Nine out of 10 MPs believe heating controls should be fitted when replacing a boiler, according to a survey conducted by Energy and Utilities Alliance (EUA).
Currently, there is no such requirement on households or for government-supported schemes.
EUA has been campaigning for heating controls to be recognised as an important factor in driving down energy bills and maximising the benefit of having a new boiler fitted.
There are over 1.5 million new boilers fitted each year, and it is estimated that 70% of homes do not have the minimum heating controls installed that are specified in Building Regulations.
According to the Energy Savings Trust, a new boiler with heating controls can save the average homeowner £575 a year.
EUA chief executive Mike Foster said: “It should be mandatory for a full set of heating controls to be fitted when a boiler is replaced. It is the ideal time to add these to the existing heating system of a home and maximise the savings the consumer will make.
“All government-supported schemes like the Green Deal and ECO should encourage this approach. MPs overwhelmingly support the measure and the government needs to show leadership on this.
“New smart controls make an even bigger impact by allowing the boiler to react automatically to outside temperatures, which all helps to keep bills down. Recognising the merits of these controls and encouraging their use would be a positive step.”
