Heritage statement in Kensington and Chelsea, from £565 fixed

Kensington and Chelsea's validation list treats buildings of merit outside conservation areas as heritage assets, and for listed buildings it wants window and door drawings at 1:20, joinery at 1:5, and the details of any tanking, underfloor heating or downlighters. We write the statement and draw those details together.

What Kensington and Chelsea Council asks of a heritage statement

From the council's RBKC Local Validation List, Heritage Statement and Note 22 (adopted 10 March 2023 edition, read 29 October 2026).

  • The list asks for a heritage statement with listed building consent applications, applications for substantial or total loss of a building in a conservation area, and works affecting the setting of a listed building or conservation area. (source, checked 29 October 2026)
  • Note 22 counts listed buildings, buildings within conservation areas, and buildings of merit or interest outside conservation areas as heritage assets. (source, checked 29 October 2026)
  • For listed building consent it expects a schedule of works, photographs of features to be altered or removed, and historic evidence such as old plans or photographs where lost features are to be reinstated. (source, checked 29 October 2026)
  • Alterations, replacements or new windows, doors and shopfronts need elevations and sections at 1:20 or less, with features such as architraves, cills, horns, glazing bars and mouldings possibly at 1:5 or less. (source, checked 29 October 2026)
  • The note also asks for details of any work involving underfloor heating, tanking, recessed downlighters or new service or drainage runs, and a detailed specification of materials. (source, checked 29 October 2026)

What Kensington and Chelsea heritage statement drawings have to show

A Kensington and Chelsea heritage statement for a listed house travels with a schedule of works and photographs of each feature the works touch. Where a sash, a door or a shopfront changes, we draw it at 1:20 in elevation and section, and the glazing bars, horns and mouldings at 1:5, because the list asks for that scale.

Hidden works count too. New downlighters, underfloor heating, tanking to a basement or a new drain run in a listed building are each described and located, so the conservation officer can see the fabric they affect.

Answers

Kensington and Chelsea heritage statement questions

What scale do window drawings need to be for a listed building in Kensington and Chelsea?
Note 22 of the council's Local Validation List asks for elevation plans and sections at a scale of 1:20 or less for any alteration, replacement or installation of windows, doors and shopfronts. Details such as architraves, cills, horns, glazing bars, transoms, mullions and mouldings may need to be at 1:5 or less.
Does an unlisted house in Kensington and Chelsea need a heritage statement?
Often, yes. The list asks for one where works affect the setting of a listed building or a conservation area, and Note 22 counts buildings in conservation areas and buildings of merit outside them as heritage assets. The council advises discussing the scope at pre-application with a planning or conservation officer.
Do I need to show downlighters and underfloor heating in a listed building application in Kensington and Chelsea?
Yes. Note 22 asks for details of any works involving underfloor heating, tanking, recessed downlighters or new service or drainage runs, with a detailed specification for all proposed materials. These works cut into historic fabric, so we locate each on the plans and describe it in the statement.
