What the CQC ask for Vs what they actually mean
The CQC have already got your Statement of Purpose, so why ask for it again?
The eason is that you should have kept it up to date and told them of changes. What they are really asking for is your up to date statement.
Your Statement of Purpose is more than just a description of what you do, it is a formal record of your registration. It is a legal declaration of your place of business; who owns it; and the services your licence will provide.
Changes to the statement are a serious matter. Do not start revising your statement for the sake of making it "look better" as any changes you make are notifiable to CQC. If you do this and forget or fail to notify the CQC at the same time, you will have shot yourself in the foot because this can now be picked up as a breach of regulations.
