Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, if he will make it his policy to implement a replacement programme to intriduce LED lighting throughout buildings and sites used by (a) the Cabinet Office, (b) the Deputy Prime Minister's Office and (c) 10 Downing Street; if he will estimate the proportion of lighting in such sites which is LED; and if he will make a statement.

The Prime Minister’s Office and the Deputy Prime Ministers Office are integral parts of the Cabinet Office. The Cabinet Office estate is committed to improving the energy efficiency of its buildings. The estate incorporates buildings of different ages and types that require a selection of lighting solutions which must be assessed on a case by case basis. LED lighting does not always provide the most sustainable option in all scenarios.

Current implementation of LED lighting is approximately 5-10% across the entire estate. However, its use is increasing as existing lighting comes to the end of its effective life. Downing Street has implemented many of these new products in recent upgrades to some State Rooms, corridors and offices.

In addition to ensuring that the most appropriate lighting solution is selected across the estate, the Cabinet Office also incorporates lighting control mechanisms via presence detection and daylight sensors into its core buildings. These installations form part of the overall strategy to reduce electricity consumption estate wide as part of the wider Greening Government Commitment. Currently the estate as a whole has reduced electricity consumption by 34% from an 09/10 baseline
