Some letting agents have cosy deals with energy suppliers whereby tenants are tied into a tariff they didn't choose. We know this happens, but not a lot else. We want to know more about how common this is and which agents are doing it.

We want to hear from you if you have ever been prevented from changing energy supplier, or if you have walked away from a tenancy that would have tied you into a dodgy looking deal. 

Please note: we will treat any information you give us in the strictest confidence unless you give us your permission to share it.
