- New CEO and strengthening of leadership team
- Revenues soar six-fold from £10m to £60m
- Continuing international growth and expansion

Dr Adrian Williams, who has led the business for the last six years, will pass the baton of CEO to Leah McGimpsey and become an executive director. Following the recent appointment of three managing directors; Alex Campbell, Darroch Baker and most recently Alistair Davidson joining from Royal Haskoning, the leadership team is further strengthened by Dr Stuart Clough as chief client officer.
The APEM Group has seen a six-fold growth in revenue since a management buyout backed by private equity firm WestBridge in 2019.
APEM has grown from a small UK consultancy with revenue of £10m to a Group with revenue of £60m, employing over 600 staff at offices in UK, Europe, USA, and Australia.
Strong organic growth has been supplemented with the strategic acquisition of four specialist businesses – Woodrow, AQUAFACT, GoBe and Macro Works. As demand for end-to-end environmental consultancy continues to grow, developing innovative solutions enables APEM to help solve our client’s biggest environmental challenges, partnering with them to deliver a thriving shared natural environment.
