Aliter Capital-backed engineering group Edwin James Holdings (EJH) has bolted-on Peterborough Electrical & Mechanical Engineering (PEME).

Founded in 1982, PEME offers maintenance services for electrical and mechanical plants to manufacturers across the UK and Europe. The business employs around 200 people.

The acquisition brings EJH’s combined revenues to around £150m (€168.5m) and headcount to approximately 1,000, up from £37.5m and 360 employees when Aliter first made its investment. The value of the transaction was not disclosed.

PEME is the second bolt-on EJH has made under Aliter’s watch. In April, EJH acquired Midlands-based WT Parker Group which provides mechanical, electrical and process engineering services.

Aliter picked up EJH in January and plans to pursue bolt-on acquisitions. The majority investment came as the firm closed its first fund at its hard cap of £92m.

The private equity house was founded in 2016 by support services entrepreneurs and investors Billy Allan, Greig Brown, Andy Galloway and Andrew Busby. Aliter makes majority equity investments of up to £20m per company across the UK.
