We're using Econoloft for a loft conversion. We signed the contract with them at the end of December and were told that they'd start work in 3 months.
It's been 3 months now and they haven't even finished the drawings! They've said we won't get a date for the work to start until we've got the party wall stuff sorted (we can't start that until they've finished the drawings) and then it will be 6-8 weeks before they've got a team free to start work.
So that will be at least 7 months rather than 3. They won't even have started by the date they said they'd have finished! 
Is that typical or have we just been unlucky? If you've had a loft done by them, how long was it from start to finish?
