Performed electrical testing on a 4 bedroom house today of a BNI chapter colleague (BNI Blaze, Hitchin). The installation is unsafe in a number of ways, namely it lacks any 30mA RCD protection of its circuits and has no main equipotential bonding of its gas and water supply. The consumer unit is also obsoletem being of the 1361 fuse holder type. Needs replacing with a nice Hager 17th Edition dual RCD board.

I also joined Twitter and Twellow today.
