Ring the bloody DNO and tell them that supply tails or in a unsafe state. They will put a new cutout and 20mm tails in. No charge for an domestic building if the install is old enough and they will also change the meter to a smart meter if you live in the right area and have the right DNO. So if you or mad then you can put what ever size of fuse you like in. Or ring them and and ask to talk to an engineer and ask them?
