honest advice on whether to repair or replace, with no pressure to buy a new boiler.
Boiler pressure loss is usually caused by a water leak somewhere in the system, a faulty pressure relief valve, or recently bled radiators. You can try re-pressurising via the filling loop, but if the pressure drops again, you need a professional to find and fix the leak. Call us and we will diagnose the root cause.
Yes. Every boiler repair we carry out comes with a 12-month parts and labour guarantee. If the same fault returns within that period, we will come back and fix it free of charge.
We repair all major boiler brands including Worcester Bosch, Vaillant, Baxi, Ideal, Viessmann, and Glow-worm. We also service gas, electric, oil, combi, system, regular, commercial, and LPG boilers.
