Half of them were founded in 1986 or later. The most common headquarters are Glasgow (11), Edinburgh (9) and Aberdeen (8).

This selection of companies with in-house R&D in Scotland shows a mix of industries, with a significant presence of higher education and industrial manufacturing. Companies like The Weir Group PLC (mining technology) and Howden (air and gas handling products) represent established industrial sectors, while newer firms such as Skyscanner (internet publishing) and IES Ltd. (sustainable building software) highlight technological advancements. Many of these companies are large, well-established organizations, with several founded in the 19th century.

A notable pattern among these companies is their diverse geographical distribution across Scotland. While Edinburgh and Glasgow feature prominently with headquarters for institutions like the University of Strathclyde and Heriot-Watt University, other significant players like Scottish and Southern Electricity Networks are based in Perth, and Sparrows Group operates from Aberdeen, indicating a broad spread of R&D activities.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
