Eligibility for compensationNoise insulation (NI)Temporary or permanent re-housing (TRH)

Acoustic centre setback distance from boundary of works (m)

NB:

As per BS 5228, the noise insulation (NI) trigger level of 75dB(A) (facade level) applies to the period 08:00-18:00. The related trigger level for temporary rehousing (TRH) is 10dB higher, at 85dB(A).

Outside this time period the trigger levels would be lower.
