What Sonar Engagement Ltd does

Sonar Engagement Ltd is a privately held UK consultancy, founded by Paul Valentine in 2012 and headquartered in Northampton, that provides community engagement, social value, stakeholder management and public consultation services to infrastructure contractors, local authorities, NHS bodies and related public sector clients. The firm's core product is the trademarked CWaNA™ (Community Wants and Needs Assessment) methodology — a seven-stage structured framework grounded in the SARA model used in UK policing — which it uses to produce auditable evidence trails aligned to PPN 002, the Social Value Model 2025 and NHS Evergreen Assessment requirements. Service lines include stakeholder mapping and PLO deployment on live schemes, social value gap analysis and bid writing support, local needs assessments for councils and Pride in Place Neighbourhood Boards, CPD-accredited training and a two-tier CWaNA™ Certification programme, plus a Customer Road Audits product that delivers filmed, same-day feedback on highways and utility schemes.

The business operates on a sales-led, direct engagement model with no automated funnels: conversations are run by the founder, the Healthcare Social Value Lead or the Social Value Director depending on client need. Revenue is generated through professional services fees (consulting engagements, PLO day-rates, bespoke in-house training), training and certification programmes (individual online, group, and bespoke in-house), and per-engagement road audit fees. Customers include National Highways, Network Rail, Kier, Balfour Beatty, Tarmac, Carnell Group, AmcoGiffen, QTS Group, Walter Lilly and Forkers/Severn Trent Water, alongside NHS suppliers and local authority Neighbourhood Boards. The company is privately held with no disclosed external investors, has no disclosed revenue, and operates across England, Scotland and Wales with a team in the 11-50 range.
