Consumer Unit Upgrades in Chelmsford
Based in Great Baddow, BSJ Electrical carries out consumer unit and fuse board upgrades in Chelmsford. We assess your existing board, circuits and earthing before recommending a replacement, so the proposed work reflects the condition and needs of your property.
At BSJ Electrical, we provide professional consumer unit upgrades in Chelmsford, Essex, Hertfordshire and London. Our qualified electricians replace outdated fuse boards with modern, safe and efficient consumer units that meet current wiring regulations (18th Edition BS 7671).
Why Upgrade Your Consumer Unit?
Many older properties still have fuse boards fitted with re-wireable fuses or outdated components. These may not provide adequate protection against modern-day electrical usage. By upgrading your consumer unit, you benefit from:
- Improved safety – reduces the risk of fire and electrical shock
- Current standards – the replacement board is selected and installed to the applicable wiring requirements
- Circuit protection – appropriate RCD or RCBO protection is selected for the installation
- Future-ready – supports additional circuits for EV chargers, solar panels and new appliances
- Peace of mind – knowing your home or business is properly protected
Signs You May Need a Fuse Board Upgrade
- Frequent tripping of circuits or blown fuses
- Burn marks, buzzing noises or smells coming from the consumer unit
- An old fuse board with wooden backing or re-wireable fuses
- Lack of RCD protection
- Adding major new electrical installations, such as an EV charger or solar panels
If you’re unsure whether your consumer unit needs upgrading, our electricians can carry out a professional inspection and provide honest advice.
Our Process
- Assessment of existing circuits, earthing and bonding, with any remedial work identified before replacement
- Agree the quotation and planned power interruption, then safely remove the existing board
- Installation of a new, fully compliant consumer unit
- Full testing and certification (EIC)
- Handover with clear explanation of your new system
The quotation depends on circuit count, board specification, access and any faults or bonding work identified during assessment. Replacing a consumer unit does not replace the existing wiring or resolve every circuit fault; we explain any additional work needed.

Frequently asked questions
Does a new consumer unit mean I need a full rewire?
Not automatically. The existing circuits and their condition need assessing so any faults or other work can be identified before the upgrade.
Will the power be off during the replacement?
Yes, the work requires isolation and testing. Discuss the likely interruption and tell us about equipment or occupants that need special arrangements.
What should be included in the quote?
Ask about the proposed equipment, inspection and testing, certification, applicable notifications and how any existing defects will be handled.
