How to Read a UK Business Loan Offer
A UK business loan offer contains several cost components beyond the headline rate: APR, arrangement fees, early repayment charges, and security costs. Understanding each figure before signing protects your cash flow and allows accurate comparison between competing lenders. This guide explains what every line means and what to negotiate.
Why the Headline Rate Is Not the Full Cost
The headline interest rate on a loan offer tells you only part of the story; the true cost is the Annual Percentage Rate, which folds in mandatory fees and charges to produce a single comparable figure. Lenders are required by the Consumer Credit Act 1974 and FCA rules to disclose APR, but business loans above £25,000 are largely exempt from those disclosure obligations, meaning some lenders present rates without a standardised APR at all.
When no APR is shown, ask the lender for the total amount repayable over the loan term, then calculate the effective annual cost yourself. A loan with a 7% annual interest rate but a 2% arrangement fee on a two-year term has an effective APR closer to 9%. Always base comparisons on total repayable, not the nominal rate.
Arrangement Fees: Types and What Is Negotiable
Arrangement fees are one-off charges levied by the lender for setting up the facility, typically ranging from 0.5% to 3% of the loan amount. These fees are sometimes deducted from the advance at drawdown, so a £200,000 loan with a 2% arrangement fee means only £196,000 lands in your account, yet you repay interest on the full £200,000.
Some lenders split the arrangement fee into a commitment fee (paid on acceptance) and a completion fee (paid at drawdown). If you withdraw after paying a commitment fee, that sum is usually non-refundable. Arrangement fees on larger facilities, typically above £500,000, are more negotiable; on standardised SME products below £100,000 they are generally fixed. Always ask whether the fee can be added to the loan or must be paid upfront.
How Interest Is Calculated: Reducing Balance vs Flat Rate
The method used to calculate interest has a significant impact on true cost, and lenders do not always make the distinction obvious. A reducing balance loan charges interest on the outstanding principal each month, so as you repay capital the interest element falls. A flat rate loan charges interest on the original advance throughout the term, regardless of how much you have repaid.
A flat rate of 5% on a three-year term is roughly equivalent to a reducing balance rate of around 9.1%, depending on repayment frequency. If a lender quotes a flat rate, multiply it by approximately 1.8 to estimate the reducing balance equivalent. Challenger lenders and some fintech platforms favour flat-rate quoting because the lower number looks more attractive; always clarify which basis applies before comparing offers.
Early Repayment Charges Explained
Early repayment charges, sometimes called prepayment penalties or redemption fees, are costs imposed when you repay a loan before the agreed term ends. For fixed-rate loans, the lender is compensating for interest income it will no longer receive; for variable-rate loans the charge is often smaller or absent entirely.
The most common structures are: a flat percentage of the outstanding balance (for example 1% to 3%); a set number of months' interest (often two to six months); or a declining scale where the penalty reduces each year the loan has been running. Some lenders, particularly in the asset finance and invoice finance sectors, charge no early repayment penalty at all. If you anticipate refinancing or selling the business within the loan term, prioritise offers with low or no early repayment charges, even if the headline rate is marginally higher.
Security, Valuation, and Legal Fees
Secured loans require the lender to register a charge over assets, and the costs of doing so are almost always passed to the borrower. Commercial property valuations typically cost between £1,500 and £5,000 depending on property type and location; the lender instructs its own surveyor and you pay the invoice. Legal fees cover the lender's solicitor drafting and registering the charge at Companies House and, where applicable, HM Land Registry.
Expect combined legal and valuation costs of £3,000 to £10,000 on a property-secured deal. These costs are payable whether or not the loan completes in some cases, particularly if the borrower withdraws late in the process. On personal guarantee-only or debenture-secured facilities, legal fees are lower, often £500 to £1,500. Request a full schedule of third-party costs in writing before instructing valuers.
Covenant and Monitoring Conditions
Many SME loan offers, particularly from high-street banks, include financial covenants: ongoing conditions you must meet throughout the loan term, such as maintaining a minimum debt service coverage ratio or keeping net assets above a set threshold. Breaching a covenant can trigger an event of default, allowing the lender to demand immediate repayment even if you have never missed a scheduled payment.
Common covenants include: interest cover ratio (EBIT divided by annual interest) of at least 1.5x; loan-to-value caps if property is security; and restrictions on additional borrowing or asset disposals. Some lenders also require quarterly management accounts or annual audited accounts as a monitoring condition. Review covenant definitions carefully. The definitions of EBIT, net assets, and other metrics can vary between lenders, affecting how easy or difficult the covenants are to meet in practice.
