DWP Document Error Fuels £370M UK Outsourcing Lawsuit
A DWP document shared in error is at the center of a £370M legal dispute over a major contract.
Why it matters: The mishap highlights growing risks of data leaks and process missteps in government outsourcing. Legal teams face mounting pressure to tighten data governance and vendor oversight on high-value public contracts.
- DWP accidentally sent a confidential bid comparison to incumbent provider SSCL in August 2025.
- The contract at stake: £370 million, awarded to Capita in early 2026—well below the £958.7 million initial estimate.
- Sopra Steria claims Capita’s bid was 'abnormally low' and alleges breaches of procurement rules.
- The case puts focus on procurement protocols and the risk of unintended disclosures in public-sector deals.
The UK’s Department for Work and Pensions (DWP) is under legal and public scrutiny after inadvertently disclosing a sensitive 'Comparison Document' that summarized rival bids for a lucrative Business Process Service (BPS) contract. The error, which occurred in August 2025, saw the document sent to an employee and a contractor at Shared Services Connected Limited (SSCL), a Sopra Steria subsidiary (The Register).
- The comparison chart detailed bids from Sopra Steria and Capita. Early in 2026, the DWP awarded Capita the £370 million BPS deal, a figure dramatically under the original £958.7 million maximum estimate. Sopra Steria, whose subsidiary SSCL was the incumbent provider, quickly mounted a legal challenge claiming Capita’s bid was 'abnormally low' and accusing the DWP of breaching UK procurement rules.
- Sopra Steria further alleges DWP renegotiated with Capita after their selection, potentially contravening standard procedures. The DWP insists the leaked document was produced after bid evaluation, solely to plan for transition—not for choosing a winner.
- The DWP and Sopra Steria had established an 'Ethical Wall Agreement' to prevent conflicts of interest. But the DWP claims the agreement was compromised when SSCL staff circulated the document within Sopra Steria, intensifying the legal fallout.
Both Capita and the DWP maintain that the procurement was robust and that public value remains the priority. However, the incident raises serious questions about data control in outsourced contracts and spotlights risks for public-sector legal, compliance, and procurement teams overseeing similar multi-million-pound deals. (Industry analysis)
By the numbers:
- £370 million — Total value of the Capita contract over ten years
- £958.7 million — Initial estimated maximum value for the BPS deal
- August 2025 — Timing of the DWP document disclosure
Yes, but: The full impact of the disclosure remains unclear, as details of the document's influence and the legal case outcome are still pending.
What's next: Pending court proceedings will determine if procurement rules were breached and what remedies may apply.
