What Affects Consumer Unit Upgrade Costs?

Number of Circuits

More circuits need more ways (spaces) in the consumer unit and more breakers. Each additional circuit adds £40–£80.

RCD vs RCBO Protection

Dual RCD boards are cheaper. Full RCBO protection (individual RCD per circuit) costs more but offers the best safety and convenience.

Consumer Unit Location

If the existing board is in an awkward location (under stairs, in a cupboard), moving it adds labour cost.

Condition of Existing Wiring

If the existing wiring is old or non-compliant, remedial work may be needed before the new board can be connected.

Metal vs Plastic Enclosure

Metal consumer units are now required for new installations. Metal boards cost slightly more than the old plastic ones.

Additional Features

Surge protection devices (SPDs), smart monitoring, and dual-supply setups all add to the cost.

RCD vs RCBO: Which Should You Choose?

When upgrading your consumer unit, you will need to choose between dual RCD protection and full RCBO protection. Here is the difference:

Dual RCD Protection

Two RCDs protect groups of circuits

If one RCD trips, multiple circuits lose power

Cheaper option — good for budget-conscious upgrades

Meets current BS 7671 requirements

Typical cost: £450–£950

Full RCBO Protection

Each circuit has its own RCD + MCB combined

Only the faulty circuit trips — others stay on

Best safety and convenience — no nuisance tripping

Required for some new installations and HMOs

Typical cost: £750–£1,400

For most West Midlands homeowners, we recommend full RCBO protection. The extra cost is worth the convenience and safety benefits — especially if you work from home or have medical equipment.

Frequently Asked Questions

How much does a consumer unit upgrade cost in Birmingham?

A standard consumer unit upgrade in Birmingham costs between £500 and £950 for a 6–10 way board with RCD protection. Full RCBO protection costs £750–£1,200. All prices include labour, materials, testing and certification.

How long does a consumer unit upgrade take?

Most consumer unit upgrades take 4–8 hours for a domestic property. Larger boards or those requiring remedial work may take a full day. Power will be off for most of the installation.

Will I need to rewire my house to upgrade the consumer unit?

Not necessarily. If your existing wiring is in good condition, we can connect it to the new board. However, if the wiring is old or non-compliant, remedial work may be required.

Do I need building control for a consumer unit upgrade?

Yes. Consumer unit replacements are notifiable work under Part P. As NICEIC contractors, we handle building control notification for you at no extra cost.

Can I upgrade my consumer unit myself?

No. Consumer unit replacement must be carried out by a qualified electrician and is notifiable to building control. DIY work is illegal and will void your insurance.

Will a new consumer unit reduce my insurance premiums?

Some insurers offer discounts for properties with modern RCD-protected consumer units. It also makes claims for electrical fires more straightforward.
