How we price

Two prices, and where they come from

You pay a one-off price for the supplies and a monthly storage fee. Both are built from the published prices and estimates listed below, plus our margin. Price confirmed before you pay.

Assumptions

What we've estimated

  • Volumes (water 0.044 cu ft per litre; food 1.1 cu ft per 24,360 kcal; equipment 2 / 4 / 8 cu ft per tier) are estimates.
  • Equipment costs (£150 / £450 / £1,200 per tier, scaled by household) are estimates.
  • Outside-London storage is estimated at 0.629 × London rates (UK vs London 25 sq ft medians).
  • Tinned & bulk staples at £1.00 per 1,000 kcal is an estimate (a blend of oats £0.85/kg, rice £1.19/kg and tins).
  • Tinned & bulk volume (0.6 cu ft per 24,360 kcal) is an estimate. 1 tray = 10,000 kcal.
  • 75 sq ft (£76.93/wk, interpolated) and 150 sq ft (£138.10/wk) London prices are estimates. Above 150 sq ft we use several 150 sq ft units.
  • Size comparisons (wardrobe, shed, garage and so on) and the unit drawings are estimates for illustration.
  • See your supplies: kit is £450 and 4 cu ft per two people (estimate); the water filter option stores 25% of the water (estimate).
  • Floor area assumes crates stacked 6.5 ft high at 70% packing efficiency — an estimate.
  • Water: 4 L per person per day at £0.30/L. Months are 30.4 days. Meals are three per person per day.
  • Fuel, power banks and batteries are kept at home, in line with typical storage licence terms.
  • The custom builder uses the same food, water and kit rates as See your supplies; its Standard tier matches the packages.
  • Year one = the one-off supplies price + 12 × the monthly storage fee, using the rounded prices shown on each package.
