Boiler Service

A boiler service is a safety and maintenance visit, not a repair with a new part already assumed. MTEX Services services domestic gas boilers across Sutton, Carshalton, Wallington and the nearby districts. The published price starts from £80 plus VAT. Gas work is carried out under Gas Safe registration 618835.

Sutton’s postcodes are SM1 for the town centre, SM2 for Belmont and south Sutton, and SM3 for Cheam. Carshalton is SM5. Wallington, Beddington and Hackbridge are SM6. The houses are not the same, and neither are the boilers. A combination boiler in a cupboard in a Sutton flat, a system boiler in a 1930s semi, and an older heat-only boiler with a cylinder in a larger Cheam or Woodcote house all need the same safety checks, but the faults we find are different.

On a service we look at the flue and the ventilation, the safety devices, the burner and the condensate, and we check for leaks, scale and anything that is likely to fail next. Hard water in this part of south London coats the plate that heats the hot water on a combi, and the coil in a cylinder. A noisy boiler, a shower that has slowed down, and radiators that need bleeding every week are the usual clues. A service will not deep-clean a system that has been neglected for years. It will show whether the boiler is safe to leave running, and whether scale or sludge is the next problem.

Condensate pipes on combis in flats and terraces are often run outside. In a cold snap they freeze and the boiler locks out. That is a repair, not something an annual service can prevent if the pipe is still outside and unlagged. If we see that on a service, we say so.

If a part is needed, we tell you before fitting it. If the boiler is not worth repairing, we say that too, and we can quote for a boiler installation. A new gas boiler is not paid for by the Boiler Upgrade Scheme. That grant is for heat pumps. The detail is on the Boiler Upgrade Scheme page.

A service is also not the same document as a landlord gas safety certificate. Landlords need the safety record every 12 months. A service is the maintenance visit. They can be done on the same day if you want both, and we will say what each one covers.

Booked services are Monday to Friday, 8am to 6pm, and Saturday, 9am to 1pm. If the boiler has shut down and you have no heating, use the emergency call-out. If you smell gas, leave the house and call the National Gas Emergency Service on 0800 111 999 before you call an engineer. Do not keep resetting a boiler that is trying to turn itself off.

We work in the London Borough of Sutton and the other south London places listed on areas we cover, including Croydon, Mitcham and Morden, and in nearby Surrey towns such as Banstead, Epsom and Ewell. Sutton and Carshalton are in London, not in the county of Surrey.
