I live in a 3 bed semi which had the loft converted to one room in 1991 by a previous owner. The conversion complied with building regs at that time. If I want to install an en-suite in the loft will I have to bring the entire loft up to current regs or just ensure that the en-suite complies?
Similarly, if I want to install an additional Velux window in the roof, can I do this without having to bring the entire loft up to current regs?
I have asked my local council these questions but hoped for a quicker reply from here. :D
