Please read the following Facts
㊀ It is not compulsory for you to switch to a retailer. You can remain with SP Group to buy electricity at the regulated tariff if you prefer to do so.

㊁ Electricity is produced by the power generation companies. SP Group then transmits and distributes it to consumers through the national power grid. Your electricity supply stays the same whether you switch to a retailer or not. This is because SP Group will continue to operate the national power grid and deliver electricity to everyone.

㊂ Read the fine prints before signing up, some retailers charge miscellaneous fees such as retail service fee or paper bill fee. Please DO read very carefully before signing up and read the fine prints!

㊃ The SP current tariff are as below:
** Prices are before GST 7%**

㊄ Before you decide on which retailer, first ask yourself do you want to receive the same SP paper bill even after switching to a retailer?
