i) Get an electrician, plasterer, and decorator around to your house to install a raft of additional mains outlets
ii) Use mains adaptors.
Rather obviously, my house is therefore full of mains adaptors of various shapes and sizes. Most of these are less than perfect. Some of the common options are...
1) The traditional three outlet plug - Stick out from the wall a long way, sometimes hard to get bulky adaptors to fit, and messy to look at with all the plugs having different orientations.
2) A recent update on the traditional three outlet plug - with the useful ability to switch individual outlets on/off - same drawbacks as the standard 3 plug adaptor.
3) A trailing gang plug adaptor - this one is a four plug model, they tend to take up a lot of room and need some floor space.
4) My recent purchase. This one was from Morrisons supermarket and cost £4.99.
The things I like about this one is that it powers four devices, all are individually switched, it stays pretty snug to the wall and the plugs are all sensibly spaced with the the orientation keeping the cables tidy.
I know that plug adaptors aren't something that people normally discuss - but I thought I'd make an exception on this occasion because I was so impressed with this simple solution to an old problem.
