Food prices in the UK have risen sharply over the past two years. The average household now spends £68 per person per week on food — but with a structured meal prep approach, you can comfortably eat well on £25–35 per week. This guide is built around 2026 UK supermarket prices, with specific references to Tesco, Aldi, and Lidl.
What's Changed in 2026
Meal prepping in 2026 looks different from three years ago. Chicken breast prices have stabilised after the 2023–24 surge, but convenience food costs have kept climbing. A meal-deal at a supermarket now runs £4–4.50. A mid-range takeaway for one is £12–16. The gap between home-cooked and bought-in food has widened — which means the financial case for meal prep is stronger than it's ever been.
Current Tesco prices (as of early 2026) that form the backbone of budget meal prep:
- Tesco Chicken Thighs (1kg, bone-in) — £2.70–3.20
- Tesco Everyday Value Eggs (12) — £1.85
- Red lentils (500g, own brand) — 60–75p
- Tinned chopped tomatoes (400g) — 35–45p
- Tinned tuna in brine (4-pack) — £2.50–3.00
- Basmati rice (2kg) — £2.50
- Frozen mixed vegetables (1kg) — 90p–£1.10
These seven ingredients can anchor four to five days of meals for one person at approximately £13–15. Everything else — seasoning, oils, canned goods — is cheap at volume and lasts weeks.
The Right Way to Set Your Budget
Most budget meal prep advice picks a round number — "£25 per week" — without explaining why. Your actual number depends on two things: your calorie target and your protein target. Higher protein requirements cost more because protein is the most expensive macro per calorie.
A person eating 1,800 calories with a 130g protein target can achieve that for £22–26 per week. Someone eating 2,500 calories with a 180g protein target will need £30–38. The maths isn't complicated — it's just rarely written down. Start by finding your targets using our TDEE calculator and protein calculator. Once you have those numbers, you can build a plan that actually fits.
The 4 Staple Categories That Drive Budget Meal Prep
Every successful budget meal prep plan is built around the same four categories. Vary the recipes, but keep coming back to these:
1. Cheap Protein Sources
Eggs, chicken thighs, lentils, tinned tuna, minced beef (20% fat), and tinned chickpeas. These deliver the highest protein per pound of any food in UK supermarkets. Chicken breast is fine but overrated at the price — thighs deliver more flavour and cost 30–40% less per kilogram.
2. Slow-Release Carbohydrates
Oats, brown rice, wholemeal pasta, sweet potato, and canned beans. Buy dry goods in bulk (2kg bags vs. 500g bags) and you cut the unit cost in half. A 2kg bag of basmati at Tesco costs around £2.50 — enough for 10+ portions. A 500g bag costs £1.10, which works out to 220% more per gram.
3. Frozen Vegetables
Frozen broccoli, mixed veg, peas, and spinach match fresh on nutrition, cost 40–60% less, and last months rather than days. This alone eliminates the biggest source of food waste in meal prep — the soft veg that doesn't survive until day 4.
4. Condiments and Spices
A £1 jar of cumin, a bottle of soy sauce, a tube of tomato puree, and a bulb of garlic transform the same ingredients into five completely different meals. This is the underrated budget multiplier: if your spice rack works, you can rotate three proteins across seven days without eating the same thing twice.
A Sample Week Under £28
Here's a real meal plan built around 2,000 calories and 150g protein per day, costed at current Tesco prices:
- Sunday prep (2 hours): Batch cook chicken thighs (1kg), red lentil dal (500g dry lentils), hard-boil 12 eggs, cook 500g dry basmati rice
- Breakfast (x7): Overnight oats — 60g oats, 150g Greek yoghurt, frozen berries — 380 kcal, 22g protein — 55p/day
- Lunch (x7): Chicken and rice bowl — 150g cooked chicken thigh, 150g cooked rice, frozen mixed veg — 480 kcal, 42g protein — £1.15/day
- Dinner (x5): Red lentil dal with naan — 420 kcal, 30g protein — 75p/day
- Dinner (x2): Tuna pasta bake — 2 tins tuna, wholemeal pasta, tomato sauce — 520 kcal, 48g protein — £1.40/serving
- Snacks: Hard-boiled eggs (2/day) — 140 kcal, 12g protein — 30p/day
Total weekly cost: approximately £26–28. This plan delivers roughly 1,950–2,100 calories and 148–162g protein per day across the week.
Where Aldi and Lidl Beat Tesco
Tesco is used as the baseline here because it has the widest coverage, but Aldi and Lidl consistently undercut on core staples:
- Eggs: Aldi's 12-pack runs £1.55–1.65 vs Tesco's £1.85
- Chicken thighs: Lidl's Birchwood Farm range averages £2.50/kg vs £3.00 at Tesco
- Greek yoghurt (500g): Aldi's Everyday Essentials is typically 79–89p vs £1.30 at Tesco
- Frozen salmon fillets (400g): Lidl consistently prices at £3.99 vs £5.00+ at Tesco
If you're near an Aldi or Lidl, doing your protein shop there and filling gaps at Tesco can save £5–8 per week — which adds up to £250–400 annually.
Common Budget Meal Prep Mistakes in 2026
Three patterns that consistently derail people:
- Buying fresh veg for all 7 days. Anything green that won't last — buy frozen. Save fresh salad and herbs for the first two days only.
- Not using the reduced aisle. Most UK supermarkets mark down meat between 6–8pm and 7–9am. Reduced chicken or mince freezes for up to 3 months and cuts your protein cost by 30–50%.
- Over-complicating recipes. Four ingredients and one spice combination beat three different complex recipes every time. Complexity increases prep time, introduces failure points, and makes the plan harder to repeat next week.
Let the Numbers Do the Work
The most common reason budget meal prep fails isn't willpower — it's not knowing whether the plan actually hits your targets. If you're guessing at calories and protein, you'll either under-eat, over-spend, or both. Use our meal planner to generate a full 7-day plan based on your exact calorie and protein targets, automatically optimised around the cheapest UK ingredients available. It takes two minutes and removes the guesswork entirely.
