Unfortunately this very application, Gov.uk Notify, is currently being used by Councils to send emails to residents directing them to an outsourced company's website, https://www.householdresponse.com, to input sensitive details about where they live.

The emails are phishy to the extreme and there's no indication or way to verify that it's an official service. See for example https://www.bleepingcomputer.com/news/security/uk-gov-keeps-...

While some parts of Gov.uk are done well, there are still terrible practices everywhere due to cheapness and ignorance and presumably because the Gov UK people can't do everything, unfortunately, even though it would be cheaper and better if they did.
