Volex VT1507 1 to 2 Gang Socket converter
I'm decorating (read doing up) the house I bought last year and there are single sockets everywhere. Not being much of a builder but capable of the basic electrical works I picked up a Volex socket convertor to try it out. I paid about 8 quid from the The Range in store and am quite impressed. It's only about double the depth (protuberance) of a single socket. I want some more but baulked at the idea of 8 quid each for 10 of them. So after digging around on tinternet a bit I found them at 24-7 electrical for 94p each. OK so the postage is steep for just the one, but I just bought 10 and postage went up to £8.49, but these still work out at only £1.79 each, which is about the same as a cheap single socket. The converter replaces the single socket item and screws into the original single box. Simples.

Most places want 8 quid + for this so I reckon it's a bargain :)
