How Does Lot 20 effect Electrical Heating?

From 1st January 2018, all installed electric space heaters manufactured for sale in the UK which use electricity must comply with a minimum efficiency standard. The aim of this legislation is to remove inefficient technologies and reduce the energy used by the products that heat our homes, helping to achieve our overall carbon reduction targets.

Lot 20 requires any installed electric heater manufactured from January 2018 to have an electronic thermostat with a 24-hour, 7 day timer with either adaptive start or an open window sensor.

This legislation only affects heaters that were manufactured after January 2018, so if you have recently invested in new installed home heating that doesn’t comply, then do not panic. If you are looking to upgrade your heating however, now is the opportune time due to the new requirements for energy saving capabilities.
