Short answer
Yes. UK suppliers can use AI to support tender writing unless the procurement documents restrict it, but the bidder remains responsible for accuracy, confidentiality, intellectual property and compliance. Contracting authorities may ask bidders to disclose AI use. Use approved tools, keep sensitive tender material out of unapproved systems, ground drafts in verified evidence and require accountable human sign-off.
What current government guidance means for bidders
Cabinet Office guidance recognises that AI can improve bid-writing efficiency and allows authorities to include an AI-disclosure question in procurement documents. Disclosure is not automatically a penalty. The risk is undisclosed or uncontrolled use that creates inaccurate statements, mishandles confidential material or obscures who is responsible for the response.
Read the invitation to tender, portal instructions and any acceptable-use or confidentiality clauses. If the authority asks how AI was used, answer accurately: the task performed, the controls applied and the human review completed.
Good and poor uses
- Good: extracting requirements into a compliance matrix, provided the source is complete and the output is checked.
- Good: locating relevant approved evidence in a controlled content library.
- Good: producing a first structure or alternative wording for human editing.
- Poor: inventing examples, performance figures, policies or accreditations.
- Poor: uploading confidential procurement documents or personal data to an unapproved public tool.
- Poor: generating the full response and submitting it without operational, commercial and legal review.
A defensible AI-assisted workflow
- 1
Classify the material
Identify confidential, commercially sensitive, personal and authority-owned information before any tool is used.
- 2
Use an approved environment
Confirm contractual data handling, retention, training use, access controls and audit logs.
- 3
Ground the draft
Limit source material to current provider evidence and the procurement documents. Label unsupported gaps rather than filling them.
- 4
Verify line by line
Check requirements, names, dates, numbers, citations and every operational promise against authoritative material.
- 5
Record approval
Keep version history and named sign-off from the service, commercial and bid owners.
How to compare AI tender-writing products
A useful comparison goes beyond prose quality. Test requirement traceability, source citations, evidence permissions, version control, redaction, audit logs, export, model data handling and the ability to prevent unsupported claims. Ask the vendor to draft from a deliberately incomplete evidence pack; a trustworthy system should expose the gaps.
