Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what estimate he has made of the (a) electricity cost of perimeter floodlighting of military bases and (b) potential cost saving of moving to LED or other energy efficient bulbs for such floodlighting.

Energy usage of perimeter floodlighting of military bases is not metered separately and no estimate of costs are held.

The Ministry of Defence (MOD) is committed to improving energy efficiency across the defence estate in line with the Net Zero ambition. Energy efficient lighting is one aspect of this and there is a proactive programme to transition to LED lighting. However, as MOD is not able to baseline the cost of perimeter floodlighting, potential cost savings cannot be provided.
