Thomas Howell
Business Manager

Thomas is a career recruiter with 20 years’ experience working across the Technical recruitment industry. Most of his working life has been spent overseas working on international assignments in industries such as Construction, Energy, Rail and Mining. His current role with ESC involves developing relationships with new clients which allows him a free rein to speak with people across the Energy industry in any given location.

After spending fifteen years in Asia he is back to where it all started in (supposedly sunny) Hove, he is enjoying the ability to enter a new market and apply recruitment and business development techniques to a rapidly expanding renewable energy industry. Fortunately, the team at ESC are true experts in their specializations and more than willing to share knowledge with colleagues and clients. With an emphasis on quality and customer service ESC are not your typical recruitment partner which is a breath of fresh air compared to some “churn and burn” companies who purely manage people using strict KPI’S.

Thomas is married with three kids and spends his time thinking about all the things he used to do when he wasn’t married with three kids.
