Anyone planning a city break, a family holiday or a weekend abroad knows the drill: hunting down attraction tickets, tours and airport transfers across half a dozen tabs before you've even packed a bag. A Klook referral cuts through that faff and rewards you for it — new users who sign up through an invite link and complete their first booking receive a £4 discount to put straight towards that booking.
Klook has become one of the most-used travel activities apps in the world, and its referral programme is a simple, no-catch way to shave a few pounds off your first purchase while you're comparing skip-the-line tickets, day tours and local experiences. This article walks through exactly how the Klook referral works, what you get, how to activate it, and whether Klook itself is worth booking through in the first place.
We'll also cover the platform in proper depth — from its range of activities and pricing structure to its loyalty scheme, support options and how it stacks up against other activity-booking apps — so you can decide if it's the right place to book your next trip.
New customer offer: Sign up to Klook as a new user via a referral invite link and get a £4 discount applied automatically after you sign up, to use on the Klook app.
Referral link: klook.com/en-GB/invite/ZMUYPL
Referral code: ZMUYPL (applied automatically when you use the link)
How to activate: Open the invite link, create a new Klook account (email, Google or Apple), and the £4 discount is credited for use in the Klook app.
Qualifying criteria: You must be a genuinely new Klook user completing your first sign-up through an authorised referral channel. Klook's own referral terms state coupons are earned only through official invite mechanisms and are non-transferable.
Timing: Klook's Terms of Use confirm that referral coupons are issued to your account within 24 hours of your qualifying first booking being completed — so the reward isn't always instant, and in some routes the £4 is applied straight after sign-up, so check your account after registering.

How to Activate Your Klook Referral Discount
- Open the Klook referral invite link on your phone or browser.
- Create a new Klook account using email, Google or Apple sign-in — you must be a first-time Klook user for the offer to apply.
- Check your account or the promo codes section of the app to confirm the £4 discount has landed.
- Browse activities, attraction tickets, tours or transfers for your destination.
- Apply the discount at checkout on your first booking, or use it as instructed if it's issued after your first completed booking.
- Keep the Klook app installed, since some promo codes and reminders are app-exclusive.
If you're doing a Klook referral the other way — inviting a friend — the same rules apply to them: they need to sign up as a new user through your authorised invite link and complete their own qualifying action for either side to see a coupon land.
What Is Klook? A Full Platform Review
Klook is a Hong Kong-founded travel and experiences marketplace that lets you book attraction tickets, guided tours, day trips, airport transfers, travel SIM cards, Wi-Fi devices and more, all from one app or website. It has grown into one of the largest players in the "things to do" booking space, competing directly with GetYourGuide and Viator, and covers thousands of destinations from Tokyo and Bangkok to Dubai and New York.
Products and Services
- Attraction tickets — skip-the-line entry to theme parks, museums, observation decks and landmarks.
- Tours and day trips — guided city tours, food tours and multi-day excursions run by local operators.
- Airport transfers and transport — private transfers, rail passes and shuttle bookings.
- Connectivity — travel SIM cards, eSIMs and pocket Wi-Fi rental for use abroad.
- Experiences — cooking classes, spa treatments, water sports and other activity bookings.
Onboarding and User Experience
Signing up takes seconds via email, Google or Apple, and the app immediately surfaces popular destinations and trending activities. Search and filtering are strong — you can sort by price, rating, or instant confirmation availability — and most listings include real customer reviews, photos and clear inclusions/exclusions before you commit to buying. Booking confirmations and e-tickets are delivered digitally, usually via QR code, which is handy for skip-the-line entry.
Pricing, Fees and Delivery
Klook doesn't charge a separate booking fee on most listings — pricing is generally the ticket or activity price itself, though prices can vary by date, time slot and demand, so it's worth comparing a few days if your plans are flexible. Vouchers and tickets are typically delivered instantly by email and in-app, and many bookings offer free cancellation up to a set cutoff, clearly marked on each listing before purchase.
Rewards, Loyalty and Klook Coupons
Beyond the one-off referral discount, Klook runs "Klook Coupons" as its core promotional currency, earned through the Klook Referral Program when a friend you invite completes their first confirmed booking. According to Klook's Terms of Use, coupons can only be earned through authorised invite channels — not by simply sharing a generic link on unapproved platforms — and Klook reserves the right to adjust reward values or void coupons obtained fraudulently. There's also a regular rotation of app-exclusive flash sales and seasonal discount codes worth checking before booking.
