Broadband in Cardiff
Cardiff broadband from OCCTA starts with the address, not a city-wide promise. This page is for homes in places such as City centre, Cardiff Bay, Canton, and for postcode districts including CF10, CF11, CF14, CF24. The Bay and the student streets in Cathays should be checked as separate addresses. Price Lock 24 and Flex 30 are the plan styles OCCTA can offer where the address is eligible. The availability checker is what confirms technology, setup and the price for that door.

01Local guide
Cardiff areas and postcodes
Penarth and Barry are nearby. Use the town on the address, not a generic Cardiff search. Public speed bands go up to 1000Mbps only where that product is available, and the from-price of £34.99 a month is the national Price Lock 24 headline, not a Cardiff-only offer. If you are actually in Newport, Barry, Penarth, run the checker on that address rather than assuming this Cardiff page answers it.

03Questions
Broadband in Cardiff — FAQs
It is written around City centre, Cardiff Bay, Canton, Roath and districts such as CF10, CF11, CF14, CF24. Those names tell you the geography. They do not confirm that a particular building can take a particular product.
Both are national OCCTA options, offered only where the address is eligible. Price Lock 24 is a 24-month minimum term. Flex 30 is 30-day rolling with no fixed minimum term. In City centre you still need the checker, because eligibility is address-specific and the term, price, setup and any router charge are shown before you accept.
Newport is nearby, but it is not automatically the same check as Cardiff Bay or CF11. Enter the full Newport address in the availability checker. OCCTA will not treat a Cardiff page as proof that Newport can take the same technology.
Yes — OCCTA covers Cardiff via the access network available at the address. Enter your postcode to check availability.
Not necessarily. Flex 30 is 30-day rolling with no fixed minimum term where eligible. Price Lock 24 has a 24-month minimum term. Your exact term, price, technology, speed and charges are confirmed before acceptance.
