Replacing a consumer unit (fuse board) in Wakefield starts from £500 and typically costs £600–£800 fully fitted and certified.

Knox Power & Data are NAPIT-registered consumer unit specialists in Wakefield — here's exactly what's included and what to watch out for.

What Is a Consumer Unit?

The consumer unit is the heart of your home's electrics — it splits incoming power into individual circuits and provides RCD/MCB protection against faults, overloads and electric shock.

Common Questions

How long does a consumer unit replacement take?

4–6 hours for a typical 3-bed Wakefield home.

Will I be without power?

Only on the day, and we keep outage time to a minimum.

Why has my electrician suggested an upgrade?

Old plastic or rewirable boards don't meet 18th Edition rules — see signs your fuse board is unsafe.

Do I need building control approval?

Yes — but as NAPIT-registered installers we handle the notification automatically.

Will my insurance still be valid?

Only if certified. DIY or non-Part-P installs can void cover.

When Should You Call an Electrician?

If your board still uses fuse wire, has no RCD, or your EICR flagged issues — replacement should be your next step.
