SJI Electrical installs and upgrades consumer units for homes across Linwood — based in Paisley and covering the whole of Renfrewshire.
The consumer unit is the central control point of your property's electrical system. If it's outdated or undersized, we'll explain exactly why an upgrade matters before any work begins.
We never recommend an upgrade that isn't needed — every job starts with a proper inspection first.
Three quick questions, then it goes straight to SJI on WhatsApp.
Linwood's housing runs from council-era properties built up around the town's former car plant to more recently built homes further out — and older-style fuse boards turn up in both. The consumer unit is the central control point of a property's electrical system, and it's usually one of the first things worth checking.
We're based in Paisley, around three miles away, so getting out to assess a Linwood property doesn't mean a long wait for an appointment.
Every upgrade follows the same careful process, whatever the property:

Safe isolation of supply, followed by a proper inspection of the existing circuits.

The old fuse board is removed and a modern consumer unit installed in its place.
