Have you had a credit card, store card or catalogue where your credit limit was too high? So high that the monthly repayments were hard to manage and you got into more debt?
For some people the limit was too high at the start. Others were originally given an OK limit, but the lender kept increasing it. or it was OK while the 0% offer lasted, then unmanageable.
You may have a good affordability complaint that the lender was irresponsible in allowing you to borrow so much.
This applies even if you made every payment on time, as you may have borrowed more elsewhere.
This article explains how to ask for a refund of the interest you have paid.

What is “affordable”?
The regulator’s rules
Even if you made every payment on time, the debt may still have been unaffordable.
The following is my summary of the regulator’s rules:
- a lender must check if credit is affordable when you apply for it. For a very low limit, not many checks are needed;
- a lender should make similar checks before increasing a credit limit;
- credit isn’t affordable if paying it leaves you short of money for your bills, normal expenses, and your other debts;
- if you have to borrow more most months, this would not be affordable;
- you must be able to repay the limit set within a reasonable period. Paying the minimum amount is OK for a while, but not for a long time.
Good reasons to complain
If the lender could see any of these on your credit record, they should probably have declined your original application:
- a level of borrowing that looks very high in relation to your income; or
- you had a different credit card with the same lender where you were only making minimum payments; or
- other credit cards where you were near your limit and persistent overdraft usage. Here is an Ombudsman decision saying Zopa should not have given quite a low initial limit in this situation; or
- recent credit record problems: defaults, missed payments, or arrangements to pay, mortgage arrears; or
- recent payday loans or a lot of recent credit applications.
Your credit limit should not have been increased unless you could afford it. In addition to the points above, any of the following should have also warned the lender you were already in difficulty:
- making minimum payments for a long while;
- often taking cash out on the card;
- making a minimum repayment but then using the card to pay for food or petrol so the balance never drops;
- using most of your limit for a long period;
- significant gambling the lender was aware of;
- recent missed payments or an arrangement to pay on your credit record;
- your overall level of debt on your credit record had increased a lot.
NB many cases are won when someone has never missed a payment.
You don’t need to know the dates and amounts of any limit increases before you start your complaint – my template asks for these.
0% balance transfers
Here the lender should check that you would be able to repay the whole limit within a manageable length of time (say 5 or 6 years) taking into account that interest will be charged when the 0% term ends.
So if you were ok during the 0% term but then you couldn’t afford the payments when interest started being added, you can complain. Ask for any interest to be refunded and to be able to repay the rest with no interest. Don’t make a complaint about a BT that is still at 0%, it’s much easier to wait until the 0% has ended.
Do I need to know the limit and date details?
No. My template below asks for these. The lender already knows the details so it doesn’t help your complaint by listing them. Don’t delay making a complain trying to find these out.
Think about these points before complaining
You can complain about open or recently closed accounts
These complaints can be made if your account:
- is still open; OR
- it is closed and settled within the last 6 years; OR
- or if it is with a debt collector and you defaulted within the last 6 years (NB the complaint goes to the original lender, not the debt collector.)
If you have had a DRO, IVA or bankruptcy after these problems, ask in the comments below, as this can be complicated.
Old accounts
Many lenders reject complaints about a card opened more than six years ago and say the ombudsman won’t look at them.
FOS may look at these “old” accounts if they have still been open within the last six years. But you are much more likely to win if there have been limit increases in the last 6 years.
If your account was opened in 2017 say, but the lender increased your limit in 2021, that limit increase is within the last 6 years so it can definitely be looked at. You can always get bank statements going back six years, even from closed bank accounts.
A alternative for old defaulted accounts?
If your account was opened over 6 years ago, you defaulted and still owe a balance, perhaps in a DMP, think about asking the debt collector to produce the Consumer Credit Act agreement for the account.
If the current creditor can’t produce a proper copy of the agreement, the debt cannot be enforced in court and you can simply stop paying anything to it. This applies to all credit cards, store cards and catalogues.
It may be that the balance on the account is larger than any refund you might get. In which case, if the CCA agreement cannot be produced, you would be better off asking for this rather than making an affordability complaint.
Is a refund what you really need?
Any refund sounds good, but is your problem much bigger than this?
Complaining only gets the interest refunded – you still have to repay what you borrowed. If the debt is newish, you may still be left with a large, unaffordable balance.
Don’t spend months arguing with lenders and going to the ombudsman if you will still be in a mess even if you win. So phone National Debtline on 0808 808 4000, tell them you are thinking about affordability complaints but you would like to know what your other debt options are.
Poor reasons to complain
You can’t complain just because the interest rate was high or because you have paid them a fortune over the years.
