How This Tool Works
📋 Purpose
Help UK households plan affordable, nutritious meals using real ingredient prices and ONS regional data.
⚙️ How It Works
- 1Enter your full UK postcode — the tool looks up your region via Postcodes.io and adjusts ingredient prices using ONS regional food expenditure data
- 2Set your household size (1–6 people) — ONS equivalisation factors are applied so a couple does not cost exactly double a single person
- 3Choose a dietary preference: All Foods, Vegetarian, Vegan, Gluten-Free, Dairy-Free, or Nut-Free to filter the meal library
- 4Select a planning horizon (3, 6, or 12 months) to see projected total food spend alongside weekly and monthly costs
- 5Review your weekly meal plan with per-serving ingredient costs, allergen flags, and daily nutrition vs NHS Eatwell Guide targets
- 6Check the Money-Saving Tips section and download your plan as CSV to take to the supermarket

Quick Tips
Jump-start your understanding with these essential tips
Supermarket own-brand staples (rice, pasta, tinned tomatoes, oats) are typically 30–40% cheaper than branded equivalents with nearly identical nutritional content. This planner uses own-brand prices as the baseline.
Meals that make 4 servings (like lentil curry or pasta bake) cost less per portion than single-serving meals. Freeze extras for quick weeknight dinners instead of ordering takeaway.
Root vegetables in autumn/winter and salad vegetables in summer are cheaper when in season. Frozen vegetables are always affordable and nutritionally equivalent to fresh.
WRAP estimates UK households throw away £700 of food per year. A weekly meal plan helps you buy only what you need and use leftovers effectively.
Step-by-Step Guide
Follow these steps to get the most from this tool
Your postcode is used to look up your region via Postcodes.io (a free, live API). This adjusts ingredient prices based on ONS regional food expenditure data — for example, London is typically 15–18% more expensive than the North East. Choose your household size (1–6 people) and the tool applies ONS equivalisation factors for economies of scale.
💡 Pro Tips:
- •Enter a full valid UK postcode (e.g. M1 1AA, SW1A 1AA, EH1 1YZ).
- •Household size affects total cost — two adults do not cost exactly double because of bulk buying and shared ingredients.
Select from All Foods, Vegetarian, Vegan, Gluten-Free, Dairy-Free, or Nut-Free. The tool filters its meal library to show only meals that match your preference. Choose a 3-month, 6-month, or 12-month planning horizon to see your projected total food spend.
💡 Pro Tips:
- •Vegetarian and vegan plans are often cheaper because plant proteins (lentils, beans, chickpeas) cost less per serving than meat.
- •If you have multiple dietary needs, start with the most restrictive to ensure all meals are suitable.
The results show your weekly, monthly, and horizon-total costs compared to both your regional average and the national average (£66.20/week per person, ONS Family Spending Survey 2023/24). Click any meal card to see individual ingredient costs, allergen warnings, nutrition per serving, and ingredient swap suggestions.
💡 Pro Tips:
- •Look at cost per serving — not just total cost — to compare meals fairly.
- •Check the Daily Nutrition section to see if your plan meets NHS Eatwell Guide targets for calories, protein, carbs, fat, and fibre.
The Money-Saving Tips section provides actionable advice across meal planning, shopping, nutrition, and cooking. Download your meal plan as a CSV file to take to the supermarket or share with your household. Re-run the tool when prices change or your household circumstances shift.
💡 Pro Tips:
- •Re-run seasonally — ingredient prices shift with seasons and supermarket promotions.
- •Compare vegetarian vs all-foods plans to see potential savings from meat-free days.

Deep dives for advanced users
Food prices vary across the UK. London prices are typically 15–18% above the national average, while Scotland and the North East tend to be 5–9% below. This tool uses ONS regional expenditure multipliers to adjust all 30 ingredient prices based on your postcode region. The multipliers come from the ONS Family Spending Survey which tracks actual household spending in each region.
A household of 2 does not spend exactly double a single person because of economies of scale — shared cooking oil, bulk rice, shared seasoning and condiments. The scaling factors used here (1 person = 1.00×, 2 = 1.75×, 3 = 2.40×, 4 = 3.00×, 5 = 3.20×, 6 = 3.40×) are derived from ONS equivalisation data. This means a couple saves roughly 12.5% per person compared to living alone.
The NHS Eatwell Guide recommends about 2,000–2,500 kcal per day for adults, with at least 50g protein, 30g fibre, and no more than 70g fat. This tool checks your plan against these targets. Budget-friendly high-fibre foods include oats (£0.15/100g), lentils (£0.10/100g), and wholemeal bread (£0.09/slice). Protein can be met affordably through eggs (£0.15 each), tinned tuna (£0.50/tin), and chickpeas (£0.08/100g).
