Switching to Diamond Electric’s Maybank Saver Plan

The Maybank Saver Plan is an exclusive electricity plan available only to Maybank Cardholders who setup recurring card payment using Maybank Cards for the electricity bills.

If you are a residential consumer, and do not opt for a new AMI Meter (i.e. Smart Meter) to be installed by SP Group, it will take 5 business days.

No, there will not be any electricity disruption. The electricity infrastructure is still maintained by SP Group, which means that there will be no change to your existing meter (unless you opt for a new AMI Meter i.e. Smart Meter) or wiring.  Diamond Electric will only be taking over the billing and financial obligations pertaining to your electricity supply.

In the event any electricity retailer ceases to operate, the EMA has mandated that all their customers will be switched back to SP Group. There will not be any disruption to the electricity supply.

No. There will not be any change to your existing meter (unless you opt for a new AMI Meter i.e. Smart Meter) or wiring. Your meter will continue to be managed and read by SP Group.

No. Residential customers do not need to install a new AMI Meter (i.e. Smart Meter), however if you choose to have one installed by SP Group, then there will be a meter installation fee by SP Group that Diamond Electric will pass through to you.

You can view the current regulated tariff at this site: https://www.ema.gov.sg/Residential_Electricity_Tariffs.aspx

Security Deposit (Currently Waived for Residential Customers)

Your security deposit is calculated based on the last three months average electricity bill multiplied by two. Basically, a two-month bill amount is required to be placed as a security deposit. (Currently security deposit is waived for residential consumers when they sign up to our plans)
If less than three month’s bills are available, we will use the bills for calculation. In the event that no bills are available, we will apply the standard rate to determine your security deposit. Please refer to /resources/ for details on our standard Security Deposit rates.

SP Group will re-calculate the security deposit required by them in relation to the other services provided to you, such as water, gas, and waste removal services. The excess amount will then be credited to your SP Group account and be used to off-set your charges on subsequent bills for the remaining services provided.

Your Security Deposit may be adjusted, based on your average monthly electricity consumption from time to time, in accordance to the Security Deposit Formula indicated here.

Your Security Deposit will be returned to you after offsetting any balance in your account.
