How long do UK companies really take to pay? What statutory payment reports show

Information, not financial advice.

The median large UK company now takes 31 days to pay a supplier invoice. Across every report filed since the duty began in 2017, the median is 33 days. Both figures come from the full public register of statutory payment reports — 110,873 filings from 10,142 companies — which we pulled in full and totalled ourselves, because gov.uk publishes the raw reports but never adds them up.

Since April 2017, UK companies and LLPs within the reporting duty have been required to publish, twice a year, how they pay suppliers: average time to pay, the share of invoices paid in 30 days or fewer, and the share paid outside agreed terms. The size test is two of three — turnover over £54m, a balance sheet over £27m, or more than 250 employees — and those figures apply to financial years beginning on or after 6 April 2025; before that they were £36m and £18m, which is what most reports already on the register were filed under. Reports go onto a public government register. Here's what the whole of it shows.

The headline numbers: 31 days now, 33 days across nine years

Two figures, two different populations, and it matters which one gets quoted. Across every report in the register since 2017 the median "average time to pay" is 33 days; the mean is a bit higher, at 35.8 days, because a handful of companies' figures are pulled up by outliers (more on that below). Narrow it to where things stand now — one figure per company, counting only the 6,185 large firms whose most recent report covers a period inside the last fifteen months — and the median is 31 days. That's the number our own lookup runs on. The register has been speeding up, which is exactly why the nine-year figure sits two days above the current one.

Either figure covers everything from a construction firm on 30-day terms to a retailer with 90-day terms who pays right on time. Neither is a single "normal" number so much as a midpoint across a very wide spread of contractual terms and behaviour — which is exactly why looking up a specific company's own filing matters more than any national average.

It's been getting better, slowly

We grouped every report by the six-month period it covers and tracked the median time to pay and the share of invoices paid outside agreed terms from 2017 to now:

(2017-H1 and 2026-H2 are excluded from this table — the reporting duty had only just started in the first, and the second period is still open with most companies yet to file.)

Two things stand out. First, median payment time has drifted down from around 35–36 days to 31–32 days over nine years — not dramatic, but a real and fairly steady trend, not noise. Second, the share of invoices paid outside agreed terms has fallen further and faster, from a quarter of all invoices in 2017 to roughly one in six or seven today. Read together, that suggests large companies haven't necessarily shortened their payment terms much — they've gotten better at actually hitting the terms they set.

Whether that's driven by better AP systems, reputational pressure from having to publish these numbers at all, or just economic conditions is genuinely hard to say from this data alone. It's a correlation over time, not a proven cause.

The gap between the fastest and slowest payers is enormous

National averages hide a lot. Looking at the most recent complete reporting period — the six months to 31 March 2026, 1,143 filings — the spread is stark. The median for that period alone is 29 days, below both headline figures above. But at one end companies report paying effectively immediately, 100% of invoices within 30 days and an average time to pay in the low single digits; at the other, a handful report average payment times well over 100 days, with the majority of their invoices landing more than 60 days after they were due.

A few numbers from that period, taken directly from the statutory filings: the fastest reporting company had a 0-day average with 100% of invoices paid inside 30 days. The slowest reported a 225-day average, with two-thirds of invoices taking more than 60 days. Both figures are self-reported and neither is independently audited — but both are numbers the companies themselves chose to publish under a legal duty, which is a meaningfully different thing from a rumour or a review.

A note on data quality

This is a self-reported dataset with no independent verification layer, and it shows. In the course of this analysis we found 46 reports with an "average time to pay" figure that's obviously wrong — the most extreme being a well-known online retailer that reported an average of over four million days for one period, which is plainly a data-entry error, not a real payment time. A cluster of restaurant-group filings from the same historic ownership all show exactly "1000" days, which reads like a placeholder value that never got corrected. We excluded anything above 365 days from the mean figures above — the medians don't move either way, which is precisely why we lead with them; you should assume similar oddities exist elsewhere in the register at a smaller scale.

None of this means the dataset is unreliable as a whole — 110,000-plus filings is a large enough sample that a few dozen bad rows don't move the median. But it's a good reason not to take any single company's self-reported figure as gospel without a sanity check, and it's exactly the kind of thing that's easy to miss if you're pulling one company's report by hand rather than looking at the pattern across thousands of them.

Who actually has to report, and who doesn't

It's worth being clear about the scope, because it changes how you should use this data. The duty applies to UK companies and LLPs that, on their own or as part of a group, meet at least two of three thresholds: turnover above £54m, balance sheet total above £27m, or more than 250 employees. Those thresholds rose on 6 April 2025 from £36m and £18m, and once they rise the new figures are applied back over the two preceding years for the size test, so a business can drop out of scope without its own numbers changing. That's a high bar — it captures large corporates, well-known retailers, big infrastructure and utilities firms, large recruitment and construction groups, and so on, but it excludes the overwhelming majority of UK businesses by number. Most small and medium suppliers will never appear in this register themselves, and most of the customers a small business deals with day to day won't either.

What that means practically: this register is most useful when you're the smaller party supplying a large one — a subcontractor invoicing a national housebuilder, an agency staffing a listed company, a specialist supplier to a big retailer. If your customer is another SME, this particular register won't have anything on them, and you'd need to rely on the other free public sources (Companies House filing history, County Court Judgments, Gazette notices) instead — which we cover in a separate guide.

It's also worth knowing that reporting is mandatory but not really policed in the way you might expect. There's no independent verification of the figures before they're published, and while non-compliance is technically a criminal offence, enforcement in practice is limited. So a company appearing in the register with good numbers has told the government those are its numbers — that's more accountable than an unverified claim, but it's not the same as an audited financial statement.

Why this matters if you're the one waiting on an invoice

If you supply a large UK company, this register is the closest thing to a credit reference you'll get for free, straight from the source, with no sales call attached. Two things worth doing before you extend credit or agree terms with a new large customer:

Look up their actual filing history, not just their most recent report — a company that's been drifting slower over several periods is telling you something different from one that's had one bad quarter. And treat the headline "average time to pay" as a starting point, not the whole picture — the breakdown between invoices paid within 30 days, 31–60 days, and over 60 days tells you how consistent they are, which matters more than the average if you're trying to plan your own cash flow around them.

PaidLate does exactly this: it combines the statutory register with Companies House records in one free company lookup. Payment metrics appear where a qualifying company has filed a report; doing the same cross-check by hand for every customer is not realistic for most small suppliers.
