Try this link, I do some HR work as part of my role and this is what I use to guide me:

If a worker develops symptoms and orders a test
If a worker develops symptoms, they shouldrequest a free testas soon as their symptoms start.
Once they have ordered the test, they’ll be asked by the NHS Test and Trace service to provide details of anyone who they have been in close recent contact with. This will not automatically be all their co-workers, but anyone who meets the definition of a close contact.
A close ‘contact’ is a person who has been close to someone who has tested positive for COVID-19 anytime from 2 days before the person was symptomatic up to 7 days from onset of symptoms (this is when they are infectious to others). This could be a person who:
spends significant time in the same householdis a sexual partnerhas had face-to-face contact (within one metre), including:being coughed onhaving skin-to-skin physical contact, orcontact within one metre for one minutehas been within 2 metres of someone who has tested positive for COVID-19 for more than 15 minuteshas travelled in a small vehicle, or in a large vehicle or plane
Where an interaction between 2 people has taken place through a Perspex (or equivalent) screen, this would not be considered sufficient contact, provided that there has been no other contact such as any of those indicated above.
The contact tracers will not consider the wearing of personal protective equipment (PPE) as a mitigation when assessing whether a recent contact is likely to have risked transmitting the virus. Only full medical-gradePPEworn in health and care settings will be considered.
Medical-gradePPEshould not be purchased to circumvent self-isolation, as this risks disrupting critical supplies needed by the NHS and social care sector.
Alerting close contacts
When someone first develops symptoms and orders a test, they will be encouraged to alert the people that they have had close contact with in the 48 hours before symptom onset. If any of those close contacts are co-workers, the person who has developed symptoms should consider asking their employer to alert those co-workers.
Close contacts at this stage do not need to self-isolate unless requested to do so by NHS Test and Trace or a public health professional, but they should:
avoid contact with people at high increased risk of severe illness from coronavirus, such as people with pre-existing medical conditionstake extra care in practising social distancing and good hygienewatch out for symptoms and self-isolate if they also show signs of coronavirus
Employers may need to keep staff informed about COVID-19 cases among their colleagues. However, employers should not name the individual. If a co-worker is at risk because of close contact with the positive case, then they will be notified to self-isolate by the NHS Test and Trace service. Employers should make sure their workplaces are safe by regular cleaning and by encouraging good hygiene practice.
