Benchmark International is pleased to announce the acquisition of Carlisle-based AndiDrain by Glasgow-headquartered Denholm Energy.
Established in 1990, AndiDrain is a liquid waste management and industrial services company offering a range of services such as tankering, CCTV pipework surveys, waste segregation and recycling, sewer/culvert renovation, and relining.
Denholm is an international services provider supplying leading edge services across industry sectors including oil and gas, marine, defence, petrochemical, renewables, utilities, and distilleries. Employing over 4,500 people, the company has operations in the UK, USA, Caspian, and Middle East and has an annual turnover in excess of £190m.
The move by Denholm Energy's subsidiary, Denholm Environmental Services, further strengthens Denholm’s waste management and industrial services offering. It also expands the geographic footprint of Denholm Environmental from the Scottish Highlands down to the Midlands and adds a comprehensive and market leading range of equipment to the portfolio.

Andrew Little, managing director of AndiDrain, said this about working with Benchmark International:
“I would like to thank Roger, James, Charlotte, Nick and the rest of the team for a job well done with the sale of the company. I can highly recommend Benchmark to anyone who requires a M&A specialist to guide them through what can be difficult times when dealing with due diligence.”
