FAQs

Can you deliver an LED upgrade without a full re-wire?

Yes — LED swap-out using existing circuits is common where the existing wiring is sound (post-EICR). Typical ROI on energy savings is 2–4 years.

Do you handle DALI and wireless lighting controls?

Yes — we install Tridonic, Lutron, Casambi and Helvar systems, with commissioning and training for the FM team.

Will an LED upgrade help with MEES compliance?

Yes — lighting is typically the largest single electrical load in an office. An LED upgrade with controls can lift an EPC from D/E into B/C territory.

Do you test and certify emergency lighting?

Yes — annual full-duration discharge testing and monthly flick tests are offered under a PPM contract. Certificates to BS 5266 provided.
