Natural Philosopher randomly hit the keyboard and produced:

I am not at all sure that is true. If making a 'material alteration' you
are required to esnure that the alteration is to standards.

An alteration is only material if it adversely affects a Relevant
Requirement (currently Part A- structure, Part B- fire safety and Part
M- access & facilities for disabled people), or a controlled service
or fitting (drainage and waste disposal, combustion appliances, and
for dwellings, replacement windows or central heating boilers,
vessels, etc). Part K is not a relevant requirement, so if the work
consists wholly of replacing a stair, it is not controlled.

If it is being altered as part of other work (an extension or
structural alteration) then it should be made no worse than
previously.
