In 2003 the Building Regulations introduced Approved Document E (ADE 2003) which
required that sound insulation testing is carried out on 10% of all new attached
homes, conversions, some historic conversions and rooms for residential
purposes. Developers now need to provide Building Control with a certificate
that the sound insulation requirement for the dwelling has been met.
Approved Doc E (2003) requires that test bodies are either UKAS accredited or
registered with the Association of Noise Consultants (ANC).
