McDonald's UK launched MyMcDonald's Rewards in 2021 with a clear ambition: give frequent customers a reason to choose McDonald's over a Pret, a Greggs, or a chicken shop when the options are broadly comparable. Earn points on every purchase, redeem them for free menu items, and build a direct digital relationship with the people who are already eating there twice a week.
It worked. Millions of UK customers enrolled, and the programme quickly became one of the most-used food loyalty schemes in the country. The McDonald's app became a habitual part of how regulars interacted with the brand: check the app, apply points, collect more points, repeat. The habit loop was tight and reinforcing.
Then, in 2024, McDonald's UK restructured the earn rates and redemption table. Some rewards now required more accumulated points than before. For customers who had been methodically building toward a specific reward, the goalposts had moved. The communication was not absent, but it was limited. And the reaction from loyal customers was swift, vocal, and disproportionate to the scale of the financial change involved.
This article is not primarily about McDonald's. It is about what the episode reveals about the implicit contract between a business and its loyalty programme members, and what every small business should understand before designing a programme of their own.
What happened: the MyMcDonald's Rewards restructuring
When MyMcDonald's Rewards launched, the earn-and-redeem mechanic was designed to be visible and accessible. A typical order generated points that moved the customer meaningfully toward a reward within a few visits. The early reward thresholds were achievable without requiring an unusual level of commitment to the programme.
The 2024 restructuring changed the relationship between points earned and points required to redeem. Some items in the rewards menu became more expensive in point terms. A customer who had 2,000 points and was expecting to redeem them for a specific item found that the same item now required 2,500 points, or that the item had been replaced by a less desirable alternative at the same point cost.
McDonald's communicated the changes, but the notice period was short. Customers who were actively building toward a specific reward had limited time to adjust their behaviour before the new table took effect. In loyalty programme terms, this is the most damaging version of a devaluation: not a structural change to an abstract earn rate, but a visible, immediate reduction in the value of points a customer already held.
The social media response in the UK was significant. Reddit threads in UK-focused communities accumulated hundreds of comments. Review platforms saw a spike in negative mentions referencing the points change. Twitter and X saw coordinated criticism from users who had been loyal programme participants since launch. The language used was consistent: "betrayal," "not worth it anymore," "they changed the rules."
That language is worth paying attention to. Customers did not describe the change as a business decision or a margin adjustment. They described it as a breach of trust.
Why it matters: the implicit contract of a loyalty programme
A loyalty programme is not simply a discounting mechanism. It is a promise. When a business says "earn points on every purchase and redeem them for rewards," it is making a commitment to a specific value exchange. The customer's side of the exchange is to buy repeatedly, often from habit or deliberate choice, in anticipation of a future reward. The business's side is to honour the terms of that reward when the customer has earned it.
Customers who accumulate loyalty points are not passive participants. They are making active decisions to buy from you rather than a competitor, sometimes at a slight inconvenience or cost to themselves, specifically because of the programme. They are your most loyal customers by definition. They have self-selected into the group that values the long-term relationship most highly.
Devaluation breaks the contract with exactly those customers. A casual participant who barely uses the programme will barely notice a change in earn rates. A committed member who checks their balance regularly and is 500 points from a reward they have been working toward for two months will notice immediately, feel the loss acutely, and be more likely to quit the programme entirely than a lapsed member who was barely engaged.
The research on this pattern is consistent across the loyalty industry. NPS drops of 15-25 points have been documented in the months following a public loyalty devaluation event, and the drop is concentrated among the highest-frequency programme users, exactly the customers whose NPS you most want to protect. You are not just losing a marginal participant. You are losing the people who were your strongest advocates.
Why small businesses are more exposed, not less
You might assume that a McDonald's-scale devaluation is a problem for large programmes with millions of members, and that a small loyalty programme at a coffee shop or hair salon is too modest to attract this kind of scrutiny. The opposite is true.
A McDonald's customer who quits MyMcDonald's Rewards still buys Big Macs. The loyalty programme is a retention layer on top of a brand habit that is deeply embedded from childhood. The customer might feel betrayed, but they are not going to stop eating there. The brand loyalty and the programme loyalty are separate.
For an independent coffee shop or salon, they are not separate. The programme is the relationship. The loyalty card is, for many regular clients, the primary channel through which they feel remembered and valued by the business. If you change the terms of that programme in a way that feels unfair, the customer does not just quit the programme. They rethink whether to keep coming back at all.
The financial consequences are also steeper relative to scale. A McDonald's NPS drop costs the company a fraction of a percentage point in same-store sales. For a cafe with 200 loyalty members, losing 30 of your most committed regulars to a competitor because of a perceived programme betrayal can be the difference between a profitable quarter and a loss.
