About radiator replacement in Kensington
Kensington is a large city of around 156,000 in Greater London. The housing is mostly South West London housing leans Victorian and Edwardian with pockets of 1930s semis and modern flats. That matters: older properties usually mean more pipework, rewiring and retrofit surprises, while newer builds in districts like SW5, SW7, W8 tend to be quicker jobs with standardised fittings. Local trade prices sit on the expensive side for UK trade work. That's mostly wage levels plus the cost of running a van and a yard in and around Greater London.
London's the deepest trade market in the country, and also the priciest. ULEZ, congestion charge, parking permits, higher van insurance — it all feeds into the day rate. Most decent firms charge a callout and central boroughs run a clear premium over zones 4 and 5. Book two to three weeks ahead if you can.
Heating is a regulated trade. Gas Safe for anything gas, OFTEC for oil, HETAS for wood burners and stoves, MCS for heat pumps. The bulk of the price is the engineer's time, roughly £300 to £500 a day in 2025, plus the appliance. A summer quote on the same job is usually 10 to 15 percent less than a winter emergency one, so don't leave an ageing boiler until October.
