Reachable Buyer Map

Prepared for Eirini Etoimou · Sustainable Mindset · August 2026
From the outside, this practice reads as reputation-led: the book, the lectern, the fellowship, the people who already know the name. That is a real channel and a slow one, because it only reaches organizations that sent someone to look. The companies carrying the most unexamined cost in procurement and operations are precisely the ones that sent nobody. This map is those companies, in the UK. The segments, the seats that sign a diagnostic, and roughly how many sit in each. It describes the market rather than your business, and there is nothing to buy at the end of it.
Large UK employers, 250 people and up
The band where a margin and resilience diagnostic is a funded piece of work with a sponsor rather than a favor. They also carry a mandatory annual energy and carbon disclosure, which puts a dated moment in every year when the numbers are being assembled and the gaps are visible internally.
Who signs: chief operating officer, chief financial officer, procurement or supply chain director, head of sustainability.
8,000 to 8,500
UK private sector businesses at 250 or more employees, roughly one in every 700 companies but nearly half of national turnover
Food and drink manufacturers
The sector where sustainability, procurement and margin are already the same conversation, because input volatility, energy load and waste show up directly in cost of goods. Also the sector most used to being audited, which shortens the argument for an auditable decision framework.
Who signs: operations director, technical director, procurement director, head of responsible sourcing.
7,000 to 12,000
UK food and drink manufacturers, the range reflecting a narrow trade body definition against a wider filing based one
Industrial and engineering mid-market, 50 to 249 people
Big enough to have real exposure in energy, materials and supplier concentration, small enough that one conversation with a managing director settles whether the work happens. Rarely competed for, because most advisory attention goes either to the very large or to the very small.
Who signs: managing director, operations director, head of procurement, finance director.
6,000 to 8,000
UK manufacturing and engineering businesses in that employee band
Logistics, transport and warehousing
The segment where a decarbonization question and a cost question are the same question, and where customers now push disclosure requirements down the chain contractually. That external pressure is what turns an interesting idea into a funded one.
Who signs: operations director, network or fleet director, head of compliance, commercial director.
3,000 to 4,500
UK transport, logistics and warehousing operators at 50 or more employees
Construction and the built environment
Long chains, thin margins and a client base that now writes environmental requirements into tender documents. Being straight about a limit: buying here is project shaped rather than annual, so the useful trigger is a bid or a framework renewal rather than a fiscal year.
Who signs: commercial director, head of pre-construction, procurement lead, head of ESG.
3,000 to 4,500
UK construction and built environment firms at 50 or more employees
Public and regulated buyers
Slow, formal and durable once you are in. Everything here runs through published procurement, which means the route is a framework and a named category officer rather than a relationship, and the same credentials serve many buyers.
Who signs: category manager, head of procurement, sustainability officer, estates director.
800 to 1,000 bodies
UK local authorities, NHS trusts and boards, and higher education institutions taken together
The speaking, teaching and fellowship audience
Your other market, and a separate one. Conference chairs, association education leads, internal learning owners and university partners each own a date and a budget, and that person is almost never the one who buys a diagnostic. Stated plainly: this group appears in no register, which is exactly why it stays underworked by everyone.
Who signs: conference program chair, association education director, head of learning and development, faculty lead.
No public register
reached by name and by event, one at a time; the difficulty is the reason the segment stays open

Where the openings are

1
Your two buyers rarely talk to each other. The head of sustainability wants the work and rarely holds the budget. The finance and procurement seats hold the budget and are usually pitched in a language they did not ask for. Your own framing, cost exposure and auditable return, is aimed squarely at the second one, which means the outreach should be too, and almost nobody does that.
2
The disclosure calendar is a dated trigger, and dated triggers are mechanical. Several thousand large UK companies assemble an energy and carbon statement every year, and the weeks when they are doing it are the weeks the gaps are most obvious internally. Watching several thousand filers for that moment is not a relationship problem, it is a scheduling problem, and it is exactly the kind of thing a machine does and a network cannot.
3
Procurement is the underworked door. Most outreach in this field goes to sustainability titles because they are easy to find. The spend that a diagnostic actually recovers sits with the procurement director, who is measured on cost and almost never approached with a sustainability argument framed as one.
4
This is a distribution gap, not a credibility one. Diagnosing organizations is your discipline and you do not need help with it. What a reputation-led practice rarely has is the machinery that puts you in front of several thousand named operations and procurement leaders who have never heard of you, on a schedule, and tracks what comes back. That is the part we build, and we hand it over when it works.
Built from public market data covering UK business population estimates by size band and sector, published trade body counts and public sector body lists, current to the most recent published year. Counts are banded deliberately. Sector counts move sharply with definition, since a filing based count of food manufacturers is several times a trade body one, and group structures mean reporting entities and businesses are not the same number.
