SJI Electrical provides professional consumer unit and fuse board upgrades — based in Paisley, 9.3 miles from Langbank, and working across the village, the rest of Renfrewshire and the wider Greater Glasgow area.
The consumer unit is the central control point of your property's electrical system. An outdated board is one of the most common reasons homeowners get in touch.
Three quick questions, then it goes straight to SJI on WhatsApp.
Langbank is a village of around 870 people that grew into a Glasgow dormitory settlement after the railway arrived in 1841. There's no published record of its housing stock beyond that, so the honest position is simple: we don't know what board is on your wall until we look at it, and neither does anyone else quoting you sight unseen.
The signs that a board may need replacing are the same everywhere, and they're worth checking whether the property is a family home or a let. If any of these sound familiar, we're happy to take a look and give you a straight answer either way.
Every upgrade follows the same structured process, from safe 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. That suits a village job well: one arranged visit, one day on site, and the property handed back tested and certified. We'll confirm timing clearly when we quote so you know what to expect.
Getting to Langbank is straightforward — it sits on the A8 a few hundred yards from the start of the M8, so a single-day job 9.3 miles from base is entirely practical to schedule.
We make sure you understand every stage before work begins.
