The GP Patient Survey (GPPS) is commissioned by the Department of Health (DOH) and run by Ipsos MORI. The GPPS is administered by post and not in the surgery and is sent out every quarter. The survey is sent to random samples of patients who have been continuously registered with a general practice for at least 6 months. All four quarters are published in the summer of each year. The results can be found via the following link:
