Hi @tobee I was in this stage a while ago, and unfortunately "forced into it" is often what happens eventually, usually after a fall. It would be worth reading this book asap: https://www.amazon.co.uk/gp/product/0091901812/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
Ideally, you need to ask around your neighbours to find out where the good private care firm is, and then keep that information somewhere safe.
If/when a fall occurs, the NHS / social care machinery clicks into action and there will be a social care assessment:
https://www.nhs.uk/conditions/social-care-and-support-guide/help-from-social-services-and-charities/getting-a-needs-assessment/
This is repeated when there is significant increase in care needs.
The tricky part is that there comes a time when the person/people are not able to manage at home with family help, but might not be willing / ready to move into a home and then things get fiddly.
You can get carers at home, which can be cost effective if there are two people to be cared for, as that would be very expensive in residential care.
There are also assisted living flats, where there are shared carers on site: https://www.ageuk.org.uk/information-advice/care/housing-options/assisted-living-and-extra-care-housing/
You can learn a lot from reading existing threads.
Does your df have a diagnosis? It would be helpful to have that in case he goes into hospital. It would also be helpful to discuss with him what level of medical intervention he wants as his condition deteriorates. He will reach a point where he is unable to make decisions for himself about things like life-saving treatment for pneumonia, and the default response for the hospital is to automatically treat him, even if he is suffering quite badly, even when well.
You may want to find out how long he wants to keep going and what he is willing to put up with to acheive that. I have not in any way ever managed to get a sensible discussion about that in my family. It's the hardest thing on earth to be asked to decide whether your parents should receive life saving treatment when time is tight and outcomes are uncertain.
It's all a bit complicated tbh.
There are lots of other good threads on here that you can read to get a sense of what's going on.
