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 Bristol
Before anything is built in Bristol, 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.
We check this for your address before design work starts, so there are no surprises later.
What we handle
On a typical planning or building regulations application we handle:
- Prior approval (larger home extension) in England
- Build-over agreements with the water company
- Planning or householder applications
- Permitted development assessment
- Building control application and inspections
- Party wall notices
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 Bristol
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.
Do I need a party wall agreement?
In England and Wales, if your work affects a shared wall, boundary or nearby foundations, notices must be served. Neighbours can consent or appoint surveyors.
Who carries out building control?
Either the council’s building control service or, in England and Wales, a private building control body registered to do the work. In Scotland and Northern Ireland building control is provided by the council.
