Consumer Unit Upgrades

If your fuse box is outdated, damaged or no longer suits your home, we can assess it and recommend a suitable consumer unit upgrade. Contact us to arrange a survey and receive a written quotation before work starts.

What a consumer unit upgrade changes

An older fuse box may not provide the protection or capacity your home now needs. A modern consumer unit protects each circuit and makes it easier to isolate a fault, helping you use appliances with greater confidence.

If you’re extending the installation, we check whether the board can accommodate additional circuits. You receive clear labelling and a tidy finish, so operating the electrical system remains straightforward.

Better circuit protection

An older fuse box may leave circuits with limited protection, so we fit a modern board suited to the installation and its risks.

Faults are easier to isolate

When one circuit develops a fault, clear circuit separation helps us identify it and lets you isolate the affected area.

Capacity for added circuits

If you’re adding an extension, kitchen appliances or an EV charger, we check whether the existing installation can safely accommodate the extra demand.

Surge protection considered

Sensitive appliances can be affected by voltage surges, so we assess whether surge protection should be included in the upgrade.

Clear labelling

Unclear labels make a fault harder to manage, so we identify each circuit clearly and leave the board straightforward to operate.

Electrical work you can rely on

Your consumer unit is upgraded by NICEIC-registered electricians, with the installation checked and the relevant paperwork provided.

Questions About Consumer Unit Upgrades

How disruptive is a consumer unit upgrade?

Before work starts, we discuss access, protect nearby surfaces and isolate circuits safely. We then test each circuit, label the board and leave the installation tidy and ready to use.

How long does a consumer unit upgrade take?

The expected duration depends on the existing board, circuit condition and any remedial work. During the survey, we explain the schedule, isolation requirements and preparation needed beforehand for everyone.

Can a consumer unit be installed without rewiring the whole house?

Often, no. We assess the existing circuits, earthing and bonding before replacing the board. If testing identifies unsafe wiring or faults, we explain clearly any remedial work separately before proceeding.

Do I need a new consumer unit if my fuse box still works?

Not always. If the existing board provides suitable protection and passes testing, it may remain. We recommend replacement where safety features, capacity or condition no longer meet household needs today.

How much does a consumer unit upgrade cost?

The price reflects the replacement board, circuit alterations and any remedial work found during testing. We explain each item separately, so you can approve the necessary work with clear costs.

A Safer, Clearly Documented Electrical System

Since 1983, Alderminster Group has upgraded consumer units in older homes where wiring, earthing and circuit capacity need careful assessment. Our NICEIC-registered electricians test the installation before and after work, leaving certification and circuit schedules for your records.

Clear Advice, Careful Work and Reliable Support

A consumer unit change can expose faults elsewhere, especially in an older installation. We explain what we find in plain terms and separate essential work from improvements that can wait. You can then decide how far the job should go.

If access is tight, we plan the route before starting. We protect nearby surfaces, keep cables organised and work methodically around occupied rooms. You’ll know what we’re doing and why, without having to interpret technical terms.

Once the upgrade is complete, we run through the switches and protection with you. If a circuit trips later, our team can talk through sensible first checks. The finished installation leaves you clear about what was changed and what to do next.

Arrange Your Consumer Unit Upgrade

Tell us what’s prompting the upgrade, whether it’s repeated tripping, planned alterations or an older installation. We’ll discuss the next step, answer practical questions and arrange a survey before providing a clear written quotation.
