Accredited TM44 Assessments for Your Business
Our certified inspectors carry out TM44 assessments across the UK, helping businesses meet legal standards while improving system efficiency and performance.
Our TM44 Service
With over 30 years of experience in the heating, ventilation, and air conditioning industry, we deliver TM44 inspections that go beyond compliance. Our team combines technical expertise with real-world insight — helping businesses identify inefficiencies, cut costs, and meet their legal obligations with confidence.
All TM44 inspections are carried out by qualified and accredited commercial energy assessors, certified at Level 3 or Level 4 depending on system complexity.
Level 3 inspections cover simple systems such as split or VRF units.
Level 4 inspections apply to more complex setups involving AHUs and chillers.
Every inspection includes a detailed written report, lodged with the government’s Landmark Registry and valid for five years. Alongside compliance findings, your report will highlight practical steps to boost performance, optimise control settings, and reduce energy waste — often without major capital investment.
We help you achieve compliance and efficiency in one move, making your air conditioning system more cost-effective, sustainable, and future-ready.
