LED Lighting ROI Calculator
Old lamps eat electricity and maintenance time. LED can pay back over sensible periods for many small sites—this guide keeps worked examples modest and flags what moves the result.

The LED Business Case
Well-chosen LED fittings usually use much less power than legacy halogen for the same job, and quality lamps often last longer—actual lifetimes and savings depend on hours, heating, and how hard the fitting is on the lamp. Payback might be well inside two years for simple lamp swaps in busy sites, or longer where usage is light; use our figures as worksheets, not guarantees. See also retail energy and office energy.
Real Example: Small Cafe
Current setup: 20× 50W halogen spotlights, 10 hours/day
Annual cost: 20 × 50W × 10h × 365 days = 3,650 kWh × 26p = £949/year
LED upgrade: 20× 7W LED bulbs = 511 kWh × 26p = £133/year
Illustration only: at an example 26p/kWh and steady hours, moving 20×50W halogens to efficient LEDs might save on the order of £200–£600 a year for many small cafés—swap costs vary with fitting type; payback could be from a few months to a couple of years once labour is included.
ROI Calculator
Annual Saving = (Old Wattage - New Wattage) × Hours/Day × 365 × £0.26 / 1000
Payback Months = Upgrade Cost / (Annual Saving / 12)
Priority Lighting
- Spotlights and downlights (halogen → LED): Fastest payback
- 24/7 lighting (emergency exits, security): Maximum savings
- High-ceiling bulbs (avoid frequent replacements)
