# Simpson Associates
Simpson Associates is a structural and civil engineering consultancy based in London with additional offices in Henley on Thames and Gloucester. Established in 1969, the firm has built a distinguished reputation delivering high-quality engineering solutions across the UK.
The practice serves commercial enterprises, public sector organisations and domestic clients who require expert engineering guidance for their projects. Their client base typically includes property developers, construction companies and institutional bodies needing structural assessment or infrastructure planning.
What distinguishes Simpson Associates is their collaborative, hands-on approach. Rather than providing generic solutions, they focus on practical, commercially-minded engineering that maximises site development potential. Partners remain actively involved throughout projects, from initial conception through to completion, ensuring bespoke solutions tailored to each client's specific requirements.
Their structural engineering division offers comprehensive services including structural design, detailed analysis work and forensic investigation for buildings and structures. The civil engineering team specialises in infrastructure development, environmental assessment, hydrology studies and transport planning—disciplines that work together to unlock development opportunities.
The firm's longevity since 1969 reflects both technical competence and client satisfaction. Their multi-office presence enables UK-wide service delivery whilst maintaining the personalised attention associated with a specialist consultancy rather than a faceless corporate entity.
