These Regulations document the procedures to be used to assess the requirement to provide noise insulation to residential properties adjacent to new and altered highway schemes. The Regulations provide criteria for overall noise levels, the contribution from traffic on the new or altered highway, a distance cut off of 300m, and they only apply to roads built or altered since October 1969. The Regulations also contain a power to enable noise insulation to properties as a result of construction noise from highway schemes.

Properties that are eligible for noise insulation are provided with a package of measures including secondary glazing and acoustic ventilation for qualifying rooms.  In some circumstances, a grant towards the cost of the works can be provided.
