Likelihood of permission to upgrade Listed Building windows to Double/Triple Glaze?

flashforward

Just wondering has anyone had, or know of anyone who has had, success in doing this on a late 1800's or similar built house?
Assuming you were willing to put the money into modern equivalents like the below:

From all my reading I am getting mixed signals re. Seek forgiveness vs Look for permission with anything to do with a listed property...

Upgraded windows are something in my opinion that should be absolutely acceptable if they are similar in appearance to the original single glazed frames however this appears to be decided on the whim of someone who will never have to step foot in the house.

Bear in mind that these decisions are made by dedicated conservation officers and conservation planners. People that have studied and dedicated themselves to the conservation profession, so it will not be decided by your average planner.

Conservation planning, the people have a passion for the conservation of these buildings, so you can be sure that they will put a lot of thought and consideration into your proposal.

Very much hinges on the local conservation officer. I've seen it tastefully done in some properties, including ones owned by the state!

Where are you based OP?

I guess my question is whether people have had success with conservation planners prioritising the actual conservation of the property ie. keeping it inhabited vs keeping it 100% original and letting it fall to rack and ruin.

Conservation is both protection and restoration, unfortunately both can not always go hand in hand...

Double glazing (for heat) shouldn't be a particular problem if the windows can take it. However, the extra weight of the glass and any counter-weights may mean replacing the windows, which might not be acceptable to the council.

Triple glazing (for sound) may be another matter, depending on the design used, as it may affect the look of the windows / building. Triple glazing is typically 150-200mm away from the main window.

We have - but it tends to depend on the location and officer in question. There are some really good ones out there who will sensibly assess your proposals with a view to protecting the heritage of the building and country whilst allowing continued use. They know quite well what can happen if restrictive rules prevent a building from being occupied.*

However - there are also some terrible ones!!!

That's why I asked about location!

(*Bear in mind if you own a protected structure it is against the law to let it go to ruin - you can be taken to court and if you continue to fail to maintain it the local authority can seize it. This has happened in one location of which I know.)

"Similar in appearance" means what though?

White PVC sash with stuck-on glazing bars could be argued to be "similar in appearance" to painted wooden Georgian sashes, but close up they look terrible.

edit: IGS have a useful register which includes suppliers of replacement windows which may be acceptable:
