About decking installation in Dorchester
Dorchester is a market town of around 21,000 in Dorset. 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 DT1 tend to be quicker jobs with standardised fittings. Local trade prices sit in the same ballpark as the UK average, with Dorset firms quoting close to national rates.
Bristol and Bath run hot. Step outside them and into Devon, Cornwall or rural Somerset and the supply thins out fast, especially for specialist trades like heat pumps or unvented cylinders. Lead times get longer the further west you go, and most firms will add travel if you're past the nearest big town.
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.
