Heritage window guides
Plain answers to the questions that decide what you are allowed to do.
Guides covering the questions owners and architects ask before a window application: what a listed building window survey is, whether double glazing is possible, what a conservation area permits, and how the repair-or-replace decision is actually made.
What a listed building window survey records, who it is for, and when you need one, from the surveyors who write them, reviewed against current guidance.
Whether your listed building can take double glazing, from very slim vacuum glass in original sashes to slimline units in new like-for-like sashes.
When replacing windows in a conservation area needs planning permission, what an Article 4 direction changes, and how to avoid a refusal.
How to tell whether a period window can be repaired, what a competent repair looks like, and when replacement is the honest answer.
When window work in a listed building needs consent, what counts as repair rather than alteration, and the evidence that makes an application succeed.
Where do the heritage window guides start?
Start with listed building consent if the building is listed, and with the conservation area guide if it is not. Both set out who decides and on what evidence. The double glazing and repair-or-replace guides then deal with the two decisions that follow, and each is checked against the legislation and the Historic England guidance it cites.
