Pros and cons

Capital One UK

Pros

  • Aimed at poor credit, so applicants turned down elsewhere can still apply.
  • Support runs on chat, phone and email, so help is easy to reach by phone, chat, email or a help centre.
  • Credit building tools come as standard: a free credit score and report, an eligibility check that leaves the credit score untouched, and round the clock fraud security.

Cons

  • Representative APR of 34.9% sits above the site average of 20.97%, so an unpaid balance costs quickly.
  • Foreign purchases are charged 2.75% in currency conversion, above the site average of 1%.
  • The rewards type is listed as none, so nothing comes back on everyday spending.

Santander UK

Pros

  • The balance transfer offer runs for 12, a clear window for moving and clearing an old balance.
  • One provider covers the current account, the debit card and the credit card, so the same bank handles the transfer.
  • Regulated in the UK by the Financial Conduct Authority, with Santander UK plc behind the accounts.

Cons

  • Currency conversion of 2.95% is the weak point, ranking 213 of 259 brands on that fee.
  • The rewards type is none, so nothing comes back on credit card spending.
  • An APR of 24.9% is steep, and with a rewards type of none there is nothing to offset a balance left over from month to month.

Who each suits

Capital One UK

Who it suits

  • UK applicants with poor credit who want a mainstream card rather than a secured one.
  • Balances being cleared, where the 18 transfer window and 3% fee on the balance transfer card keep the move contained.
  • Cardholders who pay in full and would rather build a score than chase rewards.

Who should look elsewhere

  • Not for frequent foreign spend, where Wise charges 0% on currency conversion against 2.75% on this card.
  • Not for anyone after a deposit backed card, since Varo Believe Secured Credit Card has an annual fee of $0 on a secured basis.
  • Not for shoppers who want a rewards earn on everyday buying, as the rewards type here is none and Chime Card (Secured Visa Credit Card) offers the same credit building route.

Santander UK

Who it suits

  • UK residents who want a current account and a credit card from one high street brand.
  • Anyone with an old balance to move across during the 12 transfer window.
  • People who pay the credit card in full each month and want an annual fee of £0.

Who should look elsewhere

  • Wise, if you spend abroad regularly: its currency conversion fee of 0.1% sits a long way under the 2.95% charged here.
  • Varo Believe Secured Credit Card, if you would rather build credit from a deposit, since it is a secured card with a monthly fee of $0.
  • Chime Card (Secured Visa Credit Card), if a US dollar secured card with a monthly fee of $0 suits you better than a UK current account.

Questions about each

Capital One UK

Is there an annual fee on the Capital One UK credit card?+

There is no annual fee. The card is sold on a no annual fee model, so the annual fee is £0 and the only real cost is interest. That interest is the part to watch, at a representative APR of 34.9%, because the card is aimed at poor credit and some applicants will revolve.

What rate applies if I do not clear the balance?+

The representative APR is 34.9%, above the site average of 20.97%. New purchases sit inside the interest free window the card offers, so the rate matters most once that window runs out or a transferred balance is still unpaid.

Santander UK

What does the Everyday current account cost each month?+

The account carries a monthly fee of £0, so holding it adds no regular charge to your bills. The card that comes with it is a debit card, so spending draws on money already in the account rather than adding to a balance. Keeping a small buffer there is the practical use.

How long is the balance transfer offer?+

The transfer offer runs for 12 and the balance transfer fee is 0%. That is the window for moving an existing balance from another card and paying it down. Start the transfer at the beginning of a billing period so the full window is available to you.
