I need help replacing my existing shower kit.

Boiler Servicing & fix CH / thermostat Issue

£250

Creekmouth, Greater London

23rd Jul 2026

Primarily, the boiler needs serving. It's working and does the job but hasn't been serviced recently so needs doing. The mains water stopcock has developed a leak and that needs sorting and cleaning. Additionally, the radiators throughout the flat are sporadic and have a mind of their own, sometimes coming on when not needed and failing to come on when they are needed in spite of automatic timing controls on the boiler. This may be a thermostat control issue. Would like this diagnosed and fixed. Rads also need bleeding every now and then which I would like resolved.

I need someone to install a thermostat on the radiator tomorrow.
