BT43 broadband FAQs
Is the gigabit figure of 92% reliable for such a small postcode?
Yes. With only 558 postcodes covered, the sample is tight enough that aggregate figures are unlikely to hide major gaps.
What's the broadband outlook if I land outside gigabit coverage in BT43?
You'll almost certainly access superfast (30-300 Mbps). Only 1 in 10,000 postcodes fall below that tier.
How does BT43 fare for remote or rural premises within the postcode?
The data doesn't break down premises by settlement type. But a 0.1% below-10Mbps rate suggests even isolated addresses typically connect to modern infrastructure.
Would I need to negotiate broadband terms differently in BT43 versus nearby postcodes?
No. BT43's gigabit and superfast availability puts it in line with the rest of Mid and East Antrim's strong connectivity baseline.
