How to Feed a Family Well on £80–90 a Week

Food is one of the few household bills you can actually control — and one of the most stressful to control badly. Wing it, and a family food shop creeps past £120 with half of it in the bin by Friday. Plan it, and two adults plus a child can eat properly — real cooked meals, decent protein, fruit and veg, actual variety — for roughly £80–90 a week at UK supermarket prices.

That number isn't a best-case fantasy. It's what a planned week genuinely costs when every meal is decided before you shop. Here's the structure that gets you there.

Why the unplanned shop always costs more

Three things quietly inflate a family food bill:

• Duplicate buying — another jar of curry paste, another bag of rice, because you can't remember what's in the cupboard
• Orphan ingredients — the half-bunch of coriander or two-thirds of a pack of mince bought for one meal with no plan for the rest
• Panic meals — the Thursday takeaway or freezer pizza because nothing was defrosted and nobody had a plan

None of these are cooking problems. They're planning problems, and they respond to structure faster than to willpower.

The five rules of a family week that stays on budget

1. Plan all the meals, not just dinners

Dinner gets all the attention, but breakfasts, lunches, and snacks are where unplanned spending leaks. A week where all 5 daily meals are decided is a week where the shop covers everything — and nothing extra sneaks into the basket.

2. Let meals share ingredients

The single biggest saving. If Monday's traybake and Wednesday's curry both use peppers, one pack does both jobs and nothing rots in the drawer. Planning meals *together* rather than one at a time is what makes a £15 basket of veg stretch across seven days.

3. Cook once, eat twice

Batch-friendly dinners — chilli, bolognese, curries, traybakes — cost pennies more to double and hand you a free lunch or a second dinner. One cooking session, two meals, half the effort.

4. Kids eat the same food

Separate "kids' meals" are a cost and a chore. Children can eat exactly what the adults eat, portioned for their age — smaller amounts of the same bolognese, the same traybake. One plan, one shop, one pot.

5. Know the bill before the shop

This is the rule that holds the others together. When the week is planned against real supermarket prices, you know it's an £85 week before you leave the house — and you can swap a dinner out *before* it breaks the budget, not discover the damage at the till.

What that week actually looks like

A realistic planned week for two adults and a child, shopping at Aldi, Tesco, Sainsbury's or Asda, lands around £80–90 with dinners averaging about £1.72 a serving. Most individual servings across a good recipe library fall between £1.10 and £2.40 — cheaper than any takeaway, and a fraction of a delivered meal.

You don't need an app to apply the five rules. A pen, a supermarket receipt, and an honest hour on Sunday will get you most of the way.

Where Plan X Prep comes in

What an app adds is doing this automatically, every week: Plan X Prep builds the full 7-day plan around your household — adults' macro targets, children's age-appropriate portions (kids are always free on both plans) — with every ingredient shared across meals where possible, and the whole shop costed against real prices at Aldi, Tesco, Sainsbury's and Asda before you step outside.

Every meal planned. Every penny tracked. Join the waitlist and we'll email you the moment we're live.
