TM44 Reforms – Regulations Could Be Evolving

With the UK government ramping up efforts to meet Net Zero targets, businesses must prepare for tightening regulations and TM44 air conditioning inspections are firmly in the spotlight.

What Are TM44 Inspections?

TM44 inspections are mandatory assessments of air conditioning systems with a combined cooling capacity of 12kW or more, as required by the Energy Performance of Buildings Regulations (EPBR). These inspections must be conducted every five years and are designed to ensure systems are operating efficiently, safely, and in an environmentally responsible manner.

The aim is not simply to tick a compliance box, a properly conducted TM44 inspection can highlight areas for improvement that reduce energy consumption and running costs, while also extending equipment lifespan.

Why TM44 Compliance Matters More Than Ever

Historically, compliance with TM44 regulations has been patchy. Many commercial buildings are operating without a valid inspection report, often due to a lack of awareness or low perceived risk. Current fines are set at £300 per non-compliant building, with an added £200 penalty for failing to provide documentation when requested, have proven insufficient in driving full compliance.

But that’s about to change. TM44 reforms could be coming around the corner.

The government recently completed a public consultation (closed February 2025) proposing sweeping changes to the way TM44 inspections are regulated and enforced. These reforms are part of the broader Energy Act 2023 and reflect a more assertive approach to energy efficiency in the built environment. Air conditioning inspections could be changing very soon.

Key TM44 Reforms on the Horizon

Here’s what your business needs to be aware of:

• Increased penalties: The fine for non-compliance is proposed to rise to £800 per building, with an additional £200 if a valid report isn’t produced within 7 days of notice.
• Stricter enforcement: Expect more active involvement from Trading Standards and other regulatory bodies, with fewer warnings and more direct penalties.
• Centralised register: A more transparent, digital reporting system will allow regulators (and potentially the public) to view inspection status and ensure consistency across sectors.
• Enhanced inspection value: Updated formats and recommendations will aim to deliver clearer, actionable advice for building operators.

These changes are still under review, but momentum is building, and implementation is expected sooner rather than later. The message is clear: businesses must treat TM44 as a central part of their energy and compliance strategy.

Preparing for the New Compliance Landscape

Even though legislative changes are still pending, businesses should act now, as with all areas of building compliance. Here’s how to stay ahead:

• Audit your current compliance status: Determine whether your existing TM44 report is still valid and whether it accurately reflects your current systems.
• Schedule your next inspection early: Don’t wait until enforcement tightens. Being proactive puts you in control and allows time to implement any recommendations gradually.
• Use inspections as an opportunity: Engage with assessors who can not only carry out the inspection, but also advise on ways to reduce energy use and operating costs.
• Plan for lifecycle management: Integrate TM44 checks into a wider facilities management and sustainability plan to keep your operations efficient and audit-ready.

Final Thoughts

As the UK’s carbon commitments intensify, regulations like TM44 are evolving from technical obligations into strategic priorities. Inspections are becoming more transparent, penalties are increasing, and expectations are higher.

But with that comes opportunity. A well-managed approach to TM44 can unlock energy savings, boost ESG credentials, and strengthen operational resilience, all while keeping your business compliant.

If you’re unsure about your current TM44 status or need guidance on preparing for the coming changes, now is the time to seek expert advice. The cost of inaction is rising, but with the right approach, compliance can become a competitive advantage.
