Frequently Asked Questions
Q1: How do I know if my electrical system needs an upgrade?
If your fuse board uses rewireable fuses or you experience frequent tripping, it’s time for an inspection. We’ll assess your system and recommend safe, cost-effective upgrades.
Q2: Can you upgrade part of a system without a full rewire?
Yes. We can upgrade only what’s necessary – such as distribution boards, lighting, or cabling — without replacing the entire installation.
Q3: Will my business need to close during the work?
Not necessarily. We plan works around your operational hours to minimise downtime and disruption.
Q4: Do upgrades come with certification?
Yes. Every upgrade is tested, verified, and issued with the appropriate NICEIC Electrical Installation Certificate or Minor Works Certificate.
Q5: Are electrical upgrades expensive?
They’re typically more cost-effective than reactive repairs and can lower long-term energy bills, especially when upgrading to LED or energy-efficient systems.
Q6: Can you help ensure compliance with insurers or regulations?
Absolutely. We upgrade installations to meet BS 7671 and insurance standards, helping clients maintain full compliance and peace of mind.
