How to read a price for extensions, loft conversions and refurbishment

The Checkatrade house extension cost guide, table last updated June 2026, puts a finished extension at £1,800–£3,000 a square metre excluding VAT, average £2,400. A shell only is £1,200–£1,700 a square metre, average £1,450, also excluding VAT. Brick terraces run across Manchester and into Salford, Stockport and Oldham. A tight flue, a shared alley or a rear roof that needs scaffold is a different job from a house on an open street. The guide does not publish a Manchester total. A rear extension on a brick terrace needs the access described. Warrington is not on this list. A figure here is not a quote from this site. Checked 14 October 2026.
