Hi headabovethewater
It will make no difference, I did speak to the DWP about fit notes a little while ago about gaps in the claim dates, DWP prefer no gaps but will over look up to 10 days depending on each individual and their circumstances.
If you live next door to a surgery they may be less forgiving than if you lived in the middle of nowhere and struggle to get transport.
