What Is a Consumer Unit?

Understanding your home's electrical distribution board

Your Home's Electrical Hub

A consumer unit (also called a fuse board or fuse box) is the central distribution point for your home's electrical system. It receives the incoming electricity supply and distributes it to individual circuits throughout your property — lighting, sockets, cooker, shower, and more. It also provides critical safety protection via circuit breakers and RCDs.

Old vs Modern Units

Older fuse boards use rewirable fuses that offer basic overcurrent protection but no protection against electric shock. Modern consumer units use MCBs (Miniature Circuit Breakers) for overcurrent protection and RCDs (Residual Current Devices) that trip in milliseconds if they detect current leaking to earth — significantly reducing the risk of electric shock and electrical fire.

Signs You Need a Consumer Unit Upgrade

If any of these apply to your property, it's time to upgrade

Old Rewirable Fuses

If your fuse board still has rewirable wire fuses, it is seriously outdated. These fuses provide no protection against electric shock and can be incorrectly rewired with the wrong fuse rating, creating a fire risk.

No RCD Protection

If your consumer unit has no RCD (Residual Current Device), your electrical system offers no protection against earth faults. An RCD trips in milliseconds to prevent fatal electric shock and reduce the risk of electrical fire.

Failed EICR

If your property has received an unsatisfactory EICR result, a consumer unit upgrade is often recommended as part of the remedial works. Outdated consumer units are one of the most common reasons for EICR failures.

🔄

Wooden-Backed Board

Older fuse boards with wooden backs are a fire hazard. Modern consumer units must be manufactured from non-combustible material (metal or flame-retardant plastic) to comply with 18th Edition regulations.

🔄

Over 25 Years Old

If your consumer unit is more than 25 years old, it is likely non-compliant with current regulations and may not provide adequate protection. An upgrade ensures your home meets modern safety standards.

🔄

Frequent Tripping

If your fuses regularly blow or circuit breakers frequently trip, it could indicate an overloaded or faulty consumer unit. An upgrade with correctly rated MCBs and sufficient circuits resolves this.

Consumer Unit Upgrade FAQ

Common questions about fuse board replacement and consumer unit upgrades

How much does a consumer unit upgrade cost in Manchester?

A consumer unit upgrade with Manchester Compliance starts from £850 + VAT. This includes the supply and installation of a new 18th Edition consumer unit with RCD and MCB protection, full electrical testing, an Electrical Installation Certificate, NICEIC Building Regulations notification, and a 6-year Platinum Promise guarantee.

How long does a consumer unit upgrade take?

A standard consumer unit upgrade typically takes 4-6 hours to complete. This includes isolating the supply, removing the old unit, installing and wiring the new consumer unit, full testing of all circuits, and issuing certification. Your electricity will be off for most of this time, so we recommend planning accordingly.

How do I know if I need a consumer unit upgrade?

You likely need an upgrade if: your fuse box still has rewirable fuses, you have no RCD protection, your EICR has returned unsatisfactory results, you have a wooden-backed fuse board, your consumer unit is over 25 years old, you are adding new circuits (e.g. for an EV charger or extension), or you experience frequent tripping or blown fuses.

What is the difference between a consumer unit and a fuse board?

They serve the same purpose — distributing electricity and providing overcurrent protection. The term 'fuse board' typically refers to older units using rewirable fuses, while a modern 'consumer unit' uses MCBs (Miniature Circuit Breakers) and RCDs (Residual Current Devices) that offer much better protection against electric shock and fire.

Do I need Building Regulations approval for a consumer unit upgrade?

Yes. A consumer unit replacement is notifiable work under Part P of the Building Regulations. It must be carried out by a registered electrician (such as an NICEIC Approved Contractor) who can self-certify the work and notify your local building control. Manchester Compliance handles all Building Regulations notification as part of our service — there is no additional cost or hassle for you.