Comparing Offers Side by Side
Comparing loan offers accurately requires reducing every offer to the same three numbers: total amount repayable, effective annual cost (APR or equivalent), and total fees payable before drawdown. This strips away the noise of different rate bases, fee structures, and term lengths.
Build a simple comparison table with columns for each lender and rows for: loan amount requested, amount actually received after fees, monthly repayment, total interest over term, total fees, early repayment charge at year one and year two, and any covenant conditions. Factor in the cost of your time: a lender offering a 0.3% lower rate but requiring quarterly audited accounts and a formal covenant review adds compliance cost that may outweigh the saving. The cheapest offer on paper is not always the lowest total cost in practice.
| Cost Component | Typical Range (UK SME) | Negotiable? | Watch Out For |
|---|---|---|---|
| Arrangement Fee | 0.5% to 3% of loan | Often on larger deals | Deducted at drawdown, interest charged on gross amount |
| Interest Rate Basis | Flat rate or reducing balance | No (product-specific) | Flat rate of 5% equals approx. 9% reducing balance |
| Early Repayment Charge | 1% to 3% or 2-6 months interest | Sometimes | Declining scale vs flat; check at year one and two |
| Valuation Fee | £1,500 to £5,000 | Rarely | Payable even if loan does not complete |
| Legal Fees (lender's) | £500 to £3,000 | Rarely | Separate from your own solicitor costs |
| Commitment Fee | 0.25% to 1% | Sometimes | Usually non-refundable if you withdraw |
| Monitoring / Audit Fee | £500 to £2,000 per year | Sometimes waived | Ongoing cost not shown in initial APR |
Step-by-step
- Obtain the total amount repayable over the full term in writing from every lender you are comparing.
- Clarify whether interest is calculated on a reducing balance or flat rate basis, and convert to a common basis.
- List every fee payable before, at, and after drawdown, including third-party costs such as valuation and legal fees.
- Calculate the effective annual cost by dividing total interest and fees by the loan amount and adjusting for term length.
- Review the early repayment charge schedule and note the cost of exiting at years one, two, and three.
- Read all financial covenants and confirm you can meet them under a mild stress scenario, such as a 15% fall in revenue.
- Compare the three final numbers across all offers: total received, total repayable, and effective annual cost.
Example
A Midlands manufacturer sought £300,000 over four years. Lender A quoted 7.2% reducing balance with a 1.5% arrangement fee and no early repayment charge. Lender B quoted 6.8% flat rate with a 1% fee and three months interest prepayment penalty. Converting Lender B to a reducing balance equivalent produced a rate of approximately 12.2%. Lender A was materially cheaper despite the higher headline rate, saving roughly £28,000 over the term.
Frequently asked questions
Is APR always disclosed on a UK business loan offer?
Not always. Business loans above £25,000 are largely exempt from the FCA's mandatory APR disclosure rules that apply to consumer credit. Lenders may quote an annual interest rate or a factor rate instead. Always ask for the total amount repayable over the full term and calculate the effective annual cost from that figure.
Can I negotiate an arrangement fee with a UK business lender?
On standardised SME products below around £100,000, arrangement fees are usually fixed and non-negotiable. On larger or more complex facilities, particularly above £500,000, there is more flexibility. A business with strong financials, good security, or existing banking relationships is in the best position to negotiate. A commercial finance broker can also sometimes secure reduced fees through volume relationships with lenders.
What happens if I breach a financial covenant?
Breaching a covenant is technically an event of default, giving the lender the right to demand immediate repayment of the outstanding balance. In practice, most lenders seek a waiver or amendment before exercising that right, particularly for a first breach. You should notify your lender as soon as you anticipate a covenant breach rather than waiting for it to occur; proactive communication significantly improves the outcome.
How does the Bank of England base rate affect my loan offer?
Variable-rate business loans are typically priced as base rate plus a margin, for example base rate plus 3.5%. With the Bank of England base rate at 3.75% as of June 2026, that pricing would produce a current rate of 7.25%. If the base rate falls, your monthly payments fall accordingly; if it rises, they increase. Fixed-rate loans are unaffected by base rate movements after drawdown.
What is a debenture and does it add cost to my loan?
A debenture is a fixed and floating charge over all company assets, registered at Companies House. Most unsecured business loans from banks and many fintech lenders still require a debenture as security. Registration costs are modest, usually £100 to £500, but the debenture restricts your ability to grant security to other lenders without consent, which can complicate future borrowing.
