I am so glad that we did!
If you take a look at the picture I took today, you will see that someone, obviously with no electrical knowledge at all, had connected a 6mm cable to a 2.5mm! With a 5amp connector block! Also on a 45amp mcb. The connector block had completely melted on the phase / live conductors side of the connector. To be honest I could go on and on about this installation, i.e. the connecor you see in the picture was inside an airing cupboard for anyone to touch!, But all I can say is that I can only be thankful for RCD's. I would guess that if there were no rcd in this property something more serious may have happened.
My advise to the public reading my electricians blog, If you see anything like this in your home then contact your local electrician. They will be able to advise you further. To find an electrician local just go to http://www.mylocalelectrician.co.uk/ and simply enter your postcode.
