What Green Zone Surveys does
Green Zone Surveys (UK) Ltd is a private building compliance and energy assessment firm headquartered in Newcastle upon Tyne, with a secondary office in Ormskirk, operating across the UK and Ireland. Founded in 2010, the company delivers TM44 air conditioning inspections, Energy Performance Certificates (EPCs), ESOS energy audits, heat mapping, and related compliance services through an in-house team of 11+ accredited assessors. Its client base spans hospitality, higher education, automotive, life sciences, and industrial services, with named engagements including Village Hotels, Cox Automotive, Glasgow Caledonian University, and ICON plc, and a cumulative footprint of thousands of sites assessed.
The firm operates a project-based services model, charging per-site assessment fees rather than recurring subscriptions, and has extended its offering through two notable additions: the GreenAudit in-house energy audit software platform (launched December 2023) and a Commercial Building Drone Footage service. In December 2024, Green Zone Surveys acquired Enviroduct, adding asbestos surveying, fire risk assessment, and HVAC ductwork compliance to its capabilities. The firm holds accreditations from the Energy Institute, ABBE, Elmhurst Energy, and BESA, supporting positioning across UK regulatory compliance regimes, and is positioning for ESOS Phase 3 demand. In October 2025 it received a strategic investment from Vadella to fund further growth, alongside the appointment of a Finance Director.
