Having outgrown their original brewery site in Summertown near Wimbledon, where they had been operating since 2011, By The Horns opted to create a new brewery at a different site in 2020. They chose a modern industrial unit on The Io Centre industrial estate in Salfords, near Horley, Surrey, which opened for brewing operations in June 2021, although they retain a link to their London roots by keeping the original tap room at The Phoenix open.

The Salfords site was subsequently upgraded to allow for occasional open days at weekends, which began in March 2023, and following the success of these events, BTH expanded into the neighbouring unit, also in response to increased demand, and in February 2024 started a series of Saturday openings to run in alignment with showings of the Six Nations rugby tournament on a large wall-mounted television. These events were supported by a local food van and beer was served via a mobile bar. These proved very successful amongst a diverse local, family-friendly audience, and August 2024 saw them open a fixed bar in the new unit, and a move to a regular Saturday opening schedule, often in tandem with a live music performance by a local band, and with good street food continuing to be provided by their outsourced partner via a van at the front of the premises. Consideration is currently being given to increasing opening hours beyond just Saturdays.

The new bar features six of their keg options; however only one handpump was installed, meaning the maximum number of cask beers to be found at the Salfords Tap is only 1. Nevertheless, many more of their cask portfolio can now be found in various pubs in the east Surrey area, and the brewers have a strategy to have more of their beers served in pubs further afield.
