I believe my noble friend may be referring to the low rate of registration for lateral flow tests issued for asymptomatic testing. That is something we are looking at very carefully. Around 40% of people say they have taken tests but not registered the results. NHS Test and Trace is taking steps to improve the registration of test results by streamlining the reporting process and improving communications about the importance of reporting results.
My Lords, I do not have data for those who might be physically checked in their home, but the ONS conducts surveys of those who have been asked to isolate, which show a higher compliance rate of about 80%. The Government’s focus in ensuring isolation is to provide the right incentives and support for people to isolate, including, for example, the £500 self-isolation payment for those on low incomes. We take enforcement measures, but we seek to persuade and then enforce.
