Credit cards get a bad reputation, and in some cases that's deserved. In my late teens I was irresponsible with credit - store cards, credit cards, a loan - and ended up on a debt management plan for five to six years clearing it all. That was 22 years ago now, and it taught me more about money management than anything else ever has.

Since my late twenties I've used credit cards completely differently - as a tool that works in my favour rather than against me. Right now I use a Tesco Clubcard credit card for everyday spending, collect points on everything we buy, and exchange those points for Pizza Express vouchers at three times their value. We get a couple of free meals out each year purely from spending money we'd have spent anyway. We pay the balance in full every month and have never paid a penny in interest.

That's what a credit card can be when you use it well. Here's how.

Understand how credit cards actually work

When you spend on a credit card, you're borrowing money from the card provider for a short period. At the end of each billing cycle you receive a statement showing what you owe. You can either pay the full balance, a minimum payment, or anything in between.

If you pay the full balance every month, you pay zero interest. The card provider makes their money from the merchant fees on each transaction, not from you. This is why using a credit card for normal budgeted spending - and paying it off in full - is genuinely free money management.

If you don't pay in full, interest is charged on the remaining balance at the card's annual rate, which can be high. This is where credit cards become expensive. Understanding how to properly manage your budget throughout the month is essential if you want to use a credit card without ever paying interest.

Use a rewards or cashback credit card for everyday spending

One of the smartest ways to use a credit card is to put your normal, budgeted spending on a rewards card and pay it off in full every month. You're spending money you'd have spent anyway - on food, petrol, bills - but earning points or cashback on every transaction.

We use the Tesco Clubcard credit card for exactly this. Every pound we spend adds to our Clubcard balance, and we exchange those points for Pizza Express vouchers at three times their face value. It's one of the best value exchanges available through Clubcard - £5 of points becomes £15 of vouchers - and over a year of normal household spending we typically earn enough for two, or three, free meals out. It costs us nothing because we always clear the balance.

There are cashback cards and rewards cards tied to other retailers, airlines, or straight cash back. The key is finding one that matches where you already spend. There are also great UK cashback sites and apps that can be used alongside a cashback credit card to double up on rewards.

The one discipline this requires: track your spending. I check our credit card balance every day to make sure we're staying within our monthly budget. It takes a couple of minutes but means we never overspend just because we're using a card rather than cash. Done carelessly, rewards cards cost more in interest than they ever earn in points.

Use a 0% credit card to spread the cost of a large purchase

If you need to make a significant purchase and want to spread the cost without paying interest, a 0% purchase credit card is a genuinely useful financial tool - provided you use it deliberately and pay it off within the interest-free period.

I've done this before for larger costs where I wanted to manage cash flow rather than clear a lump sum immediately. The important things to get right are:

• Know exactly when the 0% period ends - set a reminder well in advance
• Divide the balance by the number of months in the 0% period and set up a direct debit for that amount
• Clear the full balance before the promotional period ends, or transfer it to another 0% card if needed (there may be a charge for transferring to another card)
• Don't use the card for additional spending unless that's also within the 0% terms

The mistake people make is treating the 0% period as free money indefinitely. It isn't - it's deferred interest. If you don't clear it in time, the rate reverts to the standard APR which can be significantly higher. Smart money management techniques make the difference between a 0% card being a useful tool or an expensive trap.

Take advantage of Section 75 protection

One of the most underused benefits of paying by credit card is Section 75 of the Consumer Credit Act. If you pay for something between £100 and £30,000 on a credit card and the seller fails to deliver, goes bust, or sends you something fraudulent, your credit card company is jointly liable with the seller. You can claim a refund from them directly.

I haven't needed to make a claim personally yet, but I've used the threat of it effectively. When a car hire company abroad failed to return our deposit after we'd returned home to the UK and stopped responding to emails, mentioning Section 75 and that I was prepared to raise a dispute with my card provider prompted them to respond and process the refund within days.

A friend of mine received a counterfeit product from an online seller and couldn't get any response from the company. She went to her credit card provider instead and got a full refund through a chargeback. That kind of protection simply doesn't exist with debit cards or bank transfers in the same way.

For any purchase over £100 - particularly from unfamiliar retailers, online shops, or for travel deposits - paying by credit card rather than debit card adds a meaningful layer of protection. This pairs well with knowing your consumer rights and how to deal with financial disputes.

Use a credit card for hotel and car hire deposits

When you check into a hotel or pick up a hire car, the company often places a holding amount on your card as a deposit - sometimes several hundred pounds. This is released when you check out or return the vehicle, but it can take several days to clear.

If that holding amount is taken from your debit card, it comes straight out of your available balance and can cause problems if you need that money for other things while you're away. On a credit card, it sits within your credit limit and doesn't touch your regular bank account at all. When it's released, it simply disappears from your statement.

We always use a credit card for hotel check-ins and car hire for exactly this reason. It's a practical use of credit that costs nothing if you pay the balance in full when your statement arrives. It's also worth knowing how to save money when you travel abroad to make the most of every trip.

Always pay in full if you can - and set up a direct debit

The golden rule of credit card use is pay in full every month. This is the only way to use a credit card completely for free. Everything else - rewards, protection, convenience - is a bonus on top of that.

If paying in full isn't possible every month, at least pay more than the minimum payment. Minimum payments are designed to keep you in debt for as long as possible. The interest charged on a typical credit card balance far outweighs any rewards you might have earned.

Set up a direct debit for the full statement balance each month so it pays automatically. This removes the risk of forgetting and incurring a late payment fee, which damages your credit score as well as costing money. If you're ever in a position where you genuinely can't clear the full balance, it's worth looking at low-risk ways to invest or grow spare money to build a buffer so you're never caught short.

Build and protect your credit score

Using a credit card responsibly - spending within your means and paying on time - is one of the most effective ways to build a good credit score. Each on-time payment is recorded positively. A strong credit score makes it easier to get mortgages, loans, and better interest rates further down the line.

The things that damage your credit score fastest are missed payments, maxing out your credit limit, and applying for multiple cards in a short period. Keep your utilisation low - ideally below 30% of your available credit limit - and avoid applying for new credit unless you genuinely need it. Understanding what goes into your credit score and how to improve it is worth doing before you apply for any new financial product.

Know the warning signs that a credit card is becoming a problem

Credit cards can be an excellent financial tool - but only if you have the willpower and discipline to use them within your means. If you find yourself:

• Regularly only paying the minimum
• Using a credit card because you've run out of money rather than as a deliberate choice
• Avoiding looking at the balance
• Taking cash advances on a credit card

...those are warning signs that the card is working against you rather than for you.

I know what that feels like from my own experience in my late teens. The shift from using credit irresponsibly to using it as a deliberate tool took time and a lot of hard lessons. If you're in a difficult position with credit card debt right now, what to do when you have debt you cannot pay is a good starting point, and organisations like StepChange and Citizens' Advice offer free confidential advice.

Is a credit card right for you?

A credit card is a good tool if you can genuinely commit to paying it off in full each month, or using a 0% deal deliberately with a clear repayment plan. The rewards and protection benefits are real and meaningful. The cost of using one carelessly - in interest, in credit score damage, in stress - is also real.

Used well, a credit card gives you free rewards on spending you'd have done anyway, meaningful consumer protection, and flexibility for travel and large purchases. That's a genuine benefit. The discipline required to get there is worth developing - I've been using them responsibly for over 15 years now and the points alone have paid for more than a few nice evenings out.
