Centrica conducted a strategic review and concluded that first and foremost a customer-facing energy and services company. Therefore, from April 2016 British Gas will no longer operate through the three businesses British Gas Residential, British Gas Services and British Gas Business. The company will create two new Business Units (BUs), UK Home and UK Business, having already created a similar structure in North America.

These UK BUs will operate mainly under the British Gas brand. In response to the growing demand for innovative offerings in both segments, newly formed Connected Home and Distributed Energy & Power units will also sell through UK Home and UK Business to residential and business customers. The UK Home BU will be very significant in scale, with over 22 million customer accounts.

It will be led by Sarwjit Sambhi who has been at Centrica for nearly 15 years in a variety of roles including in Group strategy, Power Generation, and most recently as Managing Director of Exploration and Production (E&P) business. He has a deep knowledge of the energy sector and a passion for taking customer-facing businesses to the next level of performance. The new UK Home BU is key to the Group's success.

Establishing the new unit will require strong leadership, a strong focus on the customer and on the efficiency of operations, and management of change across a large number of dimensions. Sarwjit has an excellent track record of leading such change, and is able to lead the UK Home business into its next phase. Sarwjit will report to Mark Hodges, Group Executive Director and Chief Executive, Energy Supply & Services, UK and Ireland.

Following Sarwjit's appointment to UK Home, E&P will be led by Chris Cox who joins Centrica from BG Group where, until early 2015, he was EVP BG Advance responsible for all technical functions, capital projects, well delivery, IT and reserves. A Petroleum Engineer, he brings over 30 years' experience in the global oil and gas business which also includes North Sea operating roles at Chevron and Amerada Hess. In challenging times for the E&P industry, Chris is well-placed to lead the transformation of the business to a scale and strength which is optimal for Centrica, in line with strategy announced last year.

Chris will join the Centrica Executive Committee and report to Mark Hanafin, Group Executive Director and Chief Executive, Energy Production, Trading & Distributed Energy. In this role Charles will oversee Centrica's approach to both technology development and engineering; including assessing technology pipeline, product development and partnerships and ensuring the company have the right capabilities and resource allocation. Charles joins from BP where he was head of Research and Technology for BP's downstream businesses.

Charles is a member of Centrica's Executive Committee and reports to Iain Conn, Group Chief Executive.
