Assistance for medical appointments for elderly relative in UK

I am seeking a reliable caregiver to accompany my elderly parent to medical appointments in the United Kingdom. The role includes transportation support, helping with check-in, taking notes on medical advice, organizing follow-up tasks, and ensuring safety during visits. Familiarity with NHS procedures is a plus. The caregiver should be patient, communicative, discreet, and able to manage mild anxiety or mobility challenges. Ideally available on weekdays, with some flexibility for occasional early morning or late afternoon appointments. Car access is not strictly required, but reliability and punctuality are essential.
