Changes effective from 23 September:

From 23 September, the Bailiwick of Guernsey will accept valid vaccination certification from all international jurisdictions.

People who test positive for COVID-19 will be required to isolate for 10 days (compared to the current 14 days).

There will also be some changes to the general rules for people identified as the contact of a positive case:

  • Anyone aged 18 or under who is a contact will not be required to self-isolate regardless of their vaccination status. They will be required to undergo lateral flow testing.
  • Anyone aged 19 or over who is fully vaccinated will not be required to self-isolate.  They will be required to undergo lateral flow testing and take a single PCR test.
  • Anyone aged 19 or over who is not fully vaccinated will need to self-isolate for 10 days. They will also be offered a PCR test and a daily lateral flow testing.

From 4 October, there will be significant changes to the rules for travel to the Bailiwick. Please go to: Travel from 4 October | States of Guernsey - COVID-19 ( for the latest information.

A person may be required to self-isolate for a number of reasons, such as:

  • If they test positive for COVID-19
  • If they develop symptoms of COVID-19
  • If they have been identified as a contact of a confirmed positive case of COVID-19 and been told to isolate by Public Health
  • Or if they have travelled to the island from outside of the Bailiwick of Guernsey

Do I need to self-isolate?

If you are fully vaccinated but are:

  • awaiting the results of a COVID-19 test,
  • are a contact or possible contact of a positive case, over 19 years old and not fully vaccinated,
  • if you have test positive for COVID-19

you will receive advice from Public Health based on individual circumstances regarding what your isolation requirements are.


If you are not fully vaccinated (meaning both unvaccinated or partially vaccinated) please read the following guidance.

What is self-isolation?

Definition: To self-isolate means to keep yourself separated from any other person to prevent infection or contamination.

If you are not self-isolating in a household bubble, but are in a location where other people live, you must separate yourself physically from others within the household.

A person can self-isolate:

  • At their home;
  • With friends or family (provided there are suitable facilities);
  • In a hotel or self-catering accommodation;
  • On a private boat or motorhome/caravan (as long as the holding tank has capacity to last the length of the self-isolation).

During self-isolation you must:

  • Remain in your self-isolation accommodation at all times, except for getting emergency medical care or to have a COVID-19 test;
  • Not leave your self-isolation accommodation to go to work, school or public areas.
  • Not open your door to anyone who comes to visit, whether they are dropping a delivery off or wanting to come for a social visit;
  • Ask for help if you require groceries, other shopping/supplies or medication. These should be left on your doorstep so you do not come into contact with anyone.

Please note that Critical Workers must follow the requirements set out in their exemption paperwork. This may include additional COVID tests. 

What if the person self-isolating is a child/young person?

If the person who is required to self-isolate is a child or dependent adult who cannot self-isolate on their own, a carer will need to pair with them to self-isolate away from other people, including other householders if unvaccinated, for the duration of the self-isolation period.

Providing that the household is not self-isolating in a household bubble, and that the person self-isolating is compliant with all of the rules, the other residents of the household are not subject to any restrictions and can go about their business as normal.

Self-isolating with family or friends in a household bubble:

You need to consider the following:

  • That wherever possible, it is preferable for you to self-isolate on your own.
  • That you may also self-isolate with your travel party if you have all travelled together but need to be aware that your period of self-isolation may have to be extended if one of the travel party tests positive for the virus that causes COVID-19.
  • That if you choose to self-isolate with your family/household, then all family members including children will be required to follow the same self-isolation rules if they are not fully vaccinated. If they are fully vaccinated, then you will be able to mix with them, but no one else from outside your household. Unless you receive separate guidance from Public Health, there are no self-isolation restrictions to the householders who are fully vaccinated, so they can continue as normal (i.e. they can leave the house).
  • The risk to the other household members, especially those who are elderly or have underlying health conditions.
  • That those you isolate with may need to be tested when you are tested.
  • That you must remain in your place of self-isolation and not leave for any reason, except for where you have a reasonable excuse for leaving, e.g. receiving emergency medical care or undergoing a COVID-19 test.
  • That you cannot go to work, school, or public areas, and must not use public transport or taxis until you have been told that is safe to do so. You will need to ask for help if you require groceries, other shopping or medications. More information is available on the Food and Drink Deliveries webpage.
  • That if you decline to be tested then your mandatory self-isolation period may be longer.

If you choose to self-isolate in a household bubble with any person who did not travel to the Bailiwick with you, you should (a) register the names of every person in that household bubble on as soon as possible whether vaccinated or not and (b) inform the booking team of this fact when arranging any PCR tests.

If you are unable to self-isolate away from other members of your household, you may need to consider self-isolating at an alternative place, for example a hotel or self-catering facility.

If you are self-isolating on your own within a family home and the rest of the household are not fully vaccinated, you should stay in a well-ventilated room with a window to outside that can be opened and keep the door closed. All meals should be prepared by someone who is not self-isolating, delivered to your room (ideally on a tray) and you should not collect the food until the other person is at least two metres away from the door.

It is strongly recommended that you use a separate bathroom from the rest of the household. If you have to share these facilities:

  • always clean the bathroom, toilet and sink areas thoroughly after use, not forgetting door handles and taps and toilet handle/button.
  • consider drawing up a bathroom rota for washing or bathing, with the isolated person using the facilities last, before thoroughly cleaning the bathroom themselves.
  • ensure the isolated person uses separate towels and toiletries from other household members, both for drying themselves after bathing or showering and for hand hygiene purposes.

When cleaning bathroom surfaces, use a bleach-based product or a standard detergent cleaning product. Use a single-use cloth or kitchen roll. See the ‘Waste and Laundry’ section below for how to dispose of used items.

I have travelled into the Bailiwick of Guernsey, do I need to self-isolate?

If you have travelled to the island from outside of the Bailiwick of Guernsey you may need to isolate. If you are unsure of whether you will be required to self-isolate on arrival into Guernsey, please go to: Current Travel Requirements | States of Guernsey - COVID-19 (

Once you have checked your vaccination status and/or travel history, if you are required to self-isolate please follow the guidance on this page. 

Please note that this guidance has legal force and must be complied with. Failure to comply with it may constitute a criminal offence punishable by a fine of up to £10,000 and/or 3 months' imprisonment.
