The Government have not produced estimates of the potential financial contribution to the UK economy of the microCHP industry. Any such estimates would depend on market size, which would depend in part on the nature and level of support to the technology, as well as a range of commercial factors, and the nature of the manufacturing process for the different technologies relative to conventional boilers.
The Carbon Trust is carrying out field trials on micro CHP. An interim report was published in 2007, and final results should be published shortly.
