This answer addresses the question but does not give much information outside of a simple sentence.

What is self-isolation and which countries will it apply to?
section_content: Please note - these measures are NOT yet in force. We will set out further
detail, including from when these will be in force, in due course.
We will be asking people travelling to the UK to make some sacrifices to stop
coronavirus cases from being imported. In the same way as people in the UK
have made large sacrifices to control the spread of coronavirus.
So what we will be asking people to do on entering the UK is supply their
contact details and details of their accommodation, and to self-isolate in
their accommodation for 14 days, other than those on a short list of
exemptions.
We will set out further details shortly.

Reviewer feedback on this answer:
This answer relates to measures that will soon be into practice but does not outline whether all travelers must adhere to these measures.
the answer gives very vague and basic information about what to do when you return home to england. it mentions self-quarantine, but other than that there are really no details about what to do.

Answer passage (source: UK):
page_title: Guidance Travel advice: coronavirus (COVID-19)
section_headers: When you return to the UK: protect yourself and others
section_content: The rules for entering or returning to the UK are changing on 8 June.
Until 7 June
When you return to the UK from a flight from another country, go straight
home, avoiding public transport where possible. If you can, wear a face
covering if you need to use public transport, and see safer travel guidance
for passengers. Only people living in your
household should collect you on arrival.
If you are remaining in England:

stay safe and alert and only go outside for food, health reasons, exercise and recreation, or work if you cannot work from home
when you go out: always stay 2 metres (6 feet) away from other people, do not touch your face, and wash your hands frequently, including as soon as you get home

If you are travelling on to Wales, Scotland or Northern Ireland, follow the
relevant devolved administration guidance:

Welsh Government guidance and see transport advice
Scottish Government guidance and Traveline Scotland advice
Northern Ireland Executive guidance and Translink advice

If you start to have symptoms
For most people, coronavirus (COVID-19) will be a mild illness. However if you
start to have any of these symptoms:

continuous cough
high temperature
loss of or change in your sense of taste or smell

you must go straight home, self-isolate for 7 days and arrange to have a
test to see if you have coronavirus.
See the guidance for households with a possible
infection and call NHS 111 if your symptoms worsen. For further guidance,
visit gov.uk/coronavirus or visit
nhs.uk for specialist medical advice.
From 8 June
From 8 June, there will be new rules for entering or returning to the UK. You
will:

need to provide your journey and contact details when you travel to the UK
not be allowed to leave the place you’re staying for the first 14 days you’re in the UK except in very limited situations (known as ‘self-isolating’)

If you are planning to arrive back in the UK on or after 8 June, you must read
the guidance on entering the UK from 8 June.

Reviewer feedback on this answer:
The answer gives a lot of details concerning coming home to England from traveling abroad. It talks about self quarantining, as well as what to do if you start showing symptoms.
This answer relates to the guidelines for those returning or entering the UK, not whether or not these measures apply to all travelers.
