PlanTripLondon’s Promo Codes for London Attractions

Promo Code for Minicabit
For private airport transfers from London’s airports to central London, we recommend booking a Minicab. This way, you can book in advance and pay a fixed price, not having to depend on a taximeter, so even if there is traffic, you will not pay more than the agreed amount. You can also compare different minicab companies easily and choose the one you like most using a comparison website such as Minicabit. You can get a £5 discount using our promo code QVERLONDRES5.

Temporary Promo Codes for London Attractions
Very occasionally, London Attractions have temporary promo codes available, but if you´re fortunate, you may be able to find one here. We add them when they become available.
Promo Codes for City Cruises
Sightseeing Passes available for London Attractions
Buying a tourist pass is one of the best ways to make the most of your money when visiting London. A few options are available, although the London Pass is one of London’s most famous sightseeing passes. You can purchase a pass for a single day or multiple days and visit as many attractions as possible during the days your pass is valid. The trick here is to plan your days very well to make the best of the pass, but we have done all the legwork for you and designed some itineraries to help you make the most of your London Pass here: London Pass Itineraries.
Before paying on the London Pass website, you can try QVERLONDRES5 and check whether it reduces your total. Do not budget on a fixed percentage until the checkout confirms it.
Other sightseeing passes are the Go City Explorer Pass and Merlin Group Pass.
Choosing a sightseeing pass depends on how many days you wish to use your pass for and what attractions you want to visit, so check out our guide Tourist Passes in London, for more information.
Combo tickets and attraction packages
Another way to get into London Attractions cheaper is by buying combination tickets; this way, you choose from one of the deals that include several attractions and save quite a significant amount per person.
You can find the best combo tickets on Discount London and GetYourGuide, but check out our article on Combination tickets to visit London Attractions for all the information you need.
2FOR1 national rail offers
If you plan to travel to London by train, you could use the 2FOR1 National Rail offers through daysoutguide. This needs some planning, though, as you need to ensure your train tickets qualify for these offers.
Generally speaking, National Rail tickets purchased from a train operating company or retailer, including advance, anytime, off-peak, Gatwick Express, Stansted Express and Travelcards (but only when purchased from a National Rail station). Other tickets that are valid for this offer are: eTickets (as long as they show the National Rail logo), season tickets (7-Day, Monthly or longer), Gold Record Card (when shown as evidence of a Season ticket held on a smartcard), National Rail train company issued smartcards (shown as evidence of a ticket held on smartcard e.g. The Key, c2c smart), BritRail passes (if the attraction has specified that they will accept these tickets) and Rail Staff Leisure Card.
If you are making a one-way journey or your return ticket is valid for one day, you can use your National Rail tickets to qualify for 2FOR1 offers on the day of travel. If you are making a return journey, you can use your National Rail ticket to qualify for 2FOR1 offers on any day on or between your outward and return dates.

Some exclusion dates apply across selected attractions – check full T&Cs on their website for details.
Kellogg’s 25% off Merlin attractions (2026–27)
The current Kellogg’s x Merlin offer gives 25% off up to two eligible adult or child online-priced standard single-day tickets for visits from 1 June 2026 to 30 June 2027. Participating London attractions include the London Eye, SEA LIFE London, Madame Tussauds London, the London Dungeon and Shrek’s Adventure! London. This is a discount on online ticket prices, not a free adult ticket.
How to claim the 2026 offer:
- Buy a Kellogg’s promotional pack marked with the 25% offer. Scan its QR code or go to Kellogg’s promotion site, sign in or register, and enter the 10-digit pack code beginning with K.
- Wait for the unique discount code to arrive by email; Kellogg’s says this can take up to 24 hours.
- Choose a participating attraction on Merlin’s Kellogg’s booking page, enter the discount code during checkout and book no later than 11pm on the day before your visit.
Each promotional pack allows one redemption covering up to two eligible tickets. Booking is subject to ticket availability; the discount cannot be combined with other offers and excludes combination tickets, accommodation and parking. Check the official 2026 promotion terms and the attraction’s opening dates before buying a pack or booking.
The photographs below show earlier 2-for-1 packaging, not the current 25% offer. Use a participating pack labelled with the current promotion.
Cadbury discounts at Merlin attractions: 2026–27
The old free-ticket offers described in earlier versions of this guide expired in 2023. The 2026 Cadbury “Who Will You Take?” promotion instead offers 10%–50% off up to four adult or child online advance-priced tickets at participating Merlin UK attractions, for visits from 1 April 2026 to 30 June 2027. The saving depends on the attraction and visit date; 50% is not available on every day.
- Use a participating 2026 promotional pack and keep its barcode and batch code.
- Enter the pack details on the official Cadbury promotion website to receive your booking code and link.
- Book online by 11 pm the night before your visit. Promotional ticket allocations are limited.
- The promotion is for UK residents aged 18 or over. One claim covers up to four tickets per pack, and it cannot be combined with another promotion.
Compare the promotional total with the attraction’s ordinary online price before paying. An old pack or screenshot of a previous offer is not proof of eligibility for this season.
Blue Peter Badge
If your child is between 5 and 15 years old, they can apply for a Blue Peter badge, which will give them free entry to over 200 attractions in the UK as a Blue Peter badge holder.

Gardeners’ World 2-for-1 Gardens: 2026–27
The current BBC Gardeners’ World scheme covers more than 360 gardens in the UK and Ireland until 24 March 2027. The card gives two adults entry for the price of one full-paying adult, subject to each garden’s conditions. This replaces the old May 2023 offer previously listed here.
You can buy a digital card through the 2-for-1 Gardens app for £9.99, or obtain the printed card and guide with the May 2026 magazine package. Check the current participating-garden list and booking rules before choosing a day out; do not assume a garden listed in an older edition still participates. Show the original card or the live digital card in the app, not a screenshot.
