How to Save Money on Food Shopping in the UK (What Actually Works)
Food shopping has quietly become one of the biggest household costs. Not because we’re buying better food, but because prices have crept up on almost everything.
Our weekly shop used to sit comfortably under £80. These days, it’s frighteningly easy to drift past £100 without buying anything fancy. Same meals. Same shops. Just higher prices.
Over the last couple of years, I’ve tried pretty much every way to cut food costs — switching supermarkets, meal planning properly, using cashback apps, buying reduced food, and even buying food that’s technically “out of date”.
Some ideas saved pennies. Others knocked £20–£40 off our weekly food bill without changing what we eat.
This guide focuses on what actually works in the UK right now; practical, realistic ways to save money on food shopping that you can start using immediately.
How to save money on food shopping – quick wins
If you don’t want the detail, start here:
- Switch at least one shop per month to Aldi or Lidl
- Meal plan some dinners, not every meal
- Buy yellow sticker food and use the freezer
- Stack cashback and receipt-scanning apps
- Buy best-before food online in bulk
Do just a couple of these and you’ll usually see a difference within weeks.
Create a grocery budget (boring, but essential)
This is the least exciting step, and the most important.
Until you actually track what you spend, you’re guessing. We thought our food bill was “around £70 a week”. When I checked the bank statements properly, it was closer to £90.
You don’t need a perfect system. Just:
- Work out roughly what you spend on food each month
- Divide it into a weekly number
- Keep that figure in mind when you shop
If you want help, budgeting apps can do some of the work for you. But I’d still recommend doing it manually once, it’s eye-opening.

Meal planning without turning it into a chore
Meal planning doesn’t mean planning every single meal like a military operation.
What actually works is planning enough meals to stop panic spending.
If you know what you’re eating for four or five evenings, you’re far less likely to:
- Grab a takeaway
- Pop to the shop midweek “for one thing”
- Buy expensive convenience food
Batch cooking helps too. Meals like chilli, bolognese and curries are cheap, filling and freeze well. Bulk them out with vegetables and they go even further.
I don’t plan lunches perfectly. I don’t plan weekends perfectly. I just plan enough to stop the food bill spiralling.
Always shop with a list
This sounds obvious, but it’s one of the easiest wins.
A shopping list:
- Reduces impulse buying
- Gives you a rough idea of spend before checkout
- Stops “oh yeah, we need this” purchases
If you buy similar items most weeks, you’ll quickly learn what a £60 shop feels like versus a £90 one — and that awareness alone can save money.
Change your supermarket to save money
Most people shop at the same supermarket out of habit.
Around a quarter of UK shoppers use Tesco as their main store. It’s convenient and has good loyalty deals, but convenience costs.
Research by Which? consistently shows that Aldi and Lidl are typically 20–25% cheaper than the big supermarkets on a like-for-like basket.
You’ll see fewer brands and less choice, but even switching one shop per month can noticeably reduce your food bill.
And take a look at my post on the best supermarket loyalty cards to make sure you’re not missing out on extra bargains.
How supermarkets encourage overspending
Supermarkets are designed to make you spend more.
A few things to watch for:
- Premium products at eye level
- Cheaper own-brand items lower down
- Multi-buy offers that aren’t always better value
Always check the price per unit on the shelf label. With different sizes and constant promotions, this is often the only way to tell which product is genuinely cheaper.
Buying in bulk usually saves money, but only if you’ll actually use it.
Buy reduced food and use the freezer
Reduced “yellow sticker” food is one of the easiest ways to save money on groceries.
These items are usually reduced because they’re near their sell-by date, not because there’s anything wrong with them.
A few key tips:
- Morning reductions are usually small
- Evening reductions are often much bigger
- Most items can be frozen the same day
We regularly freeze reduced meat the day we buy it and use it weeks later with no issues. Fruit and vegetables often last longer than people expect too.
If you want the detail, I’ve written a full guide on when supermarkets reduce food and how to get the best yellow sticker bargains.
Don’t ignore discount stores
Aldi and Lidl aren’t the only places to save money.
Stores like Home Bargains and B&M are great for:
- Cereals
- Cleaning products
- Toiletries
- Long-life groceries
They mainly sell branded items at lower prices, and stocking up here can noticeably shrink the cost of a big supermarket shop.
Use apps to save money on food shopping
Apps won’t transform your finances overnight, but stacked together, they quietly shave money off your grocery bill.
Receipt-scanning apps
These are the easiest wins. You scan your receipt after shopping and earn points towards cash or vouchers.
They’re slow burners, but it’s money for something you’re already doing.
Cashback grocery apps
These offer cashback on specific products. Buy the item, upload the receipt, and get paid.
Savings vary, but £0.50–£5 per item is common. I’ve broken down the best options in my discount grocery apps guide.
Buy cheap food that would otherwise be wasted
We’re far too obsessed with dates on food.
“Best before” doesn’t mean unsafe. In most cases, food is still perfectly edible well after the date on the packet.
Websites like Approved Food and Best Before It’s Gone sell food close to, or just past, its best-before date at heavy discounts. Delivery costs mean it works best if you buy in bulk.
For fresh food, apps like Too Good To Go and Olio let you pick up surplus food from cafés, supermarkets and even individuals — often for free or a couple of pounds.
Food goes quickly, though. Hesitate and you’ll miss out.
Food shopping on a budget – final thoughts
You don’t need to do everything on this list.
When we focused on just three changes, planning a few meals, switching supermarkets occasionally, and buying reduced food, our food bill dropped noticeably within a month.
That breathing room matters.
And if things are genuinely tough, there’s no shame in asking for help. Organisations like The Trussell Trust can help you find local food banks offering free support when it’s needed most.

Frequently asked questions
How can I save money on food shopping quickly?
The fastest wins are switching supermarkets, planning a few meals each week, and buying reduced food you can freeze. These changes alone can cut £20–£40 a month for many households.
What is the cheapest supermarket in the UK?
On a like-for-like basket, Aldi and Lidl are consistently the cheapest according to consumer research. However, prices vary by location and offers, so it’s worth checking locally.
Are reduced and yellow sticker foods safe?
Yes. Reduced food is usually discounted because it’s near its sell-by date, not because it’s unsafe. Most items can be frozen the same day and used later.
Do grocery cashback apps really save money?
They won’t make you rich, but used together they can knock £5–£10 a month off your food costs with very little effort.
Is meal planning worth it?
Yes — even partial meal planning helps. You don’t need to plan every meal; just enough to avoid impulse spending and takeaways.
