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 Carlisle
Approvals for a planning or building regulations application in Carlisle 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.
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.
We check this for your address before design work starts, so there are no surprises later.

Questions about planning and building regulations applications in Carlisle
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.
How much does a planning or building regulations application cost in Carlisle?
In Carlisle, a planning or building regulations application typically costs £750–£2,250 for application management (council fees extra), including VAT at 20% (standard rate; planning application fees carry no VAT, council building control fees include VAT). Your fixed price depends on the survey and drawings.
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.
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.
