SJI Electrical installs modern consumer units and upgrades older fuse boards — based in Paisley and working across Bridge of Weir, Renfrewshire and the wider Greater Glasgow area.
The consumer unit is the central control point of your property's electrical system. We inspect the existing board properly before recommending an upgrade.
Three quick questions, then it goes straight to SJI on WhatsApp.
Bridge of Weir is a Gryffe Valley village of roughly 4,920 people (2020 figure), and a good deal of its housing dates from the affluence that followed the railway's arrival in the 19th century. Older-style boards still turn up in stock of that age, and a consumer unit upgrade is one of the most common — and most cost-effective — improvements a property of that kind can have.
That said, we never assume a board needs replacing purely because it looks old. A proper inspection tells us whether it's genuinely due an upgrade or still doing its job safely. Signs worth a look:
A modern consumer unit brings your property's electrical control point up to current standards.

Better protection across the installation, plus increased capacity for additional appliances.

Enhanced electrical safety and improved compliance with modern standards throughout the property.

Better circuit organisation, clearer circuit identification and greater day-to-day reliability.

Every upgrade is fully tested with certification issued on completion.
Considering a full rewire? →Every upgrade follows the same structured sequence, whether it's a period villa in the older part of the village or a more recent house on its edge. Nothing is rushed and nothing is skipped, however straightforward the job turns out to be.
Most installations are completed within one day, depending on the property — and we agree the date with you in advance so you know exactly when the supply will be off.
