About loft conversion in Woking
Woking is a medium town of around 103,000 in Surrey. The housing is mostly period cottages, Edwardian villas and 1930s semi-detached housing alongside newer commuter developments. That matters: older properties usually mean more pipework, rewiring and retrofit surprises, while newer builds in districts like GU21, GU22 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 Surrey.
A lot of South East firms work both London and local jobs. Rates usually track London with a small discount, so you're rarely getting a bargain. Peak season runs May to September and good tradespeople can be three to four weeks out. Out of season is the time to price round.
Building jobs are labour-heavy, and materials have moved fast — brick, timber, steel, insulation and board are all 20 to 40 percent up on pre-2022. FMB and TrustMark are your best signposts for a proper builder. On anything bigger than a loft conversion, get a Building Control officer involved from day one; fixing non-compliance later costs a fortune.
