Common questions
Before you call
How much does a rewire cost in Cornwall?
It depends on the size of the property, the condition of the existing installation and whether you are living there while we work. We survey the property and give you a written quote before anything starts.
Do I need a NICEIC registered electrician?
For most domestic work you need someone competent to self-certify under Part P of the Building Regulations, and NICEIC registration is how that competence is demonstrated. For commercial and industrial work it is what your insurer and your auditor will ask about.
How long does a house rewire take?
Five to ten working days for a typical three-bedroom house, depending on access and whether you are living there. Occupied rewires take longer because we work room by room and restore power each evening.
Why does my consumer unit keep tripping?
Usually a fault that only appears under load, which is why the board resets and then trips again later. Finding it means testing the circuits properly rather than looking for an obvious broken wire.
Can you install a three-phase supply for commercial premises?
We design and install three-phase LV systems, control panels, MCC panels and switchgear. The supply upgrade itself comes from the distribution network operator, and we handle everything from the incoming point onward.
Do you install CCTV and security systems?
Yes, as part of general electrical work rather than as a separate security contract. Cameras, external lighting and the power and data they need, installed and certificated alongside the rest of the electrical installation.
