Energy consumption comparison
- T5/T8 fluorescent: 60–90 W/m² office
- Basic LED: 25–40 W/m²
- LED with controls: 8–18 W/m²
- Target: 6–12 W/m² for new fit-outs 2026
Typical ROI calculation
For a 10,000 sqft office:
- Baseline energy cost (fluorescent): £22,000/yr lighting
- Post-LED cost: £7,500/yr
- Annual saving: £14,500
- Retrofit cost: £45,000–£75,000 (swap-out) / £90,000–£150,000 (full scheme with controls)
- Payback: 3.1–5.2 years (swap) / 6.2–10.3 years (full)
Add DALI controls for additional 20–30% saving on top.
Non-energy benefits
