Tierline works out every Construction Act date on your payment applications, drafts the reminder and interest letters, and warns you the day a client shows signs of failing. Construction has more company insolvencies than any other industry in England and Wales: over 3,800 in the last year. Every warning is built from public awards, Gazette notices, filed accounts and payment reports, and every point links to its source.
Built only on open public data. Indicators to support your own checks, not credit ratings.
Counted on 26 September 2026. Tenders and Gazette notices refresh daily; company records monthly.
A tested chance of insolvency, filed accounts, Gazette notices and real payment behaviour on any firm you work for, plus a suggested ceiling on how much unpaid work to carry.
For every open tender: the likely incumbent, how risky they are, how many bidders this buyer usually attracts, and who it tends to award to.
Contracts ending in the next two years, major planning schemes before a contractor is named, and subcontract packages from nearby awards.
Payment applications with every Construction Act date worked out, notices tracked, and the reminder, statutory-interest claim and notice to suspend drafted for you to send. One cash view of what you're owed and which clients put it at risk.
A tested chance of insolvency in the next 12 months for every contractor winning public work, with the warning signs behind it: Gazette notices, late filings, filed accounts, payment behaviour and workload against size. Every sign links to its source.
Every open construction tender, with who holds the work now and how risky they are, how many bidders this buyer usually gets, and a bid/no-bid score for your firm.
Not just public-sector winners: any of ~592,000 UK construction companies. Insolvency status, charges, previous names, and phoenix signals before you sign.
Statutory payment reports plus how members were actually paid: days to pay, pay-less notices, retention. Figures appear only when 3+ firms have reported.
Contracts ending in the next 6–24 months, with the re-procurement stage and a flag when the incumbent is showing distress.

The failure probability is fitted on what happened to contractors in 2023 and 2024, using only what was public at the time, then scored on 18,293 firm-years in 2025. The tenth it rated riskiest held 31% of the 227 insolvencies that followed. Higher ratings meant more failures:
| Rated | Under 1% | 1–2% | 2–5% | Over 5% |
|---|---|---|---|---|
| Actually failed | 0.8% | 1.7% | 5.3% | 6.5% |
A live winding-up petition is handled from the whole Gazette record: 80% of the 11,127 companies petitioned between 2022 and 2025 were in insolvency within a year. Most firms that fail show little in public beforehand, so read the probability as a level, not a verdict.
A company set up to carry on a failed firm's business is flagged from Gazette prohibited-name notices, and close name matches set up nearby soon after a failure are raised as questions to check.
The one dataset nobody can buy: how contractors actually pay their supply chain. Anonymous, shown only in aggregate once three or more firms have reported.
