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 March?
In March, 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).

Planning and building regulations in March
Here is how the rules work for a planning or building regulations application 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.

Questions about planning and building regulations applications in March
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.
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.
Do you handle planning and building regulations applications in March?
Yes. We handle planning and building regulations applications across March, including postcodes PE15. Every project starts with a free home visit.
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.
