Global leader in end-to-end sustainability solutions: providing clients with strategic advice and on the ground support, partnering with them in Making Sustainability Happen.


We provide an opportunity for great people to partner with great clients on environmental and other sustainability challenges in a collaborative, equal and entrepreneurial ‘One Team’ culture. We then seek to offer returns for our staff and shareholders over the long term, so that we all share in the success of our business.


“We founded the business in 1994. Since then, we have built ‘One Team’ of talented environmental and business consultants, engineers and scientists. We partner with clients throughout their project life-cycle from strategy and design, through compliance and operations, to end-of-life and remediation. Our ambition is to be recognised as the global leader in environmental and advisory solutions, helping our clients to achieve their sustainability goals.” Neil Penhall CEO


SLR has been advising clients for over 25 years at every point of their project life-cycle. Starting as a UK business, we now operate as a global company with more than 1800 people delivering client solutions across five regions. We have grown both organically and through welcoming other like-minded businesses with a similar ‘one team’ culture into the SLR group. We are ably supported by our principal investor, Charterhouse Capital Partners, and will continue to build a balanced, successful and growing business.
