Common Questions

Consumer Unit Upgrade FAQs — Malmesbury

If your property still has an old fuse box with rewireable fuses, ceramic fuses, or outdated MCBs without RCD protection, an upgrade is strongly recommended. Modern BS7671 regulations require adequate protection, and many insurers and mortgage lenders now insist on a compliant consumer unit.
An RCD protects against electric shock by detecting earth leakage but does not protect against overload. An RCBO combines both RCD and MCB functions, protecting against shock, overload and short circuits on each individual circuit. RCBOs are the gold standard for modern consumer units.
A typical domestic consumer unit upgrade takes 4-8 hours depending on the number of circuits and condition of existing wiring. We usually complete the work in a single day and restore power before we leave.
Yes, the power will need to be off while we remove the old unit and install the new one. We work efficiently to minimise downtime, and most customers are without power for only a few hours. We can schedule the work at a convenient time for you.
Yes. Every consumer unit upgrade comes with a BS7671 Electrical Installation Certificate and a Building Regulations Compliance Certificate. These documents are essential for insurance, mortgage applications and property sales.
Absolutely. Modern consumer units with RCBO protection are a major selling point for estate agents and surveyors. They satisfy mortgage lender requirements, reduce insurance premiums, and give buyers confidence that the electrical system is safe and compliant.
We install premium brands including Hager, Schneider, MK and Wylex. These manufacturers offer excellent reliability, long warranties and clear, professional labelling. We recommend the best option for your property and budget.
Yes. We regularly upgrade consumer units in rental properties for landlords and letting agents. We provide all certificates required for compliance, work efficiently to minimise tenant disruption, and can schedule around tenancies.

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!”
