If you have a Railcard and you travel around London, you can get a third off off-peak pay as you go fares on the Tube, DLR, London Overground, Elizabeth line and National Rail. The catch that stops most people claiming it: the discount only works on a physical Oyster card. It does not work on contactless, Apple Pay or Google Pay. You link the Railcard to the Oyster once, in person, and the cheaper fares apply automatically after that.
This is one of the most overlooked savings in London. People who switched to tapping a bank card years ago often forget the Oyster discount exists. If you commute off-peak, it can pay for the Railcard several times over. Here is how it works and how to set it up.
Can you add any Railcard to an Oyster card?
No, only some. The discount can be set on an Oyster card with these Railcards:
- 16-25 Railcard
- 26-30 Railcard
- Senior Railcard
- Disabled Persons Railcard
- HM Forces Railcard
- Veterans Railcard
If you bought an Annual Gold Card or Gold Record Card with a yearly Travelcard, you can add that to your Oyster for the same discount, no separate Railcard needed. The 16-25 and 26-30 discounts can also go on an 18+ Student Oyster photocard.
These Railcards cannot be added to an Oyster for pay as you go travel: Network Railcard, Two Together, Family & Friends, and the 16-17 Saver. They still get you a discount on Off-Peak Day Travelcards, but not on Oyster pay as you go. The Network Railcard is blocked by a weekday minimum-fare rule that makes it useless inside the Oyster zones, so do not count on it for your daily commute.
How to link your Railcard to your Oyster card
You have to do this in person. There is no way to fully link it online or in the app, which trips a lot of people up. Here are the steps.
1. Register your Oyster card online
Create a TfL account and register your Oyster card in your name. This is not strictly required to add the discount, but it lets you claim refunds or a replacement if the card is lost, and you want that protection once a discount is attached.
2. Take both cards to a station
Bring your Oyster card and your Railcard. The Railcard can be the physical card or the digital version on your phone. Go to a Tube or London Overground station, an Oyster Ticket Stop, or one of the Elizabeth line stations that offer this. Ask a member of staff to add the Railcard discount to your Oyster. In practice it is easiest at a Zone 1 station, where there are usually more staff around the barriers.
3. Staff add the discount to the card
They check your Railcard and flag the discount onto your Oyster card's chip. It takes a minute. That is the whole job.
4. Check that it worked
The only way to confirm the discount is on there is to start a top-up at a physical ticket machine and look for "Discounts: NR Railcard" in the top right of the screen. You cannot check this online, so it is worth doing before you rely on it.
5. Re-add it when your Railcard renews
The discount expires at the same time as your Railcard. When you renew the Railcard, you have to go back and add the discount to your Oyster again. Set a reminder, because nothing prompts you and the cheaper fares simply stop.
The Elizabeth line stations that can add it
Ilford, Romford, Ealing Broadway, West Ealing, Hayes & Harlington, Southall, West Drayton, Abbey Wood, Custom House, Woolwich, Canary Wharf and Paddington. Hours are usually 10:00 to 15:00 on weekdays and 10:00 to 17:00 at weekends, with some closed on Sundays.
Can I link my Railcard to Oyster online?
Not completely. You can register your Oyster online and you can manage top-ups online, but the discount itself has to be added by station staff in person. There is no button on the TfL website or app that links a Railcard to an Oyster. The mayor has said before that he wants to bring the discount to contactless, but as of 2026 it is still Oyster only and still in person. So if a search brought you here hoping to do the whole thing from your sofa, the honest answer is that you will need one trip to a station.
How much does it actually save?
The discount is a third (the exact figure is 33.4%) off two things: off-peak single fares, and the off-peak daily cap. The daily cap part is the one people miss, and it is where the steady savings come from.
Take a single off-peak journey inside Zone 1. The standard fare is £3.00. With the Railcard discount it drops to about £2.00. Now look at the daily cap, which matters more if you make several journeys in a day.
| Zones | Standard off-peak cap | With Railcard | You save |
|---|---|---|---|
| Zones 1-2 | £8.90 | £5.90 | £3.00 |
| Zones 1-3 | £10.50 | £6.95 | £3.55 |
| Zones 1-4 | £12.80 | £8.50 | £4.30 |
| Zones 1-5 | £15.30 | £10.15 | £5.15 |
| Zones 1-6 | £16.30 | £10.85 | £5.45 |
A Zones 1-2 off-peak commuter saves £3 a day. Over a five-day off-peak week that is £15, and a £35 Railcard (the standard one-year price for the 16-25 and several others) pays for itself in about twelve commuting days. After that it is money back in your pocket for the rest of the year. The wider your zones, the more the cap saving grows.
For how the cap works in the first place, including the daily and weekly windows, see our guide to the TfL daily cap.
The limits worth knowing before you bother
The discount only applies off-peak. Peak times are Monday to Friday, 06:30 to 09:30 and 16:00 to 19:00, set by the time you touch in. A journey you start in the morning peak gets no discount at all. If your commute is squarely in the morning rush both ways, the Oyster discount will not help on those trips, though weekend and midday travel still will.
One useful quirk: in the evening peak between 16:00 and 19:00, single fares are charged at peak rates, but the off-peak daily cap still applies. So if you make several journeys across a weekday, the discounted off-peak cap can still catch you even when individual evening fares do not get the discount.
A few more things to keep in mind. The discount does not apply to bus or tram fares, which already have their own low cap, covered in our bus fare cap guide. Journeys to or from Heathrow on the Tube or Elizabeth line that touch Zone 1 are charged peak no matter the time, so no discount there. And once a discount is on an Oyster, you cannot share that card with anyone else, because it is only valid alongside the matching Railcard, which you must carry with you.
Is it worth using Oyster again just for this?
For a regular off-peak traveller, yes, pretty clearly. You give up the convenience of tapping your phone or bank card, and you pay the one-off Oyster card fee (a non-refundable charge of around £7 to £10, so check the current price when you buy). Against that, a third off your off-peak fares and your off-peak cap adds up fast. If you only pass through London occasionally and rarely travel off-peak, the saving may not be worth carrying a separate card. The deciding factor is how often you travel outside the rush hours.
