Enfield validation checklist and building regulations drawings

A validation checklist is the list of documents Enfield needs before it registers a planning application, and it is separate from building regulations drawings. We prepare the building regulations drawings from £745, and the authority has five weeks from receipt to notify its outcome on a full plans application.

Two submissions, two checklists

Planning validation asks whether the application is complete: plans, forms, fee and any documents the council's local list requires. Building Regulations ask whether the work will comply once built. Passing the first says nothing about the second.

Check Enfield's own current validation list on its website before you submit a planning application, as councils revise them. For the planning stage, our planning permission service covers the drawings. This page is about what comes after: the construction set Building Control reads.

What Building Control needs from a full plans package

Expect sections through the floor, wall and roof, beam and foundation positions, drainage, the escape route and a specification. Our building regulations approval guide explains what triggers approval, and planning drawings against building regulations drawings shows what changes between the two sets.

Structural calculations are a separate piece. Our structural drawings service covers the beams and openings that the construction set refers to.

Of 267 householder appeals decided between 2021 and 2026, 40% were allowed (our analysis of the Planning Inspectorate Casework Database, release 2609); that is a past record, not a forecast.

Clocks that start once you submit

The authority must notify the outcome of a full plans application within five weeks of receipt, or a longer period agreed in writing (Building Regulations 2010, regulation 14A(6)). A separate rule governs the start: once the notice of intention to start is given, at least two days must pass, counted from the end of that day, before work begins (regulation 16(1)(b)).

Both are in the regulations on legislation.gov.uk.

Enfield in the figures

On the planning side, 83% of Enfield's 934 householder decisions between 2025 Q3 and 2026 Q2 were grants, prior approvals included, and 92% of the decisions that were not prior approvals came within 8 weeks (our analysis of MHCLG planning application statistics, table PS2).

Of 267 householder appeals decided between 2021 and 2026, 40% were allowed (our analysis of the Planning Inspectorate Casework Database, release 2609); that is a past record, not a forecast. The national register lists 24 conservation-area entries for Enfield (our analysis of the MHCLG Planning Data Platform conservation-area dataset, snapshot retrieved 14 Aug 2026), so check the council's conservation area map for your address.

FAQ

Questions people ask

Is the validation checklist the same as the building regulations checklist?
No. Validation is part of the planning application. The building regulations application is made separately, to Building Control.
Does an Enfield extension need both?
Often yes. Planning permission, where needed, and Building Regulations approval are separate.
Where do I find the current local list?
On the council's planning pages. Check it on the day you submit.
