The conversion efficiency of combined heat and power installations is undertaken within the UK's CHP quality assurance programme (CHPQA), the means by which the Government assess the environmental performance of CHP plants to ensure they deliver primary energy savings of at least 10%.

The conversion factors for the most recent gas-fired CHP plants certified under CHPQA demonstrate electrical efficiencies in the order of 33-39% and heat efficiencies in the order of 40-45%, depending on the size and type of the plant.
