How to earn cashback on London Tube travel (TFL)

Table of Contents

Paying for Transport for London (TfL) isn’t exactly cheap—but there are a few smart ways to claw some of that money back. If you’re commuting regularly, even small % gains can add up to £50–£150+ per year.

1. Use a cashback debit card (easy win)

• Cards like Chase UK offer ~1% cashback

• Works on:

  • Contactless tap in/out

  • Travelcards

£130/month commute = ~£15/year back for doing nothing differently

2. Stack cashback for even bigger savings

Real example (3% cashback setup)

A solid real-world way people are doing this:

• Use Zilch → ~2% cashback

• Stack with PayPal debit → ~1% extra
  Total = ~3% back on travel spend

How to make it work with TfL

The key trick is how you pay:

Instead of tapping directly,
Top up an Oyster card using Zilch

Why this works better:

• You activate Zilch once when topping up (not every journey)

• Avoids timing issues with TfL charging later (which can break cashback)

• More reliable tracking vs contactless taps

Bonus:

• Easier to track your spend vs waiting for contactless charges to settle

Common mistake

If you try to use Zilch directly on tap-in/tap-out:

• TfL often charges later (sometimes overnight)

• Cashback may drop to a lower rate or not track properly

That’s why Oyster top-up > direct contactless for stacking

3. Railcard discount (biggest saver)

If you’re eligible, this is where the real savings are:

• Add a 16-25 Railcard or 26-30 Railcard to your Oyster card

• Get 1/3 off off-peak fares

Can easily save £200–£300+ per year

4. Understand daily caps (this is where most savings come from)

TfL automatically caps your daily spend—once you hit the cap, all further journeys that day are free.

2026 Tube daily caps (pay-as-you-go)

• Zones 1–2 → £8.90

• Zones 1–3 → £10.50

• Zones 1–4 → £12.80

• Zones 1–5 → £15.30

• Zones 1–6 → £16.30

Example:

• If you make multiple journeys in a day, you’ll hit the cap quickly

• Every extra journey after that = £0

Zone 2–3 commuters will often sit around the Zones 1–3 cap equivalent depending on route

Bonus: Bus & tram cap (cheap alternative)

• Bus & tram cap = £5.25/day

• Unlimited travel once hit

If you can swap Tube for buses → big savings

Important cap tips

• Cap runs 04:30 → 04:29 next day

• Travelling through more zones = higher cap

• Some services (e.g. airport routes) don’t always count

• Contactless and Oyster both support capping

Best setup (simple + effective)

1. Use a cashback debit card (baseline 1%)

2. Stack cashback methods (link above)

3. Add a Railcard if eligible

4. Structure travel to hit daily caps efficiently
