Boiler repair in Wimbledon.Systems, cylinders and combis.

Same-day boiler repairs across SW19 and SW20. Larger Wimbledon homes run system boilers and cylinders, which fail differently from the combis in a flat — and get diagnosed differently too.

What fails here

The faults Wimbledon
keeps sending us.

Boiler faults follow the housing stock. These are the three we attend most often in Wimbledon, and the ones we arrive prepared for.

Motorised valve failureHeating on but no hot water, or the other way round. On a cylinder system that is almost always a valve head or actuator, and we carry the common ones.
Unvented cylinder faultsExpansion vessels, tundish discharge and thermostats. This work requires a G3 qualified engineer, which ours are.
Pressure loss on long runsLarge houses mean long circuits and more joints. We pressure-test to separate a genuine leak from a failed expansion vessel before lifting any floor.

Local knowledge

Why Wimbledon boilers
fail the way they do.

Arriving with the right parts starts with knowing what is likely to be on the wall before we get there.

Wimbledon has two distinct boiler populations. Around the Village, Copse Hill and the larger houses, system boilers with unvented cylinders are the norm, serving several bathrooms and long pipe runs. Through South Wimbledon and Raynes Park the terraces and conversions mostly run combis.

They break in different ways. Cylinder systems throw up motorised valve failures, immersion and thermostat faults and expansion vessel problems — heating and hot water behaving independently is the giveaway. Combis on long runs suffer pressure loss and diverter valve wear instead.

What a repair visit involves

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 one on the invoice.

Step 1

Describe the fault

Tell us the symptom and the error code if there is one. It often tells us which part to bring.

Step 2

Full diagnosis on site

Gas pressure, flow and return temperatures, electrics and controls — not a reset and hope.

Step 3

Fixed price to fix it

You get the cause, the part needed and a firm price before we touch anything.

Step 4

Repaired and tested

We test the system, check the flue and controls, and guarantee the labour for 12 months.

Recent boiler and heating jobs in Wimbledon and 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.

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.

JTJames T.

★★★★★

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.

Wimbledon questions

Before you book
a repair here.

Have the error code and the make of the boiler ready if you can. With those two things we can usually narrow it down on the phone.

Call 020 3095 1113
Do you work on unvented cylinders?

Yes — our engineers hold the G3 qualification that unvented hot water storage legally requires. Plenty of Wimbledon properties run them.

Heating works but there is no hot water. What is that?

On a system boiler it is usually a motorised valve, a cylinder thermostat or the coil. It is rarely the boiler itself, which is why diagnosis matters before anyone quotes.

Do you cover Raynes Park and the Village?

Both, along with Wimbledon Park, South Wimbledon and Merton Park — all of SW19 and SW20.
