From Hansard, 11 September 1941, this is the response of the Home Secretary, Herbert Morrison, regarding the change of name:
Mr. Noel-Baker asked the Home Secretary whether he will indicate the reasons for the changes in the title of the Civil Defence services and the consequential alterations in the uniform badges?
Mr. H. Morrison - The change in title from Air-Raid Precautions to Civil Defence was decided upon in order to mark the developments which have taken place, and to emphasise the growth and increased importance of the services and their essential unity with other branches of civil defence. Moreover, while "Air-Raid Precautions" may have been an appropriate term in the days of pre-war preparations, it is, in my judgment, neither dignified nor stimulating enough for the splendid body of men and women who have rendered active and heroic service in the face of fierce enemy attack. The Civil Defence badge will be supplied on new uniforms as production changes can be introduced. Separate Civil Defence badges are not being supplied in replacement of existing A.R.P. badges.
