I have exact same problem I got mortgage on my flat in a council owned block. Three doors to the communal stairwell (inc mine) I bought a new upvc door from council who supplied and fitted it back in 2006. Back last year they contacted me to say they needed to fit all new front doors and as I had bought mine from them (was buying it at time re monthly payments) they would give me this new one free of charge. I declined saying I like the one I had. Now they saying if my door does not meet regs, they will force me to buy new one from them and I know they cost £1000.00. I don't want a new door, I can't afford a new door ( lost job last year) and I am shocked to think anyone can force me to do this. Any advice would be most grateful. Ps am new to this forum so I hope it's easy to find any posts in reply. I am happy if someone wants to private message me.
