What does Slough Borough Council need to validate an application?

• The council's local validation list was formally adopted on 1 January 2026; an invalid application is given 4 weeks to be made valid and is then returned. (source)
• A block plan (recommended 1:100, 1:200 or 1:500) showing trees on the site and on adjacent land, and the extent and type of any hard surfacing with its drainage. (source)
• Cross sections, showing window positions and head heights, for a loft extension or where ground levels change. (source)
• In the Green Belt, the elevations must come with original, existing and proposed volume calculations, original meaning the house as it stood on 1 July 1948 or as first built. (source)
• A BS 5837 tree survey with impact assessment, method statement and tree protection plan for trees over 75mm in diameter within influencing distance of the work, on the site or next to it. (source)
• Site and finished floor levels in Flood Zones 2 or 3, on land that is not reasonably level, and for basements or swimming pools. (source)

Article 4 directions in Slough

An Article 4 direction removes permitted development rights, so work that needs no application elsewhere needs one here. Check yours with the permitted development checker.

• Caravans and moveable structures, whole borough. A direction approved on 5 March 1952 removes the right to station a caravan or moveable structure on land for up to 28 days a year anywhere in the borough. The council notes that parking a touring caravan within a house's curtilage does not normally need permission if it is not lived in or stored for sale. (source)

The council lists five conservation areas: Colnbrook, St Bernard's School, St Mary's Church (Langley), Sussex Place/Clifton Road and Upton Park/Upton Village. (source)
