My bank wants to lower my credit limit on my credit card. Will this impact me negatively?
No, it will have no negative impact on getting a mortgage. You are building up a history with regular payments and are not carrying a balance on the card each month. Your ability to get a mortgage will ultimately be based on other things. Money Saving Expert has a good guide on what will affect your credit score. A further discussion on the topic that backs up that what a mortgage company is interested in is affordability and a stable history. They really don't care about utilisation ratios.  (Though might be spooked by almost maxed out cards - sign of poor spending control, or large unused limits - too easy to go into bad debt.) Will having a lower credit limit, which I will still never reach, negatively impact my ability to get a mortgage in future? This would increase your utilization, the percentage of your total available credit that you use at any one time.  Because it decreases the divisor, your total available credit, while not changing the dividend, the amount of your credit that you use.  In the United States, you generally want utilization to be between 8% and 30%.  So if this increases your utilization, it could hurt your credit score (or if your utilization is low enough, possibly help it).   I do not know if the rule is the same in the United Kingdom or not, but this site claims that it is at least similar.   22% is an OK utilization, assuming you have no other debt.  But a utilization of 17% is closer to 8% and may be better.  It may be worth calling them to keep your credit limit where it is if they don't ask too much from you.
I was hoping to comment on the original question, but it looks to me like the asker lives in the EU, where credit cards are a lot less common and a lot of the arguments (car rental, building up of credit etc) brought forward by people living in the US just don't apply.  In fact especially airlines (and other merchants) will charge you extra when using a credit card instead of a debit card and this can add up fairly quickly. I hold a credit card purely for travelling outside the EU and occasionally I will travel for work and make my own arrangements, then it can come in handy as I am able to reclaim my expenses before I have to pay my credit card bill (in this case I will also claim the extra credit card fees from my employer). This however is for my personal convenience and not strictly necessary. (I could fill out a bunch of paperwork and claim the costs from my employer as an advance.) In the EU I find that if my VISA debit card will not work in a shop, neither will my credit card, so on that note it's pretty pointless. So to answer the asker question: If you live (and travel) in the EU  you don't need a credit card, ever. If you travel to the US, it would be advantageous to get one. Occasionally banks will offer you a credit card for free and there's no harm in taking it (apart from the fact that you have one more card to keep track off), but if you do, set up a direct debit to pay it off automatically.  And as other people have said: Don't spend money you don't have. If you are not absolutely sure you can't do this, don't get a credit card. Because even if you won the lottery, without at least some credit history you will have trouble renting cars and hotel rooms. I learned about the importance, and limitations of credit history when, in the 90's, I switched from using credit cards to doing everything with a debit card and checks purely for convenience. Eventually, my unused credit cards were not renewed. At that point in my life I had saved a lot and had high liquidity. I even bought new autos every 5 years with cash. Then, last decade, I found it increasingly hard to rent cars and sometimes even a hotel rooms with a debit card even though I would say they could precharge whatever they thought necessary to cover any expenses I might run. I started investigating why and found out that hotels and car rentals saw having a credit card as a proxy for low risk that you would damage the car or hotel room and not pay. So then I researched credit cards, credit reports, and how they worked. They have nothing about any savings, investments, or bank accounts you have. I had no idea this was the case. And, since I hadn't had cards or bought anything on credit in over 10 years there were no records in my credit files. Old, closed accounts had fallen off after 10 years. So, I opened a couple of secured credit cards with the highest security deposit allowed. They unsecured after a year or so. Then, I added several rewards cards. I use them instead of a debit card and always pay in full and they provide some cash back so I save money compared to just using a debit card. After 4 years my credit score has gone to 800+ even though I have never carried any debt and use the cards as if they were debit cards. I was very foolish to have stopped using credit cards 20 years ago but just had no idea of the importance of an established credit history. And note that establishing a great credit history does not require that you borrow money or take out loans for anything. just get credit cards and pay them in full each month. I faced something similar for travel or work reasons, and as for me I preferred wire transfer over credit card withdrawals because my bank has huge fees. My thoughts so far are: the fee can vary a lot for credit card. As for me, I can expect 5% fees on foreign withdrawals. But I considered changing bank and I think a Gold (or premium) card might be a good idea as well. The idea is you pay a big subscription (100 euros or so) but have no fee. The total of withdrawal fees could easily (if you stay long abroad) reach this amount. There are also banks like HSBC that offer low fees on withdrawals abroad, you can ask them. The problem is that you cannot really withdraw huge amounts to lower the fee (since you carry this cash in the