The business, which trades as AFECO and employs around 30 staff, has been operating for 10 years.

AFECO develops and delivers mechanical, electrical, instrumentation, control and automation services and solutions related to water, wastewater and biosolids treatment, in addition to energy generation and expert consultancy.

AFECO will sit in United Living’s Infrastructure Services business alongside the group’s existing water activities.

The firm, which was acquired by private equity giant Apollo last August, is on the acquisition trail after reporting revenue up 22% to £534m in the year to March 2023.

United Living Group chairman Neil Armstrong said: “AFECO has an outstanding reputation in the water industry for innovation and problem-solving.

“This acquisition will complement our existing activities and help extend our service offering to include mechanical, electrical controls and automation.

“We are looking forward to working closely with AFECO’s management team to unlock further potential on behalf of our combined customers.”

Abi Field, chief executive officer of AFECO said: “We are delighted to join forces with United Living, enabling us to better provide unique solutions for the water sector.

“This comes at an opportune moment, particularly as we help our clients navigate increasing pressure on their operations. We believe that our highly innovative products are a great addition to United Living Infrastructure Service’s offerings and that together we will be able to meet our clients’ evolving needs.”
