To qualify for the Large Business of the Year Award, sponsored by Sleigh and Story, companies needed to be able to demonstrate significant growth in their sector, along with innovation.
Firms should have a plan mapped out for future developments and be able to show evidence of sound financial performance.
Peter Sleigh and Debbie Story presented the award to winners Severn Unival.
Severn Unival works with major international players in the oil and gas industry to develop specialist, highly engineered valves and valve management solutions.
In 2009, the firm set ambitious growth targets for the next five years.
As it approaches the end of that timeframe, the company can report an average growth rate of 12.5 per cent each year.
Host Clare Frisby said: “The judges were impressed with the business continuing to provide opportunities for more staff and apprentices since returning to Brighouse after 16 years to purpose-built premises.
“The reason behind the move was so it could foster greater efficency and technical advancement.
“Its new base is also home to the firm’s research and development team.”
Colin Findlay, of Severn Unival, said he was absolutely delighted.
“We work hard together as a team and hopefully we succeed as a team. That’s the way we like to do it,” he said.
“Brighouse is very much the centre of the valve industry in the country.
“There are several very good valve companies and we believe that we are the best.”
Also shortlisted was British Car Auctions.
The company has been bringing together buyers and sellers for more than 60 years.
It started by selling 14 cars and generated proceeds of £2,300.
Now the company sells more than 12,000 vehicles a week in physical auctions and over the internet.
It is part of BCA Europe and is the largest vehicle remarketing company.
