January price cap

If you're on one of our Variable tariffs, your energy prices will be rising from 1st January. We'll be in touch to let you know your rates and your new estimated annual energy costs.

Only these rates are changing, so check our fixed tariffs and be protected against price rises. And, if we bring out an even better tariff later – you can swap for free.
