I have been asked to voice my opinion far too soon, but from starting the change of my energy supplier through Energylinx, so far they have been very efficient and kept me informed that the process is underway and have made a moderate cashback offer that I trust they will honour after the switch has been processed. I had spent time looking at the switch through up to 11 comparison sites and because the offer was the same monthly estimate, I chose Energylinx based on previous experience and the cashback value that was better than the rest.
