Will the council need to approve it?
In England a wraparound extension is assessed as both a side and a rear extension, and the combination usually falls outside permitted development, so most need a householder planning application (£548 from 1 April 2026).
The planning position for a specific Bedford address depends on its history and any designations, which is why we check it at the first visit.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
Covering Bedford
Site visits are available across Bedford (MK40, MK41, MK42, MK43, MK44). Neighbouring towns we cover include Kempston (2 miles), Ampthill (8 miles), Leighton Buzzard (17 miles), Dunstable (17 miles).
The East of England mixes market-town terraces, inter-war semis and modern estates. Clay soils are common in parts of the region, which can affect foundation design.

Common questions in Bedford
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Bedford, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
How long does a wraparound extension take to build in Bedford?
On site, typically 14 to 20 weeks once approvals are in place. Before that, allow 8–16 weeks design and approvals.
Do you cover all of Bedford?
Yes. We cover Bedford and the surrounding parts of Bedfordshire. Site visits are free and there is no obligation.
How much does a wraparound extension cost?
Our guide range is about £2,120 to £3,920 per m² including VAT. A 25 m² standard-spec wraparound typically lands around £60,500 to £77,000 in Bedford before design and council fees.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