What to do instead: designing a programme you can sustain
The McDonald's episode contains a clear practical lesson: design your reward structure to be permanently sustainable before you launch, not adjustable-later-if-margins-are-squeezed.
This requires a different kind of thinking at the design stage. Most businesses launching a loyalty programme think about what will attract sign-ups and drive early engagement. Fewer think carefully about whether the reward economics are sustainable at high redemption rates, at different seasonal revenue levels, or if their cost base increases.
The questions worth answering before launch are straightforward. If 50% of your active members redeem their reward every cycle (which is a reasonable planning assumption for a digital programme), what does that cost you in margin per month? If your food costs increase 10% in the next 12 months, can you still honour the same reward at the same earning threshold? If not, what would you do, and what would you tell your members?
A business that has worked through those questions before launch is much less likely to find itself in a position where a mid-programme change is necessary. And if a change is genuinely required, having thought through the communication and the fairness principles in advance makes handling it better.
If you must change your programme: a better approach
There are situations where a loyalty programme change is genuinely necessary. Food costs rise, margins shift, the original reward design turns out to be more costly than anticipated. In those situations, the worst outcome is a change that feels sudden, opaque, and disproportionately punishing to your most committed members.
A better approach has three components. First, give 90 days' notice minimum. Announce the change before it takes effect, explain why it is happening (customers respond better to honesty than to corporate language about "programme enhancements"), and give members enough time to use their existing balance under the old terms if they choose to.
Second, grandfather existing members at the old rate for a transition period. If your stamp count is moving from 8 to 10, members who currently hold 5 stamps should complete their current card under the 8-stamp rules before the new rules apply. This respects the progress they have already made and makes the change feel earned rather than stolen.
Third, add something rather than just subtracting. If you are reducing the value of the reward, consider adding a new benefit at the same time, even a small one. A change that reads "we're increasing the stamp count from 8 to 10, and we're adding a members-only 10% off every Monday" is significantly less damaging than a straight reduction, even if the Monday discount is not particularly costly to you.
None of these approaches eliminates the trust cost of changing a loyalty programme. But they reduce it to a level that most committed members can accept, rather than one that drives them to a competitor.
What small businesses can learn from the structural design
The McDonald's case also highlights a structural advantage that simple loyalty mechanics have over complex points programmes. Points programmes are, almost by design, partially opaque. The relationship between spending and reward value is abstracted through a points currency that most customers do not track precisely. That opacity is part of the design: customers feel they are earning constantly without calculating the exact value of each transaction.
But opacity cuts both ways. When a points devaluation happens, customers who had not been tracking carefully suddenly discover the change, often at the moment they try to redeem. The discovery feels worse than a transparent change would have, because it combines the bad news of reduced value with the added frustration of not having been told directly.
A stamp card mechanic ("buy 8, get 1 free") is almost immune to this dynamic. There is no opacity. There is a number on the card, and it counts down. Changing the number from 8 to 10 is immediately visible to every cardholder. The change cannot be made quietly. That visibility is a constraint on the business, but it is also a protection: if you set the stamp count at a sustainable number at launch, you are much less likely to need to change it.
The discipline of designing a reward that is honest and sustainable at launch is the most important structural choice in a loyalty programme. It is significantly easier to maintain customer trust with a modest, reliable reward than to launch an ambitious programme and then walk it back.
The real cost of a devaluation is the trust you cannot buy back
There is a well-established asymmetry in customer relationships: trust is built slowly and lost quickly. A loyalty programme member who has been with you for two years and visited consistently is not just a revenue figure. They are a recommendation engine. They are the person who tells their colleagues where to have lunch, who mentions your salon when a friend asks for a recommendation, who leaves the five-star review without being asked.
Losing one of those customers to a perceived programme betrayal does not just cost you their future revenue. It costs you the referrals they would have made over the next two years, the positive reviews they would have left, and the word-of-mouth that cannot be replaced by advertising spend.
The NPS research puts numbers on this. Customers enrolled in a loyalty programme score an average of 22 points higher on NPS than non-members. Customers who have experienced a loyalty devaluation they perceived as unfair score lower than customers who never joined the programme at all, often by 10-15 points. The programme that was generating advocacy is now generating detraction.
For a small business, the practical implication is simple. The safest loyalty programme is the one you design to last, with a reward structure you can honour without revision, and a communication relationship with members that is honest enough that they would not be surprised by any changes you need to make. The most expensive loyalty programme is the one you launch to impress and then have to walk back.
McDonald's can absorb the NPS drop from a points restructuring. Most independent businesses cannot.
