My suggestion (about 5 or 6 years ago)
Was for people to be able to register with 2 different doctors, meaning you could have a surgery near both home and work. Seeing as most people have a trek from home to work and back again, if you could nip out during the working day to the doctors, rather than taking the morning/afternoon to go it would be better for the employer and the patient.

I also suggested the stopped giving out fully subsidised prescriptions before 10am and after 5pm, meaning those who pay towards the cost of their medication have a better chance of getting a convenient appointment. Nothing to stop the retired/kids from having appointments at the most convenient times, but they should be expected to pay towards prescription costs if they choose to go at a plum time*.

*Common sense exceptions would apply.
