TM44 Air Conditioning Inspections (ACI)
TM44 air conditioning inspections are a legal requirement for commercial buildings in the UK with systems over 12kW. If you’re unsure whether your building requires a TM44 inspection, when it’s due, or how to obtain a valid certificate quickly, understanding the requirements is essential for staying compliant and avoiding penalties.
Under the Energy Performance of Buildings (England and Wales) Regulations, TM44 inspections must be carried out in line with UK Government guidance, ensuring air conditioning systems are operating efficiently and appropriately sized for the building.
A valid TM44 inspection certificate must be in place and renewed every five years, and inspections must be conducted by accredited TM44 assessors.
CCA Environmental provides professional TM44 air conditioning inspections for commercial buildings, supporting landlords, managing agents, facilities teams and occupiers with clear compliance, practical reporting and expert guidance.
Our inspections help you meet statutory requirements, avoid enforcement action and identify realistic opportunities to improve system efficiency, reduce energy consumption and lower running costs.

Why TM44 Air Conditioning Inspections Matter
TM44 inspections are not just a compliance exercise. They play an important role in identifying inefficient systems, oversized plants, poor controls and maintenance issues that increase energy use and costs.
TM44 ACI reports are often requested during lease events, audits and regulatory checks, and can also support wider energy performance, EPC and MEES compliance strategies.
TM44 air conditioning inspections are classified by system complexity:
-
- Level 3 TM44 inspections apply to simpler systems such as split and multi-split air-conditioning serving limited zones.
- Level 4 TM44 inspections are required for more complex installations, including VRF/VRV systems, chilled water systems, central plant and buildings with multiple air-handling units and advanced controls.
Both TM44 inspection levels assess system efficiency, condition, controls and maintenance practices, and identify opportunities to reduce energy use and carbon emissions. Level 4 inspections involve a more detailed evaluation of how the air-conditioning system interacts with the building, occupancy patterns and controls.
CCA Environmental are fully qualified to deliver TM44 air conditioning inspections and reports for both Level 3 and Level 4 systems. Our inspections are compliant, practical and commercially focused, helping you meet statutory obligations while identifying realistic energy-saving improvements.
If you need guidance on your TM44 inspection for a commercial building, our team is happy to advise.
TM44 Air Conditioning Inspection Process
A TM44 inspection involves a structured assessment of your air conditioning system to ensure compliance, energy efficiency and correct system sizing in line with UK regulations.
- Initial Enquiry & Fixed Fee: We confirm the required TM44 inspection level based on system size, layout and complexity, and provide a clear, fixed fee with no hidden costs.
- On-Site Air Conditioning Inspection: Our accredited assessor attends site to carry out the inspection in line with CIBSE TM44 guidance. This includes system sampling, review of plant condition, controls, maintenance records and system sizing against actual building use.
- Assessment & Recommendations: System efficiency and operational performance are assessed, with clear, practical recommendations to improve efficiency, reduce energy consumption and support ongoing compliance.
- TM44 Inspection Report Issued: A fully compliant TM44 inspection report and certificate are prepared and typically issued within 2 working days of the site visit, helping you meet audit, lease and regulatory requirements.

How We Can Help With TM44 Compliance
Responsibility for TM44 compliance typically falls on building owners, landlords, managing agents and occupiers responsible for the air conditioning system. Ensuring a valid TM44 certificate is in place every five years is a legal obligation, and failure to comply can result in enforcement action.
CCA Environmental supports landlords, managing agents and occupiers with fully compliant TM44 air conditioning inspections across the UK. We help you meet legal requirements, avoid compliance risks and identify opportunities to improve system performance and energy efficiency.
TM44 air conditioning inspections are mandatory every five years for qualifying systems over 12kW.
