A RISK management firm in Huddersfield has sealed a takeover to keep it on course for expansion.
BES Group, based at Moldgreen, has bought asbestos inspection business E-Labs Environmental for an undisclosed sum.
BES is one of the largest consultancies of its kind in the UK - providing asbestos risk management services to thousands of small firms and major businesses.
Clients include Barclays, Argos, Dixons, Waitrose, HBOS and DHL.
E-Labs, based at Warrington, is an independent environmental consultancy specialising in asbestos inspection, sampling and testing.
E-Labs founder Helen Diane Bridge will remain as operations director following the takeover.
As part of the agreement, BES chairman John Lawrence will join the E-Labs board as director.
Mr Lawrence said: "The newly-acquired business gives us greater regional access to the high-growth asbestos risk management market.
"E-Labs has a strong brand and will be run as a stand-alone business in BES Group. The acquisition strengthens our ability to meet customers' needs across the north-west."
More than two years ago, BES was the subject of a £24.5m management buy-out backed by private equity firm LDC, which invested £6.9m for a significant minority shareholding.
Since then, BES has expanded its network of trained surveyors and analysts to provide coverage across the UK.
BES now employs almost 200 people and has offices in Cardiff, Birmingham, Edinburgh, Belfast, Surrey and Warrington. Turnover has risen to £8.7m from £2.8m in the past four years.
LDC director Carl Wormald said: "As awareness and enforcement of asbestos regulations increase, BES is seeing demand for its services continue to grow.
"The acquisition of E-Labs will enhance its reputation, technical abilities and further expands its geographical footprint.
"E-Labs will play a significant role in driving further growth."
The takeover was funded by Royal Bank of Scotland Corporate & Structured Finance, which also supported the BES buy-out.
More than 3m private and public properties in the UK are covered by the Control of Asbestos Regulations 2006 requiring "duty holders" in all commercial properties to ensure that people working or visiting there are protected from asbestos risk.
Only an estimated 10% to 15% have had adequate asbestos surveys performed - with even fewer implementing management plans to satisfy the regulations.
