Philip Dennis Foodservice Turned Their Roof Into £2,400,000

In 2024, Spirit Energy installed 1,636 solar panels for Phillip Dennis Foodservice Ltd in Oxfordshire. The system is expected to save over £85,000 in the first year, should pay for itself in under four years, and save over £2,400,000 on electricity bills over 25 years. 

Businesses in a similar situation to Phillip Dennis Foodservice are wasting over £7,000 per month on electricity bills.
