Key takeaways
£300 was the third most requested amount in applications made through us in the first half of 2026, and a third of all applications were for £300 or less.
Over 3 months, £300 costs about £33.87 in interest. Over 12 months, it costs about £118.68 (illustration, representative 79.5% APR).
For a repair or a replacement appliance, get a written quote and borrow that figure rather than a round number.
If the loan counts as high-cost short-term credit, you can never be asked to repay more than £600 in total.

A £300 loan is often for something specific: a garage bill, a broken washing machine, or a bill that has landed at the wrong time. That makes it easier to plan than a general shortfall, because you can find out the exact cost first. This page covers how to do that, what £300 costs over different terms and the options worth comparing. Dot Dot Loans is a credit broker, not a lender, so any offer and its rate come from the lender.

Start with the exact cost

In our Borrowing Barometer, applications for £100 to £300 were most often for utility bills (42.2%) and emergency cash (30.1%), with home improvement (10.9%) and vehicle costs (10.6%) next. Whatever the reason, borrowing a round £300 when the job costs £240 means paying interest on £60 you did not need. Before you apply:

  • For a car repair, ask the garage for a written, itemised quote, and ask which work is needed now and which can wait. If the car has failed its MOT, the failure certificate lists what must be fixed. Some garages will let you spread the cost.
  • For a broken appliance, check whether it is still under warranty or covered by your home insurance, and compare the price of a reconditioned model. Charities and local welfare schemes can sometimes provide essential appliances; the Turn2us grant search is a good place to start.
  • For a bill, ask the company about a payment plan before you borrow.
  • For anything else, compare an arranged overdraft or a credit union loan, either of which may cost less for a short gap.

Figures assume a representative 79.5% APR and are for illustration only. Your actual rate depends on the lender and your circumstances.

At the representative rate, each extra three months adds roughly £27 to £30 in interest. If you can afford the 3-month payment of £111.29 without leaving yourself short, it is the cheapest option shown. If it would leave you short, a longer term costs more but is safer than missing payments.

If your loan has an APR of 100% or more and is due to be repaid within 12 months, it is high-cost short-term credit. On £300, the FCA cap limits interest and fees to £2.40 a day, and you can never repay more than £600 in total, whatever happens.

Representative Example: Borrow £1,000 over 18 months. 18 monthly repayments of £89.22. Total amount repayable: £1,605.96. Interest: £605.96. Annual interest rate: 59.97% (fixed). Subject to application approval by the lender. Not all lenders offer loans up to £5,000. Representative APR 79.5% (Variable). Any representative monthly repayment shown is for illustration only, based on our representative APR. Your actual repayments will be confirmed by the matching lender if your application is approved.

Who a £300 loan suits

A good fit if
You know the exact cost and it cannot wait
Your income over the next few months is steady and predictable
The repayment still leaves room for other surprises
Not a good fit if
You would use it to repay another loan
You are already behind on rent, council tax or energy bills
Your income is about to drop, for example because a contract is ending

If you are already behind on priority bills such as rent, council tax or energy, free debt advice is the better first step. An adviser can often agree lower payments with the people you owe, which a loan cannot do.

If you are declined for £300

A decline on a small amount is usually about affordability or recent credit history rather than the size of the loan. Applying to lender after lender adds hard searches to your file and can make the next decline more likely. Instead, check your credit reports for free with Experian, Equifax and TransUnion, correct any mistakes, make sure you are on the electoral register at your current address, and look at the options above.

Frequently asked questions

How much does £300 cost over 6 months?

At our representative 79.5% APR, about £60.14 a month, or £360.84 in total (illustration only). The lender will confirm your actual rate before you agree.

Can I use a £300 loan for car repairs?

Yes. Car repairs and MOT work are a common reason for borrowing this amount. Get an itemised quote first so you borrow only what the repair costs, and check whether the garage offers its own payment terms.

What is the most I could have to repay on £300?

That depends on your agreement, so check the total amount repayable in the lender's pre-contract information. If the loan is high-cost short-term credit, the FCA cap means you will never repay more than £600, including any default fees and interest.

Can I change my mind after taking out a £300 loan?

Yes. You can withdraw from most credit agreements within 14 days without giving a reason. You must then repay the £300 and the interest for the days you had it, within 30 days of telling the lender.

Why would I be declined for £300?

The most common reasons are that the repayments do not look affordable on the figures you gave, or that there are recent missed payments on your credit file. Our guide to declined applications explains what to check.
