There's been a few posts on here recently regarding poor workmanship on installations. Some have said it should be illegal for anyone other than a qualified and registered electrician to carry out wiring and testing. While I agree with this to a certain extent, how would it be enforced? Anyone can buy the gear for a wiring job, so you would have to stop it being sold to the general public., Which would upset a lot of shops! Plus, of course a lot of the poor work is carried out by qualified and registered electricians. More checking? If I rewire my house, whether it's a good or a bad job, no one would know, unless something went wrong, which of course it may. If I then sold the house, a certificate may be needed, which I wouldn't have. No problem, get a test done (is it a rice?), or drop the price to allow for a rewire. I'd be interested in any thoughts.
