Boiler Repair in Farnborough
Gas Safe registered boiler repair and fault diagnosis on all major makes, from a local engineer based in Farnborough. Monday to Saturday, 8am to 5pm.
A boiler that has stopped is rarely a mystery once someone looks at it properly. The same handful of components account for most breakdowns in local homes, and the difference between a one-hour fix and a week without heating is usually diagnosis: reading the fault data, testing pressures and checking the controls before deciding anything needs buying.
This page is the starting point for boiler repair work across Farnborough and the towns around it. If the fault is urgent and you have no heat or hot water at all, the emergency boiler repair page covers breakdown call-outs. If water is escaping rather than the boiler failing, start with the emergency plumber page.
Common faults, and what causes them
Each fault below has its own diagnostic page on this site, written around the symptom, the likely causes and the checks an engineer makes. Read the one that matches yours before you call, or just ring and describe it.

Combi boilers
The bulk of local repair work. Diverter valves, plate heat exchangers, expansion vessels and pressure faults, on combis feeding a single bathroom or a whole family house.
System and heat-only boilers
Older setups with a cylinder, zone valves and a pump. Faults here are often outside the boiler itself, which is why we test the controls and valves rather than just reading the display.
Heating systems around the boiler
Sludge, seized pumps and blocked magnetic filters produce symptoms people blame on the boiler. Where a flush or a filter is the real answer, we say so instead of quoting parts.

Boiler repair questions
What does the repair visit actually involve?+
A short triage call first to get the make, the pressure reading and what the display shows. On site the fault is diagnosed properly against manufacturer data, then you get a written fixed price before anything is replaced.
Can you repair my make of boiler?+
We work on all the major UK makes, including Worcester Bosch, Vaillant, Baxi, Ideal, Glow-worm, Potterton, Alpha and Main. Common spares for the makes we see most often are carried on the van.
Repair or replace — how do you decide?+
A single failed component on a relatively young boiler is normally worth repairing. Once a boiler is well into its teens, or you have already paid for two repairs in quick succession, replacement usually makes better financial sense. You get the honest view on the day, not a sales pitch.
Do you repair boilers outside Farnborough?+
Yes. Farnborough is the base, and repair work runs across Aldershot, Fleet, Frimley, Camberley, Farnham, Yateley, Sandhurst, Woking and Guildford.
What if the fault is a gas safety issue rather than a breakdown?+
Gas work is only carried out by a Gas Safe registered engineer — our registration is 554328. If you can smell gas, leave the property and call the National Gas Emergency Service on 0800 111 999 before calling us.
When can you come out?+
Calls are answered Monday to Saturday, 8am to 5pm, and that is when repair visits happen. Ring and describe the fault and you will be told plainly what the next available slot looks like.
Tell us what the boiler is doing
Make, pressure reading, any code on the display — that is usually enough to point at the fault before anyone arrives.
