Who Is Responsible For TM44 Inspection Compliance?

Who Is Responsible For TM44 Inspection Compliance?

TM44 inspections evaluate the performance of air conditioning systems. They offer guidance on potential improvements and confirm that systems run safely and as intended.

Regular inspections satisfy TM44 legal obligations. They also help lower energy bills and support a more environmentally responsible way of operating.

Knowing who is responsible for TM44 inspection compliance is vital. It helps maintain energy efficiency, meet legal duties, and avoid possible penalties.


Who is Responsible for TM44 Compliance and Inspections?

  • The building owner, manager, or landlord who oversees the air conditioning system holds responsibility for TM44 compliance.
  • Tenants or occupants who simply control the thermostat are not responsible for TM44 compliance.
  • Accredited energy assessors, such as Smart Energy Projects, must perform TM44 inspections to satisfy legal requirements.

Who Is Responsible For TM44?

In most cases, the building owner or facilities manager holds TM44 compliance responsibility. This falls on whoever oversees the air conditioning system's operation.

Multi-Tenant Buildings

In buildings with multiple tenants — such as apartment blocks or shared office spaces — the landlord or property management company takes responsibility. They oversee the central system. As a result, they must arrange regular inspections by accredited energy assessors. They must also keep thorough, accessible inspection records to demonstrate compliance.

What About Tenants?

Tenants, employees, or other occupants with thermostat access are not liable for TM44 compliance. This applies whether the property is residential or commercial. Many people mistakenly assume that adjusting the thermostat makes them responsible for the entire system. This is not the case.


Are TM44 Inspections Mandatory?

Yes, TM44 inspections are a legal requirement. Under the Energy Performance of Buildings (Certificates and Inspections) Regulations 2007, any air conditioning system exceeding 12kW must undergo an inspection every five years.

These requirements encourage businesses to prioritise energy efficiency. They also set specific timeframes for the initial inspection, based on installation date and system capacity.

An accredited energy assessor, such as Smart Energy Projects, must conduct all TM44 energy inspections.


Consequences Of Non-Compliance With TM44 Regulations

Failing to meet TM44 inspection requirements leads to significant financial penalties.

Fines for Missing Inspections

Building owners, managers, or landlords who fail to arrange a TM44 inspection face fines. These accumulate on a weekly basis until they produce a valid report.

Fines for Missing Reports

A separate £200 fine applies when someone fails to provide an outstanding report within seven days of a request.

Beyond the Financial Impact

Non-compliance carries consequences beyond financial penalties. It results in higher energy costs and reduced system efficiency. It also means missing opportunities to make meaningful operational improvements.
