What to expect from one of our Historic Property Lighting Reviews

The creation of a full asset list detailing all of your lighting applications by type and location. The best option to replace each light will be recommended along with the following key information necessary to review which improvements should be prioritised:

1. The cost to replace it
2. The expected lifetime of that product
3. The breakeven point (when the savings pay for the light)
4. The estimated total savings that it will make over its lifetime, and
5. Its impact on the environment

Illustration of indicative energy saving

The following estimations are based on 8 hours a day, 5 days a week for 50 weeks a year with an electricity cost of 15p/kWhr.

* - made up from electricity savings, cost to replace failed old lamps, time to change lamps and a reduced CO₂ levy
