SJI Electrical provides professional consumer unit and fuse board upgrades — we're based in Paisley and cover Howwood, on the A737 between Johnstone and Lochwinnoch, along with the rest of Renfrewshire.
The consumer unit is the central control point of your property's electrical system, and an outdated board is one of the most common reasons homeowners get in touch.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.
The honest answer is that we can't tell you from here. What we can say is what generally prompts an upgrade: an older-style board still fitted, faults or frequent tripping, renovation work underway, a property being prepared for rental, additional circuits needed, or simply wanting better safety protection. If any of that sounds like your Howwood property, an inspection is quick and gives you a straight answer either way.
Four stages, all in the same visit, on a date agreed with you beforehand.

The supply is isolated safely and the circuits behind the board are checked before anything is disconnected.

The old board comes out once you've seen the inspection findings and agreed the plan.

A modern consumer unit goes in its place — better protection, more capacity, circuits clearly labelled.

The system is tested in full and your certification is issued before we leave.
Most installations are completed within one day, depending on the property — one agreed date, one visit out along the A737, and the property back to normal by the end of it. We'll confirm timing clearly when we quote.
Five stages, and you know where you stand at each one.
