As part of the second phase of the Energy Efficiency Plan, from 1 January 2027, the government is making it compulsory to install programmable thermostats in all homes and offices, in order to promote energy efficiency. Decree no. 2023-444 of 7 June 2023 making it compulsory to install programmable thermostats in homes and offices has just been published!
This measure applies to all types of boiler (individual, collective, running on gas, oil, wood or coal), as well as heat pumps and heating appliances equipped with ventilation.
The programmable thermostat is connected directly to the existing heating system. It offers a technical solution enabling users to regulate their energy consumption according to their needs. The government's main aim is to reduce energy wastage and encourage more responsible practices.
In terms of cost, it should be noted that programmable thermostats are available in a price range from €40 to €150, depending on the model chosen.
The professional responsible for servicing the boiler will need to check that the thermostat is present and working properly when he or she carries out the work.
If the professional finds that the thermostat is missing or malfunctioning, the precise consequences have not yet been defined. To date, there are no specific penalties. However, it is important to point out that the government may take subsequent measures to promote compliance with this requirement and encourage installations to conform.
Will the absence of a programmable thermostat in a home be an obstacle to its sale from 1 July 2027?
The text of the law makes no specific mention of this situation. To address this issue, we can draw a parallel with the sale of a home fitted with a boiler that has not been serviced annually. Unless otherwise stated, it will be the seller's responsibility to inform the buyer of the absence of a programmable thermostat, so that the buyer is aware of it.
