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 Hadleigh
Here is how the rules work for a planning or building regulations application 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.
We check this for your address before design work starts, so there are no surprises later.
What we handle
From survey to sign-off, the job normally involves:
- Discharge of planning conditions
- Lawful development certificate applications
- Permitted development assessment
- Build-over agreements with the water company
- Party wall notices
- Planning or householder applications
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.

Questions about planning and building regulations applications in Hadleigh
What is a lawful development certificate?
A certificate from the council confirming that a project is permitted development. It is optional but useful when selling the house.
What is the difference between planning permission and building regulations?
Planning permission controls what you build and how it looks and affects neighbours. Building regulations control how it is built: structure, fire safety, insulation and drainage.
What happens if I build without approval?
The council can take enforcement action, and missing approvals cause problems when selling. It is always better to get approvals first.
