Remortgage Reminder
Santander UKRecorded a lower monthly payment than the renewal quote.
How 0% promotional periods end, when interest starts, and why timing matters before the standard rate takes over.
Promotional risk
Interest starts
MoneyHelper says if you still owe anything when a 0% period ends, you will pay expensive interest.
Minimum repayment rule
Keep the deal
MoneyHelper says you must repay at least the monthly minimum or the 0% deal could end.
Interest-bearing balances
47.6%
UK Finance says 47.6% of outstanding credit card balances incurred interest in December 2025.
Balance growth
8.9%
UK Finance says outstanding balances on credit card accounts grew by 8.9% over the twelve months to December 2025.
0% scope
New spending only
Which says 0% purchase deals apply only to eligible new spending and not necessarily to other card uses.
A 0% card is one of the clearest Onremind categories because the pricing changes on a known date.
The card works one way during the promotional period and a very different way once it ends. If the balance has not been cleared or properly planned for, the standard rate can start applying immediately.
That makes the end date the real event. The risk is not the card existing. It is letting the promotional period end before the plan is ready.
0% cards are useful because they create breathing room. That can also make them easy to leave until later.
The spending happens, the promotional period keeps running, the monthly minimum gets paid, and the bigger review keeps slipping. Then the 0% period ends and the standard rate takes over.
That is why this is a timing category. The important question is not whether the card was useful. It is whether the review happened before the interest started.
Know when the promotional rate stops.
The amount still outstanding changes the right next step.
Understand the post-promo cost, not just the 0% benefit.
A 0% card only stays useful if the next step is deliberate.
Once the date passes, the cost basis changes.
