Broadband speeds in SA16

Share of SA16 premises by the fastest download speed available, averaged across all 259 postcodes in the district.

Superfast covers 90.4% of postcodes. Gigabit capacity is strong at 88%, matching the best-served Neath Port Talbot areas. Yet a puzzling contradiction emerges: 6.6% of SA16 postcodes fall below 10 Mbps despite 88% reaching gigabit, suggesting extreme postcode-level clustering. Speed distribution confirms this: 88% hit 300 Mbps or faster, 2.4% sit between 30 and 300 Mbps, and 6.6% lag far behind. Fixed wireless adds 4.2% coverage. This postcode likely contains a high-speed village or town centre alongside isolated rural postcodes with no infrastructure investment.

Living in Carmarthenshire

SA16's paradox reflects uneven rural deployment. City or town centre postcodes enjoy world-class gigabit, while scattered remote addresses remain untouched. Households should check individual postcode availability rather than assuming either extreme.

SA16 broadband FAQs

How can SA16 have 88% gigabit yet 6.6% below 10 Mbps?

Geography. SA16 likely contains a dense settlement or town centre alongside remote rural postcodes with zero infrastructure. Coverage is extremely postcode-dependent here.

Is my SA16 postcode likely to be gigabit or below 10 Mbps?

Odds are weighted toward gigabit (88% vs 6.6%), but always check your specific postcode. Rural-sounding addresses are at higher risk.

What happens if I'm in the 6.6% below 10 Mbps cluster?

You're in genuine broadband poverty and likely qualify for universal service obligation grants or targeted intervention schemes. Contact your provider and council.

Is there any fixed wireless coverage as an alternative?

Fixed wireless covers 4.2% modest but worth exploring if you're not scheduled for fibre soon.
