Winn Solicitors Limited reported an average of 81 days to pay its suppliers in the six months to 31 March 2026, with 23% of its invoices paid more than 60 days after it received them.
The next slowest were Industrial Turbine Company (UK) Limited at 72 days, Siemens Energy Industrial Turbomachinery Limited at 70 days, Siemens Energy Limited at 70 days and FMC Technologies Limited at 65 days (the six months to 30 June 2026). Those reports cover the six months to 30 September 2026 unless shown.
Across the 43 companies, the median company paid 62% of its invoices within 30 days, against 64% for all UK reporters. In all, one of the Newcastle companies said half or more of their invoices were not paid within the terms agreed with the supplier; the median share paid late was 15%, against 15% nationally.
The largest shares of invoices paid outside agreed terms were reported by Zentia Limited (92%), The Gosforth Federated Academies Limited (49%) and NorthStandard Limited (48%).
The fastest payers were Home Group Developments Limited, at 14 days; Atom Bank PLC, at 15 days; True Potential Administration LLP, at 17 days.
Of the 39 companies that also reported for a period ending about a year earlier, 16 were paying faster on average and 19 slower.
Construction and retentions
Of the Newcastle companies, 19 reported construction contracts in their latest period, and 12 said those contracts include retention clauses, which let the paying party hold back part of each payment until the work is finished or its defects period ends. The typical standard retention rate was 5%. Companies reporting retention clauses include Northern Powergrid Metering Limited, Northern Powergrid (Northeast) PLC and Northern Powergrid (Yorkshire) PLC (10% each). The construction and retention questions were added to the reports filed from July 2025, so they appear only in the most recent filings.
How the figures were worked out
Large companies and limited liability partnerships must publish their payment figures every six months under the Reporting on Payment Practices and Performance Regulations 2017. The figures here are what each company filed on the government’s Check payment practices service, published as open data under the Open Government Licence v3.0, as downloaded on 3 November 2026. Each company’s latest report is used, counting only reports for periods that ended on or after 4 May 2025. Companies are placed in Newcastle by the registered office address held by Companies House (data as at 1 September 2026), using postcode districts NE1 to NE7, NE12, NE13 and NE15. A registered office is where a company is registered, not necessarily where it trades or employs people. The median is the middle company when all are ranked. Reports with figures that cannot be right, such as an average above 365 days or a share above 100%, are left out. Figures for groups are as filed by each subsidiary.
