Costa Iced Oat Velvetino (UK Price & Calories 2026)
The Iced Oat Velvetino is for the Costa order where you want a cold coffee with a smooth oat-based texture, not just a plain iced coffee. Near an airport departure area on a casual weekend stop with a friend, I’d put it firmly in the sweeter drink lane; it worked better as a takeaway than something to sit with for ages.

Before you decide
- Small costs £4.95.
- Small is the listed size here, with a 189 ml portion.
- Small has 75 kcal with the default oat milk.
- Sugar is 7.8 g in the Small.
- Default milk is Oat.
- Coconut and soya milk swaps both don’t change price.
What you pay
The Iced Oat Velvetino price in the UK is £4.95 for a Small. That’s the only price shown in the provided 2026 information, so the buying decision is simple: you’re looking at one listed size, rather than choosing between a Small and a larger option.
Because there’s no bigger size price here to compare against, I wouldn’t describe a Medium as better value. The useful question is whether £4.95 feels right for a 189 ml iced oat-based coffee drink with 75 kcal. If you want a quick sweet cold coffee to carry with you, the Small makes sense. If you’re mainly chasing volume, there isn’t enough size pricing here to make that case.
The size I’d go for
I’d choose the Small, because it’s the listed size and the nutrition is fairly easy to judge: 189 ml, 75 kcal, and 7.8 g sugar. For a sweet or dessert-style drink, that keeps the order controlled without turning it into a larger commitment.
This is also why it suits a takeaway moment. The oat base is the main point of the drink, so you’re ordering it for texture and a softer coffee style rather than for a long, large drink. If Costa shows other sizes in-store, check the current board before ordering, because the figures here only support the Small decision.
How heavy is it really?
Iced Oat Velvetino has 75 kcal in Small. The Small also contains 7.8 g sugar, 2.4 g fat, 0.3 g saturates, 12 g carbs, 1 g protein and 0.14 g salt.
The main thing to notice is that this isn’t a high-calorie number for the listed Small, but it still reads as a sweet-leaning iced coffee because of the sugar figure and the oat-based style. If you’re choosing it because you want something creamy in texture without going for dairy milk as the default, the standard oat version is the baseline to use.
| Size | Portion (ml) | Energy (kcal) | Energy (kJ) | Sugar (g) | Fat (g) | Saturates (g) | Carbs (g) | Protein (g) | Salt (g) |
| Small | 189 | 75 | 315 | 7.8 | 2.4 | 0.3 | 12 | 1 | 0.14 |

Milk swaps and what actually changes
The default Iced Oat Velvetino is made with Oat as the default milk. Costa also lists Coconut and Soya as milk swaps for the Small, and both are +£0.00.
Coconut milk swap
Coconut is the biggest calorie drop from the default oat version. It changes the Small by -22 kcal and -88 kJ. It also changes sugar by 0 g, fat by -1.2 g, saturates by +0.3 g, carbs by -2.8 g, protein by +0.6 g and salt by -0.03 g.
Soya milk swap
Soya also lowers the calorie count, but by a smaller amount than coconut. It changes the Small by -14 kcal and -56 kJ. It also changes sugar by -0.6 g, fat by -0.9 g, saturates by 0 g, carbs by -3.3 g, protein by +2 g and salt by -0.03 g.
If your main aim is the lowest calorie version from the listed swaps, choose Coconut. If you care more about the protein change, Soya increases protein by 2 g compared with the default oat version.
Allergens to know
For the Small Iced Oat Velvetino, the allergen information provided is:
- Wheat: Cross Contamination Risk

- Barley: Cross Contamination Risk
- Oats: Contains
Allergen information can change — always check in-store before ordering if you have a food allergy.
Who should order this?
Order the Iced Oat Velvetino if you want a cold Costa coffee that puts oat milk texture at the centre. The Small is the sensible pick from the figures here: it’s £4.95, 189 ml and 75 kcal before milk swaps.
Skip it if you’re after a large-value drink, because there isn’t a bigger size comparison in these figures. I’d also skip the default oat version if your main goal is the lowest calorie option, because the coconut swap reduces the Small by 22 kcal at +£0.00.
My practical order would be the Small with coconut if I wanted to make it lighter, or the default Small with oat if I wanted the drink as intended around its oat-based texture. It feels best as a quick sweet cold coffee rather than a slow sit-down order.
