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 Haywards Heath
Before anything is built in Haywards Heath, 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.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
What we handle
From survey to sign-off, the job normally involves:
- Discharge of planning conditions
- Party wall notices
- Lawful development certificate applications
- Planning or householder applications
- Permitted development assessment
- Prior approval (larger home extension) in England
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.
