There's another layer in the UK - Historic Conservation Zone. If your property is within a zone, you are still restricted on what you can do, even if your property isn't 'listed'.

When I lived in Wales, I did some work with a bloke who did bespoke wooden windows and stuff. One of the buildings in Aberystwyh had UPVC double glazing put in the two floors above the shop front (it was a HMO student accommodation).

As the area was a Historic Zone, the council made them rip them all out and replace them with single glazed wooden sash windows at their own expense. Del used 3mm glass rather than the required 2mm as it gave a smidgen more insulation. The windows weights he used were perfect - they were the original ones that had been given to him by the company who ripped out the old windows and fitted the UPVC ones.
