Single Storey Extension in Ellesmere Port works out at £1,620 to £2,880 per m² in 2025, give or take.

About single storey extension in Ellesmere Port
Ellesmere Port is a small town of around 55,000 in Cheshire. 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 CH65, CH66 tend to be quicker jobs with standardised fittings. Local trade prices sit below the UK average. Lower contractor overheads and shorter distances across Cheshire 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.
Building jobs are labour-heavy, and materials have moved fast — brick, timber, steel, insulation and board are all 20 to 40 percent up on pre-2022. FMB and TrustMark are your best signposts for a proper builder. On anything bigger than a loft conversion, get a Building Control officer involved from day one; fixing non-compliance later costs a fortune.
