The UK government is one of the pioneers when it comes to promoting smart thermostats. The Energy Company Obligation (ECO) Innovation Funding and Boiler Plus regulation already came into effect in 2018. The Energy Company Obligation (ECO) is a government energy efficiency scheme to tackle fuel poverty and help reduce carbon emissions. Under this program medium and larger energy suppliers fund the installation of energy efficiency measures like the installation of smart thermostats in British households. It is up to the energy companies to determine which measures they choose to fund and the level of funding they provide.
The Boiler Plus standards defined by the department for Business, Energy and Industrial Strategy require additional energy efficiency measures when a gas combi boiler is installed. Smart thermostats are one of the four additional measures prescribed and are the cheapest and most selected method to be compliant with legislative obligations. In September 2020, the Green Homes Grant, a £2b government package towards energy efficiency renovations, went into force. Homeowners and landlords can claim up to £5,000 towards the cost of energy-saving measures which include intelligent heating controls. Low income households can get 100% of the costs of work covered up to £10,000.
In Ireland, the Sustainable Energy Authority of Ireland (SEAI) offers grants that are helping homeowners, business owners, communities and large industry reduce their energy costs and greenhouse emissions. All homeowners, including landlords, whose homes were built and occupied before 2006 can apply for the €700 Heating Controls Grant to upgrade their heating system.
