Choosing between unsecured and secured business loans affects cost, speed, and risk. This guide explains how each works, who they suit, and what to watch out for, with references to trusted UK sources.

What is an unsecured business loan?

An unsecured business loan lets you borrow without pledging specific assets as collateral. Lenders assess creditworthiness, trading history, and cash flow. Because there is no asset backing, pricing can be higher and limits tighter. A plain‑English overview of secured versus unsecured lending is set out by Investopedia.

In the UK market, unsecured loans are often positioned for firms that lack property or equipment or prefer not to tie up assets. Practical definitions and examples of both secured and unsecured business loans are covered by the British Business Bank.

What is a secured business loan?

A secured business loan is backed by collateral, such as property, equipment, or inventory. This reduces lender risk and can unlock larger amounts, longer terms, and lower rates. A UK‑oriented comparison of secured and unsecured options is available from NerdWallet UK.

At a system level, secured finance relies on market‑standard collateral practices. For background on how a central bank treats collateral quality in its own lending operations, see the Bank of England guidance on eligible collateral.

Personal guarantees and liens
