How to choose the right consumer unit for your home?

Choosing the right consumer unit—also known as a fuse box or distribution board—is a big decision for every UK homeowner. This is the bit that controls the electricity supply to your home and protects it from faults and fires.

Make sure you choose a unit with the right level of protection for your home and occupants.
