The best money-saving apps in the UK in 2026 are TopCashback (cashback on 5,000+ retailers), Too Good To Go (surplus food at 30–60% off), and Shopmium (in-store grocery cashback) — active users save £30–£150/month. Apps cannot save money for you automatically — you have to use them. But the best money-saving apps reduce the friction of finding deals, cashback, and savings to a few seconds per transaction. Here are the ones worth using in 2026.
Cashback Apps
| App | What it does | Typical saving |
|---|---|---|
| TopCashback | Cashback on 5,000+ UK retailers | £100–£500+/year for active users |
| Quidco | Cashback on 4,000+ retailers; free and premium tiers | £80–£400/year |
| Shopmium | Cashback on specific branded grocery products (scan in-store) | £5–£20/month |
| Checkoutsmart | Similar to Shopmium; grocery product cashback | £5–£20/month |
| Greenredeem / Huyu | Smaller grocery cashback platforms | Variable |
How to use Shopmium and Checkoutsmart: Browse offers before your shop, add to shopping list, scan the product barcode in-store, photograph receipt, cashback credited.
Food Saving Apps
| App | What it does | Typical saving |
|---|---|---|
| Too Good To Go | Buy surplus food from local restaurants, supermarkets, cafes at 30–60% off | £10–£40/month |
| OLIO | Free food from neighbours and local shops | Variable |
| Karma | Similar to Too Good To Go | Variable |
| Trolley | UK grocery price comparison | Helps find cheapest supermarket |
| MySupermarket | Price comparison across UK supermarkets | Research only |
Too Good To Go works best in cities where high-density restaurants and bakeries list surplus food daily. In rural areas, listings are sparser.
Bill and Subscription Management Apps
| App | What it does |
|---|---|
| Snoop | Connects to your bank; spots bills, flags increases, suggests savings |
| Uswitch | Comparison site app for energy, broadband, insurance |
| Moneyfacts | Financial product comparison |
| Bank apps (Monzo, Starling) | Built-in subscription tracking and spending categorisation |
Snoop is particularly useful for households who haven’t audited their bills — it reads your bank transactions and highlights bills that have increased, suggests cheaper alternatives, and identifies unused subscriptions.
Price Tracking Apps and Extensions
| Tool | What it does | Best for |
|---|---|---|
| CamelCamelCamel | Amazon price history tracker | Buying electronics/products on Amazon |
| PriceSpy | Price comparison and history across UK retailers | Electronics, appliances, cameras |
| Honey (browser extension) | Auto-applies discount codes at checkout; shows price history | Online shopping |
| Google Shopping | Price comparison at search | Quick multi-retailer comparison |
CamelCamelCamel is valuable for Amazon purchases — it shows the price history of any item. “Amazon Warehouse Deal” and Prime Day prices should be compared against the historical low, not just the “original” price Amazon shows.
Discount Code Apps
| App | What it does |
|---|---|
| Honey / PayPal Honey | Auto-applies codes at checkout |
| Pouch | UK-focused coupon extension |
| VoucherCodes | Browse current voucher codes by retailer |
| MyVoucherCodes | Similar; good for restaurant and retail codes |
Recommended Starter Stack (3 Apps)
If you are starting from zero, begin with:
- TopCashback — cashback on major purchases (insurance, broadband, online shopping)
- Too Good To Go — food savings near you
- Your bank’s own app — subscription tracking and spending overview
Add Shopmium/Checkoutsmart once you’re comfortable with the first three.

How Much Can You Realistically Save? — By Commitment Level
Money-saving apps require active use. Here is what different levels of engagement produce:
| Commitment level | Apps used | Realistic monthly saving |
|---|---|---|
| Minimal (check occasionally) | TopCashback on major purchases only | £5–£15/month |
| Moderate (weekly use) | TopCashback + Too Good To Go + bank app | £25–£60/month |
| Active (regular, systematic use) | All cashback + grocery apps + price tracking + Shopmium | £70–£150/month |
The biggest gains come from using cashback for large purchases (insurance, broadband, holidays) rather than small retail purchases. A single broadband switch via TopCashback can earn £60–£100 in cashback — equivalent to months of grocery app savings.
What to Avoid
Not all money-saving apps are equally trustworthy:
- Unknown cashback apps with no FCA registration or verifiable company history — treat with caution. Check reviews on Trustpilot and the app’s registration on Companies House before connecting your bank account or personal data
- Apps that require bank account access — only connect your bank to FCA-regulated apps. Legitimate apps use Open Banking (which does not give the app ability to move money — read-only access only)
- “Free money” or referral schemes that require personal data beyond what seems reasonable
Stick to established, FCA-regulated providers for anything that accesses your financial accounts.
Staying Organised Across Multiple Apps
Using multiple apps simultaneously can become complicated. A simple system:
- Cashback (TopCashback/Quidco): check before any online purchase above £20
- Grocery cashback (Shopmium): review offers once a week before your shop
- Food apps (Too Good To Go): browse once or twice a week
- Price tracking (CamelCamelCamel): check before any Amazon purchase above £30
Fifteen minutes a week covers the most valuable checks. You do not need to use every app every day for them to add up.
