Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, pursuant to the Answer of 19 December 2024 to Question 18950 on Planning Permission: Air Pollution, if he will make an estimate of the average additional cost resulting from that interim guidance for a new building dwelling in areas with poor air quality.

The interim planning guidance applies to developments which would normally require an air quality assessment, regardless of location and is expected to have minimal impact on the cost of new developments. As this is interim guidance an assessment of cost is not required.
