SJI Electrical replaces and upgrades consumer units across Bishopton — the older village and the newer Dargavel Village homes alike. The consumer unit is the central control point of your property's electrical system, and it's the one component that dates faster than the rest.
Most installations are completed within one day, depending on the property, with full testing and certification on completion.
Three quick questions, then it goes straight to SJI on WhatsApp.
Bishopton is really two villages sharing a name, and the reason for a board change differs between them. In the original village, the trigger is usually age — an older-style fuse board still fitted, faults or frequent tripping, or a property being prepared for rental or sale. Those are the classic cases, and a modern consumer unit is a genuine improvement rather than a cosmetic one.
In Dargavel Village — the development built on the former Royal Ordnance Factory site, approved in outline by Renfrewshire Council in 2008, later expanded from 2,500 to 4,000 homes and still under construction — the reason is almost never age. Those boards are modern. What happens instead is that the household grows into the house: a garage circuit, a garden room, an extension, a workshop or a home office, and suddenly there are no spare ways left on the board. That's a capacity conversation, not a safety one, and we'll tell you plainly which of the two you're actually having.
The same sequence every time, whether it's a decades-old board in the original village or a capacity change in a newer home.

The supply is safely isolated and the existing circuits are inspected before anything is disconnected, so there are no surprises mid-job.

The old fuse board comes out and a modern consumer unit goes in, with improved circuit protection, better organisation and capacity for additional appliances.

Every circuit is tested once the new unit is live, and each one is clearly identified so you're not guessing which switch does what.

Certification is issued on completion, giving you a documented record for the property — useful for a sale, a letting or an insurer.
A consumer unit change is a small job with a disproportionate effect. It is the point where every circuit in the property is protected, controlled and labelled, so replacing a dated board improves how the whole installation behaves — not just the box on the wall.
For an older Bishopton property, the gain is mostly protection and compliance with modern standards. For a newer home, it's usually headroom: the ability to add the circuits you actually want without running out of space or overloading what's there. Either way, the work is quoted in writing first, and we'd rather leave a perfectly serviceable board alone than replace it for the sake of it.
From first enquiry to certification, usually inside a single working day on site.
Send your Bishopton postcode and, if you can, a photo of the board you currently have.
Inspection of the existing installation, with a clear explanation of what we find.
A written quotation and an agreed installation date before anything is ordered.
Professional installation — most jobs completed within one day, depending on the property.
Full system testing carried out and certification issued before we leave.
Based in Paisley and upgrading consumer units across Bishopton, the Renfrewshire villages and Greater Glasgow:
Most installations are completed within one day, depending on the property. We'll confirm the timing once we've seen the existing board and agreed the scope with you in advance.
Rarely as a safety upgrade, but it does come up as a capacity one. If you're adding a garage, garden room, extension or workshop circuit and the board has no spare ways left, it may need changing to take them. If there's room to work with, we'll tell you that and simply add the circuit instead.
Safe isolation of the supply, inspection of the existing circuits, removal of the old fuse board, installation of the modern consumer unit, full system testing and the issuing of certification. It's all set out in the written quote before work is booked.
Yes. A modern consumer unit is normally installed as part of a full or partial rewire, or as a standalone upgrade where the rest of the wiring is sound. If you're weighing up both, start with our house rewires in Bishopton page.
It's a common request ahead of a new tenancy or as part of wider landlord improvement works, particularly in older Bishopton properties. We can advise on what a specific property needs and coordinate the work around tenancy dates.
Yes. Every upgrade includes full system testing, and certification is issued on completion by qualified electricians, giving you a record for the property.
Older board that's had its day, or a newer home that's simply run out of ways — contact SJI Electrical and we'll inspect what's there before recommending anything.
