The flight arrival 14 day quarantine to the UK seems bizarre at this stage of the pandemic.
Countries with a strong incoming tourist sector/business travellers sector to their economy but who have managed low rates of infection have all used the flight arrival quarantine as part of their tactics from much earlier in the pandemic's outbreak (Jamaica, New Zealand, Taiwan, Israel, to name but a few)
From The Guardian:
"There has been mounting scrutiny of UK border controls in the run-up to the crisis. It emerged that 18.1m people arrived in the UK by air between 1 January and 23 March and
only 273 were formally quarantined.
Until 13 March the government advised incoming passengers from specific hotspot countries, including Italy, Iran and parts of China, to self-isolate, but this was dropped – “inexplicably”, according to Yvette Cooper, the chair of the home affairs select committee."
