21 SAS Reserve Locations & Regional Recruiting Areas (2026)

By Deepak Shukla · Historical account and source-led commentary · Updated 7 November 2026

The Army's published SAS Reserve locations for 21 SAS cover London and the South East, Wales, the M3/M4 corridor, East Anglia and the South West. For 23 SAS the listing names the Midlands, Scotland and northern England. These are recruiting regions, not a directory of bases. If you're trying to work out whether applying is practical, the real question is what the journey, attendance and work commitments would mean for you.

The five broad regions listed for 21 SAS

As checked on the British Army Jobs website on 7 November 2026, the public 21 SAS locations list names London and South East, Wales, the M3/M4 corridor, East Anglia and the South West. The list is useful for orienting an enquiry, but it is not a map of units, an operational footprint or a list of places to turn up unannounced. The recruiting team can tell you which current process applies to you.

Where the same page places 23 SAS

The current role listing separately names the Midlands, Scotland and the North East and North West of England for 23 SAS. That does not mean the experience of every reservist is confined to one region, nor that an applicant should choose on geography alone. These are two distinct reserve regiments with a common official recruiting route.

The part of geography I remember

The practical challenge for me wasn't remembering a list of regions. It was arranging work and getting to where I needed to be, then having enough time and energy for the next commitment. A nearby unit might make travel easier, but the training still has to fit real life. That is why I'd ask the recruiting team about attendance and location before making decisions based on an old address online.

What to ask before you plan a long commute

Ask the recruiting team which unit covers your circumstances, where initial Army training would take place, whether travel is expected, what attendance could look like and how the schedule interacts with normal work. An answer from the team is more useful than a cached directory listing, especially when arrangements change. Do not publish or rely on unverified private meeting locations.

What the Army says about commitment

An official October 2025 Soldier magazine feature described significant training demands, readiness to deploy and an average UK service contribution of 60 reserve days for an SAS Reserve trooper or commander. An average in a dated article is not a guaranteed personal requirement or a substitute for the current joining terms. The underlying point is that this is an ongoing military obligation rather than a fitness challenge.

Location should not obscure the bigger decision

A short journey to a unit does not remove the challenge of training, time off work or family commitments. I ultimately chose not to attempt selection after doing preparatory Army training. That decision is part of my record, and it matters when assessing what a serious commitment might mean. Read the official regional page, then decide whether to begin a recruiting conversation.

What about searches for 21 SAS London or a specific base?

The Army publishes broad recruiting regions, including London and the South East for 21 SAS, not a guarantee of an individual detachment's exact public access arrangements. Before arranging a visit, confirm current contact and attendance instructions directly through the official recruiter. An internet map pin or an old forum address is not a substitute.

Sources and next step

The regions above come from the Army Jobs SAS Reserve role page reviewed 7 November 2026; the commitment observation is from the dated Soldier magazine recruiting feature. For current contact details and individual eligibility, use the official UK Special Forces Reserve page linked below, not a third-party address list.
