Dairy & Cheese Plant Pre-Feasibility

Why Start With a Pre-Feasibility Study

Most failed dairy projects fail at the concept stage, not the construction stage — the wrong size, the wrong product mix, or economics that never worked once realistic milk and selling prices were put in. By the time detailed engineering is under way, a great deal has already been committed. A pre-feasibility study front-loads the hard questions while changing the answer is still free.

It is deliberately quick and approximate. The point is not a precise capital figure to two decimal places — that comes later from supplier quotations — but a sound, defensible answer to one question: at sensible assumptions, does this plant make enough margin, at a volume you can actually sell, to justify the capital? Get that right and everything downstream has firm foundations.

The Method — From Profit Target to Plant Size

The logic runs backwards from the outcome you want. Each step is simple arithmetic; the skill is in choosing assumptions that will survive contact with reality.

1. Set the target. Decide the annual profit that would make the investment worthwhile, and the payback period you can accept. That anchors everything else.
2. Convert profit to turnover. Divide the target profit by a realistic net margin. Dairy manufacturing in a typical year runs around 5% net; a good year can reach 15% or more, a bad year can lose money — so the plant must be sized to be comfortably profitable at the conservative end.
3. Convert turnover to volume. Divide turnover by the realistic selling price per tonne to get tonnes per year, then by working weeks, days and productive hours to reach the hourly capacity the plant must hit.
4. Establish the milk requirement. Multiply the litres of milk needed per tonne of cheese by the daily output to get daily milk intake — the number that drives reception, separation, storage and supply contracts.
5. Size and cost the plant. From the hourly capacity, size the vats, stretcher, brining, packing, utilities and building, then prepare a ready-for-quote specification for at least three equipment suppliers. Doubling capacity rarely doubles cost — pipework, installation and buildings do not scale linearly — so it is often worth building in headroom for expansion from the start.
6. Test viability. Build a cost-per-tonne model and check the margin against current milk and product prices, then stress it for the prices moving against you. If it only works in the best case, it does not work.

A Worked Example — Illustrative Only

The figures below are generic and illustrative, on a June 2026 basis, purely to show how the method flows. They are not a quotation and not specific to any client or project. A real study uses your products, your pack formats, your working pattern and live quoted prices.

*Indicative bulk price only; roughly equivalent to €4,500/tonne at mid-2026 exchange rates. Cheese prices move constantly and must be checked live for any real study.

At that hourly capacity the practical recommendation would usually be to specify a one-tonne-per-hour line and run reduced hours initially — the marginal cost of the larger line is modest, and it leaves clear headroom for growth without a second capital round.

The Cost-Per-Tonne Model

This is where viability is won or lost. The model below is again illustrative, per tonne of mozzarella at roughly 8,800 litres of milk per tonne, on a June 2026 basis. The single most important line is milk — in cheese, milk is the overwhelming majority of cost, so the whole project is essentially a bet on the spread between the milk price you pay and the cheese price you achieve.

**UK average farm-gate milk price was 33.99 ppl in April 2026 (Defra / AHDB). By-product credits (cream, whey butter) are volatile and shown indicatively. Depreciation, finance, maintenance, distribution and overheads sit on top of the net cash cost and are project-specific.

Against an indicative selling price of about £3,800/tonne, the net cash cost of roughly £2,900/tonne leaves around £900/tonne to cover depreciation, finance, maintenance and overhead before profit — which is exactly why the margin is thin and the assumptions have to be right.

Today's Numbers Are Not Yesterday's

A point that catches out anyone working from an older model: the three numbers that drive dairy economics have moved in different directions, so an out-of-date study can be confidently wrong. Since the mid-2010s, UK farm-gate milk has risen by more than half — from the low-20s pence per litre to around 34 ppl. Process-plant capital costs are up in the order of 45 to 50 percent over the same period on the standard plant cost indices. Yet bulk cheese selling prices are little changed and have softened recently, with EU average cheese down around a fifth year-on-year into 2026.

The implication is a genuine margin squeeze: the cost of making cheese has risen far faster than the price of selling it. Any feasibility model must therefore be built on current, separately-verified figures for each line — milk, energy, capital and product — and never by uplifting an old spreadsheet by a single inflation factor. (The plant cost indices are a useful escalator but are US-centred and intended for short look-backs, so they indicate the order of magnitude rather than a quotation.)

What We Deliver

The deliverable is a concise, honest document an investor or board can act on — including, where the numbers do not support it, the recommendation not to proceed. Independence means the verdict follows the figures, not the hope.

Frequently Asked Questions

What is a dairy or cheese plant pre-feasibility study?

A short, low-cost piece of work done before any detailed engineering or supplier quotation. It works backwards from a target profit to the turnover, then the production volume, then the plant size, milk requirement and indicative capital needed, and finishes with a cost-per-tonne model that tests whether the project is commercially viable at realistic milk and product prices. The aim is to confirm the idea is worth pursuing — or to stop it cheaply — before significant money is spent.

How do you size a plant from a profit target?

Start with the annual profit that would make the investment worthwhile and divide by a realistic net margin to get the turnover. Divide turnover by the product selling price to get tonnes per year, then by the working weeks, days and productive hours to get the hourly capacity. From that capacity the equipment, building and utilities can be sized, and the milk requirement per day calculated. It is a simple chain, but each assumption — margin, price, working pattern, yield — has to be realistic, and that is where experience matters.

How much milk does a cheese plant need?

It depends on the cheese and its moisture. As a rough guide, a higher-moisture mozzarella needs in the order of 8,500 to 9,000 litres of milk per tonne of cheese, while a leaner block needs around 10,000 litres per tonne. Multiply the litres per tonne by the daily cheese output to get the daily milk intake. Recovering protein and fat from the whey reduces the effective milk needed per tonne and improves yield.

What does it cost to build a small cheese plant?

A small modern cheese line of around one tonne per hour, with reception, separation, pasteurisation, CIP, brining, packing, utilities and building, is a multi-million-pound capital project. A meaningful figure only comes from quotations against a defined process specification, which is why the pre-feasibility produces a ready-for-quote scope to put to at least three suppliers. Be aware that process-plant capital costs have risen sharply since the mid-2010s, so any older estimate must be re-escalated to today before it is relied upon.

Why can't I use cost figures from a few years ago?

Because the three numbers that drive dairy economics have moved in different directions. UK farm-gate milk has risen by more than half since the mid-2010s trough, plant capital costs are up roughly 45 to 50 percent over the same period, while bulk cheese selling prices are little changed and recently softer. Using old input costs alongside today's selling price — or the other way round — gives a misleading margin. Every figure in a feasibility model has to be on a current basis and re-quoted for the specific project.

Do you keep our project information confidential?

Yes. Client names, locations, volumes and financials are confidential and are never published or reused. A non-disclosure agreement is put in place before any project-specific information is exchanged. The worked figures shown on this page are illustrative and generic, included only to explain the method.
