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 Winchester
Whether you need planning permission depends on your house and its location 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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
