Installation FAQs

We are highly flexible. We frequently operate as a specialist sub-contractor for large construction firms and main contractors across NI. However, for specific electrical-only refurbishments (such as a retail lighting upgrade or server room fit-out), we happily act as the principal contractor, managing the project directly with the client.
Yes. We understand that shutting down a busy retail store or corporate office during the day is not an option. We regularly schedule installation works during evenings, nights, and weekends to ensure zero disruption to your daily operations.
Absolutely. As an NICEIC Approved Contractor, we provide a full Electrical Installation Certificate (EIC) or a Minor Electrical Installation Works Certificate (MEIWC) depending on the scope of the project. This is your legal proof that the new installation complies with BS7671.
