I'm not sure what you mean by 'Selection'.
The British Army never stops recruiting, you can sign up all year round.
If, however, you are referring to a specific regiments selection process of which I can only think of one that's pertinent, the 22nd Special Air Service, you would do well to contact your local recruiting office and pose the question to them.
Be aware they won't answer questions pertaining to the S.A.S though ,not many people will.
