hi, just after some legal advice. I went to local open day at birmigham city college for gas course. They told me i will also need to do water regs as its illegal to work on water without water regs, and my public liability is not valid as i dont have water regs, i do some basic plumbing work now and again. im very confused by it all. can someone please clarify what if anything i need to work on water pipes, changing taps etc or is college just trying to get more money out of me?
