FacFlow is available through both NatWest (England and Wales) and Royal Bank of Scotland (Scotland) brands, with a minimum turnover of £300,000 for invoice discounting and £6.5 million for asset-based lending. This is our independent review for 2026, including an important clarification on entity changes – NatWest Invoice Finance Limited was dissolved in June 2024, but the operating company RBS Invoice Finance Limited remains fully active.
- Advance rates up to 85% - Competitive funding levels backed by major banking group financial strength and stability
- Best for existing NatWest customers - Integrated banking relationships provide streamlined setup and preferential pricing access
- Confidential invoice discounting focus - Specialises in discrete facilities where clients maintain customer relationship control
- Minimum £1M turnover required - Higher entry threshold than Bibby but lower than Close Brothers’ requirements
- Bank-backed security - NatWest Group ownership provides stability but potentially slower decision-making than independents

FacFlow Products
FacFlow offers two core products: (1) Invoice Discounting – a confidential facility allowing businesses to draw funds against their sales ledger via the FacFlow digital portal; your customers are unaware of NatWest’s involvement and pay you directly. (2) Asset Based Lending (ABL) – a multi-asset facility for larger businesses (£6.5 million+ turnover) combining invoice discounting with borrowing against stock, plant and machinery, property, or other business assets. ABL is typically used for M&A, management buyouts, or significant capital requirements where the combined asset base supports a larger facility than invoices alone.
The FacFlow portal is the primary interface for managing your facility. It allows you to upload invoices, request drawdowns, monitor your ledger balance, and view funding status – all online without needing to contact a relationship manager for routine transactions. NatWest positions this as 100% paperless, with all credit advice and payment requests handled digitally.
For businesses with international receivables, FacFlow supports multi-currency funding – you can draw against invoices denominated in foreign currencies. This is particularly useful for exporters who invoice in euros or dollars but need sterling working capital.
NatWest Invoice Finance Entity Clarification
An important clarification for 2026: NatWest Invoice Finance Limited (Company No. 04199792) was dissolved on 11 June 2024 – but this was a non-trading shell entity, not the operating business. The operating company, RBS Invoice Finance Limited (Company No. 00662221), remains fully active with accounts filed to December 2024. The FacFlow product is unchanged. NatWest Group transferred from the RBS Group brand to NatWest Group on 22 July 2020, but the operating invoice finance subsidiary retained its RBS Invoice Finance Limited name. Both the NatWest and RBS-branded interfaces lead to the same underlying facility provider.
If you search for NatWest invoice finance on Companies House, you will find two entries: the dissolved NatWest Invoice Finance Limited and the active RBS Invoice Finance Limited. This has caused confusion in the market, with some comparison sites incorrectly reporting that NatWest has exited invoice finance. The FacFlow product continues unchanged under the RBS Invoice Finance Limited entity, which has continuous accounts filed since incorporation. Our Best Invoice Finance Companies UK 2026 covers this in depth. We explore this further in our Invoice Discounting UK. For alternatives, see our Close Brothers Invoice Finance Review.
Is NatWest FacFlow Right for Your Business?
NatWest FacFlow is best suited for established UK businesses with £300,000+ annual turnover that want invoice discounting from a major bank group – particularly if they already bank with NatWest or Royal Bank of Scotland. The £300,000 minimum is lower than many institutional providers (Close Brothers requires £500,000), and the FacFlow digital portal offers a more self-serve experience than traditional relationship-managed facilities. It is not suitable for startups, sole traders, or businesses needing invoice factoring (FacFlow is discounting-only – you retain credit control). The NatWest overall Trustpilot rating of 1.4/5 reflects retail banking complaints and should not be applied to the B2B FacFlow product.
FacFlow Fees and Rates
NatWest does not publicly disclose FacFlow pricing. As with most bank-backed invoice finance facilities, fees comprise a discount charge (interest on the advanced balance, expressed as a margin above the Bank of England base rate) and a service charge (percentage of annual turnover). Bank-backed providers typically offer lower discount rates than independents – expect a margin of 1.75–2.5% above base rate for invoice discounting. The service charge for confidential discounting is usually 0.1–0.5% of turnover.
NatWest’s pricing advantage comes from its cost of capital – as one of the UK’s largest banks (backed by the UK government holding through UKGI until 2024), it can fund facilities more cheaply than independent providers. The trade-off is less flexibility: bank-backed facilities typically have longer setup times, more rigorous due diligence, and less willingness to fund riskier sectors or debtor profiles.
