Upgrade Your Fuse Board

Consumer Unit Replacement & Upgrades

Old fuse boards with rewirable fuses or early MCBs don't offer the protection of modern consumer units. A consumer unit upgrade protects your home, reduces the risk of fire and is often required by insurers and mortgage lenders.

Full Consumer Unit Replacement

We replace old fuse boards with modern 18th Edition consumer units, fitted with RCDs or RCBOs on every circuit for maximum protection against electric shock and fire.

Split-Load Consumer Units

Split-load consumer units divide your circuits between two RCDs, so a tripping fault only affects half your home rather than everything at once. Ideal for larger properties.

RCBO Consumer Units

RCBO units give each circuit its own independent protection. If one circuit trips, nothing else is affected — the best option for convenience and safety.

Additional Circuits

Adding a new circuit for an EV charger, outbuilding, hot tub or garden lighting? We'll install the circuit and ensure the consumer unit has capacity for it.

Part P Certification

All consumer unit work is notified to the local authority under Part P of the Building Regulations. We handle this for you and issue the certificate on completion.

Same-Day Completion

Most consumer unit upgrades are completed in a single day. We'll work through the circuits systematically to minimise disruption and restore power as quickly as possible.

Consumer Unit FAQs

How much does a consumer unit upgrade cost?

Consumer unit upgrades typically cost between £350 and £650 depending on the size of the property and the number of circuits. Message us on WhatsApp for a fixed price.

Do I need to notify building control?

Yes — consumer unit replacement is notifiable work under Part P of the Building Regulations. As registered electricians, we handle this notification and issue the certificate.

How long does a consumer unit replacement take?

Most replacements are completed in a single day — typically 4–8 hours depending on the number of circuits. Power is off for most of this time, so we try to start early.

Do I need a new consumer unit if my EICR failed?

Not necessarily. An EICR may identify issues that require a consumer unit upgrade, but many faults can be resolved without replacing the whole board. We'll advise you honestly.

Can I upgrade my consumer unit if I'm a tenant?

Consumer unit work requires the landlord's permission. If you're a tenant, your landlord is responsible for ensuring the electrical installation is safe.
