What HEYDA LTD does

HEYDA LTD is a UK-based independent acoustic consultancy registered in England and Wales (Company Number 15368648) with a registered office at 15 Jefferson Close, London, W13 9XJ. The firm was founded by Directors James Williams and Sam Laws, who together bring over 30 years of combined experience from senior technical-lead roles at Europe's Largest Engineering Consultancy. Williams has personally completed over 50 education projects and extensive BS 4142 industrial noise assessments, while Laws is described as a seasoned acoustic engineering professional. The company operates from London and serves clients across the United Kingdom.

The consultancy offers three core service lines: Building Acoustics (design, measurement, specification, simulation, and testing for residential, commercial, education, healthcare, data centre, music studio, leisure, hospitality, and public-sector buildings), Environmental Acoustics (noise surveys, acoustic modelling using CadnaA and SoundPlan, BS 4142 and ProPG impact assessments, and planning support), and Vibration Services (industrial, structural, construction, and transportation infrastructure analysis). A subscription-based Construction Noise, Vibration and Dust Monitoring product uses Sonitus and AVA remote monitoring equipment with real-time data via the Sonitus Cloud portal, requiring a six-month minimum term. The firm also publishes an Information Centre blog and a Top 5 Acoustic Ceiling Providers UK guide as content-marketing assets.

The business model is professional-services consultancy revenue. Standard hourly work is billed at £80 per hour — positioned competitively against Director-level benchmarks of £110-£150+ elsewhere — with travel and accommodation charged additionally. Defined-scope projects are quoted on a fixed-fee lump sum basis, and sector-specific indicative budgets are published for noise impact assessments, building acoustics design, and acoustic ceiling design. The go-to-market is direct-to-client inside sales: enquiries arrive via website contact form, phone (0800 099 6033), and email ([email protected]), and a Director personally reviews each quote to prepare scope of works and fee proposals. The current customer base is diversified across construction, architecture, project management, events, and automotive clients including SDC, RH Partnership, 5DM Group, McLaren, Auburn Group, Blue Copas, Fusion PM, Axis Mason, and LSL Partners. The firm displays industry body credentials (1ftp Business Member, SIPP, Acclaim, Samson) and is currently operating with no disclosed external investors or parent company.
