Doherty's Gas carries out central-heating installation and repair across North London — including radiator replacement, pump and valve repair, system upgrades, and balancing for systems with uneven heat distribution. In older properties, we also assess and address issues such as sludge build-up and airlocking that reduce efficiency over time. Central-heating work in converted flats and managed properties requires coordination around shared pipework and building access, and we factor these requirements into every job plan. All work is fully insured.
