Grow a grocery
A blueprint for starting a co-operative wholefood shop
An AI-generated audio overview based on Unicorn's blueprint. Around 20 minutes. You can listen to it for a summary of their model alongside links to their full guide.
This document sets out the blueprint we are using to plan the business. It replaces our previous adaptation of the Unicorn Grocery guide. We have removed their text to avoid confusion. If you want to read Unicorn's original guide, you can find it directly on their website.
Want to start a co-operative grocery?
This guide is a practical blueprint for starting a worker-owned wholefood grocery in a medium-sized UK city. It draws on our experience designing and planning SPRoUT in Leicester.
Setting up a food co-operative is a demanding task. It needs business discipline and operational competence. We hope these notes make starting your own shop easier.
We model our project on Unicorn Grocery in Manchester. We've adapted our plans for the economic and spatial realities of starting a smaller shop in Leicester.
The SPRoUT model: phased development
Our approach divides the project into three distinct phases to manage financial risk.
Phase 0 is the founder holding phase. During this stage, one or two founders carry the planning work and establish the initial structure.
Phase 1 is the proof grocery. We plan to open a shop with a focused range of everyday ingredients to prove the business model works.
Phase 2 is the earned expansion. We'll expand our footprint and range once the shop floor operations are stable and profitable.
We planned a starting scale of 500 to 650 square metres to ensure buying power and space for bulk packing. We're currently focusing on a smaller footprint of around 300 square metres for our first physical shop to keep rent and rates manageable. If a permanent building does not work out, we may use a modular shipping container layout as a temporary Phase 1 staging option.
Leicester demographics and market
Leicester has a different population spread compared to South Manchester where Unicorn trades. South Manchester has a high density of customers who seek wholefoods in a single neighbourhood. Leicester's customer profile is less concentrated but exists across the city.
A well-located site with good road links can draw from the wider catchment. Leicester city has a population of 380,000, and the wider county exceeds 700,000.
Leicester has a significant cost advantage. Commercial rents for trade counter and industrial units run between 6 and 12 pounds per square foot per year. A 300 square metre unit costs around 25,000 to 40,000 pounds per year. Business rates on units with rateable values below 12,000 pounds qualify for small business rate relief, reducing rates to zero.
Survey insights and shopper habits
We ran a community survey to test our assumptions. The results show high interest but also reveal a key shopping habit. Shoppers will switch to SPRoUT only if we match supermarkets on convenience and price. Ethical principles reinforce their decision but do not drive the switch.
Out of 143 respondents, 84 confirmed they are likely or very likely to shop with us. This is 59% of respondents. Even a 1% capture rate of the catchment population supports over 800 weekly visits.
The survey shows a median household grocery spend of 75 to 100 pounds per week. We assume a starting average basket spend of 22 pounds, which is a 25% share of a household's weekly shop.
Travel willingness is high. The survey shows 86% of respondents are willing to travel over 1km, and 52% are willing to travel over 4km to shop with us.
The grocery spine: core everyday ingredients first
We prioritize a disciplined range of 120 to 180 core everyday lines. Everyday habits are built around everyday ingredients. If these basic ingredients are not dependable and fairly priced, the store cannot support real cooking.
Our core range has fresh fruit and vegetables, rice, pasta, oats, flour, plus pulses and tinned tomatoes. We also stock plant milks, cooking oils, and basic household soap.
We do not stock animal products. We focus on unrefined wholefoods over highly processed items to support resource efficiency and health.
Layout and operations: Model site
We have modeled our layout and operations around a typical site of approximately 300 square metres plus, ideally on a single level. While we initially evaluated a unit on Abbey Lane, we have ruled it out due to high flood risks and are actively searching for alternative premises of a similar size.
Our layout split is longitudinal. We divide the building north to south into two halves. Ground-floor retail occupies the west side and the south base in an L-shape. The warehouse and back-of-house operations occupy the north-east section. This separation ensures customer and worker flows do not cross.
The main loading shutter is in the warehouse zone. The forklift has a clear route from the shutter to the storage areas.
We will place a walk-in chiller of 20 square metres in the south-east corner of the warehouse. The staff door is 2m wide to allow pallet trucks to move bulky stock directly from the warehouse to the retail floor.
Governance and ethics
We are designing SPRoUT as a worker-owned co-operative. The workers who run the shop will own the business on a one-member, one-vote basis. There are no external equity investors, and the business cannot be sold to private buyers.
We will raise capital using community loan stock instead of a community share offer. Community shares give shareholders voting rights. This is not compatible with complete worker control. Loan stock pays a fixed interest rate and keeps control with the workers.
Our Structural Ethics Charter sets out our principles. Profit is not our purpose. We will reinvest surplus into wages and keeping everyday ingredients affordable. We will pay wages at or above the real Living Wage.
We do not use moral pressure to persuade customers. We focus on competence and fair pricing. Trust comes from daily experience, not branding.
Unicorn grocery reference
Our model is inspired by Unicorn Grocery in Manchester. They have traded successfully as a worker-owned co-operative since 1996.
