Building warrants for demolition, while nominally valid for three years, are usually granted subject to time limits, such as a time period from the start of the demolition to the completion of works.
This time limit should be set by the verifier in agreement with the applicant.
The information required on the existing building and on the method of demolition is intended for the purpose of allowing a verifier to judge what protective works are required to ensure the safety of the general public. Other details of any method statement prepared to meet health and safety at work legislation does not need to be checked by the verifier.
For building warrant approval, sufficient information is needed to ensure the requirements set in regulations 10 and 13 to 15 of the Building Regulations are met.
