Tariffs and payments: Domestic RHI

Mae’r dudalen yma ar gael yn Gymraeg.

Tariffs set the rate for your Domestic Renewable Heat Incentive (RHI) payments. People who join the scheme and stick to its rules receive quarterly payments over seven years. The rates are set by the Department for Business, Energy and Industrial Strategy (BEIS), formerly known as the Department of Energy and Climate Change (DECC).
