A tenant crofter is in breach of the statutory conditions if they let their croft or part of it without the consent of the Commission. However, seasonal grazings lets are excluded from this provision. It is in order for a crofter to generate income by letting the land on a seasonal grazings let as part of their planned management of the croft. The Commission would encourage any unofficial use to be formalised either by a tenant crofter applying to the Commission for consent to a sublet of the croft for a period up to 10 years, or an owner-occupier crofter applying to the Commission for a short term let of the owner-occupied croft for up to 10 years. This would enable the sub-tenant or short term tenant to apply for certain types of grant assistance, which would be of benefit to the croft.
