I am currently on the 6KW tariff but have recently installed an electric cooker. The main fuse is starting to get hot when the cooker and other appliances are on. I realise I probably need to move to a higher kilowatt tarif maybe 9KW. I was under the impression the the system would trip out if I exceeded the 6KW but this does not appear to be happening.
What is invloved in increasing the KW do they just change the fuse or will the line to the house need changing as I notice ours is thinner than our neighbour?
