Commercial Rewiring Services for Offices, Shops & Warehouses in Wiltshire

Commercial rewiring requires careful planning to avoid disrupting your business operations. Invisiwire provides professional commercial rewiring across Wiltshire for offices, retail units, warehouses and restaurants, with flexible scheduling that keeps your business running throughout the project.

We understand that closing your business for rewiring is not always an option. Our team works evenings, weekends and in phased sections to complete the work without stopping your operations. Every rewire is planned around your trading hours, staff schedules and customer needs.

Our commercial rewiring service covers everything from first fix cabling and back boxes to second fix sockets, switches, light fittings and consumer units. We test every circuit thoroughly and provide full BS7671 certification on completion for your insurance and compliance records.

From small office refits to large warehouse rewires, we have the experience and equipment to handle commercial properties of all sizes. We serve businesses throughout Devizes, Calne, Melksham, Chippenham, Trowbridge and all Wiltshire commercial areas.

Common Questions

Commercial Rewiring FAQs — Keep Your Business Running

A small office may take 3-5 days. A large warehouse or multi-unit building can take several weeks. We provide a detailed timeline before starting and work efficiently to complete each phase on schedule.
Yes. Commercial rewiring is one of our most common out-of-hours services. We regularly work evenings, nights and weekends to avoid disrupting business operations, particularly for retail and hospitality clients.
We minimise damage by careful routing and use existing access points where possible. Some making-good may be needed after first fix, which we can discuss during planning. We always leave work areas clean and tidy.

Customer Reviews

What Our Wiltshire Clients Say

Real reviews from real customers. Rated five stars on Google and Facebook by homeowners and businesses across Wiltshire and Somerset.

“I had Lewis and his team out to do the electrics on a new extension I was having. Not only did he deal directly with the builder so I didn't have to manage anything, he listened to what I wanted rather than telling me what I had to have. They were fast, efficient and tidy — I cannot recommend them highly enough!”
