All air-conditioning systems with an effective rated output of more than 12kW must be regularly inspected by an energy assessor. An inspection needs to be carried out within five years of its installation and then at five yearly intervals.
The relevant person must ensure that an air-conditioning inspection report (ACIR) has been produced and uploaded onto Landmark, the Government’s database, at www.epbniregisternd.com. The relevant person must also have a copy of the most recent air-conditioning inspection report at all times.
What is an air-conditioning system under the regulations?
An air-conditioning system is any system where refrigeration is used to provide cooling for the comfort of occupants. This does not include separate refrigeration, for example a cooling system for cold stores, pharmaceutical production or IT server rooms.
If a number of air-conditioning units within a building are controlled by a single person and have an effective rated output of more than 12kW, they are considered to comprise a single air-conditioning system and so need to be inspected.
Who is the relevant person?
The relevant person is the person who controls the technical functioning and operation of the air conditioning system. This does not need to be the person who adjusts the day to day temperature.
What happens if the relevant person changes?
The outgoing relevant person should provide a copy of the inspection report to their replacement.
A person who has recently taken over responsibility for operating an air-conditioning system and has not received an ACIR must arrange a new inspection within three months.
How do I get an ACIR?
The only person who can produce an ACIR for your building is an energy assessor accredited to produce an ACIR. You can find an accredited energy assessor in your area at www.epbniregisternd.com.
Are there any penalties for not having an ACIR?
Yes, the penalty is £300 for failing to have your air-conditioning system inspected or failing to have a copy of the ACIR.
For more information about penalties see our Enforcement policy page.
Further guidance about ACIRs is available in our guidance document 1:
