LONDON, UK, April 11th, 2024: Cap10 portfolio company Sureserve Group (“Sureserve”), the leading compliance and renewable energy services group, has announced that it has acquired 100% of Duality Group (“Duality”).

The acquisition includes Duality’s subsidiaries (i.e., Gas Call Services Ltd, WRB Gas (Contracts) Ltd, and Dyson Energy Services Limited) which focus on delivering renewable energy and heating solutions to the social housing sector and residential clients across Scotland and England.

Duality was established in 2016 and grew to £56M in revenues and made three acquisitions (Dyson in 2016, Gas Call in 2018 and WRB in 2021). The acquisition of Duality will not only expand Sureserve’s geographic coverage but also enhance the breadth and quality of services the group is able to deliver.

This announcement represents Sureserve’s second acquisition in less than a year since it was acquired by Cap10 in July 2023. Sureserve acquired Swale Heating in November 2023, which expanded Sureserve’s heating capabilities and service solutions in England.

Cap10 explains that this acquisition is a great step forward to help Sureserve deliver its core heating solutions and renewable energy services across the UK to a broad set of customers while continuing to play a key role in the decarbonisation of the UK’s social housing. When Cap10 acquired Sureserve, Founding Partner Fabrice Nottin said that the firm would strategically invest in the business to enable it to achieve its full potential, with today’s announcement further embodying that clear vision and a well-defined investment strategy.

The deal will enable Sureserve to expand its heating solution service offering in Scotland, where Duality mainly operates, while remaining aligned with Sureserve’s mission: to be the trusted partner of choice to the social housing and related public sector in delivering essential and affordable heating, energy savings, and compliance solutions.

Fabrice Nottin continues: “We’re delighted to welcome the Duality’s team within the Sureserve Group family. We would like to congratulate Graham Levinsohn and his team on completing a second strategic acquisition for Sureserve in less than six months. The acquisition of Duality further delivers on our growth strategy for Sureserve. The two companies complement each other perfectly and will deliver Sureserve an expanded reach into Scotland while enabling an increased offer through the transferring of skills and services.”
