The RSK Group’s market profile received a boost in the 2007 ENDS Report Consultancy Guide where it gained considerable coverage and was listed as one of the UK’s six largest consultancies. Firmly ensconced in the £50m plus turnover category, RSK had the third most environmental contracts in the UK and the fourth most environmental contracts globally.

According to the guide, RSK's pure environmental consultancy capacity surpasses that of industry stalwarts such as ERM, Faber Maunsell and Entec.

Though the guide's ranking system differs from previous editions, RSK’s showing was far stronger than the 2006 showing where it featured in the £20-30m turnover bracket and was pegged as a ‘Top Ten’ consultancy in 6 out of 13 categories for work-area turnover and 4 out of 13 categories for client sector turnover.
