Question to the Department for Transport:

To ask the Secretary of State for Transport, how many new build developments have included roads which have not been adopted by local authorities due to not meeting minimum standards in each of the last five years.

The Department does not hold this information as we do not collect data about un-adopted roads. A local highway authority may adopt a road if it has been built to the required standard. It will then become maintainable at the public’s expense. An authority will not, however, adopt a road that does not meet the required standard. Some developers do not seek adoption, and some residents will prefer to keep the road as private.
