# Top 49 consulting firms in Scotland

Tamtam tracks 49 consulting firms headquartered in Scotland. This list ranks all of them by number of employees on LinkedIn, led by Wood Mackenzie, AAB and SRUC. Their median headcount is 63. Half of them were founded in 2010 or later. The most common headquarters are Edinburgh (25), Aberdeen (9) and Glasgow (5).

This list of Scottish companies includes a significant number of firms specializing in professional services and energy. Many of these are well-established mid-sized firms. For instance, Wood Mackenzie provides data and consultancy for renewables and natural resources, while AAB offers audit, accounting, and HR services. Johnston Carmichael is an independent firm of chartered accountants, and SRUC is an educational institution with consultancy in land-based industries. PD&MS Group and CAN Group provide engineering and asset integrity services for the energy sector.

A notable pattern among these companies is the concentration of headquarters in Aberdeen, particularly among those involved in oil and gas and related engineering services. Glasgow and Edinburgh also host several companies, including IES Ltd. which specializes in sustainable building design software, and Fairhurst, a civil engineering firm. This distribution highlights a strong regional focus within Scotland's consulting and professional services landscape.

## 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.