street). for wire transfers the total fee is usually $50 or more (I had a fee from distant bank, a fee for change and a fee in my home bank). But the amount is unlimited (or high enough to be of little matter) and I needed to do this once per year or so. So I guess it could be interesting if you have enough savings to only transfer money every couple of months or so. I think Western Union is also involved this profitable business. I never used it because the fees are pretty high, but maybe it is useful for not too big amounts frequently transfered. Actually, have you considered a loan? It's a very random idea but maybe you can use a loan as a swap and then transfer money when you have enough to reimburse it all. But the question is very interesting, I think the business is pretty huge due to globalization. It is expensive because some people can make a lot of money out of it. My son who is now 21 has never needed me to cosign on a loan for him and I did not need to establish any sort of credit rating for him to establish his own credit.  One thing I would suggest is ditch the bank and use a credit union. I have used one for many years and opened an account there for my son as soon as he got his first job. He was able to get a debit card to start which doesn't build credit score but establishes his account work the credit union. He was able to get his first credit card through the same credit union without falling work the bureaucratic BS that comes with dealing with a large bank. His interest rate may be a bit higher due to his lack of credit score initially but because we taught him about finance it isn't really relevant because he doesn't carry a balance. He has also been able to get a student loan without needing a cosigner so he can attend college.  The idea that one needs to have a credit score established before being an adult is a fallacy. Like my son, I started my credit on my own and have never needed a cosigner whether it was my first credit card at 17 (the credit union probably shouldn't have done that since i wasn't old enough to be legally bound), my first car at 18 or my first home at 22. For both my son and I, knowing how to use credit responsibly was far more valuable than having a credit score early. Before your children are 18 opening credit accounts with them as the primary account holder can be problematic because they aren't old enough to be legally liable for the debt. Using them as a cosigner is even more problematic for the same reason. Each financial institution will have their own rules and I certainly don't know them all.  For what you are proposing I would suggest a small line of credit with a credit union. Being small and locally controlled you will probably find that you have the best luck there. Cash back from credit cards is handled separately than the rest of the purchase, i.e. interest begins accumulating on that day, and likely at a higher rate, and usually comes out of a lower limit than the credit allotted to that card. Given all these differences, and the obvious revenue-generation situation for the lender, it makes sense for them to give the store an incentive, rather than penalize them further, for the use of such a feature.  Note: I am not privy to the inner-workings or agreements between large stores and credit lenders, so I cannot guarantee any of this. "I think they gave you the answer: You haven't previously shown that you can run that particular card up to (near) its existing maximum and then pay it off, so they don't have a strong indication that you can handle that large an unsecured loan. Generally, requests to have the limits raised when there isn't evidence that the customer is finding the current limit inconvenient are going to be considered suspicious. Remember, a great credit rating does not require that they consider you a good risk -- it's just one of the things they consider. Why do you need the limit raised? Have you tried contacting the bank's credit department directly and discussing what they will or won't let you do? Re paying off the card every month: Remember, they do get a processing fee from the vendor. They'd prefer that we paid interest (I'm told the term of art for those of us who don't is ""deadbeats""), but they certainly don't lose money when we don't. And they'd generally rather have us be loyal customers who MIGHT someday pay interest, and who are bringing in fees, than have us go elsewhere." It is an issue of both utilization and average age of accounts. If your cards with $0 balances on them are: A) newer cards than the ones you are carrying balances on and you don't want them B) much lower limit cards than the ones you are carrying balances on then you can raise your score by closing them, as the utilization change won't be a large factor and you can raise the average age of your open accounts. No.  It means each month the total amount you owe goes up by a factor of (1+0.298/12).  So if you owed $23K at the beginning of the month, at the end you owe a total of 23K*1.0248=$23,571.  Then subtract the $804 you are paying.  If you want to think of it in terms of interest and principal, you are paying $571 a month in interest and 233 toward principle, I guess. Paying off debt with a lower interest rate using debt with a higher interest rate is throwing a lot of money away and impoverishing yourself needlessly.  Psychology can't get around that.  If you want a psychological aid, decide how much you are going to pay toward these debts and have it automatically deducted from your paycheck so you never see it. Make the minimum payment on every debt you have except the one with the highest interest rate.  Pay the very most you can toward that.  Then when it is paid off, move to the next highest.  Do all your spending out of the lowest rate card, or avoid using these credit cards until your financial discipline and resources allow you to pay all credit cards off completely at the end of each month.
