Mae’r cynllun yn agored i berchnogion cartrefi ar draws ardal estynedig Tasglu’r Cymoedd, sy’n estyn o Sir Gaerfyrddin yn y Gorllewin i Dorfaen yn y Dwyrain. Cafodd y ffiniau eu hestyn y llynedd i gynnwys Cwm Gwendraeth a Dyffryn Aman hefyd.
The scheme is open to home owners across the extended Valleys Taskforce, which runs from Carmarthenshire in west Wales to Torfaen in east Wales. Its boundaries were also extended last year to include the Gwendraeth and Amman Valleys.
