Planning and building regulations in Mill Hill
Before anything is built in Mill Hill, we confirm which approvals apply 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 we handle
Handled as part of most planning and building regulations applications:
- Discharge of planning conditions

How long does it take?
Allow about 8 weeks for a householder planning decision (two months in Scotland). If the drawings are for a planning application, add the council’s decision period once they are submitted.
