Using alternative codes and standards to satisfy regulation 30

As an alternative to the codes and standards referenced in paragraphs 2.2 to 2.9, the documents referred to in paragraphs 2.12 to 2.19, which were withdrawn by the British Standards Institution on 31 March 2010, may be used to satisfy the requirements of the Building Regulations. However, designers will be required to demonstrate appropriate use of withdrawn standards in the circumstances of the building work. Using withdrawn British Standards may continue to be acceptable where it can be demonstrated that design reliability can be achieved. Particular care must be exercised in relation to withdrawn codes used to calculate wind and snow loads where the effects of climate change may render these unsafe. Consistency of design approach is required and designs should not inappropriately mix Eurocodes and withdrawn British Standards.
