Under CERT, energy suppliers are required to deliver measures that will provide overall lifetime carbon dioxide savings of 185 MtCO2 (increased from 154 MtCO2 in 2009) – equivalent to the emissions from 1 million homes each year. It is expected to require energy suppliers to need to invest around some £3.2bn in order for them to meet their obligation.

CERT requires suppliers to focus at least 40 per cent of their activity on a 'Priority Group' of vulnerable and low-income households including those in receipt of eligible benefits and pensioners over the age of 70 by increasing the energy efficiency of these households.
