About Tenderline
UK procurement intelligence · operated by Vivid Analytics Ltd, England & Wales company 16555468 · independent
Tenderline is a UK procurement intelligence company. Its public platform turns official open procurement data into the read a bid team actually needs: live tenders and planning notices, contracting authorities and awarded suppliers, and on each page the competition context that a notice never gives you: who you are likely to meet, how awards land against the published estimate, who usually wins, which contracts are ending and which similar opportunities are open right now. The public platform is where we start, not what we are.
Who runs Tenderline
Tenderline is developed and operated by Vivid Analytics Ltd, a private limited company registered in England and Wales, company number 16555468, incorporated on 2 July 2025. Its registered office is 58 New Bedford Road, Luton, Bedfordshire, LU1 1SH, United Kingdom. The company's registered activities are software development, IT consultancy and data processing; its filings are public at Companies House.
The platform is built by a team with long hands-on experience of running and bidding for public tenders on both sides of the table. That is why the numbers are organised around the decisions a bid team actually makes (is this contest worth entering, who will I meet, where do awards land against the estimate, when does the incumbent's contract end) rather than around the shape of the source data.
What the platform adds
Official notices are the raw material, not the product. Tenderline compiles them per procedure, resolves organisations into one profile each (whatever a notice called them), keeps lots as the unit of competition and awards as the unit of money, and then computes what a bid manager asks first: how many bids a lot usually draws here, how awards compared with the published estimate, who wins in this market, when the incumbent's contract ends, and which live notices resemble this one. Search by keyword, sector, region or portal; open any notice for its evaluation weights, the submission route and the authority's track record.
Every computed figure carries an that says how it was arrived at and what that page's own sample was; the counting rules are public on the methodology page. Where the evidence is thin, a figure is muted or withheld rather than invented.
Where Tenderline is going
The public platform is the open layer of a commercial procurement-intelligence business. The record is growing beyond its first source, starting with Contracts Finder, and the product will change with it: features, coverage and how they are offered may change as the business develops.
How we work
- Independent. Not affiliated with, endorsed by, or operated on behalf of the Cabinet Office, Find a Tender, Contracts Finder, any contracting authority, e-sourcing portal or supplier.
- Source first. Every tender page links to the official notice it was built from.
- Units kept apart. Procedures, lots and awards are counted separately; frameworks and dynamic markets apart from contracts; a ceiling is not presented as a price.
- Facts, derived figures and model estimates are labelled as such, with their window and sample size next to them.
- Corrections. When our figure is wrong we fix our figure; the official notice stays as its publisher wrote it.
Where the data comes from
Tenderline is built from official UK public procurement notices published as open data under the Open Government Licence v3.0. Today the catalogue carries Find a Tender notices, and more sources are being added. Organisations are matched against official registers such as Companies House. Crown copyright applies to the notice data. Notices are synced through the day, recompiled per procedure as amendments and awards arrive, and the figures are rebuilt nightly.
On top of the record Tenderline adds structure, links and derived intelligence. It does not create or verify information that is absent or wrong at source: a value, date or supplier name is what the contracting authority published, normalised but not invented.
Corrections
If a figure or a record looks wrong, write to hello@tenderline.uk with the page URL and, where possible, the notice reference. We recheck against the source notice and correct our figure where it is wrong. Corrections to the notice itself belong with the contracting authority that published it.
Authorities and suppliers who want their profile reviewed (a merged organisation, a renamed body, a duplicate registration, a mis-attributed award) can use the same address.
