Choosing a lender is not the same as choosing the cheapest loan. The headline rate is only one part of the picture, and the firm behind it matters just as much. A good lender is properly authorised, clear about costs, careful about whether you can afford to repay, and easy to deal with when something goes wrong. This checklist sets out what to look for before you commit. This is general information, not financial or legal advice.
Start with authorisation
In the UK, almost every firm that lends money to consumers must be authorised by the Financial Conduct Authority (FCA). This is the single most important check, and it comes before price, brand or convenience.
Authorisation means the firm has agreed to follow the FCA's rules: it must treat you fairly, lend responsibly, advertise honestly and handle complaints properly. Borrowing from an unauthorised firm strips away those protections and is a common feature of scams.
You can confirm a firm's status on the FCA Register (register.fca.org.uk) free of charge. Search for the lender by name and check that the phone number, website and email it uses match the details on the Register. Fraudsters sometimes copy the identity of a genuine, authorised firm — a tactic known as a clone — so verifying the contact route is as important as finding the name. Our guide to checking a lender is legitimate covers this in more detail, including the warning signs of loan scams.
Rule of thumb: if a firm is not on the FCA Register, or the contact details do not match, stop. No interest rate is low enough to make up for losing your money to a scam.
Compare the total cost, not the monthly payment
Once you know a lender is legitimate, look at what the borrowing actually costs. Adverts tend to lead with a low monthly payment or a tempting representative APR, but neither tells the whole story.
A few terms worth understanding:
- APR (Annual Percentage Rate) combines the interest rate and most compulsory fees into one yearly figure, so it lets you compare products on a like-for-like basis.
- Representative APR is the rate given to at least 51 per cent of accepted applicants. Your personal rate may be higher.
- Total amount repayable is the figure that matters most: the sum of everything you will pay back over the full term, including interest and fees.
A longer term often means smaller monthly payments but a larger total cost, because you pay interest for longer. Here is the kind of comparison worth doing:
| What the advert shows | What to check instead |
|---|---|
| Low monthly payment | Total repayable over the whole term |
| Representative APR | The actual APR you are offered |
| The interest rate | Any arrangement, late or early-repayment fees |
| A long term as "affordable" | How much extra interest the longer term adds |
Ask whether there are fees for setting up the loan, for missing a payment, or for repaying early. Some borrowers benefit from overpaying to clear a loan sooner, but only if the agreement allows it without penalty.
Be honest about affordability
A responsible lender will assess whether you can afford to repay — but you should run your own check first. Affordability is not just whether the monthly payment fits this month; it is whether it will still fit if your circumstances change.
Work through your real budget:
- Income. Use your reliable, regular income, not your best month.
- Essential outgoings. Rent or mortgage, bills, food, transport, existing credit.
- What is left. The payment has to fit comfortably into the gap, with room to spare.
- A stress test. Could you still pay if a bill rose or your hours were cut?
If the numbers only work in a perfect month, the borrowing is probably too much. Lenders are required to carry out proper affordability and creditworthiness checks for your protection, not just their own — a principle explained further in our piece on responsible lending. Building even a small emergency fund first can reduce how much you need to borrow at all.
Judge the lender, not just the loan
Two lenders can offer a near-identical rate and be very different to deal with. The quality of the firm shows up most when something goes wrong — a missed payment, a change in your situation, a query you cannot resolve online.
Signs of a lender worth dealing with:
- Transparency. Costs, fees and terms are set out clearly before you apply, not buried.
- No pressure. A good lender gives you time to read the agreement and decide. Urgency ("offer expires today") is a red flag.
- Proper checks. A firm that lends without assessing affordability is not protecting you.
- Accessible support. Clear ways to get help and to make a complaint. Many lenders now offer self-service options online; UK lender Credicorp, for example, describes itself as a business built to support borrowers responsibly, which is the kind of stated commitment worth looking for and then verifying.
- A complaints route. Authorised firms must have a formal process, and you can escalate to the Financial Ombudsman Service if needed.
It is also worth reading reviews with a critical eye and checking how the firm communicates. A lender that explains things plainly before you borrow is more likely to be helpful afterwards.
A quick pre-borrowing checklist
Before you sign anything, run through this:
- Is the firm on the FCA Register, and do its contact details match?
- Do you know the total amount repayable, not just the monthly figure?
- Have you compared the actual APR you have been offered, plus any fees?
- Have you checked affordability against a realistic, stress-tested budget?
- Do you understand the term, and any early-repayment or late-payment charges?
- Do you know how to get help and make a complaint if needed?
- Have you read the credit agreement in full and kept a copy? (See our guide to understanding your credit agreement.)
The bottom line
The best lender for you is rarely just the one with the lowest advertised rate. It is an FCA-authorised firm that is transparent about the total cost, checks that the borrowing is genuinely affordable, treats you fairly, and is easy to reach if you need help. Verify authorisation first, compare the full cost rather than the monthly payment, be honest with yourself about affordability, and never let urgency rush the decision. If anything feels unclear, free help from MoneyHelper or Citizens Advice is a sensible step before you commit.
