I have to say that I consider myself fortunate compared to the many other poor customer reviews expressed about Avro Energy (AE). My dual fuel supply contract with AE commenced in July 2020 at very competive prices. Every month I received an email reminder to submit my meter readings, which I did online. Resultant monthly billing was accurate. Toward end of 1st year fixed term tariff I received a end of tariff notification and selected a new 1 year fixed term offer, also very competitive versus other providers. I had accumulated a credit on my account which I asked to have refunded on 19. May and, whilst I had to send 2 email reminders, on 4. June AE confirmed that they would refund the credit balance which subsequently arrived in my bank a/c on 23. June. Therefore my overall experience with AE over the past 15 months has been positive.... Food for thought though: what with the significant rise in wholesale energy prices over recent months, it will be interesting to see whether Avro's business model is sustainable, or whether I will need to seek a new energy supplier....
