The Real Cost of Iced Coffee for UK Cafés and How to Get the Margins Right
Iced coffee is no longer a seasonal line in UK cafés. The British Coffee Association has tracked growing demand for cold coffee drinks across the year, with the April-to-September window representing the highest volume but winter demand holding above where it sat five years ago. For café owners, that sustained demand is useful. The problem is that iced drinks carry a different cost structure from hot drinks, and most UK cafés price them as if they do not.
The result is a category that appears profitable on the surface and quietly compresses margins through the busiest months of the year.
Why Iced Coffee Costs More Than the Espresso Alone
The coffee is only one component. The additional costs that separate iced drinks from their hot equivalents are real, consistent, and rarely included in a per-drink cost calculation.
Ice
A single iced drink typically takes 150–200g of ice. At 40 iced drinks a day — a moderate summer volume for a busy high street café — that is 6–8kg of ice per day, six days a week. Cash-and-carry bag ice has a cost per kilogram. A countertop ice machine reduces that variable cost but introduces capital outlay and daily maintenance. Neither option is free, and ice rarely appears in a drink-by-drink margin calculation.
Cold cups and domed lids
Paper hot cups are a commodity. Cold cups with domed lids cost more per unit, and the gap has widened as UK suppliers reformulated away from single-use plastics. The difference per serve is modest. Across a summer of iced volume, it is not.
Straws
Paper straws, where provided, add a further cost per serve. The amount per drink is small on its own. Combined with the cup and lid differential, it contributes to a running overhead that hot drinks do not carry.
Labour
Labour typically accounts for 30–35% of revenue in UK hospitality businesses, according to UKHospitality. That proportion is sensitive to average drink time. An experienced barista makes a flat white in well under two minutes. An iced drink, particularly one with plant-based milk, a flavour syrup, or an extra shot, takes longer to build. Slower drinks during a Saturday rush have a measurable cost that does not show up in the ingredients.
Milk preparation
Cold milk does not steam. If you are making iced lattes with cold poured milk, the product is different from a hot latte. If you are steaming and then chilling, you are adding a process step. Either way, the workflow is not identical to a standard hot drink, and neither version is costless in time or preparation.
How UK Cafés Typically Price Iced Coffee
Two pricing methods account for most UK cafés. The first is charging the same as the equivalent hot drink. The second is adding a flat premium of 20–50p. Both are based on intuition rather than cost calculation.
Charging the same as the hot equivalent ignores all additional costs. The flat premium is a better approach, but the figure is usually a guess. If an iced latte costs 35–45p more to produce than a hot latte — accounting for ice, cup differential, straw, and additional labour — then a 30p premium means you are losing margin relative to the equivalent hot drink, not protecting it.
ONS CPI data for restaurants and cafés shows that prices in this category rose by more than 28% between 2021 and 2025 (index: 116.4 to 150.0, base year 2015=100). A flat pricing premium that felt adequate four years ago does not automatically reflect what the drink costs to produce today.
How to Calculate the Real Cost Per Iced Drink
Every iced drink cost calculation needs six inputs: coffee at your supplier cost per kg; milk at your delivered cost per litre; ice at your cost per kg or daily machine cost spread across expected volume; cup and lid at per-unit cost; straw if provided; and a labour allocation based on your hourly staff cost and the average time to produce the drink.
Once you have a total cost per drink, you can set a selling price against a target gross margin. Most hospitality operators aim for a beverage gross margin of 65–70%. If your iced latte costs 95p to produce and you are selling it for £2.80, your gross margin is 66%. If you are pricing it at £2.60 because that is close to your hot latte price, your margin is 63.5%. Across a high-volume summer week, the difference is significant.
The calculation takes 20 minutes to do properly. It is worth running once each spring before iced drink volume builds, and revisiting if your supplier costs change mid-season.
How Batch Preparation and Bean Choice Affect Your Margin
Two adjustments reduce the cost of producing iced coffee at volume without changing the price the customer pays.
The first is batch preparation. Cold brew made overnight in bulk costs less per litre than the labour required to pull individual espresso shots for each iced order during a peak period. Cold brew also uses less coffee per millilitre of finished drink than espresso-based recipes. A cold brew iced latte, costed and priced correctly, typically delivers a stronger margin than an espresso iced latte produced to order.
The second is bean consistency. Lighter specialty roasts can produce excellent iced coffee, but they are more sensitive to extraction variables and require precise grind control. Under the pressure of a busy summer service, that sensitivity costs time and produces more wastage. A medium-dark blend, roasted consistently and delivered fresh, is more forgiving. Caffé Prima supplies freshly roasted beans to UK cafés and hospitality businesses from £11.99 per kg, with a maximum of six weeks from roast to delivery, no minimum order, and free next-day delivery on orders over £45. For operators calculating cost-per-cup, a predictable delivery schedule and a consistent roast profile reduce the variables you have to manage.

The Calculation Has to Happen Before Summer
Iced coffee does not need a different management philosophy from the rest of your menu. It needs the same cost discipline applied to a product with a different cost structure.
The cafés that protect their summer margins are the ones that ran the numbers in March or April. The ones that discover the problem in July have already priced their busiest weeks incorrectly, and the margin they have lost does not come back.
UKHospitality publishes practical guidance on menu costing and pricing that is worth reviewing before the summer season. WRAP produces resources on reducing preparation waste in hospitality kitchens, which connects directly to the over-preparation risk in iced coffee batch production.
