Planning in Sutton

Before submission

Validation requirements

Sutton Council provides a local validation checklist for prior approval applications that directs applicants to national legislation.

• The Council maintains a local validation checklist for prior approval applications.
• Applicants are advised to refer to The Town and Country Planning (General Permitted Development) (England) Order 2015 for specific validation requirements.

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.

Sutton has implemented multiple Article 4 Directions to withdraw permitted development rights across specific areas and property types.

• A borough-wide direction requires planning permission for all conversions of dwellings into houses in multiple occupation (HMOs).
• A 2014 direction for Sutton Town Centre removes rights for office (B1a) to residential (C3) conversions, while a 2007 direction for Sutton Garden Suburb restricts alterations to houses on specific roads.
• The council also lists a 1984 roof-alteration direction affecting a number of specific properties across the borough—not every property. Check whether your address is included.
