The consumer unit in my house is quite old and has black rubber wires going into it. Do I need rewiring?
If your house has black coloured cables entering the consumer unit or lead sheathed cables and your sockets or lights are round pin plugs then your house needs re-wiring at the earliest opportunity. Modern Cables are normally either grey or white in colour on the outside and have black and red cores or brown and blue cores inside. Black rubber cables and lead sheathed cables are obsolete and can be quite dangerous in most cases.
