Does your Dorset / Hampshire business require commercial air conditioning system inspections?

Is your commercial air conditioning system operating within UK law?

With a whole host of UK guidelines, directives and government papers regularly being published around commercial air conditioning systems, you may well be confused as to which air conditioning inspections you need. To help bring some clarity to legal obligations around running commercial air conditioning systems, we have reviewed UK guidelines and legislation to produce a simple guide.

In this article, we outline some of the key air conditioning inspections that are designed to help our commercial air conditioning clients in Dorset and Hampshire to reduce operating costs, improve efficiency and limit the environmental impact of their systems.

Which air conditioning inspections do you need to meet UK law?

Before we get into the detail around which inspections you are required to undertake, it’s pertinent to note that it is the EU Energy Performance of Buildings Directive (EPBD) which outlines the required inspection regime for air conditioning equipment which is housed in commercial buildings. All of the acronyms which are used to label the various inspections, such as F-Gas, EPC, DEC, relate back to the Energy Performance of Buildings Directive (EPBD).

Statutory requirement air conditioning inspections

F-Gas Scheduled Statutory Inspections

If your air conditioning system has a capacity of over 3Kg refrigerant, you are required to have periodic F-Gas inspections. If you are unsure of your system capacity, call our experienced air conditioning engineers today on 01202 937 550, or email, and we would be happy to advise.

F-Gas inspections are designed to ensure the safe and efficient running of your air conditioning. The inspection must be carried out by an F-Gas Certified Engineer. How often F-Gas inspections are required depends on the operating capacity (size) of your air conditioning system which we have outlined below:

F-Gas Scheduled Inspection Required System Capacity
Every 12 months Systems over 3Kg refrigerant
Every 6 months Systems over 30Kg refrigerant
Every 3 months Systems over 300Kg refrigerant

F-Gas Statutory Inspection Requirements (BS EN 15004)

EC Regulation 842/2006 specifies that leakage checks should be performed, necessary repairs undertake, and harmful gases are recovered to prevent them leaking into the atmosphere. During the F-Gas inspection must be performed by certified companies and personnel.

An F-Gas Certified Engineer inspects the system to undertake the following:

  • All AC equipment is labelled with an asset number
  • A central asset log is produced to be held by the building manager, logging:

o   Maintenance history

o   Engineers F-Gas certificate number

o   Refrigerant added or removed

o   Unit serial numbers

  • Leakage checks are performed and necessary repairs are undertaken
  • Necessary labels are used on certain equipment

Energy Performance Certificates (EPC)

Energy Performance Certificates are designed to help increase energy efficiency, reduce energy consumption and operating costs, and limit the carbon emissions of your system. The inspections are conducted by a Registered Energy Assessor.

If the building is over 500m2, and your occupation started after April 2008, a whole building energy assessment should be conducted. Energy Performance Certificates are valid for 10 years.

Registered Energy Assessor Inspections

Registered Energy Assessor Inspections cover installations which do not yet require an Energy Performance Certificate. They should be performed within 5 years of your air conditioning system installation. As with Energy Performance Certificates, the inspections are designed to help you reduce energy consumption, improve system efficiency, reduce operating costs and limit the carbon emissions produced by your system.
