RSK Group is a privately held UK-based environmental, engineering and technical services group, comprising over 175 companies employing some 10,500 people and with turnover of £1.22bn in 2023.

History

RSK Group was established in 1989 in Aberdeen by Alan Ryder, [2] and has grown both organically and through an accelerating programme of acquisitions. [3] Today based in Helsby in Cheshire, it aims to become Europe's largest privately owned environmental and engineering business with a £1 billion turnover and employing 10,000 people worldwide by 2025. [3] RSK has acquired over 70 businesses in six years from 2016. [4]

In the year to April 2021, RSK's turnover reached £350.5m, up from £274.8m the previous year, and made a pre-tax loss of £18.9m, having made interest payments to backers of £22.8m. [4] In the year to April 2022, RSK made a fifth consecutive pre-tax loss, of £38.1m, on a turnover of £796m inflated due to its dozens of acquisitions. It made £39.9m in interest payments. [5]

In August 2023, RSK announced plans to raise £500m from sales of shares in the business. Supplementing around £500m from Ares Management, this would provide £1bn to fund further acquisitions. It aimed to raise headcount to 40,000 by 2030, expanding internationally in Australia, Europe, Asia, Latin America, Africa and the Middle East. [6]

In the year to April 2023, RSK grew its revenues over 50%, to £1.22bn. Pre-tax losses doubled to £81m, after £74m in interest payments. Founder and CEO Ryder said the group was on track to achieve £5bn revenue by 2030. By March 2024, having completed 24 further acquisitions, RSK employed 10,530 staff. [1]

Acquisitions

Following a number of early acquisitions including Structural Soils (2007), [7] Dynamic Sampling and JB Site Investigations (both 2016), [8] RSK Group made its first large acquisition with ADAS in late 2016. [9] ADAS was the UK's largest independent provider of agricultural and environmental consultancy services, bringing with it a then 300-strong workforce that made the RSK Group one of the largest environmental consultancies in the UK in 2016. [10]

In May 2017, the company acquired Acies Civil and Structural, followed in June by the acquisition of KMGP Ltd. In December, RSK completed a trio of deals, acquiring C.J. Associates Geotechnical Ltd, Up and Under Group Ltd and all outstanding (80%) shares of RSKW Ltd.

In August 2021, RSK agreed the largest private credit backed, sustainability-linked financing deal on the market to date with Ares European Direct Lending serving as sole lenders of £1 billion available debt facilities to boost the growth of the business. [29] The new debt facilities include an annual margin review based on the achievement of sustainability targets, which are broadly focused on carbon intensity reduction and continual improvement to health and safety management and ethics. [30] RSK anticipates interest savings in excess of £500,000 per year and has committed to donate a minimum of 50% of this margin benefit toward sustainability-related initiatives or charitable causes. [30]
