SJI Electrical provides professional domestic electrical services — we're based in Paisley and cover Lochwinnoch, a drive south-west of us, along with the rest of Renfrewshire and the wider Greater Glasgow area.
Our focus is planned electrical work for homeowners and landlords rather than a high-volume call-out service, so every job starts with a proper look at what the property actually needs.
Three quick questions, then it goes straight to SJI on WhatsApp.
Lochwinnoch is a village in Renfrewshire that works largely as a dormitory settlement for Glasgow and Paisley, with a population of around 2,810 as of 2020. For a village of that size its layout is unusual: it was developed as a planned community from 1788, laid out with three grand vistas along straight streets, and it was designated a conservation area in 1972 in recognition of its architectural importance. A planned 18th-century core that has been protected ever since means a good deal of period property — and in period property the electrical installation is rarely the work of a single era, which is exactly why we look before we recommend.
Planned domestic work, carried out properly — not a high-volume call-out service.

New wiring throughout the property, or upgrades to specific circuits — inspected, tested and certified on completion.

EICR & landlord certificates →Lochwinnoch sits beside Castle Semple Loch within the Clyde Muirshiel Regional Park, with an RSPB nature reserve nearby and an unstaffed station on the Ayrshire Coast Line that has served the village since 1840. It is a place people commute out of, not one with a trade counter on every corner. We travel out from Paisley rather than working from a base in the village, and planned work suits that arrangement well: we can assess the whole property properly in one visit, put a quote in writing, and schedule the job for a date that works for you.
Clear communication from first contact through to certification.
Call, message or use the website form with your Lochwinnoch postcode and a short description of the work.
