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 £1MILLION from the latest accounting period and accounts for the two years in question that were publicly available.
“We are delighted to rank amongst the fastest growing 200 manufacturers across Great Britain…”
Atul Patel, joint-Managing Director, Unique
In addition, it was essential that manufacturing (excluding food and drink manufacturing) was their primary activity and that their headquarters were 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 £20.8MILLION to over £45MILLION.
During that same period, the company’s headcount has also grown by 50%, increasing from 200 to 300 people.
“British manufacturing continues to be a beacon of best practice on a global stage.”
Nick Gillott, Head of Manufacturing and Industrials, Grant Thornton UK
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 is a result of careful governance and management, a desire for excellence in everything we do, and a genuine appreciation of the importance 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 demonstrated resilience, agility and adaptability. It continues to contribute billions of pounds to the UK economy and to support over two million jobs.
“It’s been a privilege to be involved in the creation of an index that celebrates those achievements.’’
