Walsh

What Walsh does

Walsh is a UK-based structural, civil, and geotechnical engineering consultancy operating under the legal name Walsh Associates Limited. Founded in 1993 and headquartered at The Clove Building, London, with a regional office in Birmingham, the firm employs over 130 staff and serves the UK's largest real estate developers across residential, commercial, public, and PBSA (Purpose-Built Student Accommodation) sectors. Core service lines — Structural Engineering, Civil Engineering, Geotechnical & Geoenvironmental Engineering, and Construction Engineering — are delivered as integrated multi-disciplinary packages rather than siloed disciplines, underpinned by lean design principles that target cost and embodied-carbon reductions. Walsh differentiates through senior-staff engagement on every project, an in-house Embodied Carbon Assessment Tool (ECAT), and a sustainability monitoring toolkit applied across more than 150 measured projects.

The firm's revenue model is professional services fees charged on a project basis, with multi-year contracts typical for major schemes. Pricing is quote-driven and described by the firm as "honest pricing" — fees are positioned as being recouped many times over through savings delivered by lean design (e.g., 14% fewer piles, £2.5m structural steel savings, 53% foundation excavation savings on Coppermaker Square). The go-to-market is enterprise field sales: direct appointments and competitive tendering for major projects with developers such as Unibail-Rodamco-Westfield, Ballymore, Greystar, Galliard Homes, Countryside Partnerships, and Cain International/Vanke, supplemented by thought leadership channels including Walsh Talks events, CPD workshops, white papers, and conference presence.

Walsh is privately held with no disclosed external funding, parent company, or venture capital backing. Notable positions and credentials include B Corp certification (June 2026), Science Based Targets initiative (SBTi) recognition for Net-Zero targets, ICE-accredited Professional Development Scheme, and a stack of industry awards (IStructE Structural Awards 2023, RIBA National Award 2022, Tall Buildings Awards 2024 shortlisting, MMC Awards 2025 double win). Leadership comprises Managing Director Ian Welsh alongside directors Peyrouz Modarres (Sustainability), Jacqui Kantor (Civil Engineering, promoted from Associate Director), Garreth Joyce (Business Development), and Andy Stanford (Civil Engineering and H&S).
