/ Faults we fix every week
When a boiler stops, the first job is finding out why — properly, not by swapping parts until something works. Our engineers carry diagnostic equipment and the common spares for the major brands, so most repairs are completed on the first visit.
You get a clear explanation of the fault and a fixed price for the repair before any work starts. If the boiler is old and the repair isn't good value, we'll say so and give you a replacement quote to compare — the decision is yours.
We run a 24/7 emergency line for breakdowns and suspected gas leaks. If you smell gas, turn the supply off at the meter, open windows, don't operate switches, and call the National Gas Emergency number on 0800 111 999 first — then call us to make the appliance safe and get you running again.

/ Boiler repair cost in Reading
We diagnose first, then quote. The cost of a boiler repair depends on the fault and the part — a thermocouple or pressure relief valve is a very different job from a heat exchanger or PCB. You'll get a fixed price in writing before any work starts, and if a repair isn't good value on an older boiler we'll tell you and quote a replacement to compare.
/ Covering RG1 to RG6 and RG30/RG31 — the Oracle, the University of Reading, Caversham, Tilehurst and Woodley
Reading's Victorian terraces around the centre and the university are a big part of our work — narrow kitchens, boilers in bedrooms and loft conversions with awkward flue routes are all common. Further out in Tilehurst, Woodley and Earley the estates are mostly 1960s–80s semis reaching their second or third boiler. The town's water is hard and heat-exchanger scaling is a frequent repair call.
We cover the whole of Reading (RG1 to RG6 and RG30/RG31) — from the Oracle, the University of Reading, Caversham, Tilehurst and Woodley — and the surrounding areas including Caversham, Tilehurst, Woodley, Earley, Calcot, Theale, Twyford and Wokingham. Typical housing here is Victorian terraces in the centre, large inter-war and post-war estates, and new apartments around the station, and our engineers know the boiler types, flue positions and system layouts that go with it.
We're based in Woking, Surrey, roughly 30 minutes from Reading in typical traffic — a normal working day for us, not a special trip.
Same-day appointments are available for most of Reading, and every job — a service, a repair or a full installation — comes with a fixed price agreed before we start and a written record when we're done.

/ Questions we get asked
Straight answers. If yours isn't here, call — it's quicker than a form.
How quickly can you get to me?
Same day for most breakdowns in our coverage area, and we prioritise homes with no heating, no hot water, young children, elderly or vulnerable occupants. Call the emergency line and we'll give you an honest arrival window.
How much does a boiler repair cost?
It depends on the fault and the part. We diagnose first, then give you a fixed price in writing — you'll never get a surprise on the invoice. If the repair isn't worth doing on an older boiler, we'll tell you.
My boiler keeps losing pressure — is that serious?
It's usually a small leak somewhere in the system or a failed expansion vessel. Topping it up masks the problem and wastes inhibitor. Book a repair and we'll find the cause.
What does a boiler fault code mean?
Each manufacturer uses its own codes. Note the code and the boiler make and model when you call — it helps us bring the right parts.
Do you repair all boiler brands?
Yes — Worcester Bosch, Vaillant, Ideal, Baxi, Viessmann, Glow-worm, Potterton and others.
