RIGHT OF REPLY

Every provider was sent its full assessment — all 25 criteria, our verdict on each, the exact URL we relied on and why — and given 14 days to correct us before anything was published. This is what came back. 1 of 10 replied.

A provider that did not reply has neither endorsed nor disputed these scores, and we do not read anything into the silence. A correction sent after the window still gets acted on: send it to [email protected] and we will re-score and say that we did.
