What fails here

The faults Sutton
keeps sending us.

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

Frozen condensateIn a Sutton winter this is our most common single callout. The pipe is thawed, the boiler restarted and the run re-lagged or rerouted so it does not happen again in January.
Kettling and scaleHard water leaves scale on the heat exchanger and the boiler starts to sound like a kettle. We assess whether descaling is worthwhile or whether the exchanger is past it.
Baxi and Ideal faultsThe two brands we see most in SM postcodes. Diverter valves, fans and PCBs for both are carried on the van, so most Sutton repairs finish in one visit.

Local knowledge

Why Sutton 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.

A large share of Sutton's boilers sit in 1930s semis and post-war houses where the appliance has been replaced once, sometimes twice, but the system around it never has. Baxi and Ideal dominate, often at twelve to eighteen years old, and many have gone several years between services.

The result is predictable. Scaled heat exchangers from the hard water, sludge from systems that were never dosed with inhibitor, and condensate pipes run outside along north-facing walls that freeze in the first cold snap and lock the boiler out.

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.

Words from our customers

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.

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.

Sutton 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
Can you get to me today?

No heat and no hot water are priority jobs and we usually reach SM1 to SM3 the same day. Ring early if you can — mornings give us the most room to fit you in.

My boiler locked out overnight. Is it the pipe?

Very likely, if it happened in cold weather. A frozen condensate is the classic Sutton winter fault and it is one of the cheapest things we deal with.

Is my boiler too old to bother repairing?

Not automatically. Fifteen years with one fault is usually worth fixing; fifteen years with three faults in two winters is usually not. We diagnose first and tell you which one you have.
