I live in a small block of flats converted in 80s. We need new front fire doors fitted. The management company are saying they need new frames, the lott, over 2k a door. One fiat had the door done a few years ago to comply so it could be sold. It's just an fd30 internal fire door from what I can see, no new frame. I can do that my self, I'm a competent trade, it will cost me no more than £200. Surely that's OK and should be for all the flats?
