SJI Electrical provides professional consumer unit and fuse board upgrades — based in Paisley, roughly five miles away, and working across Kilbarchan and central Renfrewshire.
The consumer unit is the central control point of your property's electrical system, and in a village with building stock this old it is often the first thing worth looking at.
Three quick questions, then it goes straight to SJI on WhatsApp.
Kilbarchan grew as a handloom-weaving village — over 800 looms were working here at the 1830s peak — and buildings of that age have usually seen several generations of electrical work by now. That is exactly the situation in which an older-style board is still sitting on the wall, quietly doing a job it was specified for decades ago. An upgrade also comes up for far more ordinary reasons: a renovation underway, additional circuits needed, a property being prepared for rental, or a board that has fallen behind current standards. If you're not sure whether yours needs replacing, we're happy to take a look and give you an honest answer either way.
Every upgrade follows the same structured process, from isolation through to certification.

The existing supply is safely isolated and the current circuits inspected before any work begins.

The existing fuse board is removed once the inspection and plan are agreed with you.

A modern consumer unit is installed, improving circuit protection, capacity and organisation.

Full system testing is carried out and certification issued once the upgrade is complete.
Most fuse board upgrade installations are completed within one day, depending on the property. In older Kilbarchan houses that qualifier matters: where an installation has been altered and added to over many years, the existing circuits need checking properly before anyone can say the board is a straight swap. That check is part of the inspection, and whatever it turns up is reflected in the written quote rather than sprung on you afterwards.
We ensure you understand every stage before work begins.
Send us the details of your Kilbarchan property and what's prompting the upgrade.
Inspection of the existing installation, with findings explained clearly.
A written quotation provided before anything is agreed.
An installation date agreed that works for you.
Professional installation, followed by testing and certification.
Based in Paisley and providing fuse board upgrades across Renfrewshire and the wider Greater Glasgow area:
Most installations are completed within one day, depending on the property. We'll confirm timing when we quote.
It can be. Where a property has been altered over many years, the existing circuits need checking properly before we can say what the upgrade involves. That check is part of the inspection and it's reflected in the written quote.
Common signs include an older-style board still fitted, electrical faults or frequent tripping, planned renovation work, or wanting improved safety protection. We can inspect and advise honestly.
The supply is safely isolated before any work begins, as it is for every upgrade. Full system testing is carried out before we hand the property back to you.
Yes. Every fuse board upgrade includes full system testing, and certification is issued once the work is complete.
We don't advise on planning matters — that isn't our trade, and we make no claims about work on listed or protected buildings. Where a property is older or sits within Kilbarchan Conservation Area, we establish the approach with you before any work starts.
If your Kilbarchan property still has an older-style fuse board, or you're preparing for renovation or a new tenancy, contact SJI Electrical to arrange an inspection. We'll look at the existing installation, explain what we find in plain terms, and give you a written quote before anything is agreed.
