What kind of sites get cited
This is what AI links to as its sources, which is not the same as the brands it names above. AI often recommends a provider by name but sends the citation to a publisher or affiliate instead, so “First-party brand” means a link to the provider’s own website. Here is the mix by engine.

The themes behind the recommendations
Looking past the brand names, these are the concepts and buyer intent the AI answers kept returning to for this product. Each finding starts with what the engines foreground, then what it means for you.
UK credit card answers are dominated by the 0% balance transfer. This is a borrowing-cost category, not a rewards-chasing one like the US.
The 0% balance transfer is the headline
Answers lead with the length of the interest-free balance transfer period. The AI ranks cards on how long you avoid interest, so the longest clean 0% offer is the biggest driver of a mention.
Borrowing cost over rewards
Unlike the US, the framing is managing debt rather than earning points, with rewards cards a secondary group. Buyers are steered to cost of borrowing, which rewards clear transfer-fee and term messaging.
Transfer fees are the tie-breaker
The models weigh the balance transfer fee against the interest-free length. A long 0% with a high fee is treated cautiously, so transparent fee information helps a card rank.