Customer Support
Klook offers in-app live chat and a help centre organised around common issues like booking changes, refunds and promo codes. Response times are generally reasonable for straightforward queries such as rebooking or applying a coupon, though during peak travel periods support volume can slow things down. The app also lets you manage cancellations and refund requests directly, which speeds up resolution for many common problems.
Security and Eligibility
Klook requires a genuine, unique account per referral participant — multiple accounts or attempts to circumvent the referral system are explicitly against its Terms of Use and can result in forfeited coupons. Payment is processed through standard secure checkout with major card and digital wallet support. As with any marketplace, always check listing-specific terms (cancellation windows, minimum notice, age or ID requirements) before booking, since these vary by operator rather than by Klook itself.
Limitations to Be Aware Of
- Referral coupons aren't always instant — the Terms of Use state a 24-hour issuance window after a qualifying booking.
- Quality and communication can vary between local tour operators, since Klook is a marketplace rather than the direct provider of every experience.
- Some high-demand or partner-restricted tickets may not accept promo codes.
- Pricing can fluctuate by date and demand, so it pays to compare before locking in a booking.
Practical Scenarios
- Scenario — first-time city break booker: Someone planning a first solo trip to Tokyo signs up via a Klook referral link, gets the £4 discount, and applies it against a themed café ticket, testing the platform before booking bigger tours later in the trip.
- Scenario — family holiday planner: A family comparing airport transfer options and theme park tickets for a Florida trip uses Klook to bundle several bookings into one app, tracking e-tickets and confirmations in a single place.
- Scenario — last-minute traveller: Someone landing in a new city without pre-booked plans uses the Klook app to find instant-confirmation activities for the same day, relying on user reviews to pick a reliable local operator.
- Scenario — connectivity-conscious traveller: A traveller heading to Southeast Asia orders an eSIM through Klook ahead of departure, avoiding roaming charges from day one.
Comparing Klook's Options
| Booking type | Typical use case | Delivery |
|---|---|---|
| Attraction tickets | Theme parks, museums, landmarks | Instant e-ticket / QR code |
| Guided tours | City tours, food tours, day trips | Confirmation email with meeting point details |
| Airport transfers | Pre-booked pickups to/from airport | Driver details sent before travel |
| SIM/eSIM and Wi-Fi | Staying connected abroad | Physical pickup or instant digital eSIM |
Who Klook Suits Best
Klook is a strong fit for travellers heading to Asia-Pacific destinations, where its ticket and tour inventory is particularly deep, as well as anyone who prefers booking attractions and activities well ahead of a trip rather than queuing on arrival. It also suits budget-conscious travellers who want to stack a referral discount, seasonal promo codes and free-cancellation options across multiple bookings. Less ideal for travellers seeking a single dedicated tour operator relationship, since Klook is fundamentally a marketplace connecting you with many different local providers.
Referral FAQs
How do I claim the Klook referral discount?
Sign up as a new user through the Klook invite link. The £4 discount is credited to your new account for use on the Klook app.
Do I need a promo code as well as the link?
No — using the invite link applies the referral automatically. There's no separate code to type in during sign-up.
How long does it take for the reward to appear?
Klook's Terms of Use confirm that referral coupons for a completed booking are issued within 24 hours; sign-up discounts via an invite link can appear immediately in your account.
Can I use the discount on any booking?
Most bookings qualify, though some high-demand tickets or partner-restricted listings may exclude promo codes — check the terms shown against the specific coupon in your account.
Does the person who invited me also get a reward?
Yes. Klook's referral programme rewards the inviter with a coupon once you complete your first confirmed booking via their authorised invite link.
What happens if I create multiple accounts to claim more coupons?
Klook's Terms of Use explicitly prohibit this, and coupons earned through duplicate accounts or unauthorised channels can be voided.
Is Klook only useful for Asian destinations?
No — while Klook has particularly deep coverage across Asia-Pacific, it also lists attractions, tours and transfers across Europe, the Americas and the Middle East.
What if my referral discount doesn't show up?
Confirm you signed up as a genuinely new user via the invite link, then check the promo codes section of the app. If it's still missing, contact Klook support through the in-app help centre.
Verdict
The Klook referral offer is a straightforward, genuine incentive: sign up as a new user through the invite link and get £4 off, with no complicated hoops to jump through beyond creating your account.
