Double glazing in a listed building?

[Amateurish]

I'm about to receive a very large estimate for repairing and replacing a large number of rotten timber casement windows and doors in my listed property. I wondered if this might be a good opportunity to put in some double glazing. I wondered if anyone had any experience getting planning approval for these kind of works - or any recommendations as to the kind of product which might be acceptable. The property is about 500 years old. Cheers

It depends entirely on the individual building (and to a slightly lesser extent the attitude of the individual Conservation Officer).

It is therefore pointless trying to draw any inference from anything anyone says on here: you need to discuss it with the CO at your local authority.

Cheers, is this something that can be done on an informal basis, or does it need a written application etc

1 or 2 listing OP?

Equus is (as others have said) on point with his post.
I do have experience with replacing windows in a listed commercial building - sound out your PO and maybe find a company that specialise in dealing with heritage and go from there.

Grade 2.

The purpose is to improve heat retention as this house leaks heat at a ridiculous rate.

Thanks for all the advice so far, I will contact our local CO to discuss.

As for the existing windows, they are 20th-century replacements, single glazed and set within openings with an original shallow arched head, with various masonry and render used as infill between the rectangular frames and the masonry. Presumably installed in the 70s when the property underwent significant renovations.

I pointed out that the house was Listed - i.e. there was a list of work done.

That isn't the meaning of 'listing'. The actual description of the building given on the statutory listing is quite brief.

You could potentially try to piece together the recent (post 1948) architectural history of the building from documentation on each individual LBC application held by the Local Authority, but that is also problematical and again the information may not be all that comprehensive (or reliable).

The listing says "Late C20 casements with glazing bars."

A couple of pictures may help.

To see the condition of the timber or to see the style of the casements within the context of the property? It's timber framed with close studding and some victorian rebuilding in brick.
