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.
Paying weekly to be able to have maneuver room under your credit limit is a way to handle low credit limits. Doing it to boost your credit score when you have no immediate need for a loan is wasting energy.  A few months in advance of buying a car or house, you can start to worry about your utilization rate. When you apply for the loan they will pull your credit file, and that will lock in your utilization rates. Then make sure that you pay the balance quickly, and if you need to make a big purchase pay the bill before the account closes for the month. Keep in mind that if you pay the balance every month the highest utilization rate will occur the day the payment is due. This is because it not only has all the purchases from the previous bill, but all the purchases you have made since that bill closed. For example if you have a credit limit of 10K and you spend 2K a month on the credit card, on the day the payment is due it is not unusual to see the total owed to be above 3K. If they pulled your file on that day, your utilization rate would appear to be above 30%. 5% cashback? Wow. No, this would not generally affect your credit rating. You aren't altering anything that is generally tracked by the credit rating agencies. You put a purchase on your credit card which temporarily increases your utilisation, but then immediately pay it off, leaving your utilisation practically unchanged. If you want to close the card, close it.  The impact on your credit score will be minimal, if any, and the impact on your life will likely be even less.  First, as you noted, the history from your card does not disappear when you close the card; it will stay on your credit report for as long as 10 years. By that time, you'll have many years of on-time payments from your other cards, and the loss of this one card won't be significant.  Because the card has a low credit limit, it won't have much effect on your credit utilization numbers, either.  Finally, your credit score might just be high enough that a small drop will have no impact on your financial life whatsoever.  In my opinion, hanging onto a credit card you don't want just to try to attain some type of high score is pointless. Close the card. The answer to your question is no. Your credit rating is the way creditors let each other know whether you are in a good position and have a strong tendency to repay your debts, not whether you are an easy target for making money on interest and penalties associated with failing to repay debts in full.  The fact that you make your payments on time will definitely not lower your credit rating. While the banks are not making as much money on you as they would if you carried a balance, they are also not spending a lot of money on you, nor losing a lot of money on people like you failing to repay debts.  The transactions charged to the retailers cover the costs of operating your card and then a little bit.  That is enough to make you worth keeping as a customer.  They are happy with your arrangement. The formula for credit rating computation is proprietary, but we know what the factors are overall.  Making payments on time consistently is a positive, not a negative factor.  However, they do look at the number of cards and overall mix of cards and other types of debt.  For example, if you have a very large amount of credit capacity in your cards and no mortgage, that could possibly be a negative.  If you have opened some of those accounts recently, it could be a negative.  If you have a larger number credit cards than they think is good, that could be a negative. There are other things as well that could be bringing your score down.  Probably worth it to take a look. If you want to get an idea of what factors are adding positively and negatively to your credit score, I'd encourage you to visit CreditKarma.com, Quizzle.com, or another source intended to help you understand and improve your credit rating. "Sometimes you need to do more than ask to have your rating reduced.  You need to make it in their best interest (no pun intended) to do it. Find the lowest rate card and then tell the others you want to transfer your balance to that card and close the account (don't do it, it is an empty threat). I guarantee they will transfer you to a retention agent who will give you a better deal.  From their perspective your current offer is getting 19% interest instead of 22%, why would they do that without some motivation? With the approach described above their options are get 19% interest instead of 0% interest. It is all about negotiation and the ""Retention agents"" have the most leverage to do so." "Generally it is not recommended that you do anything potentially short-term deleterious to your credit during the process of seeking a mortgage loan - such as opening a new account, closing old accounts, running up balances, or otherwise applying for any kind of loan (people often get carried away and apply for loans to cover furniture and appliances for the new home they haven't bought yet). You are usually OK to do things that have at least a short-term positive effect, like paying down debt. But refinancing - which would require applying for a non-home loan - is exactly the sort of hard-pull that can drop your credit rating. It is not generally advised. The exception to this is would be if you have an especially unusual situation with an existing loan (like your car), that is causing a deal-breaking situation with your home loan. This would for example be having a car payment so high that it violates maximum Debt-to-Income ratios (DTI). If your monthly debt payments are more than 43% of your monthly income, for instance, you will generally be unable to obtain a ""qualified mortgage"", and over 28-36% will disqualify you from some lenders and low-cost mortgage options. The reason this is unusual is that you would have to have a bizarrely terrible existing loan, which could somehow be refinanced without increasing your debt while simultaneously providing a monthly savings so dramatic that it would shift your DTI from ""unacceptable"" to ""acceptable"". It's possible, but most simple consumer loan refis just don't give that kind of savings. In most cases you should just ""sit tight"" and avoid any new loans or refinances while you seek a home purchase. If you want to be sure, you'll need to figure out your DTI ratio (which I recommend anyway) and see where you would be before and after a car refinance. If this would produce a big swing, maybe talk with some mortgage loan professionals who are familiar with lending criteria and ask for their opinion as to whether the change would be worth it. 9 times out of 10, you should wait until after your loan is closed and the home is yours