Consumer Advisory |
Consumers must only purchase NEA-registered appliances found within NEA's Database of Registered Goods. We need the public's support to report any regulated goods that do not have the Energy Label or are not registered to NEA_energylabel@nea.gov.sg.
Consumers are strongly encouraged to look out for Energy Labels, which help consumers identify more energy efficient appliances, when purchasing household air-conditioners, refrigerators, clothes dryers, televisions, or lamps, in any local physical shops or from online shopping platforms.

In order to help consumers better identify the more energy efficient models and spur suppliers to offer more efficient products, the energy rating system for air-conditioners, refrigerators and clothes dryers was revised on 1 September 2014.
The revised rating system is more stringent than the old one. Most models rated 4 ticks under the old energy rating system [PDF, 497.62 KB] are now assigned a rating of 2-tick under the revised rating system.
Currently there are few models in Singapore rated 4- and 5-tick, but this will change over time. The revised 4- and 5-tick bands will encourage the developers to introduce more high efficiency models into Singapore in the future. Consumers can look forward to greater choice and more cost savings.
The current tick rating is defined as follows:

1 COP100% is defined as the ratio of total cooling capacity to effective power input at full load cooling capacity
2 For split (inverter) type air-conditioners, the model shall meet both the minimum COP100% and weighted COP
3 Weighted COP = 0.4 x COP100% + 0.6 x COP50%
4 N is the number of indoor and outdoor units
5 Standby power is expressed in Watts

where
- Coefficient of Performance (COP) is ratio of cooling capacity to effective power consumption at T1 test conditions under ISO 15042(2017).
- Effective Power input is the average power input to the equipment obtained from operation of compressor(s), electric heating devices used only for defrosting, all control and safety devices and operations of all fans, whether provided with equipment or not.
