I think your clerk, CWT, may not be correct. If you are a member of a charity, community organisation etc. in a management role, even if you do not benefit personally, it can still be a registrable interest and should be declared on your declaration of financial interest form and at the relevant point in a meeting whenever the charity, etc. is discussed. The exception to the need to declare this is when your appointment to the charity etc. is made as a representative of the council on that committee/charity etc. I agree, it can be very useful to have a parish council representative on charitable and community bodies within the parish.
