SJI Electrical provides professional full and partial house rewires — we're based in Paisley and cover Howwood, on the A737 between Johnstone and Lochwinnoch, along with the rest of Renfrewshire.
We never recommend rewiring unnecessarily. Every project starts with a proper inspection and an honest assessment of what the property actually needs.
Three quick questions, then it goes straight to SJI on WhatsApp.
There's no shortcut to answering that. Howwood is a small village on the A737 corridor between Johnstone and Lochwinnoch, and anyone who tells you what your wiring is likely to be before they've looked at it is guessing. What is generally true of any property is that the age and condition of the existing installation decides the scope of the work: wiring that is over 25–30 years old, showing visible signs of deterioration, or tripping regularly is worth inspecting properly, and it's the inspection — not the address — that settles whether a partial rewire is enough or a full rewire makes better sense.
Not every property needs a full rewire — we inspect properly, then recommend the right solution.

New wiring throughout the property, a modern consumer unit, replacement sockets and switches, updated lighting circuits, then testing and certification.

Where only certain floors, circuits or previously-altered sections are outdated — often the practical answer within a wider renovation.

A modern consumer unit fitted as part of a rewire, or as a standalone upgrade to an older board.

Rewiring means accessing walls, ceilings and floorboards. Careful planning is what keeps that manageable, so we agree the schedule before we start and phase the circuits so the house stays usable wherever that's possible.

Based in Paisley and providing rewiring services across Renfrewshire and the wider Greater Glasgow area:
By having the installation inspected. Common prompts are wiring over 25–30 years old, visible deterioration, an outdated consumer unit, circuits tripping regularly, or a renovation being planned — but the inspection is what turns those signs into an answer.
No. In plenty of cases only certain circuits or previously-altered sections need attention. We advise honestly on whether a partial rewire is enough or a full rewire makes more sense long term.
It depends on the size, layout and condition of the property. After inspecting your home we agree a written timeline and schedule with you before any work begins.
In many cases, yes. We phase the circuits logically, maintain safe access, protect flooring and furnishings, and leave the property safe at the end of each working day.
Yes. Every rewire is inspected, tested and certified on completion, and carried out by qualified electricians.
