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.
How much does a planning or building regulations application cost in Seaford?
In Seaford, 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). We start from a UK-wide guide and adjust it for the South East, where labour and materials are typically about 12% above average. Council application fees are extra.

Planning and building regulations in Seaford
The approval route for Seaford is set by planning law 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
What we handle
From survey to sign-off, the job normally involves:
- Discharge of planning conditions
- Build-over agreements with the water company
- Prior approval (larger home extension) in England
- 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 Seaford
How much does a planning or building regulations application cost in Seaford?
In Seaford, 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.
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.
Do you handle planning and building regulations applications in Seaford?
Yes. We handle planning and building regulations applications across Seaford, including postcodes BN25. Every project starts with a free home visit.
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.
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.
