The Fair Payment Code has been operating for a year. The early sceptical case was that voluntary codes do not move the median because they rely on reputation in a market where reputation is poorly signalled. The early supportive case was that this Code was structurally stronger than its predecessors, because it carries published behavioural data and a tiered membership structure that rewards demonstrable performance. A year in, both cases deserve revisiting against the data.
What the Code set out to do
The Fair Payment Code launched with three explicit goals.
Move the median UK business payment behaviour by making compliance with stated terms a published, verifiable commitment.
Create a tiered structure (Gold, Silver, Standard) that allows businesses to differentiate themselves on payment performance, with public consequence for non-compliance.
Build the evidence base for a possible future move from voluntary to enforceable, by demonstrating what compliance and non-compliance look like in practice. We argued this trajectory in Fair Payment Codes without enforcement will fail.
The original sceptical case argued that the first goal would not be met because the voluntary architecture did not carry enough enforcement weight. The supportive case argued that the second goal was new and material, and would itself create the conditions for the third.
What the data shows after a year
Three observations from the first year, drawing on the UK Industry Benchmark and the Code's published reporting.
Signatory behaviour has improved measurably. Businesses that signed in the first six months show a median improvement of 4 to 7 percentage points in payment timeliness against terms, compared to a control group of similar non-signatories. The improvement is not uniform across sectors and is concentrated in mid-market signatories rather than the largest groups.
The median across non-signatories has not moved. The Code's effect, where it is present, is concentrated among signatories. The broader market has not responded.
The tiered structure is producing differentiation. Gold-tier signatories perform meaningfully better than Silver, which perform better than Standard. The tiering is not cosmetic. It is reading as a commitment that translates into observed behaviour. This is the same discipline we apply to supplier trust scoring: a public commitment loses value where it cannot be evidenced.
Where the Code is moving the needle
Three patterns are evident.
Procurement gates. A growing number of public sector and ESG-conscious private sector buyers are reading Code membership tier as a procurement criterion. The commercial consequence of tier status is becoming real, which is what the Code's architecture was designed to produce. This direction sits inside the wider policy momentum in the UK government's late-payment crackdown.
Internal accountability. Finance leaders at signatory businesses report that Code membership has changed internal conversations. Payment performance is a board item where it was previously an operational one. The Code provides language and structure for that conversation.
Supplier engagement. Suppliers increasingly ask buyers about their Code status during commercial discussions. The Code has become a recognisable signal that suppliers use to inform their own commercial decisions, particularly around payment certainty. This is the practical expression of payment behaviour as underwritten rather than promised.
Where it is not
The Code has not changed the behaviour of businesses that have not signed. The non-signatory population has multiple sub-segments, including businesses whose performance would not qualify for any tier and businesses that have not engaged with the policy conversation at all. Neither has shifted in response to the Code's first year.
The Code has also not addressed sector-specific structural lateness. Construction, hospitality and retail remain in the bottom quartile of UK sectors regardless of individual signatory status. The structural drivers in these sectors (contract chains, certification cycles, asymmetric leverage) sit beneath the voluntary architecture.
What evidence-based compliance now looks like
The Code's structure invites a step from declared compliance to evidenced compliance. Three components are emerging.
Network-sourced behavioural data, used to verify the signatory's actual performance against the tier they claim. Where the data sits independently of the signatory, the claim is auditable in the way an emissions claim is auditable. Built-in Fair Payment Code compliance shows what this looks like inside the workflow.
Public reporting against tier criteria, with the underlying data accessible to interested parties. The Code already publishes; the depth of the publication is expanding.
Independent review, where third parties assess the signatory's behaviour against the tier definition. The audit-grade review is still emerging, but the architecture supports it.
The path from voluntary to enforceable
The trajectory from voluntary code to enforceable standard is well-documented across other policy areas. The Code's first year has produced the evidence base that a future enforceable framework would draw on.
Three preconditions for enforcement are in place.
Defined behavioural standards. The tier definitions are specific and measurable.
Verifiable performance data. Network-level behavioural data exists and is improving in coverage.
Sectoral pattern visibility. The data surfaces where the median sits, which sectors are above and below, and which structural factors drive the variance.
An enforceable framework would build on these and add consequence: penalties for non-compliance, mandatory disclosure for businesses above a size threshold, and procurement gating in public sector contracting. The architecture exists. The political decision to move to enforcement is the remaining variable.
What businesses should prepare for
Three preparation moves are sensible for finance leaders in 2026.
Sign the Code at a tier the business can actually evidence. Tier inflation will be visible when the audit-grade review framework matures. Signing high and underperforming is worse than not signing at all.
Build the data architecture that makes evidenced compliance possible. Network-sourced behavioural data is the foundation. Businesses that have it in place will navigate any future enforceable framework with less friction.
Engage with the policy conversation. The Code is evolving. Finance leaders who want to shape the next iteration have more leverage now than they will once the framework moves toward enforcement.
