GP Patient Survey 2018
These results were issued on the 7th August 2018. You can see on a single page how a practice compares to the local and national averages, as well as making comparisons between individual practices. There is also a section on 'patient experience'.
You may need to be patient as the site seems to be quite slow but that is probably the volume of users.
You will need the postcode for your Surgery and then access the Survey here
