Redbridge planning guide: the validation list, the Housing Design Guide and the invalid-application charge

Policy LP30 in the Redbridge Local Plan 2015-2030

The Redbridge Local Plan 2015-2030 was formally adopted at Full Council on 15 March 2018, according to the council's local plan page. The plan itself notes that Redbridge is “overwhelmingly a residential borough” and that the council “deals with over 2,000 planning applications by householders in a typical year”, with the great majority to extend or adapt dwellings “built perhaps a century ago”. Our Redbridge planning permission page and house extension drawings in Redbridge cover the drawing sets.

Policy LP30, Household Extensions, is the one to read. The council will support householder development that “complements the character of the building, particularly in terms of scale, style form and materials” and “is subordinate to the existing building in terms of size, scale or height”. It also asks that development “avoids adverse impacts on the sunlight/daylight received by neighbouring properties” and “respects the privacy of surrounding residents, having regard to the position of windows and layout/use of rooms”. The policy adds that officers will point residents to the council's householder design guidance.

That guidance has since been replaced: the Housing Design Guide SPD, adopted in September 2019, says it replaces the 2012 Householder Design Guide, and it is listed on the council's supplementary planning documents page.

The August 2026 list: file format, labels and the charge

Redbridge's Local and National Planning Application Requirement List, dated August 2026, is linked from the council's validation requirements page, which also carries a quick-guide matrix for householders. Both sit beside the list rather than replace it.

The format rule is blunt: “All plans must be submitted as separate single page PDF files. Other document types, or multiple page PDF files, will not be accepted.” Every drawing must be labelled as proposed or existing, and applications “will be made invalid for incorrectly labelled plans”. Each states its scale; floor plans and elevations are drawn at 1:50, 1:100 or 1:200, the location plan at 1:1250 or 1:2500 and the block plan at 1:200 or 1:500.

The cost of getting it wrong is written into the list. Administration charges of £235 for major applications, £140 for non-major commercial or new residential unit applications and £70 for all other applications are applied on invalidation, are a set amount, and come out of any refund if an invalid application is withdrawn before validation. A householder extension sits in the £70 group. This charge is the council's, separate from the statutory application fee.

Heritage: 16 conservation areas and two Article 4 estates

The council's protected buildings and conservation areas page says Redbridge has 16 conservation areas and lists guidance for each. Two have Article 4 Directions that appear on the page: Aldersbrook and Lake House (2020) and the Bungalow Estate (2017). The Bungalow Estate and Aldersbrook have their own design guides, so check those before drawing a front elevation or a roof.

A heritage statement is asked for any application that directly affects, or affects the setting of, a statutory listed building, registered park or garden, non-designated heritage asset or conservation area. Redbridge's duty planner service is split by heritage status too: the standard appointment is not open to an address in a conservation area or a statutory listed building, which must use the advanced service. A design and access statement is asked in a conservation area when the new floor space is 100sqm or more. Our heritage statement page covers the document.

Building control and the party wall

Redbridge's building control pages take building regulation applications, site inspection bookings and demolition notices, and publish short guidance for the jobs householders do: forming or converting basements, building an extension, converting a garage, loft conversions, removing load-bearing walls and chimney breasts, drainage, boundaries and the party wall. Building control is separate from planning, so a planning permission does not by itself stand in for approval of the construction.

Our building regulations reports guide sorts the drawings, a drawing check, comments answered and regularisation by where your project stands, and the party wall services guide explains the notices to neighbours that run beside either application.

Basements, fire statements and site photographs

A basement needs a Basement Impact Assessment that “must be carried out and signed by a Chartered Civil Engineer or Charted Structural Engineer [sic]”, under Local Plan policy LP31, Basement Development. It is an engineer's document, so a basement feasibility visit comes before any drawings.

For fire, a householder can provide a Reasonable Exception Statement, which the list says can be a covering letter confirming current fire safety measures stay appropriate or setting out how they change. Our fire safety statement page covers both routes.

Photographs are asked of every application, showing the parts being altered, the neighbouring windows and trees, and views from adjoining roads. The list wants no more than six images unless essential, none with people in them, and says they are not published but can be requested under a Freedom of Information request.
