"A regulated price means people will switch off and think 'the government's looking after me',"
Flipper's mission is to ensure nobody overpays for energy again. We’ve made the tedious and complicated process of energy switching hassle-free for our customers. Flipper switches customers across the UK to the best gas and electricity deals, and has offices in Bristol.
