Do not be shocked if you were previously compliant but now are rated as Requires improvement as many providers are now finding.
Compliant under the old regulatory system does not equate to Good under the CQC's new ratings system.
Compliant ment you were simply meeting the basic regulation. That is obviously just OK and does not mean good or that there is no room for improvement to become good.
You don't even have to be in breach of a regulation to be rated Requires improvement by the CQC. A simple good practice recommendation in your CQC report can result in a rating of Requires improvement.
