About decking installation in Northampton
Northampton is a large city of around 224,000 in Northamptonshire. 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 NN1, NN2, NN3 tend to be quicker jobs with standardised fittings. Local trade prices sit in the same ballpark as the UK average, with Northamptonshire firms quoting close to national rates.
East Midlands pricing sits a touch below the national average. Nottingham, Derby and Leicester are the higher end; smaller towns are noticeably cheaper. Plenty of Travis Perkins, Selco and Howdens branches across the region means parts rarely hold a job up.
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.
