A cross-party group of MPs are to question the chair of the Committee on Climate Change and the chief executive of the National Infrastructure Commission next week.

The business, energy and industrial strategy select committee will question Lord Deben and Philip Graham on 26 March as part of its energy efficiency inquiry.

The session will also hear from the CBI, the Mineral Wool Insulation Manufacturers Association (MIMA), Hermes Investment Management and the UK Green Building Council (UKGBC).

Committee on Climate Change chair Lord Deben is likely to face questions on the importance of energy efficiency in meeting carbon budgets, whether current targets need strengthening and how retrofitting and new builds can contribute to decarbonisation.

While Mr Graham, who heads up the National Infrastructure Commission, is set to be asked about the government’s policy on energy efficiency in the context of national infrastructure priorities, while the third panel will focus on energy efficiency in the commercial sector and links with productivity.

The inquiry is examining the government’s overall approach to delivering energy efficiency improvements to buildings and whether it is showing enough ambition in encouraging homeowners, businesses and landlords to upgrade.
