Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, what assessment her Department has made of the level of mobile signal coverage gaps in West Sussex.

Ofcom is responsible for reporting on mobile network coverage across the UK and their data provides Government with information on mobile coverage gaps.

Ofcom do not publish mobile coverage data on a regional basis such as for East Sussex and West Sussex. However, in their Connected Nations Annual Report 2025, published on 19 November 2025, it is reported that 1% of the East Grinstead and Uckfield constituency has no 4G geographic coverage from any operator.

10% of premises in this constituency have no 5G (combined standalone and non-standalone) outside from any mobile operator, 68% of premises in the constituency do not have standalone 5G outside from any mobile operator.
