This list ranks the 50 largest by number of employees on LinkedIn, led by Foster + Partners, Automotive Market and 10N Collective. Their median headcount is 350. Half of them were founded in 1980 or later. The most common headquarters are London (35), Lichfield (2) and Manchester (2).

These architecture and planning companies in England are mostly large, established firms, with a focus on sustainable urbanism and innovative design. Many of them, like Foster + Partners, ZHA, and Grimshaw, are global practices with international teams and worldwide offices. RIBA stands out as a global professional membership body dedicated to creating better buildings and sustainable environments.

A clear pattern among these companies is their strong concentration in London, with nearly all major firms headquartered in the capital. While most are well-established, such as tp bennett, founded in 1921, and AHR, founded in 1835, there are also newer entrants like 10N Collective, founded in 2025, indicating a mix of heritage and emerging practices in the sector.

## 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.
