DAA Group

What DAA Group does

DAA Group is an independent UK acoustic consultancy and building compliance engineering firm founded around 1994 in Hampshire. The company delivers a consolidated portfolio of testing, assessment, and certification services required under UK Building Regulations Parts E (sound insulation), F (ventilation), G (water efficiency), and L (air tightness and energy performance), alongside SAP calculations, EPC certificates, energy statements, and BS4142/BS8233 noise impact assessments across residential, commercial, industrial, hospitality, gym, and entertainment verticals. Technology is centered on UKAS-calibrated physical measurement equipment operated by accredited engineers following ATTMA TSL1 standards for air tightness and BPEC/Optimum Energy protocols for ventilation and heat pump commissioning — the company does not operate a software platform and does not disclose any proprietary AI/ML capabilities.

The firm operates a sales-led, project-based professional services model with revenue generated per test, per unit, or per site. Pricing is transparently published for portions of the portfolio (SAP calculations from £70-£100 per unit, water efficiency from £20 per unit), with project quotes for sound and air tightness testing that include site fees plus per-test fees and volume discounts. The customer base is broad and horizontal: developers, contractors, architects, housing associations, local authorities, commercial operators, and individual homeowners. The firm name-publishes a small set of reference customers (Fireaway, Muscle Works, Kokoro, Fan Services Ltd) but these appear to be illustrative brand mentions rather than enterprise anchors.

DAA Group is a privately held, founder-owned company with no disclosed parent, no external funding rounds, no subsidiaries, and no headcount growth signals. Distribution is built on six regional offices (London, Birmingham, Bristol, Hatfield, Aldershot, South Benfleet) enabling nationwide on-site service delivery, supported by a digital presence (passmysoundtest.co.uk, social media channels, SEO) and a phone-led sales motion. The company emphasizes its multi-body accreditation stack (Institute of Acoustics, SITMA, ATTMA, Stroma, BPEC, Optimum Energy, UKAS) and a self-reported high return-client rate as its primary competitive differentiators.
