Planning and approvals in Stowmarket
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.
In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
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).
Design and approval fees for Stowmarket
These are guide fees for Stowmarket, adjusted for East of England (×1.06) and including VAT. Council application and inspection fees are paid separately.

Local to Stowmarket
Our survey diary covers Stowmarket, including IP14. The same team covers Ipswich (11 miles), Bury St Edmunds (13 miles), Sudbury (15 miles), Woodbridge (17 miles), all within easy reach.
For homes towards Norfolk, Thetford is around 19 miles away. Across the East of England many houses sit on generous plots, and single-storey and wraparound extensions are a natural fit.
Included in a typical project
- Inspection bookings throughout the build
- Building regulations drawings and written specification
- Structural calculations for beams, lintels and foundations
- Energy and glazing checks, including whole-house calculations if needed
- Submission to the council or a registered building control approver
- Completion certificate on sign-off
Building regulations approval and planning permission are separate. A design can have planning consent and still need changes to meet the regulations, which is why we draw for both together.

Questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Stowmarket, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Stowmarket?
Yes. We cover Stowmarket and the surrounding parts of Suffolk. Site visits are free and there is no obligation.
How long does this take for a Stowmarket home?
2–5 weeks for drawings, depending on the council and the complexity of the project.
Who are building control?
Either your local council’s building control team or a registered building control approver. Both inspect the work and issue the completion certificate.
Full plans or building notice?
A full plans application gets the drawings checked before work starts, which we usually recommend for extensions. A building notice is quicker to submit but carries more risk if something needs changing on site.
