Sites of special scientific interest (SSSIs)

What is a Site of Special Scientific Interest?

Sites of Special Scientific Interest (SSSIs) give legal protection to the most important sites for wildlife, geology and landform in England and Wales. They are areas of land that Natural England or Natural Resources Wales designate as being of special interest because of their flora, fauna, geological or physiographical features, such as wetlands, rivers, meadows, beaches and peat bogs.

The owners of SSSIs are restricted in what they can do to and on the land and must manage the land so as not to cause any damage to it.

See Practice Note: Sites of special scientific interest (SSSIs).

DESNZ announces new measures for Warm Homes Plan

The Department for Energy Security and Net Zero (DESNZ) has announced new measures for its Warm Homes Plan, with the aim of upgrading 300,000 homes in 2025. These measures include increased funding for the Boiler Upgrade Scheme (BUS) to facilitate heat pump adoption and the amendment of existing permitted development rights to remove the one-meter planning rule for heat pump installations in England, enabling more households to install air source heat pumps without obtaining planning permission from early 2025. DESNZ also plans to consult on raising minimum energy efficiency standards for rented homes by 2030 and improving standards for new boilers and heat pumps. In addition, it will introduce a reformed Clean Heat Market Mechanism from 1 April 2025. DESNZ also announced a £1.29bn allocation for the Warm Homes: Social Housing Fund Wave 3 and a £500m allocation for the Warm Homes: Local Grant as part of the Autumn Budget. These funds will be distributed over three years, from 2025 to 2028. In addition, it announced changes to the BUS. Due to a surge in applications, the Secretary of State for Energy Security and Net Zero, Ed Miliband authorised an increase in the scheme's budget and granted Ofgem permission to over-allocate vouchers.

DLUHC launches consultation on Right to Buy reforms to protect social housing

The Department for Levelling Up, Housing and Communities (DLUHC) has launched an eight week consultation on proposed reforms to the Right to Buy scheme. Key measures under consideration include extending the minimum tenancy period for eligibility, exempting newly built social homes from the scheme and introducing targets for councils to replace sold stock. The government has already reduced maximum Right to Buy discounts to £16,000 - £38,000 and increased the cost floor protection period to 30 years. Councils can now retain all receipts from sales and the scheme will not be extended to housing associations. These reforms aim to create a more sustainable Right to Buy programme while protecting and increasing social housing stock amidst unprecedented housing pressures.
