Chelsea is a small town of around 61,000 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 SW3, SW10 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.
