The following interpretations have been withdrawn.

N02 Notification of alterations – exemption for minor work - related to how notification requirements applied to minor alterations or extensions of water systems. It was considered that the advice was no longer needed, as the guidance within the regulations is sufficient.

N03 Approved Contractors’ exemption from Notification and Compliance Certificates - advice related to the issuing of certificates and over time the approved contractors’ schemes have updated their terms and conditions and so the advice is no longer required.

WQ06 Preventing stagnation in a fire sprinkler system - advice related to the use of an outlet at the end of a fire sprinkler system to reduce water stagnation within it. The advice has been withdrawn to prevent confusion.
