About decking installation in Kingston upon Thames
Kingston upon Thames is a large city of around 177,000 in Greater London. The housing is mostly a mix of Victorian terraces, inter-war semi-detached housing and modern new-build estates. That matters: older properties usually mean more pipework, rewiring and retrofit surprises, while newer builds in districts like KT1, KT2 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.
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.
