Firm named in North West Fastest 50 for third year running

Skelmersdale-based Sustainable Investments Ltd has been named among the fastest-growing companies in the North West at the 2026 North West Fastest 50 Awards, marking its third consecutive year on the prestigious list and its fourth appearance overall.

The group comprises Sustainable Building Services (UK) Ltd (SBS), Sustainable Energy Services (UK) Ltd (SES), Sustainable Smart Technologies (SST) and Permarock Products Ltd.

Derek Horrocks, chair of Sustainable Investments Ltd, said: "Making the Fastest 50 for a third year in a row is a milestone that means a huge amount to everyone across the group. Growth like this doesn't happen by accident. It's built on the dedication and expertise of our teams and a shared commitment to delivering positive change.

"With our retrofit schemes delivered by SBS, retrofit consultancy from SES, the data-led services of SST or Permarock's trusted energy efficiency products, each brand plays a vital part in delivering real social value, alleviating fuel poverty, improving homes and buildings, and supporting the UK's net zero transition. We strive to make a real positive difference to people's lives and we're looking forward to continuing this mission as the group enters its next phase of growth."

The Fastest 50 list is compiled annually by law firm Ward Hadaway, in partnership with the Greater Manchester Chamber of Commerce. It celebrates the region's top-performing, privately-owned companies based on average turnover growth over the past three years while remaining profitable. The 2026 final rankings were revealed during a special event in Manchester on Friday 10 July, bringing together the region's most successful business leaders.

Liz Bottrill, executive partner in Ward Hadaway’s Manchester office, said: “I extend my congratulations to Sustainable Investments and all of the businesses recognised in this year’s North West Fastest 50. Every company on the list has earned its place by growing consistently and profitably, often in conditions where progress has required careful decisions and real resilience."
