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.

In Southall, a planning or building regulations application typically costs £1,000–£3,250 for application management (council fees extra), including VAT at 20% (standard rate; planning application fees carry no VAT, council building control fees include VAT).

Planning and building regulations in Southall
The approval route for Southall 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.
