How We Assessed These Roasters
Our assessment criteria followed the methodology used by BalanceJournal.co’s Best Coffee Roasters London 2026 guide: roast quality, sourcing transparency, online availability, subscription options, and visit-worthiness where applicable.
As that guide notes: “A roaster with exceptional beans but no public-facing space still belongs here. A roaster with a beautiful cafe but average coffee does not.”
We weighted online availability and national UK delivery as essential criteria this guide is specifically for buyers who cannot or do not want to visit London in person.
1. Square Mile Coffee Roasters
Location: Walthamstow, East London (founded 2008) Website: squaremilecoffee.com
Square Mile Coffee Roasters was co-founded by James Hoffmann (2007 World Barista Champion) and Anette Moldvaer. According to BalanceJournal.co’s 2026 London roaster guide, there is a queue outside the Walthamstow roastery on Saturday mornings which tells you everything about the brand’s standing.
Square Mile focuses on seasonal single-origin coffees sourced through direct relationships with producers. They are known for consistency, precision, and the high quality of their origin information and brewing guidance provided with each coffee.
Hoffmann’s influence: James Hoffmann’s YouTube channel, books, and coffee research have made Square Mile the most internationally recognised London roaster. Buyers who follow Hoffmann’s work already know Square Mile. For buyers who do not, it is the correct starting point for exploring London specialty.
Online access: Square Mile ships nationally with £2.50 delivery (not free). Subscriptions available. Whole bean primarily. 350g bags at £12.50.
Best for: Specialty enthusiasts who want London’s most respected single-origin coffees. Filter and pour-over drinkers who want precision and seasonal rotation.
2. Ozone Coffee Roasters
Location: Shoreditch, East London (founded 1998 in New Zealand, London since 2012) Website: ozonecoffee.co.uk
Ozone started in 1998 as a small roastery in a provincial New Zealand surf town and expanded to London in 2012. This New Zealand heritage is visible in their coffee culture flat white expertise, milk-forward espresso precision, and a community-first approach that reflects the cafe cultures of Wellington and Auckland rather than the traditional Italian espresso tradition.
Ozone is a certified B-Corp independently verified for environmental and social performance. According to the HighNote Roasters London specialty guide, Ozone Coffee stands out among the best London coffee roasters for its varied subscriptions, specialty-grade coffee, ethical sourcing, and superb customer service.
What makes Ozone distinct: They roast on-site at Shoreditch with the equipment visible from the cafe. Their coffee is specialty-grade with clear origin documentation. The B-Corp certification distinguishes them from roasters who make environmental claims without independent verification.
Online access: Ozone ships nationally across the UK. Subscriptions available with multiple roast levels and origins. Free delivery over a threshold.
Best for: Buyers who want B-Corp verified environmental credentials alongside specialty quality. Buyers with New Zealand or Australian connections who want that coffee culture in the UK.
3. Dark Arts Coffee
Location: Hackney, East London Website: darkartscoffee.co.uk
Dark Arts is one of the UK’s most distinctively branded specialty roasters. As described by Balance Coffee’s UK roasters guide: “Arguably one of the most outlandish and coolest roasters ever to grace the UK coffee market.” The branding is bold and theatrical. The coffee behind it is genuinely specialty-grade.
Dark Arts roasts in Hackney and ships nationally. Their coffee tends toward bolder, more expressive profiles than the precision-light style of Square Mile. They work with single-origin lots and their own blends.
Subscription pricing: Approximately £10.50 per 250g bag with £3.50 delivery (not free). Subscription available for regular orders.
Online access: Dark Arts ships nationally across the UK. Website at darkartscoffee.co.uk.

Like Ozone, the New Zealand heritage means Allpress has deep expertise in espresso and milk-based drinks specifically.
