The booklet received some criticism comparing it to Protect and Survive, a 1980s Public Information Film that instructed people on how to remain safe from nuclear war. Some sections of the media also accused the Government of "scaremongering", although information was provided on topics other than terrorism.
Soon after the website accompanying the booklet was launched, a spoof website appeared, www.preparingforemergencies.co.uk, said to be from "HM Department of Vague Paranoia"; it parodied the seemingly obvious advice given by the booklets, and gave such advice as: "Alien Invasion: Negotiate using sign language, if possible. Failing that, and assuming they aren't armed with futuristic ray guns, run like hell. The Home Office initially objected to the website, stating that the URL was too similar to that of their own website, www.preparingforemergencies.gov.uk, and threatened to close the website down. However, after a link to the official website was added, the Home Office conceded the issue, and allowed the site to remain online.
