Common questions

How do I know if my house needs rewiring?

Old rubber or fabric cable, a fuse box rather than a consumer unit, frequent tripping or scorch marks are common signs. An EICR inspection will confirm it.

Can I live in the house during a rewire?

Yes, but it takes longer and costs a little more because rooms have to be done one at a time.
