A number of households across the UK are now due a refund from their energy suppliers following an overcharging error.
The refunds, totalling £800,000, affect customers with "feed-in (FIT) tariffs", reports the Mirror. These tariffs are renewable energy deals available to homes with devices like solar panels or wind turbines.
Energy regulator Ofgem has said that customers of Good Energy and F&S Energy were charged with an “unauthorised administration” fee.
