Signs You Need An Consumer Unit Upgrade

Your residential consumer unit is crucial in distributing electricity throughout your home. But like any other system, it can wear out or become outdated. Watch out for these warning signs:

• Flickering or dimming lights
• Frequent circuit breaker trips
• Burning smells or discoloured outlets
• A consumer unit that’s hot to the touch
• Crackling or buzzing sounds from the consumer unit
• An old fuse box is still in use
• Installing new high-power appliances or systems (like electric showers or EV chargers)

If you recognise any of these, it might be time for a home consumer unit replacement. Upgrading your electrical service consumer unit ensures you meet modern safety standards and prevent potential hazards.

2. How do I know if my consumer unit is safe?

A safe consumer unit will not emit heat, buzzing sounds, or show signs of burning or rust. It should have circuit breakers instead of fuses and should be labelled correctly. If you’re unsure, have it inspected by a certified electrician.

3. What does an electrician do during a consumer unit upgrade?

During a consumer unit upgrade, the electrician will disconnect power, remove the old unit, install a new electrical service consumer unit, connect and test all circuits, ensure compliance with safety regulations, and complete final inspections.

Most home consumer unit replacements take between 4 and 8 hours, depending on the job’s complexity and whether rewiring is needed. Additional time for inspections or power reconnection by the local utility company may be required.
