Questions & Answers
Lucius AI reads a public-sector tender pack and extracts every requirement into a register, providing a citation to the page each requirement comes from. It then builds a compliance matrix from that requirement register, which bid managers can export directly to Word, Excel or PDF.
The State of Defence Procurement in UK
Updated
UK defence procurement rules and sources
The Procurement Act 2023 applies to procurements started on or after 24 February 2025 by contracting authorities in England, Wales and Northern Ireland, and by UK-wide public bodies. Notices under the Procurement Act 2023 are published on Find a Tender, the UK government's central digital platform. Meanwhile, procurements that started before 24 February 2025 continue under the Public Contracts Regulations 2015 until they finish. Devolved Scottish public bodies are not covered by the Procurement Act 2023; they buy under the Procurement Reform (Scotland) Act 2014 and the Public Contracts (Scotland) Regulations 2015.
For the UK, the Lucius catalog indexes open notices from: Find a Tender, Contracts Finder, Public Contracts Scotland, TED. Lucius AI also keeps a live index of 230,000+ public tenders from 15 official sources in 170+ countries, allowing bid teams to track relevant defence opportunities as they appear.
Market activity and defence response timelines
On 24 September 2026, across the whole UK, the catalog held 20 open notices whose text mentions defence, drawn from Find a Tender, Contracts Finder and TED. Across all sectors, 1,654 notices were open in the same scope. Defence tenders present demanding deadlines for submission teams.
Of those 20 notices, 10 (50%) were due to close within 30 days, and the median time left before the deadline was 32 days. Because half of these notices close within a month of viewing, teams require early reviews of every uploaded document.

Bid management workflows and Lucius AI capabilities
Bid managers lead the decision on whether to bid, own the compliance matrix, and plan the submission. They assign questions to contributors, track progress to the deadline, raise clarification questions within the clarification period, and review contract and commercial terms with the commercial or legal lead before sign-off.
Lucius AI reads a public-sector tender pack and extracts every requirement into a register, with a citation to the page each requirement comes from. Lucius AI builds a compliance matrix from that requirement register. The software also scans the contract terms for commercial risk, such as liquidated damages, liability caps and indemnities, helping bid managers review terms with commercial leads. To support initial qualification, Lucius AI gives a bid/no-bid verdict on the tender.
Drafting from past bids and exporting deliverables
Once requirements are established, bid managers must assemble responses across the technical and commercial sections of the tender. Lucius AI drafts responses from the company's own past bids, kept in its Bid Library. This allows bid teams to base their new proposal material on established material approved in earlier competitions.
When drafts and matrices are complete, the software exports its work to Word, Excel and PDF. Teams can then circulate matrices in spreadsheets or finalise narrative documents in standard office formats for final sign-off.
Bidders into UK defence contracts compete under Find a Tender, Contracts Finder, JCT/NEC4 frameworks and Crown Commercial Service agreements. Sector-specific compliance bars include List X / Facility Security Clearance (FSC), DEFCON terms, JSP 440 + JSP 604 alignment and ITAR/EAR awareness. When a tender asks for any of them, Lucius lists that requirement with its page and a quote from the source.
