What Temple Group does
Temple Group is a UK-based environment and sustainability consultancy founded in 1997 by Mark Southwood. The firm delivered integrated environmental, planning, and sustainability advisory services — including impact assessments, biodiversity advisory, ecology surveys, arboriculture, environmental surveys, noise/vibration/air quality assessments, and socio-economic and health services — to government, infrastructure, and real estate clients. Marquee engagements included the £800m Jersey Hospital planning strategy and application, Barking Riverside ecology services, The River Thames Scheme, High Speed 2, and East West Rail. The firm was B-corp certified and operated as a portfolio of multi-disciplinary advisory practices rather than a software or platform business, with no proprietary technology disclosed in the source material.
Temple generated revenue through bespoke professional services engagements, typically on a project basis for public-sector and large enterprise clients. Pricing was not publicly disclosed and operates as contract-by-contract consultancy work rather than subscription or productized offerings. Client acquisition occurred primarily through reputation, referrals, and direct engagement rather than through active marketing channels. The firm operated from a UK domicile, serving European markets.
On 12 May 2025, Ramboll — a global engineering, architecture, and consultancy firm with 18,000 experts across 35 countries and a foundation-owned ownership structure — announced the acquisition of Temple. The 150-person team joined Ramboll's UK Environment & Health division (then ~300 employees), with Temple CEO Mark Skelton joining Ramboll's global E&H leadership team and founder Mark Southwood stepping down as Chair after a three-month integration support period. As an independent entity, Temple ceased to exist following completion of the integration later in 2025.
