Our qualified in-house electricians bring years of expertise and industry-leading credentials to every project, including 18th edition, Level 3 NVQ, City and Guilds 2391, and City and Guilds 2377 qualifications. What’s more, we never use subcontractors, guaranteeing a consistent, high-quality service tailored to your specific needs.



What Are Rewires?
Rewires involve replacing the wiring, circuits and associated components within a property’s electrical system to ensure they meet modern safety and efficiency standards. Over time, electrical installations can deteriorate or become outdated, posing significant risks such as electrical fires or equipment failures. Comprehensive rewiring addresses these issues, ensuring your property complies with current regulations and is safe for use.
In addition to full rewires, we also offer partial rewiring for specific areas or circuits, providing a cost-effective solution for targeted electrical upgrades. Whether you need a complete overhaul or focused improvements, we’re equipped to handle the job as Plymouth’s trusted local electrician.
When Are Rewires Necessary?
There are several situations where rewires might be required, including:
- Age of the Property: Homes and commercial properties around Plymouth built over 30 years ago often have wiring that doesn’t meet modern standards.
- Frequent Electrical Issues: Signs such as blown fuses, tripping circuits or flickering lights may indicate underlying faults.
- Renovations or Extensions: Adding new rooms or upgrading existing ones often requires a system-wide electrical upgrade.
- Failed Inspections: If electrical safety checks identify major issues, rewires might be the best solution.
- Visual Signs of Deterioration: Cracked sockets, exposed wiring or outdated fuse boxes are clear indicators full or partial rewiring is worth considering.
If you’re unsure about the state of your property’s wiring, our fault-finding service can help identify any underlying issues and recommend the best course of action.
