Unique ranked amongst top 200 fastest growing UK manufacturers
Unique Window Systems’ continuing growth has earned it a place in a respected cross-industry league table. The Leicester-based fabricator of windows, doors and curtain walling for trade, commercial, industrial, new homes, BTR and PBSA sectors ranked 63rd in the Top 200 Manufacturing Growth Index 2025.
Compiled by Grant Thornton UK – a leading UK firm that provides audit, tax, and advisory services – the Top 200 Manufacturing Growth Index 2025 celebrates the fastest growing, privately owned manufacturing businesses across Great Britain.
It offers an insight into the performance of these companies and the impact they are having on innovation and the wider economy.
Manufacturers have been selected based not only on their private ownership but also the Compound Annual Growth Rate (CAGR) of their EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortisation) for 2023 and 2024.
They were also required to have a minimum EBITDA of £1 million in the latest accounting period, with publicly available accounts for the two years in question. Manufacturing (excluding food and drink) had to be their primary activity, with headquarters in the UK.
Unique’s listing comes as the business continues on a remarkable growth trajectory. Since 2020, the company has seen its turnover more than double, surging from £20.8 million to over £45 million.
During that same period, the company’s headcount has also grown by 50%, increasing from 200 to 300 people.
Unique puts these remarkable achievements down to a combination of factors. This includes a commitment to offering high quality products backed by equally high levels of service, the levels of responsiveness it can offer as a business that remains proudly family owned, and its genuinely entrepreneurial and can-do approach.
Commenting on the Top 200 Manufacturing Growth Index 2025 listing, Atul Patel, joint-Managing Director, at Unique said: “Unique’s exceptional growth results from careful governance and management, a desire for excellence in everything we do, and a genuine appreciation of our customers, our team and our supply partners.
“We are delighted to rank amongst the fastest growing 200 manufacturers across Great Britain and this recognition is especially poignant coming in our twentieth anniversary year. It highlights our track record to date and makes a clear statement about our future ambitions.
Nick Gillott, Head of Manufacturing and Industrials at Grant Thornton UK, added: “British manufacturing continues to be a beacon of best practice on a global stage. Despite significant market challenges, the sector has shown resilience, agility and adaptability.”
“It continues to contribute billions of pounds to the UK economy and support over two million jobs. It’s been a privilege to be involved in creating an index that celebrates those achievements,” he concluded.
