was this in London? I think everything is generally a little bit cheaper up here and there are other factors, size of the house etc. I’ve spoken to a few people (they’ve not had one done recently though) and I’ve been advised to get the loft/roof surveyed before I do anything to make sure it’s suitable and then get quotes. Getting separate tradespeople was also recommended, as opposed to one company doing everything start to finish, to try and keep costs down but I feel like that’s such a hassle. Anything over 50K just wouldn’t be feasible but we’ll see. Thanks for your replies x
