Two types of loan fee

Every loan has a cost. But the fees attached to that cost fall into two completely distinct categories — and confusing them is one of the most common mistakes borrowers make.

Mandatory fees
Charges you must pay as a condition of borrowing. These must be included in the APR and disclosed in your credit agreement before you sign. You cannot opt out of them.
Optional fees
Add-ons you can choose to buy — such as payment protection insurance or account management tools. A lender cannot make these a condition of approval.

UK consumer credit law — principally the Consumer Credit Act 1974 and FCA CONC sourcebook — requires lenders to be clear about both types and prohibits bundling optional products into the headline rate.

Mandatory fees: what lenders can charge

These charges are a condition of the credit. Because they are mandatory, the law requires them to be factored into the APR figure shown in any advertisement or pre-contract information. The most common examples are:

Arrangement / establishment fee
A one-off charge applied when the loan account is opened. Typically a flat amount (e.g. £5–£50 depending on lender and product) or occasionally a percentage of the loan amount.
Administration fee
Covers processing costs. Must be stated in the credit agreement. Rare on simple personal loan products but more common on secured or bridging finance.
Compulsory insurance
Some niche products require certain insurance as a loan condition (rare in mainstream unsecured lending). If it is compulsory, its cost must be in the APR.

Key rule: If a fee is mandatory, it must appear in the credit agreement you sign and must be reflected in the APR. If a lender charges a mandatory fee that is not in the agreement, you can challenge it under the CCA 1974.

Optional add-ons: what you can refuse

These products are sold alongside loans but are not conditions of borrowing. You can say no without affecting your approval or your interest rate. Common examples in UK consumer lending include:

Payment Protection Insurance (PPI)
Covers repayments if you cannot work due to illness, injury, or redundancy. Historically mis-sold as compulsory — today it must always be presented as a separate, optional purchase.
Guaranteed Asset Protection (GAP)
Mainly relevant to vehicle finance — covers the difference between your insurer's payout and the outstanding loan if the vehicle is written off.
Loan account management tools
Some lenders offer premium features (e.g. payment date flexibility, hardship portals) as paid add-ons. These are optional upgrades, not conditions of the loan.
Credit score monitoring
Occasionally offered alongside loan applications. You can access free versions via agencies such as Experian, Equifax, or TransUnion directly.

Worked example: what a flat fee really costs you

A flat arrangement fee can look small in isolation. Seeing it as a percentage of the loan amount — and reflected in the total repayable — makes its real cost clear. The figures below are indicative and subject to status and affordability.

Cash Train Flex — £500, 6 months
49.9% APR (representative)
£5 establishment fee (included in total)
Monthly payment: £95.21
Total repayable: £571.26
Interest + fee = £71.26 on £500 borrowed
Same loan — hidden £30 admin charge
Same stated interest rate
£30 admin fee not in the APR
Monthly payment: looks the same
Actual total: £596.26+
The extra £25 never appeared in the APR

The second scenario illustrates why a mandatory fee that is not included in the APR is a red flag. Under UK consumer credit rules, that charge should either be in the APR or disclosed separately as a distinct, optional purchase. If it appears nowhere in your credit agreement, the lender has no contractual right to collect it.

Representative example: borrow £500 over 6 months at 49.9% APR (fixed). Monthly repayment £95.21. Total repayable £571.26. Rates from 39.9% APR (Plus) to 149.9% APR (Quick). Available on loans £100–£5,000. Subject to status and affordability.

Default charges: a separate category

Default charges are neither mandatory nor optional in the normal sense — they are contingent. They only apply if something goes wrong with your repayment. UK rules require them to be:

Stated clearly in the credit agreement before you sign
A genuine pre-estimate of the lender's reasonable administrative cost — not a profit source
No higher than the lender's actual cost for handling the default event

Common default charges in UK personal lending include a missed payment fee (typically £15–£25) and a returned direct debit fee. If a lender charges more than the stated amount in your agreement, or applies a charge not listed in the agreement, you can raise a formal dispute.

If you are struggling to keep up with repayments, contact your lender before a payment is missed — most will have a hardship process that can pause or restructure charges before default fees are triggered.

Quick reference: fee checklist before you sign

Is the fee in the APR? If yes — it's mandatory and legally disclosed. If no — ask why.
Is the fee in the credit agreement? If mandatory, it must appear here. No mention = no legal right to charge it.
Is the add-on truly optional? Confirm in writing. Declining should not change your rate or approval outcome.
What is the default charge? Must be stated upfront. Should reflect actual admin cost, not profit.
What is the total repayable? This single figure includes everything. Compare it — not just the APR.
Is there an early settlement right? Under the CCA 1974, you can repay early and receive a rebate on future interest.
Common questions

FAQ

An arrangement fee — sometimes called an establishment fee or admin fee — is a one-off charge a lender applies when setting up your loan. It covers the administrative cost of processing your application and opening the account. UK lenders must include any mandatory arrangement fee in the APR calculation so you can compare costs on a like-for-like basis.
No. Under the Consumer Credit Act 1974, all charges that are a condition of the credit must be disclosed in the credit agreement before you sign. A lender cannot add new mandatory fees after you have signed. If unexpected fees appear on your statement that were not in the agreement, you can raise a complaint with the lender and, if unresolved, with the Financial Ombudsman Service.
No. Payment protection insurance is an optional add-on. A lender may not make approval of your loan conditional on buying PPI or any other optional insurance product. Always read the pre-contract information to confirm whether insurance is optional before signing. If you were sold PPI as a condition of the loan without disclosure, you may have grounds for a complaint.
Cash Train charges a one-off £5 establishment fee on applicable products, which is included in the total repayable shown to you before you sign. There are no hidden admin, processing, or broker charges on top of that. Optional add-ons, if offered, are clearly disclosed as optional and will never affect your approval decision.

No hidden charges — ever.
