Tariff 31 (T31) is known as the ‘Super Economy’ tariff or ‘Night Rate Off Peak’ tariff and is charged at a lower rate than either T11 or T33.


T31 is normally connected to larger hot water systems, although it can be used for other purposes. Appliances connected to T31 have to be hard wired (they are not connected via a plug and socket).


T31 is only available for eight hours per night normally between 10pm and 6am, therefore you must have a large hot water system to ensure that your hot water does not run out during the day.


Other items that can be placed on T31 are water beds and heat banks. Solar hot water booster elements can be placed on T31. However, T33 is better for this purpose. T31 is approximately 54% cheaper than T11.
