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 Watford
Before anything is built in Watford, 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.

Handled as part of most planning and building regulations applications:
- Prior approval (larger home extension) in England

- Build-over agreements with the water company
- Building control application and inspections

Questions about planning and building regulations applications in Watford
How much does a planning or building regulations application cost in Watford?
In Watford, a planning or building regulations application typically costs £750–£2,750 for application management (council fees extra), including VAT at 20% (standard rate; planning application fees carry no VAT, council building control fees include VAT). Your fixed price depends on the survey and drawings.
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.
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.
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.
