Founded in 2002 as a forestry business by brothers Jack and Shane Coombes (who give the company its name), Coombes branched out into vegetation clearance for the rail industry. Having worked with National Rail, the Petersfield-based firm was then awarded a contract to work on the HS2 project. Coombes offers a number of services for its clients such as: woodland creation, harvesting, biodiversity consultancy, and building management. In 2022, the company – still led by the Coombes brothers – had 57 employees, and a turnover of £45.1m, up from £11.3m in 2020.
