Went to do a job today and asked the customer how old the CU was (as it only looked a few years old). She told me it was installed 5 years ago.
When I asked if she had any documentation, she rolled her eyes and said that the plumber who installed it (who claimed he was also a qualified electrician) had refused to give her any certificate after he had been paid.
She tried phoning him several times but eventually he blocked her number....
I was very impressed that even though there are 3 spare ways on the RCD side, he managed to put both RFC's on the main switch side....
