Hello I’m trying to replace the windows in our flat, the council have got me jumping through hoops to get planning permission. Our windows are currently leaking in water and heat out, but the application has been paused because I need to provide a D12 fire safety policy, I did include an old fire safety check from the house insurance but this wasn’t sufficient for them, they want a specific d12 one.
After a quick google search, it seems for something as simple as replacing windows I shouldn’t need a qualified assessor to do it, but I have no idea how to write this myself.
Does anyone have any experience with this or know how I can get one done cheaply?
Thank you xx
