Cost of Decking Installation in Sefton (2026)
Decking Installation in Sefton works out at £110 to £260 per m² in 2025, give or take.

About decking installation in Sefton
Sefton is a large city of around 276,000 in Merseyside. The housing is mostly red-brick Victorian terraces, stone-built millworker housing and post-war semi-detached estates typical of Northern industrial towns. That matters: older properties usually mean more pipework, rewiring and retrofit surprises, while newer builds in districts like L20, L21, L22 tend to be quicker jobs with standardised fittings. Local trade prices sit below the UK average. Lower contractor overheads and shorter distances across Merseyside do most of the work.
The North West swings hard on location. Manchester, Chester and Trafford are around the UK average; Blackburn, Burnley and Cumbria are well under it. Liverpool has no shortage of firms. If the job's in a Lake District postcode (CA, LA) expect a travel surcharge past the A590.
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.
