Jiselectrical Installation is the trading name of JIS ELECTRICAL LIMITED, and the business was set up to serve commercial clients rather than domestic call-outs. That focus shapes how we work: we plan around your trading hours, keep cable routes tidy through occupied buildings, and understand that a distribution board fault is not just an inconvenience, it is lost revenue.

The work we take on ranges from a single additional socket in an office to full rewires of workshops and retail units. We handle three-phase supplies, sub-main installations, emergency lighting, fire alarm cabling, and the containment that keeps everything tidy and compliant. If a job needs design input, we will sit down with your drawings or walk the site with you and work out the most practical route.

Because we work in buildings that are already in use, we are careful about how we sequence things. That means agreeing isolations in advance, keeping walkways clear, and cleaning up at the end of each day rather than leaving a trail of dust and offcuts. Most of our clients are busy people who want the electrics sorted with as little disruption as possible, and that is the standard we hold ourselves to.

Every job finishes with the paperwork your business needs. Test results, certificates, and clear notes on anything we have flagged are handed over in a format you can file away or pass to a landlord, insurer, or facilities manager. If something needs revisiting later, we would rather tell you now than have it become an emergency further down the line.

You can reach us through the contact page or by phone, and we will give you a straight answer on whether the work is something we can take on and when we can fit it in. There is no charge for asking, and no pressure to book on the spot. If we are not the right fit for a job, we will say so and point you towards someone who is.
