Boiler & Central Heating Plumbing
No heat and no hot water is usually one of four things: system pressure below roughly 1 bar, a failed diverter valve, a stuck pump, or a controls and thermostat fault. Pressure and controls can often be checked over the phone before anyone is booked.
A cold house in January is treated as urgent, particularly where there are young children, elderly residents or a vulnerable tenant. We take heating loss calls out of hours.
Plumbing and gas work are separate legal disciplines in the UK. Any work on gas appliances is carried out by Gas Safe registered engineers, and we hold public liability cover up to £5 million. The Gas Safe registration number is available on request.