before you try to refinance your car. However I would only warn you that if you think your house + car payment is too much for you to comfortably afford, I'd strongly recommend you seriously reconsider your budget, current car ownership, and house purchasing plans. You might find that after the house purchase the car refi isn't available either, or fine print means it wouldn't provide the savings you thought it would. Don't buy now hoping an uncertain cost-saving measure will work out later." "The question asked in your last paragraph (what's the downside) is answered simply; if you take out a loan and close the cards, that's a ding on your score because your leverage ratio on this portion of your credit jumps to 100% or more, and because you'll be reducing the average age of your lines of credit (one line of credit a few days old versus five lines of credit several years old each). If you take out the loan and don't close the accounts, it's one more line of credit, increasing your total credit, lowering your leverage, but making institutions more reluctant to give you any more credit until they see what you'll do with what you have. In either case, assuming you can get the loan at less than the average rate of the cards (that's actually not a guarantee; a lot of lenders will want APRs in the 20s or 30s even for a title loan or other collateralized loan), then your cost of capital will also go down. That gives you more of a gap of discretionary income that you can better use to ""snowball"" all this debt as you are planning. Another thing to keep in mind is that the minimum payment changes as the balance does. The minimum payment covers monthly interest at least, and therefore varies based on your interest rate (usually variable) and your balance (which will hopefully be decreasing). A constant payment over the current minimum, much like a more traditional amortization, would be preferable." My card keeps a separate 'cash advance' limit, that's lower than the regular rate. I believe balance transfers also trigger that limit and (much higher) interest rate. The only drawback is if you spend more than you can with the new limit and end up having to pay interest if you can't pay the balance in full. Other than that, there are no drawbacks to getting a credit increase.  On the flip side, it's actually good for you. It shows that the banks trust you with more credit, and it also decreases your credit utilization ratio (assuming you spend the same). Assumptions 1 & 2 are correct. Plus you will improve on credit score. The only disadvantage is if you get lax about it and overspend beyond your limit ... Plus a small risk of fraud of card transactions ... "Here's my crude reasoning: Let's say you have just one recently acquired credit card with a $5000 limit. The company that issued the credit card set the $5000 limit based on however they assessed your risk. Now if you're using a significant portion of of the $5000 limit, it means (at least for them) that you are stretching your wallet. Even if you've been paying monthly consistently and since you are heavily using your limit, it also means that if you lose your primary source of money for even one month, (income etc.), then your risk to the lender increases sharply. Had you been making more money (compared to this $5000 limit) then either you'd have used less % of your available credit or you would've gotten your limits raised by asking your bank to re-evaluate your risk and increase the limit. Also your statement ""Why is a US credit score based on credit utilization?"" is slightly incorrect. As per FICO, Credit utilization has 35% weight while your payment history has a weight of 35% http://www.creditcards.com/credit-card-news/help/5-parts-components-fico-credit-score-6000.php To sum it up, we can debate if the weight for credit utilization should be higher or lower but unfortunately as others have pointed out, these scores are meant to help lenders not consumers. So whether we like it or not, the secret algorithms to calculate the scores and the actual weights (variables and rules) they use are completely out of our hands." "Your use of the term ""loan"" is confusing, what you're proposing is to open a new card and take advantage of the 0% APR by carrying a balance.  The effects to your credit history / score will be the following:" Overpaying a credit card to create a large positive balance may cause a bank to red flag your account.  This is a technique used in fraud for check kiting (write or deposit a fraudulent check to overpay your credit card, then demand a refund on the balance overpaid before the check bounces.) Every bank is different: Talk to your bank first before you try this.  For a small balance ($5-20) overpayment isn't a big deal, it happens regularly... just spend down the balance.  Past that, you might be harming your credit record or risk closing the account if the bank disagrees with how you are using an overpaid balance for a larger purchase, or you risk unwanted law enforcement attention aimed at your finances. If you are trying to do this to build your creditworthiness, a secured card is better for this purpose.  Disagree with your credit limit? Deposit more in the holding account. "I'm the contrarian on this forum. Since you asked a ""should I ..."" question, I'm free to answer ""No, you shouldn't increase your limit. Instead, you should close it out"". A credit card is a money pump - it pumps money from your account to the bank's profit margins. When I look at my furniture and the bank's furniture, I know exactly who needs my money more (hint: it's not the bank). Credit cards change people's spending patterns. In my first day of training as a Sears salesman, the use of the card was drummed into our heads. People purchase on average 25% more when they use a card than when they pay cash. That's good if you're a retailer or the lender (at that time Sears was both), but no good if you're a consumer. Build up a $1,000 emergency fund (for emergencies only, not ""I need a quick latte because I stayed up too late last night""), then savings for 6 to 12 months living expenses. Close and cut up the credit card. Save up and pay cash for everything except possibly your house mortgage. If you have that much cash in the bank, the bankers will be as willing to talk to you as if you had an 800+ score. I have lived both with and without debt. Life without debt is well worth the short term sacrifice early on." You could use a stock-only ISA and invest in Exchange Traded Funds (ETFs). ETFs are managed mutual funds that trade on open exchanges in the same manner as stocks. This changes the specific fund options you have open to you, but there are so many ETFs at this point that any sector you want to invest in is almost certainly represented.
