SLR’s purpose is Making Sustainability Happen. We achieve this by having a team of expert advisors and technicians, who partner with our clients to tackle some of the world's most complex sustainability challenges, by utilising our collaborative and entrepreneurial One Team culture. SLR has been advising clients for over 30 years at every point of their project life-cycle. Starting as a UK business, we now operate as a global company with more than 4,400 people delivering client solutions across six 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, Ares Management, and will continue to build a balanced, successful and growing business. We’ve designed working life at SLR to look a little different. Because we know talented people often feel restricted by the rigid systems, lack of cross-functional collaboration and limited options for growth on offer elsewhere. Our One Team culture promotes meaningful professional and personal growth, our flat management structure provides many opportunities to progress, and our collaborative approach means you’ll get the chance to work on projects you care about and make a real difference. If you’re purpose-driven, self-motivated and keen to make an impact on a global scale, we want to hear from you.

Growth, as the source summarises it

SLR Consulting may be growing as evidenced by the expansion of their physical presence with the opening of new offices in London and Manchester, which suggests an increase in operational capacity and client base. The company has taken the top floor of a Northern Quarter office, indicating a significant spatial expansion to accommodate their team or services. These moves are indicative of a company scaling up its operations to meet a growing portfolio and possibly a larger workforce.
