In the July 2014 cabinet reshuffle she was appointed parliamentary under secretary of state for climate change at the Department of Energy and Climate Change in July 2014  inheriting the same portfolio as had been held by Greg Barker as minister of state.
Rudd's move from the Treasury and role as an ally of George Osborne was viewed as a sign that the Treasury was seeking to tighten its grip on green energy spending. Rudd's new responsibilities include the embattled Green Deal and other energy efficiency schemes such as the Energy Company Obligation, which is in the process of being overhauled. 
She is the sister Roland Rudd, founder of PR firm Finsbury PR and the treasurer of the Britain Stronger in Europe campaign in the UK's membership referendum of 2016. The 'In campaign' was also firmly backed by Theresa May, the new Conservative prime minister. 
Tamasin Cave, of Spinwatch and the Alliance for Lobbying Transparency, said:
