How they differ
A flat rate applies the interest percentage to the full amount borrowed for every year of the term, even though you are steadily repaying. A reducing-balance rate (like a normal APR) charges interest only on what you still owe, which falls each month. Because a flat rate ignores your repayments, a 6% flat rate is roughly equivalent to a 11–12% reducing-balance rate — nearly double.
What this means for your company
Flat rates make a loan look cheaper than it is. Always convert to a comparable figure before choosing — the true-cost calculator does it for you. Compare offers on total repayable, never on the headline rate. If a lender only quotes a flat or factor rate, ask for the total pounds you would repay.

Frequently asked questions
Why does a flat rate cost more?
Because it charges interest on the whole original sum for the full term, ignoring the fact you are paying it down. You end up paying interest on money you have already repaid, which roughly doubles the effective cost.
How do I compare a flat rate to an APR?
Convert both to total repayable in pounds, or use a true-cost calculator to express the flat rate as an equivalent APR. Never compare a flat rate directly against a reducing-balance rate — they are not the same scale.
