You may need a consumer unit replacement if:

  • Age – Your fuseboard is over 40 years old

  • Condition – There is visible damage, corrosion, overheating or loose connections

  • Capacity – You’re adding new circuits, appliances, EV chargers or electrical upgrades

  • EICR Report – Your Electrical Installation Condition Report recommends an upgrade

Upgrading your consumer unit significantly improves electrical safety and future-proofs your installation.
