Consumer Unit Upgrades in Colchester & North Essex

Modern fuse boards fitted safely, tested properly, and certified.​

Consumer unit (fuse board) replacements and upgrades

Gray Logic Electrical is based in Colchester and carries out consumer unit upgrades across North Essex and nearby areas for homeowners, landlords and small businesses.

If your existing fuse box is outdated, has no RCD/RCBO protection, shows signs of overheating, or you’re upgrading as part of renovation work, we can assess the installation and recommend the right option — not a one-size-fits-all board swap.

What’s included

  • Pre-checks and assessment
    We look at earthing and bonding, the condition of the existing equipment, and any issues that should be dealt with at the same time.
  • Supply and installation
    A new consumer unit fitted neatly with correctly selected protective devices.
  • Testing and certification
    The installation is tested and documentation issued in line with BS 7671 where applicable.
  • Clear labelling and handover
    Circuits labelled, and you’ll be shown what’s been changed and how to isolate safely.


Why upgrade your consumer unit?

  • Improved protection: modern devices can provide better fault protection for people and property.
  • Reliability: fewer nuisance trips once faults are correctly identified and circuits are in good order.
  • Compliance and documentation: helpful for landlords, insurance queries, or when selling/letting a property.
  • Peace of mind: a safer, more maintainable electrical setup.
