Mandatory TM44 Air Conditioning Inspection: ensure compliance & improve efficiency
Ensure your client properties meet their legal obligations under UK Energy Performance of Buildings Directive (EPBD) regulations with a compliant TM44 Air Conditioning Inspection. If the buildings you manage have air conditioning systems with a total effective rated cooling output over 12kW, a TM44 inspection by an accredited assessor is mandatory every five years. These assessments evaluate the efficiency of your systems and provide valuable recommendations for improvement.
Based in Ripley, we provide accredited TM44 inspection services for facilities management companies and building operators across Derbyshire and surrounding areas. Our goal is to help you achieve compliance while identifying potential energy savings and operational improvements for your air conditioning systems.
Understanding your legal obligation
The requirement for TM44 inspection stems from the EPBD regulations and applies to any single or combined air conditioning system with a total cooling capacity exceeding 12kW under one operator's control.
As a facilities management company, you may manage TM44 compliance on behalf of multiple clients across diverse building types. Understanding who bears ultimate responsibility - your FM contract, the building owner, or the occupier - is essential to ensure proper compliance management and avoid gaps that could expose your clients to penalties.
Inspections must be repeated every five years, and failure to produce a valid report upon request can lead to financial penalties for the responsible party.
Common TM44 challenges for facilities management
Facilities management companies face specific air conditioning compliance challenges:
- Multi-client portfolio management requires tracking TM44 compliance across numerous buildings, each with different inspection due dates, system types, and client requirements. Without robust systems to monitor renewal schedules, it's easy for individual sites to fall out of compliance, creating liability for your clients and reputational risk for your FM business.
- Diverse building types mean your team manages everything from offices and retail to healthcare, education, and industrial facilities - each with different operational constraints, access requirements, and air conditioning configurations. TM44 assessors need to understand these varied environments and adapt inspection approaches accordingly.
- Coordinating with multiple stakeholders adds complexity to scheduling inspections. Each site may require coordination with building occupiers, client representatives, and your own maintenance teams, all while minimising disruption to business operations.
- Client operational needs vary significantly. A retail client may require inspections outside trading hours, a healthcare facility needs zero disruption to patient care, and an office tenant may only permit access during specific maintenance windows. Managing these constraints across your portfolio requires flexibility and careful planning.
- Compliance deadlines don't align with maintenance schedules, meaning TM44 inspections need to be tracked separately from your routine planned preventive maintenance programmes. Sites can have valid maintenance contracts but still fall out of TM44 compliance if inspections aren't separately scheduled.
- Documentation and audit trails must be maintained for each client, with certificates properly lodged and records accessible for audits, lease reviews, or property transactions. Managing this paperwork across a large portfolio requires robust systems.
The TM44 inspection process
Our accredited assessors conduct thorough on-site inspections with minimal disruption to building operations.
The process involves reviewing relevant system documentation (like maintenance logs and manuals), visually inspecting accessible plant and equipment (including indoor and outdoor units and controls), assessing system sizing against actual cooling loads, and evaluating current operation and maintenance regimes against best practices.
For facilities management companies, we provide centralised coordination across your client portfolio, consistent reporting standards, and clear communication with your teams to integrate inspections smoothly into your existing maintenance programmes.
Clear reports & actionable advice
Following the inspection, you will receive a comprehensive TM44 report lodged on the official government register. This report details the assessment findings and provides clear, practical recommendations for improving energy efficiency.
Advice may cover operational adjustments, maintenance enhancements to improve system performance, or potential system upgrades, often with estimated energy and cost savings. For facilities managers, recommendations integrate with your existing maintenance programmes and provide evidence-based priorities for discussing improvements with clients.
Benefits beyond compliance
While TM44 inspections are mandatory, they offer significant benefits for facilities management companies and their clients. The impartial report identifies genuine opportunities to reduce energy consumption and lower operational costs across your managed portfolio.
Implementing recommendations can also lead to a reduced carbon footprint for your clients, improved system reliability and reduced emergency callouts, better building performance supporting tenant satisfaction, and potentially extend the lifespan of equipment through optimised operation and maintenance.
Meet your legal obligations
Stay fully compliant with the UK EPBD air conditioning regulations to avoid potential penalties for your clients and protect your FM company's reputation. Demonstrating robust compliance management across your portfolio positions your business as a professional, reliable partner that protects clients from regulatory risk.
Identify energy and cost savings
Benefit from expert, impartial advice that highlights specific ways to reduce air conditioning energy use across your managed properties. By improving system efficiency, you can demonstrate tangible value to clients through lower operational costs and receive clear estimates of potential financial savings that support contract renewals and service reviews.
Improve system performance
Understand how well current systems are performing and where there's room for improvement across your portfolio. Enhancing maintenance practices and system controls can improve reliability and occupant comfort while ensuring long-term efficiency. Better system performance reduces reactive callouts and demonstrates the value your FM services deliver.
Support your clients' sustainability goals
Reduce carbon footprint across your managed portfolio and help clients align with their environmental responsibility goals. You'll receive practical guidance on sustainable cooling strategies that help buildings operate more efficiently and reduce environmental impact. For FM companies with sustainability commitments or clients with ESG targets, TM44 compliance and efficiency improvements provide measurable progress toward environmental objectives.
