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 Pinner
Approvals for a planning or building regulations application in Pinner follow the rules for 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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.

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.

The council can take enforcement action, and missing approvals cause problems when selling. It is always better to get approvals first.
