I am a caregiver and I think in the UK you have similar services to us.
You should be able to access help for your needs via the hospital, doctor or social services,you are usually given to an agency
From this you will be able to get help in a wide range of areas including personal cares,shopping ,housework,transportation and gardening
I am not sure which of these are income tested in your country but if you ring Age Concern they probably will have all the significant information
I have just been down visiting family and my mother has recently moved into an apartment after my fathers death.My brother and his family live close by and do most things for her but she wanted to hire a cleaner(her income is too high to receive help for free)Do check around as when looking in the yellow pages, she had to hire them for at least two hrs the minimum cost was $90,so I rang age concern and was put onto an Agency down there were it was $33 for 1hr which is all she needs once a fortnight,so if you do have to pay it is worth shopping around,
Last thing the RSA also does transport here really cheaply.
