Hi, not sure if this should be property or legal but just looking for a bit of advice.
We got our windows changed in October from old draughty faulty aluminium sash and case windows to upvc tilt and turn. They were the only window type we could really afford. We are currently trying to part exchange our flat for a new build and as part of the missives they asked for proof of planning permission for our windows. Turns out we are in a conservation area (Edinburgh flat) and should have applied for planning permission. We are now applying for retrospective permission but looking at previous applications I am sure we will be refused and told to change back to sash and case.
On the one hand, I know this is totally our fault for not checking about planning permission, but didn't even occur to us especially as there are other PVC windows and also a new build development going up. My question though is (finally)... Does the company that put in the windows have any responsibility/liability? A couple of people I've spoken to have said they do and I'm just wondering where we might stand?
Would be very grateful for any advice.
