Consumer unit upgrades
Modern RCBO consumer units with surge protection, installed and certified.
WeSpark Ltd replaces old fuse boards and consumer units with modern metal clad units fitted with RCBO protection and surge protection, for homes and businesses across Hertfordshire, Essex and London.
The consumer unit is the heart of the installation. Upgrading it gives every circuit its own RCD and overcurrent protection, adds surge protection for electronics and gives you a labelled, compliant board that supports EV chargers, heat pumps and future extensions.
Before any upgrade we test the existing circuits so faults are found and fixed rather than hidden behind a new board. Work usually takes half a day to a day and comes with an Electrical Installation Certificate.
What is included
- Metal clad 18th Edition consumer units
- RCBO protection on every circuit
- Surge protection devices
- Pre-upgrade testing of existing circuits
- Earthing and bonding upgrades
- Certificate issued on completion

Ask a questionMost upgrades take between half a day and a full day, including testing of all circuits.
Old boards rarely have RCD protection, so existing faults go unnoticed. New protection reveals them. We identify and fix these faults as part of the job.
Not always, but many older boards lack the capacity or protection required. We assess this on a site visit.
