Published council-wide context for councils linked to Carmarthen, not a finding about the whole place or a property.
These records are published for councils linked to known active postcodes in this place. The councils cover a wider area: a listed designation is not a finding that it intersects this town or any property. The list may not be exhaustive. AQMAs are management designations, not measured pollution concentrations, property exposure or clean-air charging zones. Absence of a designation is not evidence of clean air. Great Britain only; Northern Ireland mapping is not included.

Broadband and mobile connectivity
Ofcom publishes these fixed-broadband, full-fibre take-up and mobile coverage profiles for named local and unitary authorities, rather than for town boundaries. They are shown as wider council-area context for Carmarthen; availability figures are provider predictions, not measurements at every address.
These highlights come from complete all-premises and residential broadband profiles, both published full-fibre take-up measures, the complete 2G, 3G, 4G, voice, 5G and standalone-5G network-count profiles, and the premises and grid-pixel counts used as the mobile basis. View every published broadband, full-fibre and mobile value.
