Builders in Cambridge
Phone numbers for builders covering Cambridge — extensions, loft conversions and refurbishment. Open a profile and call the business yourself. This site does not send your job.
Extensions and loft work need more than a day rate. The renovation budget tool can sit beside a local quote. Chesterton and Trumpington appear on Cambridge cards. A London day rate and a college contractor list are not the same document as a Romsey terrace quote. 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 for a sourced national range; a figure on a card is not a quote.
No businesses match those extra filters. Clear 24-hour or qualification to widen the list.
Typical building & conversions costs
Checkatrade’s house-extension guide, per-square-metre table last updated March 2025, is a national sense-check for shell versus finished work. It is not a local tariff. A loft over a Romsey terrace needs the alley for tiles and a party-wall conversation. College work needs the institution. Do not compare those prices with an Arbury extension that has a drive.
A local rule to check in Cambridge
Many extensions, loft conversions and structural openings need building control, and some need planning. A listing is not an approval and not a party-wall agreement.
Questions before you phone
How do I find builders in Cambridge on this list?
Romsey and Mill Road are Victorian terraces with a rear alley. Newnham and the college streets are a different client: the building may not be yours to alter. Arbury is later housing with a drive. Names, service areas and phone numbers sit on the cards. Open a profile and call the firm yourself. Chesterton and Trumpington appear on Cambridge cards. A London day rate and a college contractor list are not the same document as a Romsey terrace quote.
Does this page send my job to a Cambridge building & conversions firm?
No. You place the call. This site does not email or text anyone on your behalf.
What should the written price say for building & conversions in Cambridge?
Alley and party wall, institution, or a drive. Different clients.
What is easy to miss before booking in Cambridge?
Alleys behind Mill Road terraces are the access, and they are narrow. A permit for the front street does not move materials if the alley is where the boiler has to go.
