Over-cooling and poor control strategies
Inefficient operation
Opportunities to reduce running costs and carbon impact
What is it?
A TM44 inspection is a mandatory assessment of air conditioning systems with a combined cooling capacity of over 12kW. The inspection reviews the efficiency of your system providing recommendations to reduce energy use and carbon emissions.
Inspections must be carried out by an accredited TM44 energy assessor
The report must be lodged on the official government register
wHY DO YOU NEED AN INSPECTION?
TM44 air conditioning inspections are a legal requirement in the UK under the Energy Performance of Buildings (England and Wales) Regulations 2012 and, in Scotland, the Energy Performance of Buildings (Scotland) Regulations 2008.
These regulations implement the Energy Performance of Buildings Directive (EPBD), which aims to improve building energy efficiency and reduce carbon emissions across Europe.
