Do I need permission from my neighbours in order to carry out a loft conversion?

Yes, but only if you have adjoining neighbours. You would need what’s called a "Party Wall Agreement”. You are required by law to give your neighbour two months notice of any work being undertaken by the shared (party wall), if the neighbour requires the wall to be surveyed it would be to the cost of the person requiring the loft conversion. No one can stop a loft from being built but the process can take up to two months. We provide all of the relevant paperwork on this matter and most of the people served these documents are happy with the work to precede as we guarantee to repair any damage, if it were to occur from the loft conversion process.