You won’t win an affordability complaint if something unexpected went wrong later in your life. If you had been managing a credit card fine for years but then you lost your job or separated from your partner, this isn’t the lender’s fault. But you may still need help to get interest stopped on the cards – talk to StepChange or National Debtline about getting new interest stopped when you are in difficulty.
How to complain
The email address to use
The best way to complain is by email. Find the email address here:
Credit card and catalogue email addresses
Start with this template
I’ve invented an example so you can see how a complaint could read.
Change/delete the bits in italics to tell your story. Miss out any dates if you don’t know them, this isn’t a problem
I want to complain about irresponsible lending for my Barclaycard account number 987654/444.
My date of birth is dd/mm/yy. The email address I used for this account was myaddress@whatever.com.
Put this in if you think the lender may have an old address for you
I have moved and my home address is now xxxxxxxxxxxxxxxxxxx. Please do not send any letters to any older addresses on your system.
Put this in if you don’t know some details
I do not know the exact months when the account was opened or any credit limit increases or decreases. In your reply to my complaint, please tell me the dates and amounts of all limit changes, even if these happened over 6 years ago.
Then say IF they should never have given you the account:
You should never have allowed me to open an account with such a large credit limit.
On my income with my regular household expenses and other debts I could not manage to repay that amount in a reasonable time.
[if you had already missed payments] When I applied, you should have checked my credit record and would have seen I had recent missed payments to a credit card and a default only five months before on a loan.
[If this started as a 0% transfer: You should have seen that I would not be able to clear the balance in a manageable length of time, and that after the 0% period ended, I would struggle to pay the higher minimums once interest was being added.]
AND / OR say that they should not have increased your credit limit:
You should never have increased my credit limit. At that time I had only made minimum payments on this credit card for a long while and/or I was using a very high level of my credit limit.
If you had properly checked my credit record before increasing my limit, you would have seen that in the two years since my account with you was opened, I had got additional late payment markers and defaults and/or taken out a lot of other credit. This should have warned you I was struggling with my finances and it was not responsible to lend more. By increasing my credit limit, you made my financial position worse. Instead you should have offered me forbearance by freezing the interest on the card.
If the lender should have known you had problems with your account, mention these
You should also have realised that I was having difficulty because:
of the late payment charges you added to my account
I had missed payments to you in 2023
I had already asked you on the phone if it was possible to stop adding interest for a while.
End with asking for a refund:
I would like you to refund me all the interest I paid and any late payment charges from the point the account was opened
OR
I would like you to refund me all the interest I paid and any late payment charges after you increased my credit limit in 2021.
OR
I would like you to refund all the interest I have paid since the 0% period ended and allow me to clear the balance without adding interest.
I would also like any late payment and default markers to be removed from my credit record. (do not mention this if the credit record for this card doesn’t have problems)
Don’t be put off by a rejection or a poor offer
Lenders often reject good cases
If a lender rejects your complaint or offers a low “goodwill” gesture, don’t be fobbed off – they want you to give up.
Here are some bad or irrelevant comments lenders sometimes make when rejecting a complaint:
- you made the payments to them on time – that doesn’t mean you could manage a higher limit;
- the account was opened over 6 years ago – if it was still open in the last 6 years the Ombudsman may look at it;
- you accepted the limit increase – that doesn’t make a difference! The increase should not have been offered if it was unaffordable.
You know if this card or catalogue has caused you difficulty – it’s easy to send a case to the independent ombudsman. Don’t delay doing this!
How to send a case to FOS
Send FOS a complaint using their online form. You can use bits of what you put in your complaint to the lender. If the lender has rejected your complaint or given a poor offer, say why you think this wrong.
The FOS form at the end asks you to add supporting documents. Don’t bother to send A copy of your credit or finance agreement – the lender will supply that if FOS asks for it.
Send FOS a copy of your credit report, they always want to see it. If you have any old credit reports, send the oldest one you have, otherwise send the current one. You can download a statutory TransUnion report for free.
Also get your bank statements if they will support your complaint and send those to FOS too. Do not wait to be asked by FOS for these.
Ideally you want them 3 months before and three months after the account was opened and before /after any limit increase
FOS is a friendly service but not fast. Just use normal English, not legal terms. Using a claims company or a solicitor doesn’t help or speed this up.

Hi
I submitted an affordability complaint using your template with MBNA for a balance transfer card that I took out in 2017. The credit limit was huge, and they have increased it since then. At the time I took it out I only had one income and a loan which I was paying off so transferred the balance from two other cards to that one. They have looked into it, fairly quickly as well, and have agreed they should not have given me such a large credit limit. They have refunded me £3284.58 which is all the interest and fees I’ve paid them since then. They have also sent me a cheque for £47.27 which is 8% of that for the time I was without funds apparently!
Happy days, thank you for the template and for the advice you provide.
