In December 2018, RSK acquired tree surgeons, bts Group. The company is a leading tree and vegetation management business providing arboricultural support for major utility companies across the UK, such as UK Power Networks, by keeping vegetation and trees under control and within legislation-driven standards. The company also offers commercial vegetation management and tree surgery to public and private customers, including councils, private estates, construction firms and homeowners. BTS joined RSK’s agriculture, land and property management division and strengthened RSK’s existing arboricultural consultancy and vegetation management services and internal supply chain.
