In short No. Unsafe Yes, Non-compliant with the current regulations (BS7671:2008) Yes, but not illegal! If the fusebox is old and has fuse wire type fuses, it is worth upgrading it, as modern ones have RCD protection built in, which will literally save your life in the event of a fault.
Also know, are old fuse boxes dangerous?
Fuse box. Fuse boxes are old electrical panels that use fuses instead of circuit breakers to protect your wires from becoming overloaded. Why they're unsafe: Fuses aren't inherently unsafe. They work just like circuit breakers (except they can't be reset and must be replaced.)
how do I convert an old fuse box to a new one?
- Step 1 - Get Permission. You can do a lot of the electrical work around your home yourself, but you will have to get permission from your local authority.
- Step 2 - Remove the Old Fuse Box. Have the main electrical power shut off by your supplier.
- Step 3 - Add the New Fuse Box. You can now start to add the new fuse box.
The prices include testing and fixing any minor faults (most properties are likely to have at least one minor fault somewhere).
