Building Regs and the Local Authorities interpreting them are now insisting on phone sockets being located at least 500mm off the floor but below 1200mm in line with the rules for sockets and light switches! I have even come across one authority who insisted that TV aerial sockets were also met those rules.
Absolutely ridiculous in a lot of cases and I had to argue about mine when an extension was built.
