Builders in Oxford

Phone numbers for builders covering Oxford — 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. Botley and Kidlington appear on Oxford cards. A Reading firm is not local once the ring road is between the van and a Jericho street with nowhere to stop. 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.

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 rear extension in Jericho meets a party wall and a passage. Headington has side access. Ask for the one they have drawn, and whether a landlord's consent is the first document.

A local rule to check in Oxford

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 Oxford on this list?

Jericho is small Victorian houses hard against the canal. Headington and Cowley are later and higher. College-owned streets in the centre can require a landlord's contractor rather than the person you found on a list. Names, service areas and phone numbers sit on the cards. Open a profile and call the firm yourself. Botley and Kidlington appear on Oxford cards. A Reading firm is not local once the ring road is between the van and a Jericho street with nowhere to stop.

Does this page send my job to an Oxford 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 Oxford?

Passage and party wall, or side access. Landlord consent first if it is not your building.

What is easy to miss before booking in Oxford?

A college or a housing association may be the only party allowed to instruct the roof, the riser or the front door. Ask before you compare private-house prices.
