Noise levels shall be assessed in accordance with the Chartered Institute of Environmental Health & Institute of Acoustics Briefing Note, Heat Pumps - Professional Advice Note - November 2022 (based on BS 4142:2014+A1:2019 methodology). Measurements shall be made at one metre from the relevant building façade, including the contribution from the sound reflecting from that façade. Rating level shall be based on the unit at both full duty and when in reverse mode, plus any adjustment for the characteristic features of the sound such as tones, impulsivity and intermittency. Should the assessment fail to demonstrate compliance, further action shall be taken and reassessment made, until compliance is achieved, which must be achieved within 6 weeks of the permission herein granted, or the unit shall cease being used until such time as compliance is achieved."}
