What is a planning or building regulations application?

Planning permission decides whether a project can be built; building regulations decide how it must be built. Most extensions, lofts and conversions need building regulations approval even when planning permission is not required.

Planning and building regulations in Hailsham
Before anything is built in Hailsham, we confirm which approvals apply in England. In England householder applications, lawful development certificates and prior approvals for larger home extensions go to the local planning authority. Building control can be the council or a registered building control approver.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
Handled as part of most planning and building regulations applications:
- Discharge of planning conditions
- Planning or householder applications

- Building control application and inspections
How long does it take?
Allow about 8 weeks for a householder planning decision (two months in Scotland). If the drawings are for a planning application, add the council’s decision period once they are submitted.
