Search UK public tenders with AI
UK public procurement is split across two official systems — Find a Tender for higher-value contracts and Contracts Finder for lower-value and below-threshold work. TenderStack searches both at once, with AI semantic search and who-won data, from inside the AI tools you already use.
Both UK portals, one search
- Find a Tender Service (FTS) — the UK's portal for above-threshold public contracts.
- Contracts Finder — lower-value and below-threshold opportunities, plus contract awards.
Checking only one of these is a common way to miss work. Larger framework opportunities live on Find a Tender; a lot of the accessible, lower-competition contracts — especially for SMEs — sit on Contracts Finder. TenderStack queries both in a single request.
Search by what you do, not by code
Instead of filtering on CPV codes, describe your business in plain English and let semantic search rank results by fit. Ask "open facilities-management contracts in the North West under £500k" or "NHS digital-health tenders closing in the next 30 days" and get ranked, summarised results.
Competitive intelligence
UK award notices in TenderStack carry the winning supplier and contract value where published. Use that to see who holds the contract you want, what it paid, and — with the forecasting tools — when similar contracts are likely to return to market. History runs back to 2023.
One UK view alongside the EU and US
Many UK suppliers also bid into the EU and the US. TenderStack keeps all three in one place: UK here, plus EU tenders via TED and national portals and US federal contracts and grants. It runs in Claude, ChatGPT and the web app, refreshed every 8 hours. Setup is in the docs.

What's the difference between Find a Tender and Contracts Finder?
Find a Tender (FTS) is the UK's portal for higher-value, above-threshold public contracts. Contracts Finder carries lower-value and below-threshold opportunities and contract awards. TenderStack searches both at once, so you don't have to check two systems.
Can I find below-threshold UK contracts?
Yes. TenderStack covers below-threshold UK contracts via Contracts Finder alongside above-threshold notices from Find a Tender — useful for SMEs chasing smaller, less-contested work.
How do I see who won a UK public contract?
TenderStack stores UK award data, including the winning supplier and contract value where published, so you can research incumbents and benchmark pricing. History goes back to 2023.
Does it work in ChatGPT and Claude?
Yes. The same API key works in the TenderStack GPT for ChatGPT, the MCP server for Claude, and the web app. The free plan includes 200 actions a month; Pro is $49/month unlimited.
