In this guide
Two-for-one entry to the Tower of London, Kew Gardens and Westminster Abbey has been running quietly for years, and it is genuinely one of the better deals in the city. It is also the single most misreported thing about visiting London.
Almost every guide to it online is out of date in the same three ways. This one is not, and the corrections are the reason to read it.
⚠️ Oyster and contactless do not qualify. Not the card, not the phone, not a Travelcard bought at a Tube station. The offer needs a National Rail ticket, and the widely repeated advice to “print your TfL journey history instead” describes a process that does not exist.
💡 The Short Version: You need two people, two valid National Rail tickets, an eVoucher, and an attraction that is actually in the scheme. Get any one of those wrong and you pay full price at the door.
What the scheme actually is
It is run by ATOC/RDG on behalf of Britain’s train companies, under the name Days Out Guide. The logic is simple: the railway wants you to travel by train, so it buys you a discount at the other end.
The five steps are:
- Choose your attraction
- Download your eVoucher, or book online where the attraction requires it
- Travel by train
- Show the eVoucher and your train tickets at the attraction
- Go in
There are three redemption routes, and which one applies is set per attraction — the listing page carries a badge saying which.
| Route | What you do | Examples |
|---|---|---|
| Pay at the door | Show the eVoucher on your phone; sometimes a QR code is scanned | Tower of London, Kew, Westminster Abbey |
| Advance booking required | Book on the attraction’s own site using a named ticket type, then show train tickets on arrival | Tower Bridge, St Paul’s, The Shard |
| Paper voucher | Legacy only — creation closed March 2026, redeemable to end of December 2026 | Being phased out |
Which train tickets count
This is the part that decides whether you get in, so it is worth being precise.
These work:
- Anytime, Off-Peak and Advance tickets
- Travelcards bought at a National Rail station
- E-tickets showing the National Rail double arrow
- Season tickets — 7-day, monthly or longer
- Gatwick Express, Stansted Express, SailRail, Caledonian Sleeper
- Smartcards such as The Key and c2c smart
- Railcard and GroupSave discounted tickets — the discount does not disqualify you
These do not:
- Oyster cards, including concessionary ones — except a Gold Record card for an Annual Season
- Contactless bank cards and payment apps used to tap in
- Travelcards sold at Underground or DLR stations
- Tube, DLR or bus-only tickets
- Freedom Pass
- Heathrow Express, Eurostar, Eurail and Interrail
- E-tickets without the National Rail logo
💡 The rule of thumb Days Out Guide gives itself: the best indication of a valid ticket is the National Rail double arrow symbol. If your ticket has it, you are fine.
Paper versus digital is not the distinction. A National Rail e-ticket on your phone is perfectly valid. The line that matters is National Rail ticket versus TfL tap — and a tap leaves you with nothing to show.
Your destination has to make sense. Tickets need to show you travelled to the attraction by train; a ticket reading “London Terminals” works for London offers. Staff can refuse a ticket whose destination is nowhere near the attraction.
Keep hold of the ticket. Ask staff to let you through the barrier manually so the gate does not swallow it — you need it at the other end.
Validity, and how long a ticket stretches
- A single, or a return valid one day, covers offers on the day of travel
- A return covers any day between your outward and return dates — travel down Thursday, back Sunday, and all four days work
- The date you downloaded the voucher does not have to match your visit
- A voucher can be used on its expiry date
- One train ticket covers multiple attractions on any day that ticket is valid
- One voucher per two people, up to three vouchers per attraction — so six people maximum
That third point is the one people miss. A weekend return from Brighton or Cambridge unlocks two-for-one on Friday, Saturday and Sunday, at as many participating attractions as you can reach.
Which London attractions are in it
There are over a hundred London offers. These are the big draws, each verified on its own listing page.
| Attraction | Route | Notes |
|---|---|---|
| Tower of London | Pay at the door | Standard daytime admission only. Excludes 19–31 December |
| Kew Gardens | Pay at the door | Not combinable with any other discount |
| Westminster Abbey | Pay at the door | Cannot be pre-booked. Adds a free child per adult ticket |
| Hampton Court Palace | Pay at the door | Excludes late August and 28 Nov–31 Dec |
| Kensington Palace | Pay at the door | Heavy blackouts — Easter, 18 July–31 August, and Christmas |
| ZSL London Zoo | Advance booking | Excludes Christmas Day |
| St Paul’s Cathedral | Advance booking | Mon–Sat only; must select the National Rail ticket type |
| Tower Bridge | Advance booking | Named ticket type plus promo code at checkout |
| The View from The Shard | Advance booking | Book 24 hours ahead; general entry only |
| London Transport Museum | Pay at the door | Offer is on annual passes, not day tickets |
Also included: Cutty Sark, the Royal Observatory, the Painted Hall at the Old Royal Naval College, Shakespeare’s Globe tours, the Royal Albert Hall tour, the Charles Dickens Museum, Chelsea Physic Garden, the Household Cavalry Museum, Eltham Palace, Apsley House, the Chelsea, Arsenal, Spurs and Wembley stadium tours, and river trips with City Cruises and Thames Rockets.
