Honest answer first: yes, coffee roasting can be profitable in the UK — but the margin lives or dies on two things: your channel mix and your buying discipline. Roasters with the same roaster, the same skill and the same beans end up in wildly different places depending on who they sell to and how well they know their cost per kilo.
If you're roasting, or thinking about it, here's the unvarnished picture.
The squeeze: double-priced beans and 700 competitors
Start with the input cost, because everything else sits on top of it.
For business owners who want to take this further, the complete UK coffee shop accounting guide can help you put it into practice.
Arabica hit an all-time high of 440.85 US cents/lb in February 2025. By August 2026, it had eased to around 323 cents/lb — but that left green coffee at roughly double late-2023 levels. Lavazza warned in July 2026 that prices were unlikely to fall "for at least two years". At the specialty end, the 2024/25 Specialty Coffee Transaction Guide puts the median specialty green price at $4.39/lb FOB — before freight, before finance, before anything.
Now the competition. World Coffee Portal's UK Coffee Roasters Report counted 700+ roasters in the UK back in 2024. Most of them are chasing the same independent cafés with broadly the same pitch: great coffee, good service, wholesale accounts. That's a red ocean — the same one their café customers swim in, one step up the chain. When 700 roasters court a finite pool of cafés, price pressure flows uphill: the café can't raise prices easily, so it pushes back on the roaster, who's already paying twice what the beans cost two years ago.
Squeezed from both ends. That's the game. Profitable roasters aren't the ones who ignore this — they're the ones who engineer around it.
The maths every roaster must own: weight loss
Before comparing channels, one piece of arithmetic that quietly decides whether you're profitable at all: roast weight loss. Green coffee loses 15–18% of its weight in the roaster. Buy green at £10/kg and roast at a 16% loss, and your roasted coffee costs £11.90/kg before you've paid for gas, labour, packaging or the machine.

Skip that adjustment and every price you quote is built on a cost that's 15–18% too low — a margin leak on every single kilo you sell. At the August 2026 green prices quoted here, that mistake is twice as expensive as it was in 2023. We go deep on this — batch costing, stock valuation, how much green to hold — in Green Coffee, Stock and Cash Flow.
Channel economics: where the margin actually lives
Roasting isn't one business. It's three, sharing a machine. The margin shapes below are rules of thumb, not promises — your numbers will vary with volume, positioning and buying.
Wholesale: volume, thin margin, debtor risk. Selling to cafés moves serious volume — cafés typically pay somewhere in the £28–£35/kg range for roasted specialty coffee — but it's the thinnest margin of the three once you've absorbed weight loss, packaging, delivery and the account management cafés rightly expect. Two structural catches. First, wholesale margins are the most exposed to the green squeeze, because café customers resist price rises hardest. Second, wholesale means debtors: 30- and 60-day terms are common, so you pay for green months before your customer pays you. A roaster growing its wholesale book fast can be profitable on paper and gasping for cash — the growth itself soaks up working capital. Every wholesale account is also a concentration risk: lose one big café and a chunk of your volume goes with it.

Direct-to-consumer bags: better margin, and a VAT gift. Retail bags sold for home use are where the margin per kilo is strongest — a 250g bag typically retails at several times its roasted cost. And there's a structural advantage most new roasters don't fully appreciate: coffee beans and ground coffee sold for home use are zero-rated for VAT. Your café customers hand HMRC a sixth of every hot cup; your retail bag carries no output VAT at all, while you still reclaim input VAT on your costs. That's a genuine, legal, built-in edge — and it can even put a bag-heavy roaster in a VAT repayment position. The catch is spelled C-A-C: customer acquisition costs money (ads, content, market stalls, time), and postage eats margin on single-bag orders. DTC margin is earned in marketing, not in the roastery.
Subscriptions: recurring revenue, deferred obligations. The subscription model layers DTC margin with predictability — you know in week one roughly what you'll roast and ship all month, which transforms buying and cash planning. Two disciplines matter. Churn is the silent killer; a subscriber who leaves after three months may never repay what it cost to acquire them. And money collected for coffee you haven't shipped yet is deferred revenue — an obligation, not profit. Prepaid annual subscriptions feel like a cash windfall right up until you're roasting for twelve months against money you spent in month one. (More on how roaster accounting should handle this in our complete guide to coffee roaster accounting.)
The pattern: wholesale buys you volume and credibility, DTC and subscriptions buy you margin and cash flow. Very few roasters thrive on one channel alone — the profitable ones choose a deliberate mix rather than drifting into whichever channel knocked first.

Why mid-sized roasters get squeezed hardest
There's an awkward middle in UK roasting. Kitchen-table roasters carry almost no overhead and can price on passion. The big players buy containers directly, hedge forward, and spread fixed costs across serious volume. In between sits the mid-sized roaster: big enough to carry premises, payroll and a serious machine, too small for real buying power — paying near-spot prices for green while running big-roaster overheads. If that's you, the escape routes below aren't optional extras. They're the job.
The escape: four disciplines of profitable roasters
1. Know your cost per kilo roasted — to the penny. Green cost including freight and duty, weight loss, gas, labour, packaging, delivery: batch-costed, per SKU, per channel. Not "roughly". When green prices doubled, roasters who knew their numbers repriced within weeks; roasters who didn't donated their margin to their customers for a year.
2. Price forward, not backward. Given the August 2026 price comparison with 2023 levels and Lavazza’s July 2026 outlook, current replacement cost — not the price you paid for the pallet in your stockroom — is what your prices need to cover. Build contract reviews into wholesale agreements so repricing is a scheduled conversation, not a crisis.
3. Diversify the channel mix deliberately. Decide what share of revenue you want from wholesale, DTC and subscriptions, and market towards it. Every point of mix you shift from wholesale to zero-rated retail bags improves both margin and cash flow.
4. Take the profit first. Most roasters run profit as a leftover: revenue in, costs out, hope for the rest. Flip it. We run roaster finances on Profit First: Real Revenue = revenue minus green coffee and direct costs, allocations set on that, profit transferred first, and pots for VAT, PAYE and corporation tax so the bills are pre-funded — no more raiding the green-buying fund to pay HMRC. Kasey Anton's Profit First for Restaurants showed food businesses typically netting 2–6% can reach 7–20% with this discipline; we've adapted the method for cafés and roasters, with starter allocations we tailor per client. The mechanics are in Profit First for coffee shops — the roaster version adds one twist: your stockroom is a cash decision, so the buying budget gets its own pot too.
So — should you roast?
If you're hoping roasting is an easy margin upgrade from running a café, it isn't — it's a second business with its own working-capital appetite, arriving in the middle of the most expensive green market in memory. But if you'll do the unglamorous work — batch costing, forward pricing, a deliberate channel mix, profit taken first — roasting remains a genuinely good UK business, with a zero-rated retail channel most industries would kill for.
Start with the numbers. Our Roaster Batch-Costing Worksheet walks you through true cost per kilo roasted, channel by channel — grab the Roaster Batch-Costing Worksheet in the coffee resources hub. And if you'd like help building a finance function around your roastery — allocations, pots, weekly numbers — that's exactly what our Profit First service does. Book a Free Profit Meeting to discuss your numbers. Unlike traditional accountants who file your returns once a year and disappear, we work with you month by month, which matters rather a lot when your input cost can double between year-ends.
