It's vital that you don't introduce infection to the house of an immunocompromised person, but there isn't such a high risk of spreading infection from the house.
How to collect items from someone who is self-isolating because they are immunocompromised.
If you need to collect an item (e.g. cash) from someone who is self-isolating because they are immunocompromised, it is essential that you do not create any risk of passing infection to them.
Before you arrive, ask the self-isolating person to place the items in a disposable bag, or one which they do not wish to keep.
Travel to see the person, in a way which minimises your risk of exposure to the virus.If possible, travel by pavement, a private car in which you’ve wiped down all the surfaces you’ll touch with bleach solution, or a taxi.If you must use public transport, try not to touch surfaces with your hands, use hand sanitiser after travelling if available, or wear gloves which you can change.If wearing gloves while travelling, remove these without touching the exterior with your bare skin. (illustrated technique, video technique)
As you approach the person's home, phone/text/etc them to open the door.If they live in a block of flats or other building with a communal entrance accessed by a buzzer, call/text and ask them to buzz you in, rather than pressing the button.
Remain at least two metres away from their front door.
Ask the self-isolating person to place the bag of items immediately outside the door, then ask them to shut the door or to back away inside at least 2 metres.
Once the door has been shut, pick up the bag, without touching any of the surroundings.
If the person doesn't want to put the item outside the door (for example, because of the weather), you should take additional precautions.
As you approach, call/text the person and ask them to open the door.Do this after removing any gloves worn for travelling, so that you don't transmit any virus from these to your phone, and before you put on (fresh) gloves, so that you don't transmit any virus from your phone to them.If they live in a block of flats or other building with a communal entrance accessed by a buzzer, call/text and ask them to buzz you in, rather than pressing the button.
Use hand sanitiser after phoning if you have any.
Put on (fresh) gloves if you have any, ensuring that you touch only the cuff of the glove with your bare hand. (illustrated technique)
If there are plenty of masks available in your area, wear a mask for this; if not, prioritise masks for healthcare workers and people who must enter houses to assist with personal care.If you do have a mask, put it on before putting on your gloves, to minimise the risk of transferring any virus from your face to your gloved hands.

Remain at least two metres away outside the door, and ask the self-isolating person to to put the bag of items on the floor immediately inside the doorway.
Ask them to move at least two metres away inside, then pick up the bag without touching any of the surroundings. Do not step through the door.
Step back at least two metres away outside to allow the self-isolating person to close the door.
