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 Stevenage
The approval route for Stevenage 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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.

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.
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.
