Standard payment terms

Qualifying contracts for this entity contain a number of different payment periods: • Immediate • 30 days • 60 days • 45 days • 30 days and 5th of the following month • 60 days and 5th of the following month Payments are made from date of receipt of invoice.

Dispute resolution

We offer our suppliers the following support and service: • Enquiries and complaints can be logged through our Helpdesk support system (mail or telephone). Issues are often related to incorrect invoice submission, payment terms are not as per contract, PO details are wrong / nonexistent etc. Key performance metrics are monitored for quality of Helpdesk support. • Our Supplier web pages also include details and a link to our Speak Up channels that enable concerns to be raised, including channels managed independently of GSK and the option to do so anonymously, although naturally it helps in resolving matters if we know as much as possible about the issue and complainant. • We have invested in Customer Relationship Management (CRM) to ensure effective and independent supp

Other information

1) Statistics Reported: Intercompany invoices and performance have been excluded from reported statistics as these are generally wholly owned group companies and would distort performance if included. 2) Payment terms for SMEs and 'Paid on Time' monitoring: Preferential payment terms of 30 days are put in place for vendors that are confirmed as SMEs (Small and Medium Enterprises). We closely monitor our KPIs on a weekly basis to ensure that vendors (including SMEs) are paid on time. Corrective actions are taken to remedy any late payment issues where these are within the entity’s control.

Working-capital effect

What a 43-day cycle ties up

Illustrative. On a hypothetical £12k/month account, at a 43-day vs a 0-day payment cycle.

≈ £17,000
of invoicing outstanding at any one time on a 43-day cycle — about £17,000 more than the same account would carry at 0-day terms.

Late Payment Act. The Late Payment of Commercial Debts Act lets a supplier charge statutory interest and fixed compensation on invoices paid past agreed terms. Work out what a late invoice is worth → Whether it applies depends on your contract — check with an adviser.

How UK payment reporting works

What is a Payment Practices Report?
UK companies and LLPs above a size threshold — broadly, two of: turnover over £54m, balance sheet over £27m, or more than 250 employees — must report twice a year, under the Reporting on Payment Practices and Performance Regulations 2017, how quickly they actually pay suppliers: the average time to pay, the share of invoices paid in 30 days or fewer, 31 to 60 days and 61 days or longer, and their standard payment terms. Those thresholds apply to financial years beginning on or after 6 April 2025; for earlier financial years they were £36m and £18m, with the same 250-employee test.
What does "paid outside agreed terms" mean?
The share of invoices paid later than the terms in the supplier contract. If terms are 30 days and an invoice is paid on day 45, it counts as paid outside terms, regardless of the headline average.
How often is this data updated?
Each report covers a six-month period and must be filed within 30 days of that period ending, so a company's record refreshes roughly twice a year. PaidLate re-reads the register as new reports are filed.
Is this official government data?
The underlying payment figures come from the company's own statutory filings on the gov.uk payment-practices service; company-status data comes from Companies House. PaidLate calculates trends, comparisons and summaries from those records. It does not use surveys or credit-agency scores.

How this is compiled. Built from official records only: Companies House and the gov.uk payment-practices service. The payment figures are self-reported — companies over the size threshold must file them by law and the board signs them off. No credit-agency data. The numbers are theirs; the plain-English read is ours. This is information compiled from public records under the Open Government Licence v3.0 — not a credit rating and not advice.

The 31-day comparison figure is the median across 6,185 companies with a current statutory report — every sector pooled, not an average of sector medians (how the figure is built).
