Planning in Brent

Before submission

Validation requirements

Brent publishes separate validation lists for householder applications and full, outline or technical details consent.

• Use the householder list for extensions or alterations to a house, rather than assuming one checklist applies to every proposal.
• Obtain the current checklist from the council before submission; supporting reports depend on your site and application type.

Timescales

Realistic decision times

Statutory target

The national determination period set in law, counted from validation. A target, not a guarantee.

Actual processing time

What the council's published performance data shows in practice, including extensions of time.

Allow for validation before the decision period starts. The usual statutory determination periods in England are 8 weeks for non-major applications, 13 weeks for major development and 16 weeks where environmental impact assessment is required, unless a different period is agreed.

• These are statutory targets, not a measured borough average or a guarantee. No current borough-specific average has been verified for this guide.
• An incomplete submission, amendments, committee referral or an agreed extension of time can extend the overall programme.
• Ask the planning team about its current validation queue before setting a construction date. Prior approval and other specialist applications can have different statutory periods.

Permitted development

Article 4 restrictions

These are selected directions, not an exhaustive address search. Read the council’s current map, schedule, commencement date and any later modifications for your property. A conservation area is not automatically an Article 4 area, and a direction affecting changes of use does not necessarily restrict a home extension. Confirm the responsible planning authority too: some development-corporation areas have separate arrangements.

Brent Council has implemented various Article 4 directions to remove specific permitted development rights across the borough. These measures require planning permission for certain changes of use that would otherwise be permitted.

• Planning permission is mandatory for changing residential dwellings (Class C3) to small HMOs (Class C4), effective since 1 November 2022.
• Directions across Strategic Industrial Locations, Site Allocations, Town Centres, and other areas remove Class MA rights (commercial to residential) and Class ZA rights (demolition/redevelopment) to protect employment floorspace.
• All residential conservation areas in Brent are covered by Article 4 directions, including specific controls on front garden parking in the former Manor Close conservation area.
