TM44 Certification: Why It Matters and How Much the Inspection Costs?
How do you obtain this certificate? Is it essential, and what costs should you expect? This blog addresses all these questions and offers additional insights.
In today's energy-conscious world, maintaining an energy-efficient environment is not only good for the planet but also legally required in many cases. If your building has air conditioning systems with a combined cooling output exceeding 12 kW, you are legally required to undergo a TM44 inspection. This inspection results in a TM44 certificate, a vital compliance document in the UK and several other regions.
What Is a TM44 Certificate?
A TM44 certificate is an official document issued following an energy inspection of air conditioning systems, conducted by the guidance outlined in the TM44 regulations. These regulations were introduced by the Chartered Institution of Building Services Engineers (CIBSE) and support compliance with the UKs Energy Performance of Buildings Directive (EPBD).
The resulting certificate proves that the inspection has been completed and includes:
Details of the inspected systems
Observations on system performance
Maintenance issues and improvement advice
Compliance status and inspection date
Is a TM44 Certificate Essential?
