Save us from cowboys...

Roger (Roger ) gurgled happily, sounding much like they were saying:

Now, let me think back...

Lifted the floorboards above the hall light, saw that it was attached with tape only, put floorboards back with that "Oh, gawd, this is going to be fun - tomorrow..." feeling, turned the light on - and it just flickered and fizzled. I'd not even TOUCHED the wires. Just looked at 'em...

Then there was the spur to the garden shed.

One length of lighting T&E, "protected by" a rubber hose pipe inside a poured concrete retaining wall. The mini-ring round the shed was joined at a 13A plug. Which was plugged into a socket. Which was connected to a short length (about 2ft) of that really cheesy translucent-gold-covered two-core lamp flex. Which had a plug at the other end. Which was plugged into one of those three-way granny-burner plug & socket extension thingies. You know the ones, the cube-shaped ones. Which had holes drilled in the pins and was BOLTED TO the wire from the house... Then, over the years, the whole mess (tucked behind the ply inner wall and the "Genuine Lambretta" plastic parts bags used as insulation) had become utterly overgrown with ivy.

Thank gawd the house end wasn't actually attached to anything any more.
