# 50 leading professional services firms in Scotland

Tamtam tracks 112 professional services firms headquartered in Scotland. This list ranks the 50 largest by number of employees on LinkedIn, led by Wood Mackenzie, Search Recruitment Group and Search. Their median headcount is 480. Half of them were founded in 1995 or later. The most common headquarters are Edinburgh (16), Glasgow (13) and Aberdeen (10).

These Scottish professional services companies are mostly large firms, many of them with an international reach. They span a range of sectors, from information services and staffing to legal and accounting. For example, Wood Mackenzie provides data and consultancy for renewables and natural resources, while Search Recruitment Group offers global recruitment solutions. Brodies LLP specializes in legal advice, and Johnston Carmichael provides accounting and business advisory services.

A notable pattern among these companies is the strong presence of firms in Aberdeen, particularly those focused on the energy sector. CAN Group is a global provider of asset integrity services for energy, and PD&MS Group offers EPCC expertise for onshore and offshore energy projects. This concentration highlights Aberdeen's role as a key hub for energy-related professional services.

## 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.
