💬 Questions about consumer unit replacement in Lewisham

Why replace my fuse box?

Older units may lack modern safety protection. A new consumer unit with RCDs can help protect against shocks and electrical fires.

Does it need a certificate?

Yes. Replacing a consumer unit is notifiable under Part P of the Building Regulations in England. Ask for the certificate when the job is done.

How long does it take in Lewisham?

Usually half a day to a day. The power is off for part of that time, so plan around it.
