I'm a bit confused when did you jump from counselling to spiritual welfare.
Spiritual welfare is only exempt when supplied in the following manner "The supply, otherwise than for profit, of goods and services incidental to the provision of spiritual welfare by a religious community to a resident member of that community in return for a subscription or other consideration paid as a condition of membership."
So is this not being supplied direct by a counsellor as may be assumed from your original query but by a religious organisation that charges some sort of subscription, in which case your original query gave almost none of the useful detail. Also your query seems to indicate there's a chance of this being medically based, unless we're dealing with faith healers then I can't see spiritual counselling being anywhere near a medical procedure.
Generally (other than as above) counselling would only be exmept when supplied by a charity, a public body, or a state regulated welfare institution, or when supplied by "a person enrolled in ...the register of medical practitioners or the register of medical practitioners with limited registration"
