An electrician will be able to advise you - please ensure you use a registered electrician. You can find one or check that your electrician is registered via our website.
The installation of a new fuse box is notifiable work under building regulations and will require an Electrical Installation Certificate once installed. You should always use a registered electrician for any notifiable work in the home.
