My son and daughter in law have just bought a very nice listed building that has had electrical works carried out and certified by a few different electrical contractors. My gripe is the cooker panel switch, connected upside down, IE turn of the cooker main switch and the socket goes off as well, This circuit is certified by a contractor, If they cannot get the simple things correct it makes me wonder. I will be checking it all over for them to make sure its all ok, end of gripe
