Builders in Birmingham
Phone numbers for builders in Birmingham — extensions, loft conversions and refurbishment. Birmingham and Sutton Coldfield, not Solihull. Open a profile and phone the business yourself. This site does not send the job.
An extension or a loft is more than a day rate. Ask what the written package includes. This list is Birmingham and Sutton Coldfield. Solihull, Wolverhampton, Dudley, Walsall and Coventry are not added to a Birmingham card. Profiles show a name, the area they cover and a phone number. Public qualifications such as Gas Safe or NICEIC appear only when they are on the profile. Read the cost notes before you treat a number as the price. A figure on a card is not a quote from this site.

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. Terraces and inter-war houses sit inside Birmingham and Sutton Coldfield. Solihull, Wolverhampton and Dudley are not on this list, so do not price a Black Country job from a Birmingham card. The guide does not publish a Birmingham total. An inter-war plot and a tight terrace plot do not share the same access, even at the same £1,800–£3,000 a square metre. A figure here is not a quote from this site. Checked 14 October 2026.
What to check in Birmingham
Many extensions, loft conversions and structural openings need building control, and some need planning consent. A listing is not that consent and it is not a party-wall award. Terraces and inter-war houses sit inside Birmingham and Sutton Coldfield. Solihull, Wolverhampton and Dudley are not on this list, so do not price a Black Country job from a Birmingham card. Then ask whether the pound-per-square-metre figure excludes VAT, and what finish it stops at.
