The average person in the UK makes 42 impulse purchases a year, spending roughly £943.44 on items they hadn’t planned to buy. That’s nearly a thousand pounds that could have gone into savings, debt repayment, or a holiday. Across the country, those unplanned buys add up to a staggering £64.4 billion annually. Understanding where that money goes and why is the first step to keeping more of it in your pocket.

Impulse spending isn’t about being bad with money. It’s about how modern shopping is designed. Social media feeds, one-click checkout, and aggressive discounts all nudge you toward buying without thinking. The research shows that younger shoppers, particularly those aged 16–34, are far more susceptible to emotionally driven online purchases. But the patterns affect nearly everyone. Here’s what you actually need to know.
Before diving into the numbers, it helps to understand the mechanism behind them. The term for the split-second decision to buy something you hadn’t planned for is impulse purchasing.
What I tend to notice is that most people don’t realise how much these small decisions add up. A £3 snack here, a £20 top there — it feels harmless in the moment. But at £943 a year, it’s the equivalent of a monthly car payment or a decent emergency fund contribution. The research backs that up: one person’s month-long no-spend experiment saved £350 simply by cutting impulse buys and subscriptions.
What the average impulse spend looks like by category
The research breaks down exactly where the money goes. Food and snacks lead, but clothing, takeaways, and beauty products all take a significant slice. The table below shows the percentage of people who regularly impulse-buy in each category, along with the average monthly spend where available.

| Category | % who impulse-buy regularly | Average monthly spend (where available) |
|---|---|---|
| Food and snacks | 51% | — |
| Clothing and fashion | 43% | — |
| Restaurants, cafés, takeaways | 31% | £84 per month on eating out |
| Beauty and skincare | 20% | — |
| 25–34 age group (all categories) | — | £131.03 per month |
The numbers reveal a clear pattern. Food and drink are the most common triggers because they’re low-cost, low-risk, and everywhere — at the checkout, on the delivery app, in the office break room. Clothing is more expensive per item and hits women and younger shoppers hardest. Beauty is growing fast, with the UK beauty sector projected to hit £31.5 billion in 2025, partly driven by miniature products that feel affordable but add up quickly.
What this data doesn’t show is the hidden cost: the items that are bought and never used. In one documented experiment, a week’s impulse buys included a pillow used twice, a soup maker that stayed in its box, and a cork board that never went on the wall. The financial loss isn’t just the purchase price — it’s the space, the guilt, and the time spent managing clutter.
Why social media makes it worse
Social media isn’t just influencing what you buy — it’s changing how fast you buy it. The research found that 56% of Brits say a social media platform influenced an impulse purchase, and 17% say they do it frequently. For 16–24-year-olds, that figure jumps to 35%.
The mechanics are straightforward. TikTok Shop, Instagram shopping tags, and YouTube affiliate links remove the gap between seeing a product and owning it. In-stream shopping on TikTok increased 120% in the past year, and the platform’s active sellers doubled to over 200,000. Social commerce in the UK is projected to nearly double from £7.4 billion in 2024 to £16 billion by 2028.
What I’d do here is treat social media like a shop window you can’t walk past. If you know you’re susceptible — and the data says most people are — the simplest fix is to remove the payment shortcuts. Delete saved card details from shopping apps. Turn off one-click purchasing. Add a 24-hour rule: anything you see on social media, you have to wait a day before buying. The research suggests that most impulse purchases lose their appeal within hours.
Three mistakes that keep the cycle going
Mistaking discounts for savings
Aggressive promotional discounts are the top driver of fast fashion impulse buys, which increased 13% in Q1 2025. A 40% off flash sale feels like a win, but if you weren’t going to buy the item at full price, you haven’t saved 40% — you’ve spent 60% of something you didn’t need. The research shows that discounts specifically trigger impulse purchases in restaurants and takeaways too, with 31% of people ordering food on impulse when a deal appears.
Ignoring the subscription creep
Subscriptions are a quieter form of impulse spending. They don’t feel like a purchase because the money leaves your account automatically. In the no-spend experiment mentioned earlier, cutting subscriptions alongside impulse buys was what made the £350 monthly saving possible. The fix is a quarterly audit: list every subscription, cancel anything you haven’t used in the past month, and ask whether each one genuinely improves your life.
Treating every reward point as free money
Almost half of 16–34-year-olds redeemed restaurant app rewards in the past six months. Loyalty points and app rewards are designed to feel like a bonus, but they often push you toward purchases you wouldn’t otherwise make. A free coffee isn’t free if you buy a pastry to go with it. The research shows that reward redemptions are a significant driver of impulse spending in the food and drink category.
How to break the habit without feeling deprived
The goal isn’t to stop spending entirely — it’s to make sure your money goes where you actually want it to. The research and real-world experiments point to a few practical approaches that work.
The 0.01% rule
One strategy tested in the Guardian’s anti-consumption experiment is the 0.01% rule. Before buying anything non-essential, ask yourself: will this item bring me at least 0.01% of the joy or utility I’d get from my most valued possession? If the answer is no, it’s probably not worth buying. This forces you to compare the potential purchase against something you already know you love, rather than against nothing at all.
Cash stuffing for problem categories
Cash stuffing — withdrawing a set amount of cash for a specific category and spending only that — works particularly well for food and snacks, the top impulse category. If you allocate £50 in cash for weekly snacks and treats, you physically can’t overspend. The research shows that 51% of Brits regularly buy food outside their budget, which suggests that card payments make it too easy to lose track. Cash creates a hard boundary.
The no-spend challenge
A structured no-spend period — a week or a month where you buy only essentials — resets your relationship with spending. The documented experiment found it was easier than expected (rated 6/10 difficulty) and saved £350 in a single month. The key is defining “essentials” clearly beforehand: rent, bills, food, transport, and nothing else. After the challenge, most people find they naturally spend less because they’ve broken the automatic habit.
Gratitude journaling as a spending brake
It sounds soft, but the research supports it. Gratitude journaling — writing down three things you’re grateful for each day — reduces the emotional void that impulse purchases often fill. When you’re content with what you have, the urge to buy something new loses its edge. One of the tested strategies in the Guardian experiment found that regular gratitude practice directly reduced the frequency of unplanned purchases.
What to do when you feel the urge to buy
The moment between wanting something and buying it is where the battle is won or lost. Here’s a step-by-step process based on what actually works.
- 1Pause for 24 hoursAdd the item to a wishlist or basket, then close the tab. Set a reminder for the next day. Most impulse urges fade within hours.
- 2Ask three questionsDo I need it? Will I use it? Is it worth it? Martin Lewis’s three-question framework is simple but effective. If the answer to any is no, don’t buy.
- 3Calculate the real costDivide the price by your hourly after-tax wage. A £40 top costs about two hours of work. Is it worth two hours of your life?
- 4Remove the frictionDelete saved payment details from shopping apps and social media platforms. If you have to get up and find your wallet, you’re less likely to buy.
If you find yourself consistently struggling with a specific category — say, beauty products or fast fashion — it’s worth asking whether a deeper pattern is at play. The research shows that younger shoppers are particularly susceptible to emotionally or socially driven purchases. If you’re buying to feel a certain way or to fit in, no budgeting technique will fix the root cause. That’s where talking to a professional can help. Services like a financial advisor can help you untangle the emotional from the practical.
