Homes improvement group sells minority stake

Homes improvement group Sustainable Investments has announced the sale of a 24 per cent stake to Bridges Fund Management.

The Group, based in Skelmersdale, said the investment will 'help accelerate its growth and expand its impact across housing and the wider built environment'.

Sustainable Investments operates across domestic green retrofit, energy services, building products and smart technology. Derek Horrocks will remain chairman and the majority shareholder, retaining overall control and continuing to lead the group alongside the existing business leadership teams.

The group, which recorded turnover of £70m in its 2025 accounts, comprises Sustainable Building Services, Sustainable Energy Services, Permarock and Sustainable Smart Technologies.

Derek Horrocks, chairman of Sustainable Investments, said: “The success of our businesses is down to our people and the trusted relationships we have built with our clients, customers and partners. From our family business roots, my ambition has been to build lasting businesses that provide worthwhile careers and make a positive difference to homes, lives and communities.

“Being sustainable means building businesses that people can rely on and giving our teams opportunities to develop. As we grow, we can improve more homes and buildings, help more households facing fuel poverty and support the skills and local businesses needed to keep making a difference over the long term.

“I have chosen Bridges because they share that ambition and the values behind it. They understand that commercial success and positive impact go hand in hand, and their experience, wider team and relationships will help us accelerate our growth and deliver my vision for the group. Our teams have built a strong business, and this partnership will help us extend the difference we can make even further.”

Bridges is a specialist sustainable and impact investor with more than two decades of experience.

Charlie Edwards, partner and cohead of inclusive growth at Bridges, will join the newly formed group board, led by Derek Horrocks. He brings extensive experience of supporting entrepreneurial businesses and will contribute directly to the group’s development alongside the wider Bridges team.

Charlie Edwards, partner and cohead of inclusive growth at Bridges, said: “We are delighted to be partnering with Sustainable Investments, a very impressive company that shares Bridges’ commitment to delivering exciting commercial growth in markets with high social impact.

"There is a clear opportunity for the group to scale its offering and expand its impact in the coming years, building on its outstanding work to date. I look forward to working closely with Derek and the rest of the team to support these ambitious growth plans, drawing on the broader Bridges team’s extensive experience of value creation and impact management.”

The group’s operating businesses retain their legal identities, brands, leadership, directors, management and operational teams. Existing contracts, service commitments and customer contacts remain unchanged as a result of the investment.
