Air Conditioning Inspections

A new requirement for the inspection of air conditioning systems has been set by the Energy Performance of Buildings Directive (EPBD). The requirement is designed to enhance the efficiency of air conditioning systems across the UK, which – in turn – will create savings efficiencies for building owners. Hilsdon Holmes has the expertise to ensure that you meet these regulations successfully.

What are the Regulations Governing Air Conditioning Inspections?

Since January 2009 all Air Conditioning systems over 250kW require a first inspection in order to comply with regulations.

Since January 2011 all Air Conditioning systems over 12kW require a first inspection in order to comply with regulations.

These inspections need to be carried out every 5 years, and the regulations apply to Air Conditioning installations in commercial, residential or public buildings.

As a result of the inspection, a report (AC-Report) and a certificate (AC-Cert) must then be lodged with the landmark Registry. Non-compliance can now result in hefty fines, so it’s important to schedule in your Air Conditioning Inspection as part of your building schedule.
