An energy boss claims his company was overlooked in making Colchester United's new stadium eco-friendly - even though it sponsors the club.

Allan Berry, chief executive of Colchester-based Smart Energy, could not believe the business had not been contacted about plans to make the 10,000-seat ground more sustainable.

He said Smart Energy was even prepared to install free solar water heating systems, but its offer had not been taken up.

The Gazette previously reported that Colchester Council was considering green measures, which could push up the final cost of the stadium by £500,000.

They include a £250,000 wind turbine and rain stores for watering the pitch.

Councillors are due to discuss the proposals at their cabinet meeting next week.

Mr Berry said: "I cannot believe the council has the largest solar company in the UK on its doorstep and it doesn't even come to us for any advice.

"We would install the system for free. We would certainly not be talking the hundreds of thousands of pounds that they are at the council."

Mr Berry said he had spoken to Colchester United about solar power, and club officials had tried to help put him in touch with the council but with no success.

He added: "I don't blame Colchester United. They don't have much say in it as they will be leasing it off the council."

Brian Jarvis, councillor in charge of planning and regeneration, said officers would contact the company about the stadium and talk over its ideas.
