The problem

Common board problems in Portsmouth

Portsmouth has thousands of converted flats and terraced houses, many with boards fitted decades ago or added piecemeal during conversion. Old fuse boxes and plastic consumer units without full RCD protection are still common.

In HMOs, boards also have to cope with several people cooking, heating and charging devices at once. An undersized or worn board can trip constantly or overheat at its connections.

We survey the installation, test existing circuits so faults are dealt with first, and fit a metal consumer unit with RCBO or RCD protection. The work is notified under Part P and you get full certificates.

Straight answers

Consumer unit replacement in Portsmouth: your questions

Can you replace the consumer unit in my flat?

Yes. We replace boards in flats of all kinds, including converted houses and purpose built blocks. If the board is in a communal cupboard, we arrange access with the building manager.

Do HMOs need a special type of board?

Not a special type, but the board must suit the number of circuits and the load. We size it properly and make sure every circuit has the right protection.

Is my plastic consumer unit illegal?

No. Existing plastic boards are not illegal, but a new or replacement unit must have a non-combustible enclosure. If yours is in good condition, it may not need replacing yet.

How long will the power be off?

For part of the day while the changeover happens. We confirm timings in advance so you or your tenants can plan.

Will you notify Building Control?

Yes. The work is notified through our Part P scheme and you receive a compliance certificate.
