Mill Road Surgery vs Petersfield Medical Practice
Two GP practices in the same primary care network, a short way apart. Side by side, with the margin of error on every figure.
Can the survey tell them apart?
Mill Road Surgery and Petersfield Medical Practice cannot be told apart on the Practice Grade. The likely ranges overlap, so the data does not show that one is ahead of the other, whatever the two numbers are.

“Clearly higher” appears only when a practice’s whole margin of error lies above every other practice’s here. When the margins overlap, the survey cannot tell the practices apart and nobody is pointed out. A practice never gets a mark for being lower.
The Practice Grade weighs the survey and access, from NHS appointment and phone data; the other survey questions are from the 2026 GP Patient Survey. The facts are from NHS England, the Care Quality Commission and OHID, are not part of the grade, and are shown as each practice’s own record. NHS England advises against ranking practices on the Friends and Family Test or on appointment figures, and we point nothing out in the facts, vaccination or screening rows.
