Sampson was previously chief press officer at 10 Downing Street. In her new role she will lead the press, public affairs and events teams at Energy UK, and will report to chief executive Lawrence Slade.
Slade said: “I am absolutely delighted that Abbie is joining Energy UK. Not only does she bring a wealth of experience and professionalism as a communications leader but her appointment strengthens our commitment towards consumers.
“An unprecedented number of firms are now competing for customers. Energy companies are investing many billions of pounds in renewing and decarbonising the power sector. Abbie will bring a sharper edge to our communications about how consumers, communities and the economy benefit from reliable, low carbon and affordable energy.”
Sampson added: “It’s a really exciting time to be joining Energy UK. The energy market affects every single person in the country and the challenges and opportunities facing the industry are well known.
“I’m looking forward to leading the communications team at Energy UK and working with the members and our stakeholders to ensure there is a proper, well informed debate about how the energy industry is changing and its vital contribution to the UK.”
Energy UK is the trade association for the energy generations and supply industry.
