Is invoice factoring legal in the UK?

26th March 2026

By Simon Carr

TL;DR: Yes, invoice factoring is entirely legal in the UK and is a widely used method of business finance. While it provides immediate cash flow, businesses should be aware of the costs and the potential impact on customer relationships if the lender manages the sales ledger poorly.

Is invoice factoring legal in the UK?

Invoice factoring is a common and legitimate financial practice used by thousands of businesses across the United Kingdom. It is a form of asset-based lending where a business sells its accounts receivable (unpaid invoices) to a third-party financial company, known as a factor. This allows the business to access cash immediately rather than waiting 30, 60, or 90 days for customers to pay.

In the UK, this practice is governed by long-standing contract laws and specific regulations designed to support business growth. Because it is a commercial transaction between two businesses (B2B), it does not typically fall under the same consumer credit regulations as a personal loan, but it is still subject to strict legal frameworks.

The Legal Framework of Invoice Factoring

The legality of invoice factoring is rooted in the Law of Property Act 1925. Specifically, Section 136 of this Act allows for the “legal assignment” of a debt. This means that a business has the legal right to transfer the ownership of a debt (the money owed by a customer) to another party. For the assignment to be legally binding, it must be made in writing, and the customer (the debtor) must be notified of the change.

For many years, some large companies included “ban on assignment” clauses in their contracts. These clauses were designed to prevent small suppliers from using invoice factoring. However, the UK government introduced the Business Contract Terms (Assignment of Receivables) Regulations 2018 to tackle this. These regulations generally make such bans unenforceable for most commercial contracts, ensuring that small and medium-sized enterprises (SMEs) can legally access the finance they need to manage their cash flow.

Is Invoice Factoring Regulated?

It is important to understand that invoice factoring is not currently regulated by the Financial Conduct Authority (FCA) in the same way as residential mortgages or consumer credit. This is because factoring is considered a business-to-business (B2B) commercial service rather than a consumer product.

However, this does not mean the industry is a “Wild West.” Most reputable factoring providers in the UK are members of UK Finance. Members must adhere to a strict Standards of Good Practice and a Code of Conduct. This code ensures that lenders behave professionally, treat customers fairly, and provide transparent pricing. If a business has a dispute with a lender that is a member of UK Finance, they may have access to an independent complaints procedure.

How the Process Works Legally

When you enter into a factoring agreement, you are signing a legally binding contract. The process typically follows these steps:

  • The Agreement: You sign a contract with the factor, outlining the fees, the percentage of the invoice value they will advance (typically 70% to 90%), and the terms of the service.
  • Invoice Submission: You provide goods or services to your customer and send them an invoice. You then send a copy of that invoice to the factoring company.
  • The Advance: The factor pays you the agreed percentage of the invoice value, usually within 24 hours.
  • Credit Control: In a standard factoring arrangement, the factor takes over the sales ledger management. They will contact your customers to ensure the invoices are paid on time.
  • Final Payment: Once the customer pays the factor in full, the factor pays you the remaining balance of the invoice, minus their agreed fees.

During this process, lenders will often check the creditworthiness of both your business and your customers. They may also look at the credit history of the business directors.

Recourse vs. Non-Recourse Factoring

From a legal and risk perspective, there are two main types of factoring: recourse and non-recourse. Understanding the difference is vital for any business owner.

Recourse Factoring

This is the most common type of factoring in the UK. Under a recourse agreement, if your customer fails to pay the invoice (perhaps due to insolvency or simple refusal), your business is legally responsible for buying the debt back from the factor. This means the risk of “bad debt” remains with you.

Non-Recourse Factoring

In a non-recourse agreement, the factoring company assumes the credit risk. If the customer does not pay for specific reasons (usually insolvency), the factor absorbs the loss. Because the factor is taking on more risk, this service typically comes with higher fees and may require you to take out credit insurance.

Potential Risks and Considerations

While invoice factoring is legal and beneficial, it is not without risks. It is a commercial commitment that should be entered into with a clear understanding of the consequences.

Firstly, there is the cost. Factoring fees usually consist of a service fee (for managing the ledger) and a discounting fee (similar to interest on the money advanced). These costs can add up and may reduce your overall profit margins. You should always compare the cost of factoring against other forms of finance, such as business loans or overdrafts.

Secondly, there is the element of control. Because the factor manages your credit control, they will be the ones speaking to your customers. If the factor uses aggressive collection techniques, it could potentially damage your relationship with your clients. It is often wise to choose a factor that understands your industry and maintains a professional tone.

Finally, some factoring agreements may require a Personal Guarantee (PG) from the business directors. This is a legal promise that if the business cannot meet its obligations to the factor, the director will pay from their personal funds. If a Personal Guarantee is supported by a charge over your home, your property may be at risk if repayments are not made. Possible consequences of failing to meet these obligations include legal action, repossession of the property, increased interest rates, and additional charges from the lender.

Is Invoice Factoring Right for Your Business?

Whether invoice factoring is a “good” legal choice depends on your specific circumstances. It is generally most useful for businesses that:

  • Have a high volume of B2B invoices.
  • Experience long payment terms that restrict cash flow.
  • Are growing rapidly and need working capital to fulfil new orders.
  • Do not have a dedicated internal credit control department.

However, if your business has very low profit margins, the cost of factoring might outweigh the benefits. Similarly, if your customers are sensitive about third parties managing their accounts, you might prefer “invoice discounting,” where the facility remains confidential and you keep control of your sales ledger.

People also asked

Is invoice factoring the same as a loan?

Not exactly; while both provide cash, factoring is the sale of an asset (an invoice) rather than borrowing a lump sum that must be repaid in monthly instalments.

Can a company stop me from factoring their invoices?

In the UK, the 2018 Assignment of Receivables Regulations generally prevent companies from banning the assignment of invoices, though some exceptions apply for very large contracts or specific industries.

What happens if my customer goes bust?

If you have “recourse” factoring, you will typically have to pay the money back to the factor; if you have “non-recourse” factoring, the factor usually covers the loss.

Do customers know I am using a factoring service?

In standard factoring, yes, because the factor handles the collection and the invoice will usually bear a “notice of assignment” telling the customer where to pay.

Is invoice factoring expensive?

Costs vary depending on your turnover and the creditworthiness of your customers, but it is often more expensive than a traditional bank loan due to the added service of ledger management.

Conclusion

Invoice factoring is a perfectly legal, well-established, and highly regulated industry in the UK. It provides a vital lifeline for businesses that need to bridge the gap between completing work and getting paid. By understanding the legal framework, such as the Law of Property Act and the 2018 Assignment Regulations, business owners can use these tools with confidence.

As with any financial product, the key is to read the contract carefully, understand the fees, and consider the potential impact on your customer relationships. By choosing a reputable provider, typically one aligned with UK Finance standards, you can ensure that your business remains on a solid legal and financial footing while accessing the capital it needs to thrive.
