Face the Numbers First

Before you change a single payment, sit down and write out exactly what you owe. Not a rough figure you carry around in your head — the real numbers. For each card, note the balance, the interest rate (the APR), and the minimum payment. You can find all of this on your statement or in your banking app.

It can be uncomfortable to see it all in one place, but this list is the most valuable thing you'll make this month. Debt thrives on vagueness. Once you know you owe £2,340 at 24.9% on one card and £890 at 19.9% on another, you can make decisions instead of guessing.

While you're there, check whether any of your cards are still being used for new spending. If so, that's the first thing to fix — more on that below.

Two Proven Ways to Attack the Debt

Once you've got your list, you need a system for deciding where each spare pound goes. There are two approaches that work well, and both involve paying the minimum on every card and then throwing everything extra at one target.

The avalanche method: put your extra cash towards the card with the highest interest rate first. This saves you the most money overall, because you're killing your most expensive debt before it racks up more interest. It's the mathematically smart choice, and over a year or two the difference can be hundreds of pounds.

The snowball method: put your extra cash towards the smallest balance first, regardless of interest rate. You'll clear a card quickly, which gives you a genuine psychological boost, and that momentum keeps a lot of people going when the avalanche approach might feel slow and thankless.

Neither is wrong. If you're the sort of person who needs to see a win to stay motivated, the snowball often beats the avalanche in practice, even if it costs a little more in interest. Pick one and commit.

Free Up Money You Didn't Know You Had

Extra payments have to come from somewhere. Rather than waiting for a pay rise, look for money that's already leaking out of your budget.

• Check your subscriptions. Streaming services, gym memberships, app subscriptions and cloud storage add up fast. Cancel anything you haven't used in the last month and redirect that money straight to your target card.
• Renew your insurance and broadband early. Loyalty rarely pays. A quick comparison before renewal often shaves £100–£300 a year off car, home and broadband bills.
• Look at your energy tariff. If you've been on a standard variable rate for a while, it's worth checking what's available. Even a modest saving each month is a debt payment in disguise.
• Sell what you don't use. That old phone, bike, games console or spare furniture can turn into a few hundred pounds. Send the proceeds straight to your card before it disappears into general spending.
• Trim the weekly shop. Meal planning, a shopping list, and switching a few branded items for own-brand can free up £20–£40 a week for a typical household.

Even £50 a month extra makes a real difference. On a £2,000 balance at 22% APR, adding £50 to a typical minimum payment can knock well over a year off your repayment time.

Stop New Borrowing and New Spending

You cannot outrun fresh spending. If you're paying £200 a month towards a card but putting £250 on it, you're going backwards no matter how clever your repayment strategy is.

A few practical steps help here:

• Remove saved card details from websites and apps, so buying something takes deliberate effort.
• Take the card out of your wallet and use debit or cash for day-to-day spending, keeping the card for the debt only.
• Set a monthly spending limit for each category — food, travel, entertainment — and check it weekly, not monthly.
• Pause major purchases for three months. Most "must-have" items look a lot less urgent after a fortnight.

Also think carefully before taking on new credit to pay off old credit. Balance transfers and consolidation loans can work, but only if you're confident you won't run the old cards back up. Otherwise you simply double the problem.

Make the Payment Automatic and Visible

Willpower is unreliable; systems are not. Set up a standing order or direct debit for your target payment on the day after payday. That way the money is gone before you've had a chance to spend it.

Then make your progress visible. Keep a simple note on your phone or fridge showing the balance on your target card, updated each month. Watching a number fall from £2,000 to £1,500 to £900 is remarkably motivating, and it turns an abstract worry into a project with an end date.

If you have a partner, share the plan. Two people rowing in the same direction clear debt far faster than one, and it removes the friction of surprise spending.

Consider Whether You Can Pay More, Even Temporarily

Sometimes the fastest route is a short, focused push. For three or six months, could you take on a bit of overtime, pick up a few weekend shifts, or do some freelance work? If you can earn an extra £200 a month and put all of it towards your highest-rate card, you could clear a serious chunk of debt in a single season.

Be realistic, though. A brutal budget you abandon after six weeks doesn't help anyone. A moderate plan you stick to for eighteen months will beat a punishing one every time.

The most important thing is to start. Pick your target card today, set up the payment, cancel one subscription, and let the balance begin to fall. Momentum builds quickly once the first payment lands — and the day you clear that final card is closer than it feels right now.
