About decking installation in Slough
Slough is a large city of around 165,000 in Berkshire. 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 SL1, SL2, SL3 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 Berkshire.
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.
Landscaping prices move with materials. Natural stone, porcelain pavers and composite decking have all climbed sharply in the past two years. APL (Association of Professional Landscapers) is the trade body to look for. Retaining walls over a metre need Building Regulations, and raised decking over 30cm can need planning consent — worth checking before you start.
