Reachable Buyer Map

Prepared for Canberk Incekara · OCS · August 2026
This map counts the United Kingdom, where the group is headquartered. In facilities services, first contact usually happens inside a tender that is already running, on a framework already in place, or with someone who already knows the name. That reaches the part of the market that is buying this year and is silent about the rest. This map is the rest. Six of the sectors OCS names as its own, who signs inside each one, and roughly how many organizations sit there.
Health and care providers
The estate with the least tolerance for a service failure and the longest procurement path to match. Soft services and hard services are frequently bought by two different people here, which is an argument for two conversations rather than one bid.
Who signs: director of estates and facilities, head of soft FM, chief operating officer, procurement lead.
200 to 220
NHS trusts in England, alongside roughly 500 to 600 independent hospital and clinic sites
Government and the public estate
Councils run the widest mix of buildings of any buyer in the country, from offices and schools to depots and leisure sites, and they publish their contract expiry dates. Central departments and their arms length bodies sit above this and are reached one by one rather than as a list.
Who signs: head of corporate landlord or property services, category manager for FM, director of place, strategic procurement lead.
380 to 400
UK councils, plus central departments and their arms length bodies, which are described here rather than counted
Data centers and critical environments
Small by count and the fastest growing line in the market. Uptime is the only metric that matters, so the buyer cares far more about who holds the engineering ticket than about the price of the cleaning schedule. Self delivered technical services is the argument that lands here.
Who signs: data center operations director, head of critical environments, facilities manager, group procurement.
450 to 550
UK data center sites, counted as sites rather than operators, so a group with several halls appears more than once
Aviation, rail and transport hubs
Public facing services sit next to security and technical work in the same building, and the same operator is rarely trusted with both. It is also the segment where a passenger experience failure becomes a public one within the hour, which shortens the conversation about quality.
Who signs: terminal operations director, head of passenger services, station estates manager, head of procurement.
40 to 50
UK airports with scheduled commercial service, alongside around 25 train operating companies
Education estates
The largest segment by count and the one most often reached late. Academy trusts buy across many buildings at once, which makes a single relationship worth several sites, and their estates leads turn over often enough that the roster reopens on a regular basis.
Who signs: trust estates director, chief operating officer, director of estates at a university, head of campus services.
1,000 to 1,300
multi academy trusts in England, alongside roughly 160 to 180 UK universities and higher education institutions
Manufacturing, distribution and logistics
Here facilities work is judged as production time rather than as service quality, so the case is made in output and compliance language. Sites are frequently added faster than the FM contract is renegotiated, which is a reason these accounts reopen between formal tender cycles.
Who signs: site or plant director, head of manufacturing operations, regional facilities manager, supply chain and property lead.
900 to 1,200
UK manufacturers at 250 people or more, alongside roughly 400 to 600 transport and storage operators at that size

Where the openings are

1
The tiles above, counting the secondary lines, come to 4,055 to 5,125 UK organizations. A tender process reaches whichever slice of that has already decided to go to market this year. The rest are not unqualified, they are simply between cycles, and between cycles is the only moment a new supplier gets heard without a price war attached.
2
Education is the biggest single count and the least contested. Roughly 1,000 to 1,300 multi academy trusts, each with someone who owns the estate across many buildings, against 200 to 220 NHS trusts that the whole market already chases. Same buying role, a tenth of the competition for attention.
3
The buyer here is a role, not an organization. Estates director, head of facilities, category manager for FM. Those seats turn over, and a new one almost always reviews the incumbent inside the first year. A channel built on named roles catches that moment. A channel built on tender notices hears about it after the specification is written.
4
Six sectors is not one audience. What a data center operations director needs to hear has almost nothing in common with what a trust estates director needs to hear, and both are different again from a plant director. One outbound voice tends to flatten all three into a capability list. Six named audiences is a different reach problem, and a solvable one.
Built from public market data covering the United Kingdom, counts banded deliberately. Registers count organizations rather than buildings, so a body with many sites appears once, and the data center tile is the exception because it is counted as sites. Sector boundaries differ between sources, and the independent healthcare, data center and academy trust figures come from published sector reporting rather than one official list. It describes the market rather than your business, and there is nothing to buy at the end of it.
