Need the full list with verified decision-maker contacts? Book a meeting.
The largest sub-industry is other research and experimental development on natural sciences and engineering with 5,964 companies, which is where most research & development outbound in the UK ends up pointed. The tail below it is usually less contested and worth a separate sequence.
Geographically it concentrates in London (3,185 companies), followed by Cambridge, Oxford, Edinburgh. If your reps work by territory, that split is the fastest way to divide the list.
By headcount, 1,659 are micro companies of 1–9 people and 159 sit in the 10–249 range — usually the sweet spot for outbound, since they are large enough to have a budget holder and small enough that the decision maker answers.
