Beattie Passive, which created the UK’s first Passivhaus-certified build system, is set for administration after running into cashflow problems.

Work has stopped at the company’s 10,800 square metre factory after parent company Beattie Passive Group Ltd and four related companies filed notices of intention to appoint an administrator.

Bosses said despite boasting a strong order book worth £4.5m and achieving year-on-year revenue growth, the company had encountered a cash flow gap, which it blamed on delays to major projects.

The company uses precision engineering to make homes to Passivhaus standard at a factory in Norwich, which are then transported to their permanent locations.

The company has manufactured houses for a number of councils, including for flats in Swansea and for emergency housing for homeless people in Cardiff.

Ron Beattie, founder and managing director, commented: “Having explored all strategic options, it is with deep regret that we have today filed a Notice of Intention to appoint administrators and paused operations.

“My family and I founded this business 15 years ago to deliver the types of high-quality, energy-efficient homes our country so desperately needs, while creating highly-skilled, green jobs within the local communities we operate.

“I want to express my sincere thanks to all of those who have helped Beattie Passive become the pioneering company it is today, and we will continue to explore all possible options as part of our strategic review.”
