Attn SMEs: did you know you can get a 15% non-repayable contribution (up to £5,000) towards the cost of an LED retro-fit?

We specialise in the retro-fit of LED lights and lighting controls, and the provision of commercial LED lighting solutions for schools, offices and industrial premises. We can also assist organisations with emergency lighting compliance, and with the upgrade of emergency lighting systems to use self-testing luminaires, or central testing. 

The payback time for these upgrades is typically 2-4 years (slightly longer for schools).

We also have a finance option where the repayment of the initial investment is linked to metered savings from the lighting - please call us for more information.

This is what a recent customer (Bishops Court, Maidenhead) said about us on Google Reviews.

"A professional company who fulfilled their contractual obligation, in our case due to the age of our building there were a number of unforeseen issues. These issues were professionally absorbed by the company who amended the initial pre agreed plans to ensure that the end result was in compliance with regulation and our requirements. The Spirit Energy team installed the LED lights for our commercial building, which comprised of lighting on 4 interior floors including and the external private car park area. The entire team is professional, friendly and subject matter experts in each of their fields. We took quotes from a number of competitors, but this company stood head and shoulders above rest in terms of knowledge and price. Highly recommend."
