Question to the Ministry of Housing, Communities and Local Government:

To ask His Majesty's Government what percentage of farmland is currently used by ground-mounted solar panels; and what estimate they have made of the percentage of farmland used by ground-mounted solar panels by 2050.

The government places great importance upon our agricultural land and food production. The National Planning Policy Framework is clear that planning policies and decisions should recognise the benefits of the Best and Most Versatile Agricultural Land (land in grades 1, 2 and 3a of the Agricultural Land Classification (ALC) system). Where significant development of agricultural land is demonstrated to be necessary, areas of poorer quality land should be preferred to those of a higher quality.

As of the end of September 2024, ground-mounted solar PV panels covered an estimated 21,200 hectares. This amounts to around 0.1% of the land area of the UK. The government does not hold information on the number of ground-mounted solar projects that have been permitted and built on different agricultural grades, or the number of acres of grade 1 and 2 land which has been built on since 2020.
