Thermal Storage Manufacturer Sunamp Honored With the First-Ever King’s Award for Enterprise

Sunamp is one of 148 organizations nationally to be recognized with a prestigious King’s Award for Enterprise. Announced last week, even as preparations are underway for the celebration of the coronation of King Charles III, these awards were previously bestowed by Queen Elizabeth II.

Employing 80 people and established 2005, Sunamp is a pioneer of innovative thermal storage solutions. From its base near Edinburgh, Sunamp designs and manufactures compact heat batteries based on its patented Plentigrade high performance thermal storage technology platform which works with almost any energy source to help to deliver highly effective, low-carbon heating and cooling in buildings. 

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.

“This award marks a milestone in Sunamp’s journey so far, from developing our game-changing phase change materials, to becoming world leaders in thermal storage technologies,” said Andrew Bissell, CEO, Sunamp. “The world struggled from 1947 to realize the heat battery vision of space-saving, easy to install and use, energy efficient storage for thermal energy. The lack of stable materials hampered efforts by large companies and prestigious Universities.”

Bissell further explained that Sunamp achieved the breakthrough in the early 2010s which enabled the company to arrive at the solution.

“Since 2018 we have brought this to market via four generations of heat battery products and so far we have delivered over 25,000 units. I am proud of everything we have achieved, and receiving a King’s Award recognizes everyone involved.”

The King’s Awards for Enterprise was previously known as The Queen’s Awards for Enterprise, and the new name reflects His Majesty The King’s desire to continue the legacy of HM Queen Elizabeth II’s by recognizing outstanding UK businesses.

The Award program, now in its 57th year, is the most prestigious business award in the country, with successful businesses able to use the esteemed King’s Awards Emblem for the next five years.

Benefits of winning this prestigious prize include invitations to a royal reception, presentation of the award at the company’s headquarters by one of The King’s representatives, a Lord-Lieutenant, permission to fly The King’s Awards flag, and use the emblem on marketing materials, an official Grant of Appointment, and a commemorative crystal trophy. 

Winners have reported benefiting from worldwide recognition, increased commercial value, greater press coverage and a boost to staff morale.

Applications for the King’s Award for Enterprise 2024 open on His Majesty The King’s Coronation, 6th May 2023.
