A landlord or Management Corporation Strata Title (MCST) with a master-sub metering arrangement can buy electricity from a retailer of his choice either under the En-Bloc Contestability Scheme or Demand Aggregation Scheme.

Under the En-Bloc Contestability Scheme, the landlord or MCST (i.e. the master-metered account holder) will buy electricity for the entire premises on behalf of all sub-metered tenants, from the selected retailer at an electricity rate agreed between the landlord and the retailer. The landlord is required to obtain the consent of all the tenants to buy electricity on their behalf.

If a tenant subsequently decides to opt out of this arrangement, all tenants and the landlord will revert to buying electricity from SP Group at the regulated tariff.

A landlord or MCST who is unable to obtain the consent of all tenants can buy electricity from a retailer under the Demand Aggregation Scheme. Under this scheme, the landlord can carve out part of the common services load and the load of one or more consenting tenants under a new sub-metered account. The remaining tenants can continue to buy electricity from SP Group at the regulated tariff, or from electricity retailers if they meet the contestability criteria.

You are advised to check the commercial terms and conditions of the contract arrangement signed between you and your landlord before deciding to opt out of the En-Bloc Contestability Scheme or Demand Aggregation Scheme.

Management Corporation Strata Title (MCST) for private residential estates will need to go through the Demand Aggregation Scheme in order to be eligible to switch to a retailer.

Under this scheme, the MCST can carve out part of the common services load under a new sub-metered account.

A landlord who is unable to obtain the consent of all tenants can buy electricity from a retailer under the Demand Aggregation Scheme. Under this scheme, the landlord can carve out part of the common services load and the load of one or more consenting tenants under a new sub-metered account. The remaining tenants can continue to buy electricity from SP Group at the regulated tariff, or from electricity retailers if they meet the contestability criteria.

If any of your tenants withdraw their consent for the landlord to buy electricity on their behalf, all consumers under the En-Bloc Contestability Scheme or Demand Aggregation Scheme (whichever is applicable) will revert to buying electricity from SP Group at the regulated tariff. You (i.e. the landlord) will need to inform SP Group of your tenant's decision to opt out of the arrangement. If you require clarifications on the process after your tenant's withdrawal of his consent, you can contact SP Group at 1800-233 8000 or choice@spgroup.com.sg for assistance.

Consenting tenants will have to close their respective sub-metered accounts with SP Group, as the electricity consumption of these tenants will be subsumed under:

• The master-metered account in the En-Bloc Contestability Scheme; or
• The new sub-metered account (registered under the landlord) in the Demand Aggregation Scheme.

The landlord and tenants will have to agree on the commercial arrangement, which would typically include the electricity rate payable by the tenants to the landlord. Tenants will receive their electricity bill from their landlord or the landlord's retailer. SP Group will no longer bill the tenants for their electricity consumption.
