Heritage statement in Islington, from £565 fixed

Islington's April 2024 validation list spells out what a heritage statement for a listed building must hold, from a schedule of every work to annotated photographs. For windows and doors it asks for drawings at 1:20, 1:5 and 1:2. We write the statement and draw the details together.

What Islington Council asks of a heritage statement

From the council's Validation Requirements (April 2024 update), section 3.5 Heritage Statement (adopted April 2024).

  • Islington has 42 conservation areas, each an area of special architectural or historic interest whose character or appearance it is desirable to preserve or enhance. (source, checked 25 October 2026)
  • Section 3.5 of the validation list asks a heritage statement for listed building consent to include an analysis of significance, a schedule of works with materials and methods, the impact on that significance and why alternatives could not be accommodated, annotated photographs, and a justification for the works. (source, checked 25 October 2026)
  • Where lost or damaged features are to be reinstated, the council asks for historic evidence such as historic plans or photographs, or else evidence of original features on similar properties. (source, checked 25 October 2026)
  • For alterations to windows, doors and shopfronts the list asks for existing and proposed elevations and sections at 1:20 or less, details such as frames, cills, mouldings and meeting rails at 1:5 or less, and glazing bars at 1:2. (source, checked 25 October 2026)

What Islington heritage statement drawings have to show

Islington's checklist reads like a contents page, so the statement follows it: the significance of the listed building and its conservation area, a numbered schedule of every work, the effect of each on that significance, and the reasons a less harmful option would not work. Photographs are annotated with the room and the drawing reference they relate to, as the list asks.

The drawings carry the most weight on window and door work. We draw replacement sashes and doors at 1:20, the profiles of frames, cills and meeting rails at 1:5 and the glazing bars at full or half size, so the officer can compare them with the originals. Where a lost feature is reinstated, the statement shows the historic photograph or the matching original on a neighbouring house.

Answers

Islington heritage statement questions

What does Islington want in a heritage statement?
For listed building consent, section 3.5 of Islington's validation list asks for an analysis of the significance of the building and any conservation area, a schedule of works with materials and methods, the impact on significance, annotated photographs and a justification. Where harm is proposed, it asks why mitigation or alternatives could not be accommodated.
What scale drawings does Islington need for replacement windows?
Existing and proposed elevations and sections at 1:20 or less, with details such as window frames, architraves, cills, mouldings and meeting rails at 1:5 or less, and glazing bars at 1:2. These details let the Islington conservation officer compare new joinery with the original, which matters most on listed and conservation area houses.
How many conservation areas are there in Islington?
Islington has 42 conservation areas. If your home is in one, alterations that change its character or appearance are judged against the council's Conservation Area Design Guidelines, and a heritage statement explains how your proposal preserves or enhances the area. Our first step is to check which area, if any, your address is in.
