Frequently Asked Questions
What is a typical interest rate for a UK business loan?
For unsecured business loans in the UK, indicative APRs typically range from 10% for prime borrowers to 45% for specialist/adverse credit situations. Secured business loans backed by property typically range from 3% to 15% APR. These are indicative ranges only; your actual rate depends on your credit profile, turnover, trading history, and the lender's current appetite.
How are business loan rates calculated?
Most UK business loan lenders use a combination of credit scoring, bank statement analysis, and sector risk assessment to set rates. Key factors include credit history at both company and director level, trading performance, turnover, profitability, existing debt commitments, and whether any security is offered. Through a broker like Spark Finance, your application is matched to lenders most likely to offer competitive terms for your specific profile.
Are these rates guaranteed?
No. The rates shown are indicative ranges based on applications processed through our lender panel. They represent typical observed rates, not guaranteed outcomes. Your actual rate will depend on your specific circumstances, the lender's current criteria, and underwriting assessment. Spark Finance will confirm indicative rates from suitable lenders before you proceed.
Methodology
Rate ranges are compiled from applications processed through the Spark Finance broker panel during the stated period. They reflect the rates quoted by lenders at initial offer stage, not necessarily the rate at completion. Range boundaries represent the 10th and 90th percentile of observed rates in each category. Outlier cases (very large loans above £5m, or very high-risk specialist situations) are excluded. Data is updated quarterly.
