Boiler repair in South London.Diagnosed and fixed today.
No heat, no hot water, pressure loss or an error code on the display — we diagnose the actual fault, quote a fixed price, and carry the common parts for Worcester Bosch, Vaillant, Ideal and Baxi on the van.
What is your boiler doing?
Pick the symptom closest to yours. You will see the usual causes, what we check on the visit and whether it is normally a same-day fix.
Is it worth fixing?
A rough steer before you call. Move the sliders and you will see what we would normally advise for a boiler in that condition — the visit itself gives you the real answer.
Diagnosis first, price second, repair third.
You are never asked to approve a figure before anyone has looked at the boiler, and the figure we agree is the figure on the invoice.
Describe the fault
Tell us the symptom and the error code if there is one. It often tells us which part to bring.
Full diagnosis on site
Gas pressure, flow and return temperatures, electrics and controls — not a reset and hope.
Fixed price to fix it
You get the cause, the part needed and a firm price before we touch anything.
Repaired and tested
We run the system up, check the flue and controls, and leave the work guaranteed for 12 months.
If a repair is not the answer.
Some boilers are past the point where another part makes sense. These are the other routes, and we will tell you honestly which one you are on.
Supply and fit of all major brands, sized for the property rather than swapped like for like. Manufacturer warranties of up to 10 years, registered for you on completion.
Most of the breakdowns we attend were preventable. An annual service keeps the manufacturer warranty valid and catches wear before it strands you in January. Landlord gas safety certificates can be done in the same visit.
When the boiler is fine but the house is cold, the fault is usually in the system: sludge, a seized pump, a failed diverter or radiators that were never balanced. That is heating work rather than a boiler repair.

Recent boiler and heating jobs across South London.
Used TopFix twice now, once for a boiler service and once for a radiator that was not heating. Both times on time, honest about the cost and the job done properly.
Clapham
Had a burst pipe on a Sunday evening and TopFix sent someone out within the hour. The plumber explained exactly what was wrong, fixed it cleanly and left everything tidy.
Sutton
Booked a full bathroom refit. The team was punctual and the price matched the quote exactly. Our older Victorian house had complicated pipework and they handled it without any fuss.

Boiler repair questions,

Call 020 3095 1113How much does a boiler repair cost?
It depends on the fault and the part. We diagnose first, then quote a fixed price for the repair before starting, so you can decide with the full picture. There is no call-out charge.
Can you come out the same day?
No heat and no hot water are treated as priority jobs, and we aim to attend the same day across South London. Less urgent faults are usually booked within a day or two.
Do you repair my brand of boiler?
We repair all major domestic brands, including Worcester Bosch, Vaillant, Ideal, Baxi, Glow-worm, Vokèra, Potterton, Alpha and Viessmann. Common parts for the brands we see most often in South London are carried on the van.
What if the boiler is beyond repair?
We will say so rather than selling you another part. You get the diagnosis, what a repair would cost and what a replacement would involve, and the decision is yours. Nothing is quoted on the spot under pressure.
Will the repair be guaranteed?
Yes. Repair labour carries a 12-month guarantee, and any parts we supply are covered by the manufacturer's own warranty.
Is my boiler still under warranty?
Most manufacturer warranties require an annual service to stay valid, and we check that before recommending chargeable work. If the boiler is still covered, we will tell you and point you to the manufacturer rather than invoicing you for something they should fix.
Cold house?
