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 the train operator's own website (Trainline, Avanti West Coast, LNER, etc.) after you click Continue.
We do charge a service fee for the price-discovery and split-ticket work - a flat £1 per booking when our planner surfaces a split, or £1/month for unlimited bookings if you sign in. Direct journeys with no split surfaced are free. The service fee is collected by Stripe Checkout before the hand-off; Stripe is the merchant of record for that £1, issues the receipt, and processes refunds at our instruction.
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. When the cheapest option is on Trainline, we say so; when it's on the operator's own site, we say that.
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

There are two separate payments involved in a typical booking:

Our service fee. A flat £1 per booking when our planner finds a split (or £0 for direct journeys and for active £1/month subscribers). This is collected via Stripe Checkout immediately before we hand you over to the rail retailer. Stripe is the merchant of record; the receipt comes from Stripe. We never see your card details. We can refund the £1 via Stripe on request (e.g. if your Advance fare sells out between fee and booking) and aim to process refund requests within five working days.
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.

If you have problems with our £1 service fee - duplicate charge, fee charged for a journey we didn't help with, subscription cancellation - contact us at jadebrowsercontact@gmail.com or manage your subscription via the Stripe Customer Portal link in your account page.

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. We charge a flat £1 per booking (or £1/month for subscribers); a higher cap is not commercially supportable at this price point.

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.
