Terms of service

Last updated 27 September 2026

These terms are a working draft for the founding-member programme and will be reviewed by a solicitor before general launch.

1. Who we are

Tierline is provided by the company that operates Tierline (details to be published before general launch). In these terms, "we" means that company and "you" means the business that holds the account. Tierline is for business use only; by creating an account you confirm you are acting for a business, not as a consumer.

2. What Tierline does, and what it does not do

Tierline helps construction businesses manage payment applications, keep a qualification profile, and research companies, contracts and tenders using open public data. It works out dates and sums from what you enter and from the public record.

Tierline never sends, submits, signs or prices anything on your behalf. Letters and notices are drafts for you to check against your own contract and send yourself. Statutory dates and sums are calculated from the Housing Grants, Construction and Regeneration Act 1996 (as amended), the Scheme for Construction Contracts and the Late Payment of Commercial Debts (Interest) Act 1998, but a contract can set its own compliant terms, so you remain responsible for checking them.

Risk scores are indicators, not credit ratings or financial advice. They summarise public information (Gazette notices, Companies House filings, filed accounts, payment practice reports and public contract awards) and every point shows its source. They can be wrong or out of date. Do not rely on a score alone when deciding whether to trade with, lend to or pay anyone.

3. Your account

Keep your login details private and tell us promptly if you think someone else has used them. You are responsible for what is done through your account and for the accuracy of what you enter.

4. Your data

What you enter (projects, applications, payments, your profile and credentials) belongs to you. We use it only to provide Tierline to you, as described in our privacy notice. You can export it or ask us to delete it at any time.

If you switch on payment sharing for a project, we add one anonymous record of how that client paid (days to pay, whether in full, whether a valid pay-less notice was given, and a value band) to Tierline's payment record. It is only ever shown combined with reports from at least three different members and is never attributed to you. You can switch sharing off for any project.

Profiles you share are visible only to the signed-in users whose email addresses you add, until you remove them.

5. Acceptable use

Do not use Tierline to harass or defame anyone, to send unsolicited marketing in breach of the Privacy and Electronic Communications Regulations, to scrape or resell the service or its data in bulk, to try to identify the members behind anonymous payment figures, or to break the law. We may suspend accounts that do.

6. Trials, plans and payment

New accounts get a 30-day free trial. After that, paid features need a plan. Prices are shown on the pricing page and exclude VAT. Subscriptions renew automatically each month or year until cancelled; you can cancel at any time and keep access until the end of the period you have paid for. We will give at least 30 days' notice of any price change.

7. Public data

Much of Tierline is built on information published by public bodies under the Open Government Licence v3.0 or similar terms. We do not guarantee that source data is complete or correct, and some sources publish late. The data sources page shows what we read and when it was last refreshed.

The open licences cover the source records, not Tierline's own work on them. How records are matched to companies, the risk scores and their reasons, the track record and the member payment record are Tierline's own, protected by copyright and database right. You may use what you see to make your own business decisions. You may not extract or re-use all or a substantial part of it, including by repeated extraction of smaller parts, or use it to build or feed a competing service. Automated and bulk access is limited, and accounts that try to get round the limits will be closed.

8. Availability

We aim to keep Tierline available and your data safe, but we do not promise uninterrupted service. Keep your own copies of documents you send. We may change features, and we will tell you in advance about changes that materially reduce what you pay for.

9. Liability

Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for anything that cannot be limited by law. Otherwise, we are not liable for loss of profit, revenue, contracts or business, or for indirect loss, and our total liability in any 12 months is limited to the fees you paid us in that period. You are responsible for decisions you make using Tierline.

10. Ending your account

You can close your account at any time. We may close it on 30 days' notice, or immediately for a serious breach of these terms. When an account closes we delete your data within 90 days, except records we must keep by law. You can delete your account yourself at any time in Settings, which removes your data immediately.

11. Law

These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction.
