Commercial FAQs

Do you work with commercial landlords and facilities managers?
Yes — a large part of our work is commercial. We work with landlords, letting agents, facilities managers and shopfitters across Lancashire, and we're set up for planned maintenance as well as one-off projects.
Can you work out of hours to avoid disrupting our business?
Yes. For offices, retail and occupied units we regularly work evenings and weekends so the premises stay usable during trading hours. We'll agree the programme with you up front.
What is fixed wire testing and how often do we need it?
Fixed wire testing (a commercial EICR) is the periodic inspection of your installation. Most commercial premises need it every five years, and many insurers and landlords ask for it more often. You get an itemised report with any remedials priced up front.
Are you qualified and accredited?
Yes — J P Slater Electrical is a NAPIT-approved and Safe Trader electrical contractor, fully insured and certified to the latest (18th Edition) wiring regulations.
Do you offer emergency call-outs?
Yes — we offer a 24-hour emergency electrical call-out and maintenance service across Preston and Lancashire. Call us and we'll help as quickly as we can.

“Jonny came and fitted an EV charger for me. The cable work was super tidy, making sure the wiring was hidden around the walls of the house. He even came round on his weekend off to have it ready for my vehicle's delivery. Great lad and top professional.”
Matt FinnVerified Google review
“Replaced my old consumer unit with a modern RCD consumer unit. The install was completed in good time with minimal disruption. I'll be more than happy to call J P Slater Electrical for any future work.”
