Do I need planning permission in Edmonton?
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
The planning position for a specific Edmonton address depends on its history and any designations, which is why we check it at the first visit.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).

Covering Edmonton
We cover Edmonton and the postcode districts EN1, N9, N13, N17, N18, N21. We also work in nearby Ponders End (1 mile), Tottenham (2 miles), Enfield (2 miles), Palmers Green (2 miles).
Just over the Essex border, Waltham Abbey is about 5 miles away. Across London, terraced houses with narrow side returns and tight access are the norm, which shapes everything from party wall notices to how materials reach the back garden.
Included in a typical project
- Building regulations drawings and written specification
- Completion certificate on sign-off
- Energy and glazing checks, including whole-house calculations if needed
- Submission to the council or a registered building control approver

Build and sign-off

Common questions in Edmonton
Do I need building regulations approval in Edmonton?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How long does this take for a Edmonton home?
2–5 weeks for drawings, depending on the council and the complexity of the project.
Who do I contract with in Edmonton?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
What are the insulation standards for an extension?
In England, new walls in an extension should achieve a U-value of 0.18 W/m²K, roofs 0.15 and floors 0.18, with windows at 1.4 and rooflights at 2.2. Wales, Scotland and Northern Ireland set their own figures.
