Healthy eating on a budget UK: 12 habits for a cheaper, healthier shop

The quick version

Healthy food is often among the cheapest in the shop: oats, potatoes, eggs, beans, lentils, frozen vegetables and tinned fish all fit the NHS Eatwell Guide. The savings come from habits: plan meals and write a list after checking what you have, compare unit prices per kg or litre rather than pack prices, try own-brand and value ranges, buy frozen, tinned and loose produce, swap some meat for pulses, and freeze food before it goes off. If you are pregnant or have a child under 4 and get certain benefits, check whether you qualify for Healthy Start.

Why healthy and cheap overlap more than you think

Look at the foods the Eatwell Guide is built on and many of them are basics: porridge oats, potatoes, rice, pasta, bread, eggs, milk, carrots, onions, frozen peas, tinned tomatoes and dried or tinned pulses. The British Dietetic Association's "Eat well, spend less" fact sheet makes the same point and lists baked beans, tinned mixed beans, chickpeas, lentils, eggs, milk, yoghurt, frozen chicken thighs, frozen fish and tinned fish as good-value protein.

What tends to push a food bill up is not the vegetables. It is convenience and extras: snacks, sugary drinks, ready meals, takeaways, and food bought on impulse that is thrown away later. That is good news, because those are the parts you can change without eating less well.

Two ideas sit behind every habit in this guide:

• Pay for food, not for packaging or waste. Loose, frozen, tinned and own-brand versions of the same food often cost less for the same nutrition.
• Price per kilo beats price per pack. A bigger or smaller pack, a multibuy or a loyalty price can hide what you are really paying, which is why the unit price exists.

The low-cost Eatwell plate

Here is each part of the Eatwell Guide with the kind of options that tend to be cheapest in UK supermarkets. If you want a refresher on how big each section should be, our plain-English Eatwell Guide explainer has the proportions and portion sizes.

Drinks are the easiest saving of all: tap water costs next to nothing, and the government's 6 to 8 glasses of fluid a day can come from water, lower-fat milk, tea and coffee.

Most overspending happens because decisions get made in the shop, when you are hungry, rushed and surrounded by offers. Move those decisions to the kitchen table.

1. 1
   Plan your main meals

   The BDA's first tip is to make a meal plan, particularly for main meals. Even planning four dinners stops the nightly "what's for tea" trip to the shop. If you are new to it, keep the plan short and reuse ingredients across meals so nothing is left over.

2. 2
   Shop your cupboards first

   Check the fridge, freezer and cupboards before writing the list. Half a bag of rice and a tin of chickpeas are the start of a meal, and buying them twice is money in the bin.

3. 3
   Write the list, then stick to it

   A list written from your plan is the cheapest tool there is. Allow one or two flexible lines, such as "a fruit on offer", so you can still take advantage of genuine deals.

4. 4
   Shop after eating, and not in a rush

   The BDA suggests shopping when you are not hurried and after a meal, so hunger is not choosing your basket. Online shopping can help too, because you can see the running total and compare prices without the displays.

1. 5
   Read the unit price, not the big price

   The small print on the shelf label shows the price per kilogram or litre. Under the Price Marking (Amendment) Order 2024, from 1 October 2025 shops covered by the rules must show unit prices consistently per kg or litre, and loyalty scheme prices and multibuy deals must carry a unit price too. That makes it much easier to see whether the big bag, the small bag or the "3 for 2" is really the best value.

   The BDA's advice is to use unit pricing to compare packs of different sizes, but to buy only what you will use. A cheaper-per-kilo sack of potatoes is not a saving if half of it sprouts.

2. 6
   Try the own-brand or value version

   The BDA notes that value brands often taste just as good for a lower price. Try one product at a time, starting with basics where the recipe barely changes: oats, tinned tomatoes, pulses, rice, pasta and frozen veg.

3. 7
   Look high, low and loose

   Cheaper items are not always at eye level, so check the top and bottom shelves. Loose fruit and vegetables are often cheaper than packaged, seasonal produce is usually better value, and "wonky" ranges are just as nutritious.

4. 8
   Use reductions, but only for food you will eat or freeze

   Ask staff when fresh food is usually reduced. A reduced pack of chicken or bread is a bargain if it goes straight into tonight's meal or the freezer, and a waste if it sits in the fridge.

The front-of-pack colours are worth a glance while you compare. Two own-brand pasta sauces can differ a lot in salt; our guide to reading red, amber and green labels shows the cut-offs so you can choose in seconds.

Fresh, frozen or tinned: choosing the cheapest form

The NHS is clear that almost all fruit and vegetables count towards your 5 A Day, whether they are fresh, frozen, canned, dried or juiced. So the cheapest form that you will actually eat is usually the right one. The BDA describes frozen fruit and vegetables as good value and highly nutritious, because they are frozen soon after picking, and points out they are already prepared, which saves time.

Dried fruit counts too: the BDA notes a 30g cupped handful is a portion. Fruit juice and smoothies count only once a day however much you drink, and the NHS suggests keeping them to 150ml a day in total, so whole fruit is usually better value as well as more filling.

Protein that costs less

Protein is often the most expensive part of a meal, and it is where the biggest savings sit. Pulses do double duty: they are a protein food, and beans and pulses also count as one of your 5 A Day.

Three ways to use them:

• Stretch the mince. Replace a third or half of the meat in chilli, bolognese or cottage pie with lentils or beans. Most families barely notice.
• Go meat-free once a week. The BDA suggests at least one meat-free meal a week as a simple way to cut costs: a bean chilli, dal with rice, or a vegetable omelette.
• Use tinned oily fish. The NHS recommends at least 2 portions of fish a week, including 1 oily. Tinned sardines and mackerel on wholemeal toast are one of the cheapest ways to get there.

Dried lentils and split peas are often cheaper again than tinned. Red lentils need no soaking and cook in about the time it takes rice, which makes them an easy first step.

1. 9
   Cook from scratch, in bigger batches

   The BDA points out that cooking at home, including a takeaway-style meal, can be cheaper, and suggests bulk or batch cooking where you can. A double pan of chilli or soup costs little more than a single one and gives you a second meal for the freezer.

2. 10
   Freeze before it goes off

   Bread freezes well, and slices toast straight from frozen. The Food Standards Agency says you can freeze food right up to midnight on its use-by date, so meat or fish you cannot cook in time does not need to be wasted. Label and date what goes in.

3. 11
   Know which date matters

   The FSA explains that a use-by date is about safety, so do not eat food after it, and do not use the sniff test on it. A best before date is about quality: food can be eaten after it, so check whether it still looks and smells fine before throwing it out.

4. 12
   Use the whole vegetable

   Leave skins on potatoes and carrots where suitable, which also keeps more fibre, and turn peelings, wilting veg and stalks into soup or stew. Plan a "use it up" meal once a week, such as an omelette, fried rice or soup.

Once cooked food is in the fridge, the FSA advice is to eat it within 48 hours or freeze it, and to reheat it until steaming hot.

Straight answers to the questions people ask about budgets

Help with food costs you may be entitled to

Many families who qualify for food support never apply. If money is tight, check these before cutting back on food.

If you are pregnant, Healthy Start can make a real difference to the cost of fruit, vegetables and milk; our pregnancy meal plan for the UK shows how those foods fit a balanced week.
