LED lighting upgrades work in Gwynedd

Where ceilings in Gwynedd offices are being replaced anyway, we plan the new LED layout to BS EN 12464-1 rather than simply copying the old positions.

Most Gwynedd businesses we survey still have a mix of T8 battens, 600×600 fluorescent panels and the odd halogen downlight. Replacing them with complete LED luminaires usually cuts lighting energy by a third to a half.

What's included

A walk-round survey counting fittings, wattages, running hours and ceiling types
Complete LED luminaires rather than tube swaps, so old control gear is removed
Optional presence and daylight sensors to cut running hours further
Safe removal and recycling of old fluorescent tubes as hazardous waste

Rules that apply in Gwynedd

The Welsh Approved Document L Volume 2 (2022) uses 95 luminaire lumens per circuit-watt for general lighting, with alternatives such as LENI. A new Welsh edition takes effect from 4 March 2027 with a higher figure of more than 105.

In Great Britain, common T8 fluorescent tubes were caught by ecodesign rules from 1 September 2023 and the mercury exemptions for ordinary T5 and T8 lamps ended on 1 February 2024.

Privately rented commercial property in Wales generally needs an EPC of E or better, or a registered exemption, and lighting is one of the cheaper ways to improve a rating.
