How to Feed a Family Well on a Budget

8 min read

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 up week after week, with some of it in the bin by Friday. Plan it, and it's far easier to feed everyone properly — real cooked meals, decent protein, fruit and veg, actual variety — without the bill drifting.

For a yardstick: UK households spent an average of £33.63 per person a week on food and non-alcoholic drinks to eat at home between April 2024 and March 2025, according to Defra's Family Food statistics. What your family spends depends on who's eating, what they like and where you shop, so treat that as a rough guide, not a target. Here's the structure that helps keep your own bill down.

Why the unplanned shop usually 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.

Five rules for a family week on a 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 less extra sneaks into the basket.

2. Let meals share ingredients

One of the easiest savings. If Monday's traybake and Wednesday's curry both use peppers, one pack does both jobs and less ends up in the bin. Planning meals together rather than one at a time is what makes one basket of veg stretch across seven days.

3. Cook once, eat twice

Batch-friendly dinners — chilli, bolognese, curries, traybakes — are easy to double, and hand you a ready-made lunch or a second dinner without cooking again. One cooking session, two meals, half the effort.

4. Kids eat the same food

Separate "kids' meals" are a cost and a chore. Most children can eat 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 roughly what it'll cost 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 the meals actually cost

In our own recipe library, dinners average £1.85 a serving (as of Sept 2026), and most main meals fall between £1.10 and £2.50 a serving — cheaper than a 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 (up to two children, free on both plans) — with ingredients shared across meals where possible, and an estimated cost for the whole shop before you step outside, from real supermarket prices: Aldi first, with Tesco, Sainsbury's and Asda filling the gaps.
