Anesco was named the UK’s fastest growing private business in 2013 by The Sunday Times Fast Track and has been recognised as one of the top cleantech firms in the world by the Global Cleantech 100 league table.
The company works with local authorities, businesses, housing associations and homeowners across the UK to reduce their carbon emissions, providing a turnkey service from audits through to recommendations, installations and capital funding plans.
The deal comes on the back of the Reading-based company reportedly beating targets to achieve turnover of £107 million and an EBIT of £10.8 million in the last financial year to March 31.
The senior team was also named BVCA venture capital-backed management team of the year in 2013 and again in 2014.
SEP Partners Gary Le Sueur and David Sneddon managed the investment in Anesco and the exit.
Calum Paterson, managing partner at SEP, said: ‘Since our first investment in 2011, Anesco has consistently delivered exceptionally strong growth.
‘We wish the company continued success in the future under its new ownership.’
