Reachable Buyer Map

Prepared for Aytekin Guclu · London Defence R&D · United Kingdom · August 2026
From the outside, London Defence R&D reads as a UK manufacturer of counter drone detection, effectors and command software, positioned in its own words for the security and defense sectors. In this market first contact usually happens through a framework, a prime or a trade show floor, which reaches whoever is already mid procurement and is quiet about everyone else. This map is everyone else: the UK organizations that own airspace they cannot afford to lose, who signs inside each one, and roughly how many there are.
Police forces and the specialist forces
The shortest list on this page and the one with the most repeatable buying pattern, because a force that adopts detection tends to be watched by nearby forces and by the national leads who sit across them.
Who signs: assistant chief constable for operations, head of specialist operations, force lead for uncrewed systems, and the category manager in the regional buying hub who actually issues the paper.
45 to 50
UK territorial forces plus the specialist forces covering transport, the defence estate and civil nuclear
Prisons and the secure estate
The segment with the clearest and most public problem, since contraband delivery by drone is reported openly and repeatedly. Buying is split: the establishment feels the pain, the national security function sets the standard, and a central framework carries the money.
Who signs: governor, head of security at the establishment, the national security group lead, and the framework buyer at the centralized commercial function.
120 to 140
prison establishments across England, Wales, Scotland and Northern Ireland
Airports with scheduled passenger traffic
The segment where a single incident is measured in cancelled flights, so the case for detection is already made internally and the argument is about which system rather than whether. Several hundred smaller licensed aerodromes and private airfields sit below this line and are not counted in the band.
Who signs: head of airside operations, aviation security manager, accountable manager, head of engineering and systems.
40 to 50
UK airports handling scheduled passenger services; the wider aerodrome layer is excluded from this count
Commercial ports and terminals
Wide perimeters, high value cargo and a security regime that already forces a written plan and a named accountable officer. That combination makes the buying role easy to find and the conversation easy to start.
Who signs: port director, the designated port facility security officer, head of operations, and at group owned ports the security lead sitting above several sites.
100 to 130
UK commercial ports and terminals handling freight, including the multi site groups that own several of them
Stadiums, arenas and major event venues
The layer most likely to be missed by anyone buying a list, because these buyers are registered as clubs, venue operating companies, promoters and racecourse operators rather than as security buyers. The season and the fixture list also give this segment a buying window the others do not have.
Who signs: safety officer, head of safety and security, operations director at the venue or the venue group, and the event security lead for the promoter.
100 to 150
UK venues that regularly seat ten thousand or more, including football grounds, arenas, cricket grounds and racecourses
Licensed nuclear sites
Small by count and slow by design. Approval cycles here are long and heavily documented, which punishes a late start and rewards being known years before a requirement is written.
Who signs: site security controller, head of security for the operating company, and the supply chain lead who runs the qualification process.
30 to 40
sites in the UK holding a nuclear site license, across generation, fuel, defence and decommissioning
Defence primes and tier one integrators
Not an end customer so much as a route to one. A prime that has already won the platform needs an effector or a sensor to drop into it, and that decision is made by a capability owner rather than by a buyer.
Who signs: capability lead, head of uncrewed systems, business development director for land or air, and the supply chain manager who onboards new suppliers.
Roughly 40 to 60 companies
UK based primes and integrators bidding platform level defence work; this layer sits in no single public register and is read from published contract awards

Where the openings are

1
A framework selects for who is already buying, not for who has the problem. The seven groups above come to roughly 475 to 620 individual UK organizations and sites. A framework, a prime relationship or a stand at a trade show reaches whichever slice of that happens to be mid procurement this quarter. The rest is not unqualified. It simply is not looking yet, and it will be, one incident at a time.
2
Venues are the layer lists routinely miss. A club, an arena operating company, a racecourse and a promoter are registered as leisure and entertainment businesses, so anyone buying an off the shelf list of UK security buyers reaches the guarding firms and never sees the venue. Working that group properly takes identification rather than purchase, which is exactly why it stays open.
3
The buyer here is three people, not one. A security lead specifies, an operations lead lives with the disruption, and a commercial or category function signs. Reaching one of the three is how a good system stalls for a year. A channel built on named roles can reach all three inside the same account in the same month, which is a different exercise to answering a tender.
4
Detection, effectors and command software do not travel through the same door. In the UK the authority to disrupt a signal sits with a much narrower set of bodies than the authority to detect one, so detection and command reach the whole page above while effectors reach a subset of it. Treating that as three audiences rather than one product line changes who is worth contacting first.
Built from public sources: published counts of UK police and specialist forces, prison establishments, airports carrying scheduled passenger services, commercial freight ports, licensed nuclear sites and major venues, together with published defence contract awards, current to August 2026. Counts are banded deliberately. The prime and integrator layer is enumerated in no single public register and is read from award history, so it describes scale rather than a finished list. It describes the market rather than your business, and there is nothing to buy at the end of it.
