Quick FAQs
Do I have to move out for a rewire?
Not always. We can phase the work room-by-room, but a full rewire is faster (and cheaper) in an empty home.
Will I be without power?
For a fuse board swap, expect several hours of downtime. For rewires, we plan temporary supplies where possible.
Do you certify the work?
Yes. You’ll receive the relevant Electrical Installation Certificate and Building Control notification where required.
Can you advise on future needs (EV, solar, extensions)?
Yes. We design today’s system to support tomorrow’s upgrades.
