Terms of Service

Last updated: 7 May 2026

The plain-English summary. We find cheaper rail-fare opportunities by querying public booking systems on your behalf. You decide whether to act on them and book directly with the train operator. We don't sell tickets, we can't refund tickets, and we can't help with delays - those are between you and the operator. Prices and availability change in seconds, so always verify on the operator's site before paying.

1. Acceptance of these terms

By using clerkenwelltrains.co.uk ("the service") you agree to be bound by these terms. If you don't agree, please don't use the service. We may update these terms from time to time - see section 13 below.

2. Who we are

The service is operated by Jade Browser Limited, a company registered in England and Wales. Registered office: Central Court, 25 Southampton Buildings, Holborn, London, WC2A 1AL. Contact: jadebrowsercontact@gmail.com.

3. What the service is, and what it isn't

What it is: a price-discovery and journey-planning tool for UK rail travel. We query the same public booking systems the train operators use to surface live fares, identify cheaper split-ticket combinations where they exist, and suggest the cheapest day to travel.

What it isn't:

We are not a ticket retailer. We do not sell rail tickets, take payment for the rail fare, or issue rail-fare receipts. The rail-fare booking happens on an official National Rail ticket retailer's website after you click Continue.
We do not currently charge a service fee - the service is free to use. You pay only the rail fare, through an official National Rail ticket retailer, at the price shown with no markup from us. We may introduce a small optional service fee in future; if we do, these terms will be updated and any charge will be shown to you before you pay.
We are not a travel agent. We don't bond passengers, hold deposits, or carry IATA / ABTA / ATOL membership.
We are not a transport operator. We don't run trains and we have no role in delays, cancellations, or service changes.

4. Age requirement

The service is intended for users aged 13 and over. If you are under 13, please use the service only with the supervision of a parent or guardian.

5. What you can expect from us

We will display fares as they appear on the train operators' booking systems at the time we fetch them. We update prices on each search, not from a stale cache.
We will identify split-ticket combinations only where the booking systems confirm a valid through-train calling at each ticket boundary.
We will not show you adverts, sponsored results, or operator-influenced ranking. We surface the genuinely cheapest fares and split-ticket combinations, wherever they come from.
We will run the service as best we can but cannot guarantee uninterrupted availability - see section 9.

6. What we expect from you

Use the service for personal travel research, not for automated harvesting, scraping, reselling, or commercial price-feed redistribution. Bulk programmatic access is reserved for an explicit API agreement which we don't currently offer.
Don't probe, attack, or attempt to circumvent the rate limits or security controls on the service.
Don't use the service to plan or commit fraud (e.g. buying split tickets you knowingly intend to use on services that don't call at the boundary station).
Verify each booking on the operator's site before you pay. See section 7.

7. Split tickets - your responsibility

Split-ticket savings exist because the British rail-fare regulations price journeys non-linearly. They are entirely legal, but they come with rules that you (not we) are responsible for following.

The single rule that matters most is this:

Each ticket is only valid if the train you are on calls at that ticket's boundary station as a public calling point. You don't have to get off - but the train must be timetabled to stop and let passengers on or off there.

Our planner only proposes splits where the booking systems confirm a valid calling pattern at the time of search. Real-world risk: rolling-stock substitutions or last-minute timetable changes can occasionally remove a calling point after we've shown you the split. If you hold split tickets and the train is short-formed or has a calling-point change, your ticket may not be valid for the journey.

We strongly recommend keeping a screenshot of the train's calling-pattern at booking time so you can demonstrate the split was valid when bought. The Rail Delivery Group's standard fare regulations honour reasonable-belief at time of purchase.

8. Booking and payment

In the current free-to-use phase, the only payment involved in a booking is the rail fare itself:

Our service. Free to use - we do not currently charge a service fee, and we never take your card details. If we introduce an optional service fee in future it would be collected via Stripe Checkout (Stripe acting as merchant of record) and shown to you before you pay.
The rail fare. Paid on the train operator's (or rail retailer's) own site after you click Continue. That contract is formed between you and them; their terms apply. We have no access to those payment details and no ability to refund or alter that booking.

If you have problems with the rail-fare booking - wrong train, no confirmation email, rail-fare refund request, delay-repay claim - please contact the booking site or train operator directly. Their customer-service teams hold that data; we don't.

We don't currently take any payment from you, so there is nothing for us to charge or refund on our side. For anything else, contact us at jadebrowsercontact@gmail.com.

9. Warranty and disclaimers

The service is provided "as is" without warranties of any kind, express or implied. In particular:

Fare accuracy. We display fares as we receive them from the train operators. Prices change in seconds and the booking site is the authoritative source - what you pay is what they charge, not what we showed.
Availability. Live fares assume seats remain available; advance fares can sell out between display and click-through.
Validity. Split-ticket validity depends on the train calling at the boundary stations as a public stop (see section 7). We do our best to filter to valid splits, but transient calling-pattern changes can occur after we've shown you the option.
Continuity. We may suspend or change the service at any time, including taking it offline for maintenance, regulatory compliance, or operator-API changes.

10. Limitation of liability

To the maximum extent permitted by English law, our liability to you in connection with the service is limited as follows:

We are not liable for indirect, consequential, or special losses (including missed connections, lost business, or loss of enjoyment).
We are not liable for losses arising from your booking on a third-party site, from third-party site outages, from operator service changes, or from invalid travel where the cause is a calling-pattern change after we proposed a split.
Where we are liable for direct losses, our aggregate liability is capped at £100 per user per twelve-month period. The service is provided free of charge, so a higher cap is not commercially supportable.

Nothing in these terms excludes liability for fraud, gross negligence, death or personal injury caused by negligence, or any liability that cannot be excluded under English law (notably under the Consumer Rights Act 2015).

11. Intellectual property

The Clerkenwell Trains name, logo, layout, code, and the curated content of the site (route landing pages, "today's deals" copy, the cheapest-days calendar) are the property of Jade Browser Limited. You may share links to the site freely; please don't copy substantial blocks of curated content for a competing service.

Train operator names, logos, and timetable data remain the property of their respective owners. We display them under the standard fair-dealing exception for factual rail information.

12. Governing law and disputes

These terms are governed by English law. Any dispute arising from your use of the service will be subject to the exclusive jurisdiction of the Courts of England and Wales, except where mandatory consumer-protection law gives you the right to bring a claim in your country of residence.

13. Changes to these terms

We may update these terms occasionally - typically when we add a new feature, change how we deliver the service, or respond to legal or regulatory updates. When we do, the "last updated" date at the top of this page changes. Material changes will be flagged on the home page for at least 30 days before taking effect.

Your continued use of the service after the change date counts as acceptance of the updated terms. If you don't accept them, please stop using the service.
