Top 10 Lenders Offering a £150,000 Unsecured Business Loan in 2026

A £150,000 unsecured business loan gives your company access to a lump sum of working capital without having to put up property, equipment, or other business assets as security. You receive the full amount upfront — typically £150,000 — and repay it in fixed monthly instalments over an agreed term, usually between one and five years. Because there is no collateral, lenders assess your business's trading history, turnover, and credit profile instead. Interest is charged on the outstanding balance, and the rate you are offered will reflect the lender's assessment of risk.

Eligibility varies between lenders, but most will want to see that your business has been trading for at least two years, generates consistent monthly revenue, and has a reasonable credit history. Some lenders may accept younger businesses with strong turnover. Limited companies, LLPs, and in some cases sole traders can apply. Lenders will typically review your filed accounts, bank statements, and trading performance rather than asking for a personal guarantee or asset security — though some may still request a director's guarantee on larger unsecured facilities.

Interest rates on unsecured business loans generally sit higher than secured equivalents because the lender carries more risk. Rates can vary significantly depending on your business's credit strength, sector, and trading history. Repayment terms typically range from twelve months to five years, with some providers offering flexibility to extend. There may also be arrangement fees, typically a percentage of the loan amount. The total cost of borrowing will be shown clearly in your agreement, and UK-regulated lenders must present this as an annual percentage rate or total repayment figure.

The key difference is collateral. A secured business loan requires you to pledge assets — such as property, machinery, or vehicles — which the lender can claim if you default. This usually means lower interest rates and longer terms are available. An unsecured loan of £150,000 does not tie up your assets, making it faster to arrange and less risky for your balance sheet. However, you will likely pay a higher rate and may face a shorter maximum term. For many growing businesses, the speed and simplicity of unsecured finance outweigh the higher cost.

Start by comparing the total cost of borrowing — not just the headline rate but any arrangement, early settlement, or late payment fees. Look at the lender's track record with businesses of your size and sector. Check the speed of funding: some providers can release £150,000 within days, while others take weeks. Review whether a personal or director's guarantee is mandatory. Also consider flexibility — can you overpay without penalty, or access a top-up facility later? Finally, check that the lender is FCA-authorised or works with regulated partners for your protection.

Timescales depend on the lender and how prepared your paperwork is. Some online and fintech lenders can assess your application within hours and release funds in as little as 24 to 48 hours once approved. High-street banks and larger institutions may take one to four weeks, especially if they require in-depth underwriting, meetings, or additional documentation. Having your management accounts, bank statements, and financial projections ready can speed things up. Brokers who specialise in unsecured business lending can also help match you with a faster route to funding.
