Asset and energy support services provider Lakehouse has appointed Sean Birrane as its new chief executive amid a wider senior management reshuffle and new boardroom hires.

The moves follow a period of strong growth and a series of strategic acquisitions, including air and water hygiene specialist H2O Nationwide in October 2014 and Scottish energy services group Everwarm in April 2014.

Sean was previously managing director at Lakehouse, a role he has held since 2008. Having started his career with Lakehouse in 1996, Sean has seen the company grow to over 1,250 employees, with a regional presence now extending into Scotland.

Former chief executive and majority shareholder Steve Rawlings will remain a member of the board. Steve founded Lakehouse in 1988, having started in the industry as an apprentice roofer. He will now dedicate more time to Building Lives, the award-winning social enterprise which he founded in 2010 and focuses on supporting young people on the path to a career in construction.

Alongside a number of additional moves and hires in the senior team, the appointment of Sean as chief executive complements the rationalisation of the business into four key divisions: regeneration, construction, compliance and energy services.

Jeremy Simpson joins as chief financial officer from waste management business Shanks Group plc, where he was UK finance director before becoming group corporate development director. Jeremy brings a wealth of experience in the built environment, having worked across infrastructure, renewable energy and a range of large-scale, long-term local authority projects.

Simon Howell has been appointed as group company secretary following four years as group company secretary and head of legal at May Gurney, the construction and support services business now part of the Kier Group.

Former financial director Alan Cox moves into a new role as group corporate development director, having played an instrumental role in the company’s growth in the last six years. His new position will focus on consolidating Lakehouse’s new group structure and guiding the integration of recent acquisitions K&T Heating, Allied Protection, Foster Property Maintenance, Everwarm and H2O Nationwide.

Michael McMahon joins the board as managing director of Everwarm, the business he set up in 2011. The deal to bring Everwarm into the Lakehouse Group significantly boosted the company’s sustainability capacity, drawing on Everwarm’s expertise working in Scotland, where the retrofit market is more developed. Carol Bailey and Dean Ball become managing directors of Lakehouse’s regeneration and construction divisions respectively.

Former pre-construction director Phil Tidmarsh becomes group commercial director. Phil will be responsible for all commercial matters across Lakehouse and its subsidiary companies, ensuring consistent delivery through pre-contract to post-contract processes and developing Group-wide best practice procedures.

Stuart Black, executive chairman at Lakehouse, said: “It is great news that Sean is taking up the role of chief executive – his long history in the industry coupled with his unwavering commitment to Lakehouse makes him the best candidate for the job. Sean will benefit from the support of Jeremy, Michael and Simon, who are fantastic new additions to a first-class team, and will work together to continue to strengthen our business as the economy recovers.”

Sean Birrane, chief executive at Lakehouse, said: “Having seen Lakehouse change and grow during my time here, I am excited to take on this role as we consolidate the progress we have achieved both organically and through strategic acquisitions. Lakehouse is going from strength to strength, but we can continue to build on our superb record in construction and regeneration, as well as diversifying and enhancing our margins further in compliance and energy services. Developing and refining our business through these four key divisions has helped clients to better understand our offer and gives our business clear direction.”
