A MACMERRY business has celebrated being honoured by the King.

Staff at Sunamp marked their success at a Highland games-themed event at Whitekirk Hill, with fun activities including caber tossing and tug-of-war.

At the gathering, Sunamp co-founders Andrew Bissell and Susan Lang-Bissell were formally presented with the King’s Award for Enterprise and a scroll by Roderick Urquhart, Lord-Lieutenant of East Lothian, on behalf of King Charles III.

Sunamp was one of only 148 companies out of the 572 UK applicants to be named a winner of the 2023 King’s Award for Enterprise in April. It was one of only 11 in Scotland.

Set up in 2005, the business designs and manufactures thermal-energy storage solutions that make homes, buildings and vehicles more energy-efficient and sustainable.

Sunamp’s Thermino range can store energy from renewable sources to deliver hot water in thermal batteries that are up to four times smaller than equivalent hot water cylinders.

The heat batteries are designed to store and release thermal energy on demand, significantly improving energy efficiency and reducing carbon emissions.

Andrew Bissell, Sunamp’s CEO, said: “We are thrilled to receive the King’s Award, and to gather team members from around the world to join us in East Lothian to celebrate has made it more special. This recognition means the world to us and is a huge testament to our team’s dedication and hard work.

“Our goal has always been to revolutionise how we use and store heat, making it easier for everyone to embrace renewable energy.

“There’s no reason why every home shouldn’t have a heat battery in the future.

“We can all make a positive impact on the environment and help drive the shift towards a greener, more sustainable world.”
