SJI Electrical provides professional domestic electrical services — based in Paisley and working across Renfrew, Renfrewshire and the wider Greater Glasgow area.
Our focus is planned electrical work for homeowners and landlords, not a high-volume call-out service — every job starts with a proper assessment of what your Renfrew property actually needs.
Three quick questions, then it goes straight to SJI on WhatsApp.
Renfrew's town centre stretches back to its days as a county town, with post-shipbuilding riverside development added as retail growth reshaped the area around it. That mix — long-established streets alongside newer housing — means the domestic electrical work we're asked to do in Renfrew varies property to property, and we approach each one on its own terms.
