Green Electricity Marketplace (GEM) was formed in 2000. With the liberalisation of the UK electricity market and the growth in renewable energy we felt that a website which could list and analyse available green tariffs would encourage uptake of these tariffs and help to promote renewable energy.
Unlike most switching sites, GEM is focused on renewable energy and provides its own perspective on green tariffs.
The website has been widely recognised for the information it provides: by environment groups including Greenpeace and Friends of the Earth; by consumer groups including the National Consumer Council; by businesses like Samsung UK; and by the media including BBC Newsnight and The Independent.
In 2016, in order to demonstrate the independence of our tariff ratings, GEM stopped accepting referral fees from suppliers. While grateful to those users who donated to the site, the donation model did not provide sufficient income to justify the time needed for maintaining the site and listing the ever increasing number of green tariffs, and we had to suspended tariff listings in September 2018.
To restore a switching service, since August 2019 we have partnered with switching services which receive income from some switches made. We receive a proportion of referral fees from switches and aim to be as transparent as possible about these.
Big Clean Switch only lists suppliers which pay them referral fees, which may mean some tariffs which would meet their other criteria are not listed. This approach allows them to carry out a detailed assessment of each tariff to ensure it meets their environmental and customer service standards. We receive a proportion of these referral fees.
Homebox aims to lists all tariffs, with a filter for Green Plans. They get referral fees from some of the suppliers. We receive a payment from Homebox for every switch made through this site.
