Air Conditioning TM44 Inspections in the UK
If your building uses air-conditioning, you may be legally required to have a TM44 inspection. TM44 surveys ensure your systems are running efficiently, safely and in line with the UK’s Energy Performance of Buildings Regulations.
What Does TM44 Mean?
TM44 refers to the official CIBSE guidance used by accredited energy assessors to carry out air-conditioning inspections. The regulation applies to any commercial or domestic building with a combined cooling capacity of 12kW or more.
Is a TM44 Survey a Legal Requirement?
Yes. UK law requires qualifying systems to be inspected every five years. A valid inspection includes:
· A TM44 report
· An advisory report with energy-efficiency recommendations
· Details of system performance and maintenance issues
Who Enforces TM44 Regulations?
TM44 compliance is enforced by local Trading Standards departments. They can request your latest inspection certificate at any time and issue financial penalties if you fail to produce it.
Which Premises Need a TM44 Inspection?
TM44 applies to almost all non-domestic buildings, including:
· Offices and commercial premises
· Retail shops and shopping centres
· Restaurants, hotels and leisure facilities
· Warehouses and industrial units
· Healthcare and educational buildings
· Managed and multi-tenanted properties
If your property has several small split systems, their cooling capacities are added together – meaning many sites exceed the 12kW threshold.
Benefits of a TM44 Survey
A professional TM44 inspection helps your business:
· Reduce energy costs by identifying inefficient operation
· Improve system reliability and reduce downtime
· Extend equipment life through better maintenance strategies
· Enhance comfort for staff, customers and tenants
· Demonstrate legal compliance and reduce audit risk
· Support ESG, sustainability and carbon-reduction goals
What Happens If You Don’t Have a TM44?
Non-compliance can lead to:
· Fixed penalties of £300 per system, repeatable
· Requests for evidence from Trading Standards
· Increased running costs due to energy waste
· Decreased confidence from tenants or stakeholders