Major exhibitions are included too, which is the underused part — Tate Modern and Tate Britain’s paid shows have carried 2FOR1. These rotate constantly, so check the listing rather than trusting any article, including this one.
⚠️ These are NOT 2FOR1. The London Eye is one third off, not two-for-one — and so are Madame Tussauds, SEA LIFE London Aquarium, the London Dungeon and Shrek’s Adventure. All five are Merlin attractions with their own separate terms. Plenty of guides still list the London Eye as 2FOR1. It is not.
⚠️ Not in the scheme at all: the Churchill War Rooms, HMS Belfast, Buckingham Palace and the Royal Mews, the V&A, the Royal Academy, Sky Garden and the Postal Museum. The War Rooms in particular is claimed by a lot of blog posts. It has never been there.
Is it actually worth it?
Often yes, sometimes no, and the difference is worth understanding before you build a day around it.
The offer is calculated on walk-up pricing. Days Out Guide says so directly: offers apply to “on the door” prices, which are frequently higher than the advance rate on the attraction’s own website. Two advance tickets bought online can beat 2FOR1 on the gate price. Check both before you commit.
It is full-price adult tickets only. Buy an adult and a child ticket together and the cheaper one is deducted — so a family gets far less out of it than two adults do.
It never combines. Not with family tickets, group rates, other vouchers or concessions. A family ticket often wins outright.
The blackout dates land on exactly the days visitors come. Kensington Palace excludes the whole of the Easter holidays, all of 18 July to 31 August and Christmas. Hampton Court excludes late August and all of December.
A solo traveller gets nothing. There is no single-visitor version.
Advance-booking offers are fiddly. St Paul’s and Tower Bridge both need a specific, easy-to-miss ticket type selected at checkout. Pick the wrong one and the discount is gone with no way back.
Capacity is not guaranteed. At the Historic Royal Palaces sites, if your slot is full when you arrive you wait for the next one. Westminster Abbey cannot be pre-booked at all.
💡 The honest verdict. 2FOR1 is excellent for two adults arriving by train from outside London who were buying rail tickets anyway. It is usually pointless for someone already in London on contactless — buying a throwaway rail ticket to unlock it normally costs more than it saves.
How this squares with our fares advice
Our transport costs guide tells you to use contactless or Oyster and avoid paper tickets. For getting around London, that advice is right and we stand by it.
2FOR1 is the one case where it works against you. If you are coming in from outside London and plan to visit paid attractions, the National Rail ticket you were buying anyway unlocks a discount that contactless cannot. That is not a reason to change how you pay for the Tube — it is a reason to keep the rail ticket you already have rather than binning it at the barrier.
Practical notes
Station leaflets still exist, but only at stations served by c2c, Stansted Express, Greater Anglia, LNER, GWR and Chiltern, and only while stocks last.
Rail staff holding a Leisure Card or Priv Card need no train ticket at all — the card covers them plus one.
Attractions can refuse photocopied, damaged or defaced vouchers, and can refuse entry where the conditions have not been met, with no refund.
Anyone can use it — residents and overseas visitors alike. The only requirement is that you travelled by National Rail.
Offers, prices and rules checked on 1 September 2026. This scheme changes constantly and attractions rotate in and out — always confirm on the attraction’s own Days Out Guide listing before you travel.

Common questions
Can I use Oyster or contactless for 2FOR1?
No. Days Out Guide lists Oyster cards, contactless bank cards and payment apps, Freedom Passes, and Travelcards bought at Underground or DLR stations as invalid. The one exception is a Gold Record card for an Annual Season ticket held on Oyster. There is no way to print a TfL journey history as a substitute — that route does not exist, despite being widely repeated online.
Do I need to print the voucher?
Not any more. Paper voucher creation closed at the end of March 2026 and was replaced by eVouchers shown on a phone, though paper vouchers already downloaded stay redeemable to the end of December 2026. Days Out Guide's own FAQ page still says printed vouchers are required, which contradicts its terms and conditions — the live attraction pages follow the terms.
Is the London Eye 2FOR1?
No. The London Eye is one third off, not two-for-one, and it requires advance booking. The same applies to Madame Tussauds, SEA LIFE London Aquarium, the London Dungeon and Shrek's Adventure — all Merlin attractions, all a third off rather than 2FOR1.
Is 2FOR1 worth it if I already live in London?
Usually not. The offer needs a valid National Rail ticket, and buying one purely to unlock the discount normally costs more than it saves. The scheme rewards people already arriving by train from outside London.
Does a single traveller get anything?
No. 2FOR1 means two people paying for one full-price adult ticket. There is no single-visitor equivalent, and if you buy an adult and a child ticket together the cheaper of the two is what gets deducted.
