AGG Electrical Safety Testing Limited, a Mansfield-based provider of electrical safety testing and facility management services, has been sold to Rose Street Partners, a private investment firm.
Starting in 2006, brothers Andy and Gavin Griffiths established AGG to provide cost-effective and hassle-free Portable Appliance Testing (PAT) for local businesses and schools. Just a few years later, the company moved into offering full property maintenance services, and in 2018, it expanded to provide nationwide coverage by employing engineers across the UK.
The sale was the culmination of a collaborative effort, with Gavin and Andy Griffiths receiving guidance from local firms Mitchells Chartered Accountants & Business Advisers and CMP Legal.
Mitchells Chartered Accountants & Business Advisers, who had a long-standing relationship with AGG, initiated the process by helping Gavin and Andy explore potential exit strategies.
“Choosing the right team for this journey was crucial,” said Gavin and Andy Griffiths. “The collaboration between Mitchells and CMP Legal made what could have been a stressful process incredibly smooth. Their combined expertise and coordinated effort meant we could focus on our business, knowing the transaction was in safe hands.”
Andrew McDaid, partner at Mitchells, said: “Having worked with Gavin and Andy for years, it was a pleasure to guide them through this significant milestone. Their success is a reflection of the hard work they’ve put into building AGG.”
Anna Cattee, a co-founder of CMP Legal who heads the Company and Commercial Department, said: “We were delighted to work with the team at Mitchells and the Griffiths to ensure the legal aspects of this transaction were handled efficiently. The strong communication between all parties was key to delivering a positive result for everyone involved.”
Unlike traditional private equity firms that operate on a fixed time horizon, Rose Street Partners is structured to be a permanent home for enduring businesses, focusing on a “forever” time horizon.
“We are thrilled to welcome AGG into our family of companies,” said Daniel Skyte from Rose Street Partners. “Andy and Gavin have built a phenomenal business with a strong reputation for excellence and a commitment to its customers. Their dedication to quality and service is exactly what we look for in our partners.
“Our long-term approach means we are not just acquiring a company; we are becoming a custodian of its legacy and a partner in its future growth. We look forward to supporting the AGG team as they continue to serve clients and expand their services.”
A multi-disciplinary team from Freeths provided legal advice to Rose Street Partners. Corporate partner Francis Dalton said: “We are delighted to have supported Rose Street Partners on this acquisition. AGG is a well-established business with a strong growth trajectory, and this deal reflects RSP’s thoughtful approach to investing in businesses with long-term potential. It was a pleasure to work with the RSP team and help bring this transaction to a successful close.”
