/ 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 Winchester
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 SO21, SO22 and SO23 — the Cathedral, the High Street, Weeke, Badger Farm and Kings Worthy
Winchester's centre is full of period and listed buildings where flue positions, pipe routes and boiler locations need thought and sometimes consent — we're used to working with those constraints. Out at Weeke, Stanmore and Badger Farm the estates are more conventional, and Barton Farm brings a lot of new-build boilers into their first service cycle.
We cover the whole of Winchester (SO21, SO22 and SO23) — from the Cathedral, the High Street, Weeke, Badger Farm and Kings Worthy — and the surrounding areas including Kings Worthy, Alresford, Twyford, Otterbourne, Colden Common, Sutton Scotney, Bishops Waltham and Micheldever. Typical housing here is listed and period properties in the centre, post-war estates at Weeke and Stanmore, and new housing at Barton Farm, and our engineers know the boiler types, flue positions and system layouts that go with it.
We're based in Woking, Surrey, roughly 45 minutes from Winchester in typical traffic — a normal working day for us, not a special trip.
Same-day appointments are available for most of Winchester, 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.
