Union Coffee coffee review

What Union Coffee sells, what it costs against the rest of the market, and who should buy it.

Updated 3 September 2026Written by the We Try Coffee team

Union Coffee sells 19 coffees in the UK and the cheapest comes out at 59p a cup, which is less than most of the ground coffee we track. Cheap coffee is easy to find and hard to trust, so the useful question is not whether it is cheap. It is what the range actually contains, and whether the bag doing the heavy lifting is the one you would want.

Short answer

Easy-drinking coffee with caramel and chocolate about it, for below the going rate.

What kind of roaster this is

Union Coffee sells whole bean and ground in the UK, and we track 19 of their coffees, in 1kg.

Expect blends here rather than named farms: 95% of the classified range is blended. The trade is a familiar one. You give up the story on the label and you get a cup that does not drift between orders. The buying reaches 9 countries across the range, which is a wide book for a brand this size. The roasting spans 3 of our five levels, so there is a genuine choice to make inside the range rather than one house style applied to everything. Every bag we list is a kilo or more, which is what pushes the per-cup figure down and also what makes this a bad fit if you drink slowly, since coffee is past its best four to six weeks after roasting.

What Union Coffee coffee costs

The range runs from 59p to 100p a cup across 19 products. That is a 1.7× spread inside a single brand, which is why "is Union Coffee expensive" is the wrong question; the right one is which bag you pick. The cheapest is House Roast in the 1kg, and the dearest is João Hamilton in the 1kg.

Bags themselves run £32.95 to £55.50. Ignore that column. A bigger bag costs more and almost always costs less per cup, which is the only number that follows you home.

The one to buy

If you buy one thing from Union Coffee, buy House Roast. At 59p a cup it comes in around 16% under the median for ground coffee, and that is measured against every brand in our catalogue rather than against Union Coffee's own list prices. Nothing else in the range gets close on that test.

What that costs over a year

How much coffee do you drink?
  • Union Coffee£0.59 per cup£433
  • Typical ground£0.71 per cup, our median£516

At 2 cups a day, Union Coffee costs £83 less a year than the typical ground coffee we track. That is the same coffee habit, bought better.

How Union Coffee tastes

We have not tasted Union Coffee, so we are not going to invent a tasting note. A flavour score we did not earn would be worth less than none, and this section would be the easiest place on the site to quietly make one up. What we can show you is measured: where every coffee in the range sits on our own five-point roast scale, and which origins go into it. Roast is the strongest single predictor of whether a cup arrives bright and fruity or dark and chocolatey, so it is the closest honest answer to what this brand is like to drink.

How Union Coffee roasts

Every coffee standardised onto our own five-point scale rather than the roaster's. Read these as tendencies: origin, process and how you brew all move the cup.

Who it suits

  • People who found something they like and want it to taste the same next year, which is what a blend is for.
  • Households getting through real volume. The kilo bags are the whole value case, and they only work if you drink them fresh.
  • People who want to choose their own roast rather than take the roaster's word for it, since the range covers 3 of our five levels.

Is it good value?

Our test is simple, and it is the same one we apply to everything: cost per cup against the median for the same format. Union Coffee clears it comfortably on at least one product, which more brands fail than pass. Worth knowing that the saving is concentrated in the larger bags rather than spread evenly, so buying the small size gives most of it back.
