I'm moving from my current flat to a semi-detached two-bedroom in London. I'm losing Hyperoptic but my wife wants TV so I'm covered with a decent Virgin connection. I've always stuck with whatever the current utility providers were when we moved in but now I would like to look into getting a better deal. I found that if I Sign up to any First Control tariff with First Utility and get a Nest Thermostat E at no additional cost. Are they any good and do other utility companies also have this kind of deal? I really want to be able to control the heat and hot water from my phone. I've read that the comparison sites don't always list the best deals.
