To give it a bit of context a forty year old installation was installed around 1981, so it should have complied with the 14th or 15th edition of the Wiring Regulations and a VOELCB was still acceptable to protect a TT earthed installation rather than a RCD.
Who mentioned a TT supply? In the early 80s we were well into P.M.E. earthing.
