How the Tower of London 2-for-1 Offer Works
The 2-for-1 admission offer for the Tower of London is part of the Days Out Guide scheme, run in partnership with National Rail. It operates on a simple principle: if you travel to London by National Rail train, you can claim one free adult admission when a second adult pays full price.
This is a legitimate, well-established scheme that has been running for years. It's not a scam, not a trick, and not a limited-time promotion โ it's an ongoing offer available year-round.
- Travel to London on any National Rail service
- Download and print (or save digitally) the voucher from daysoutguide.co.uk
- Present the voucher + your train ticket at the Tower box office on the day
- One adult gets in free when another pays full price (from ยฃ34.80)
Step-by-Step: How to Claim 2 for 1
Step 1: Buy a National Rail ticket to London
Any National Rail train ticket to a London terminal station qualifies. This includes tickets to: London Victoria, Waterloo, Paddington, Liverpool Street, King's Cross, St Pancras, Charing Cross, Cannon Street, Fenchurch Street and others. The ticket must be for a National Rail service โ Eurostar, Overground, TfL Rail and the Elizabeth Line do NOT qualify (even though they serve London).
The cheapest qualifying ticket works just as well as the most expensive. An advance off-peak single to London Bridge for ยฃ15 gives you the same 2-for-1 benefit as a standard open return for ยฃ80.
Step 2: Download the voucher
Visit daysoutguide.co.uk and search for the Tower of London. Download and save the 2-for-1 voucher โ as a PDF or screenshot on your phone. You must have the voucher with you; you cannot claim the offer without it.
Step 3: Present at the box office on the day
Go to the Tower of London ticket office (main gate area, west side) with both:
- Your National Rail ticket (physical or digital) โ for the same day of travel or with a valid date range that includes today
- The Days Out Guide voucher (printed or on your phone screen)
Present both to the ticket desk. Pay for one adult admission; the second adult enters free.

Who Does and Doesn't Qualify
Qualifying scenarios
- Two adults travelling to London from anywhere in the UK on National Rail
- One adult with a season ticket that includes a National Rail London terminal
- Groups where at least two adults each have valid National Rail London tickets
Non-qualifying scenarios
- London residents travelling on Tube, bus or Overground only
- Visitors arriving by Eurostar from Europe (Eurostar is not National Rail)
- Day trip visitors on a coach or car who haven't used a National Rail service
- Those with Elizabeth line tickets only (even to Paddington or Liverpool Street)
The 2-for-1 offer requires redemption at the box office queue. On busy days, this queue can be 30โ60 minutes. If saving money is your priority and time is flexible, this is fine. If you're visiting in peak season and want to avoid queuing, the standard pre-booked online ticket (at a small premium over the 2-for-1 deal) gets you a faster entry lane and secured time slot.
2-for-1 vs Online Booking โ Which Saves More?
Let's do the maths for two adults:
| Option | Cost for 2 adults | Notes |
|---|---|---|
| Standard online booking (ร2) | ~ยฃ65โ70 | Online prices typically below gate rate |
| 2-for-1 at gate (ร1 full price) | ~ยฃ34.80 | One adult free, one pays gate rate |
| Saving with 2-for-1 | ~ยฃ30โ35 | Plus any train ticket cost to consider |
The 2-for-1 saves significantly โ but only makes sense if you were going to use National Rail to travel to London anyway. If you're already in London and using the Tube, there's no saving to be had (you'd have to buy a separate train ticket to qualify, which isn't worth it for the discount alone).
Is There a 2-for-1 for Tower Bridge Too?
Yes. The Days Out Guide National Rail 2-for-1 scheme also covers Tower Bridge (separately). If you want to visit both attractions with 2-for-1 on both, you'd need two valid Days Out Guide vouchers (one for each attraction) and two qualifying train tickets โ one per attraction per day. Alternatively, consider the Tower of London + Tower Bridge combo ticket, which may offer better overall value.
Tower of London 2-for-1 for National Rail Cardholders
The offer is available to all National Rail ticket holders, including those with:
railcards (16โ25, Senior, Two Together, Family, Network), season ticket holders, and anyone with any valid point-to-point National Rail ticket to a London terminal.
