H.R. Higgins are London's venerable coffee and tea merchants, trading from their Mayfair shop-cum-cafe on Duke Street since 1942. A Royal Warrant holder with over eight decades of history, they're the kind of specialty coffee roaster that blends old-world pedigree with a genuinely curious buying program — their first Burundi coffee (Giku Hill) and a honey-process El Salvador are recent additions to the lineup. Expect house blends, single origins, seasonal releases, and decaf options, backed by free UK delivery over £75 and a subscription service to keep your grinder fed. They also run tasting masterclasses for those wanting to dig deeper.
