The short answer
In England and Wales, privately rented commercial property in scope of the Minimum Energy Efficiency Standards generally needs an EPC of E or better, or a valid registered exemption. Lighting is one of the cheaper ways to improve a non-domestic EPC, because efficient LED and controls reduce the modelled energy use.
Why lighting matters for EPCs
Non-domestic EPCs model the building's energy use, and lighting is a significant part of it in offices, shops and warehouses. Replacing fluorescent or metal halide with LED, and adding presence and daylight controls, can move the rating.
The rules by nation
| Nation | Position |
|---|---|
| England and Wales | In-scope lets generally need EPC E or a registered exemption; government has said it intends to tighten this, subject to legislation |
| Scotland | Separate Section 63 regime: action plans for certain buildings over 1,000 m² on sale or new let |
| Northern Ireland | Own EPC framework, without the England and Wales EPC E letting rule |
Planning upgrades
- Get an assessor's view on which measures move the rating most.
- Use void periods between tenancies for lighting work.
- Keep certificates and schedules to support the new EPC.
Questions
Will LED alone get us from F to E?
Sometimes, particularly in lighting-heavy buildings, but it depends on the building. An EPC assessor can model the options.