Sara (Debt Camel) says
good result. So it has cleared the balance I assume. If not, that should be interest free.
Anon181 says
I have tried a few smaller credit cards I have that were rejected against my affordability complaint however, I did receive an email out of the blue last week from Capital One to say they were upholding my credit card affordability complaint. The limit was £800 and I owed £740 after paying this months minimum. They refunded the interest and 8% which left a balance of just over £200 in which they have wrote it off as a financial loss and closed my account immediately without any repercussions for myself. I still have another 13/14 months to get out of debt with my remaining cards but I would never have achieved any of this if it hadn’t been for your advice so thank you very much. There is light at the end of the tunnel.
Jamie says
Hi sara,
The judicial review verdict came in June but the FOS seemingly *still* haven’t worked out what they’re going to do. Do you have any idea roughyly how long will it take them to determine a route forward (which I’d have thought would be obvious anyway)?
Thanks
Sara (Debt Camel) says
I don’t know.
(I also don’t know if the very recent Berry v Black Horse judgment is relevant to what FOS decides. That case will going to appeal.)
Gemma says
I contacted Sara as I had accumulated a very large amount of debt and needed some advice! Since then, I have put in a few affordability complaints using this template. I was sat with a fixed balance of £3000 on my capital one card for nearly 2 years, despite balance transfers not helping. I have just received an email confirming a refund!! At the time of the complaint, I had £2,729,22. Capital one have refunded £1,318.53 and reduced my credit limit to £750. With the reduction to my credit limit, they’ve also written off £568.53, so my remaining balance matches my credit limit. This is absolutely insane to me and feels like my debt goals are so much more attainable, waiting to see what the others come back with!! Thank you so much, Sara!
CW says
Hi Sara, I have around £57.5k unsecured debt and have always kept up with payments, but looking back I can see a pattern of repeated consolidation/refinancing.
I’ve anonymised the lenders:
2021 – Loan A £19.5k consolidation
Apr 2022 – Card A £7.6k, almost fully used for balance transfers
May 2022 – Loan B £19.9k consolidation
Nov 2022 – Loan C £25k consolidation
Jul 2023 – Card B £6k, £5.5k used almost immediately
Mar 2024 – Loan D £30k consolidation
Apr 2024 – Loan E £7.6k, just 2 weeks later. This lender also gave me 2 cards with limits increased to £5.85k & £7.85k while I was mainly making minimum payments.
Apr 2025 – Loan F £12k consolidation
Despite all the consolidation, my debt kept growing. By 2024 I had over £40k unsecured debt and by 2025 around £50k.
I don’t want to complain about every lender just because I’m in debt. Does this pattern suggest affordability complaints are worth pursuing, and which lending decisions would you focus on?
Thank you 😊
Sara (Debt Camel) says
are they all from different lenders? This is really easier with lender names…
Despite all the consolidation,
i wouldn’t say “despite”, I would say probably “because…” often a consolidation loan may have looked cheaper than the cards but it was still unaffordable, so you end up using the cards more again
That first consolidation loan may have been what set everything else off. If you don’t want to give names, i suggest complaining about all of the loans. And any cards where you paid a a lot of interest.
CW says
Thanks Sara, that makes sense!
The lenders were:
Lendable – £19,490 consolidation loan (May 2021)
Virgin Money – £7,600 card (Apr 2022, almost fully used for balance transfers)
Admiral – £19,900 consolidation loan (May 2022)
Novuna – £25,000 consolidation loan (Nov 2022)
Lloyds – £6,000 card (Jul 2023, ~£5,560 used almost immediately)
Novuna– £30,000 consolidation loan (Mar 2024)
MBNA – ~£7,600 loan (Apr 2024, 2 weeks after Zopa). I also had 2 MBNA cards with limits increased to £5,850 and £7,850.
Natwest – £12,000 loan (2025)
Thank you 😊
Sara (Debt Camel) says
did the big consolidation loans each clear the previos large loan? or just new cards?
which cards do you think you have paid the most interest on?
can you manage at the moment without using credit cards or BNPL at all? or do the minimum payments leave you too short?>
do you have any 0% ending soon?
CW says
Yes, the big consolidation loans generally cleared the previous large loan plus some cards. The £25k loan cleared the previous £19.9k loan, then the £30k loan cleared the £25k loan plus some cards. The £12k loan in 2025 just consolidated cards.
I think I’ve paid the most interest on my two MBNA cards. I’ve had them since 2019/2021, often carried balances and mainly made minimum payments.
At the moment I can manage all my minimum payments without using credit cards or BNPL for everyday spending.
I have 0% balances ending soon: about £544 and £1,820 in Jan 2027, and £1,694 in May 2027.
Sara (Debt Camel) says
So complaints against all the consolidation loans, including the large first one. And one to MBNA for both cards
