My Bank Kept Raising My Credit Limit

My first credit card had a limit of £1,200. Six years later, the limit was £8,000.

I never asked for a single increase. The bank offered every one.

Today the balance on that card is around £7,400. The limit is £8,000. I have never missed a payment. Not once, in six years. Every month, the minimum goes out on time. By the bank's records, I am a good customer.

The evening I compared two statements

One evening in March I sat down and did something I had been avoiding. I compared two statements, a year apart.

Twelve months of payments. Twelve months of never being late. And the balance had barely moved. Most of what I had paid had gone on interest and charges. The debt itself was nearly untouched.

For six years, the minimum payment had felt like proof I was coping. It went out on time. The bank never complained.

That evening was the first time I saw what the minimum actually was. Not progress. Maintenance.

It didn't need recklessness

That is the part worth sitting with. This story does not need recklessness to happen. It starts with a decision most people would call sensible.

Six years ago I applied for one credit card. The limit was £1,200. It was for emergencies. A car repair. A vet bill. The kind of month where the timing goes wrong. I used it carefully, and I paid it down, and for a while that was that.

Then the first letter arrived. It opened with the word congratulations. My credit limit had been increased to £2,500. I hadn't asked. I hadn't applied. The bank had looked at my account and decided, on its own, that I could be trusted with more.

It felt good. Being trusted usually does. I didn't use the new room. Not at first.

But life kept arriving. Christmas went on the card one year. The boiler went another year. Then there was a stretch where the card quietly became the buffer, the gap between the pay packet and the month. Not big purchases. Just drift.

And every so often, another letter came. £4,000. £5,500. £6,800. £8,000. Five increases in six years. I never requested one of them.

The room felt like relief

Here is the strange part. By the time the later increases arrived, I was carrying a real balance. And each new limit didn't feel like temptation. It felt like relief. More space between the number I owed and the ceiling above it. Breathing room.

But breathing room on a credit card is not free. Earlier this year, the average advertised rate on a UK credit card reached 35.8 per cent. The highest since records began in 2006. Every pound of that room I used was borrowed at that kind of rate.

Room like that is not really room. It just looks like it, for a while.

What the increases were actually based on

I assumed the bank kept raising my limit because I was doing well. Because someone, somewhere, had checked.

First, the scale. There are around 37 million active credit card accounts in the UK. Between them, they carry about £66.5 billion. My statement is one drop in that.

And within those millions of accounts, the regulator has a name for what happened to me. Persistent debt. The definition is precise: over eighteen months, you pay more in interest, fees and charges than you repay of the actual debt.

That is it. Not missing payments. Not defaulting. Paying, reliably, in a way that mostly feeds the interest.

In the regulator's most recent survey, 2.8 million adults in the UK were in persistent credit card debt. One in twenty. And that number was slightly higher than two years before.

I have met that definition for more than three years. While being, on paper, an ideal customer.

The part I didn't know

Before the rules changed, the regulator reviewed the evidence on credit limits. The research it relied on found something uncomfortable. When a credit limit goes up, the debt tends to rise with it. Roughly 10 to 14 per cent of the new room becomes new borrowing. And the effect holds whether the customer asked for the increase or not. It is strongest for people already close to their limit.

The debt follows the ceiling. Whether you asked or not.

My limit did not rise five times because I was doing well. And it did not rise because I was careless. My bank never said why. But the evidence is clear about what usually happens next. The ceiling moves, and for most people, the balance quietly moves up after it.

The regulator saw that evidence. It is part of the reason the rules changed in 2018.

The protections that already existed

Those rules are real, and they exist right now.

Since 2018, credit card customers have been able to opt out of automatic credit limit increases. Anyone in persistent debt for twelve months is not offered an increase at all. When the rules came in, the regulator expected that protection alone to keep offers away from around 1.4 million accounts a year.

And if you stay in persistent debt, the bank is required to contact you. At eighteen months. At twenty seven months. And at thirty six months it has to offer you a realistic way to repay faster. If you can't afford that, it has to consider reducing, waiving or cancelling interest and charges.

I had been a customer for six years. I knew none of this existed.

Nobody hid it from me. But nobody made it feel necessary, either. The letters that mattered always opened with congratulations.

What you are feeling is a mechanism

So if your own limit has been climbing on its own, and the balance has climbed with it, this is the thing to hold onto. What you are feeling is not a personal failing. It is a mechanism, working the way the evidence said it would. A ceiling that rises on its own is easy to stop noticing. Most people do.

Which leaves one question. The ceiling has always been the bank's number. What's yours?

One move

Contact your bank, by phone or in the app, and ask to opt out of automatic credit limit increases. That option has existed since 2018.

This doesn't repay anything. It doesn't need to. The drift needed a moving ceiling. From today, the ceiling only moves if you ask.

And if the balance underneath feels heavy, you don't have to work it out alone. MoneyHelper is free, confidential and backed by the government. Their debt advice locator can connect you with real help, online, by phone, or face to face.

I made the call on a Tuesday lunch break. The opt out took four minutes. The balance is still there. But for the first time in six years, the ceiling is mine.
