I have usually found bulb to br very good and consistent, however, since cajoling me with umpteen texts and emails to get a smart meter fitted I relented and to be honest it was going to be easier to read as previously I had dial meters, a nightmare to give readings. It was duly fitted, worked for one week in may, it's now November, so, after many phone calls and correspondence by email, they still haven't rectified the situation. They take £260 per month DD for dual fuel. I called the recently to ask for paper bills in future and to give me a price sterling of what they had charged me, again, a nightmare telling me it would take time, could I do it?! I said no because I have terminal cancer, it then took him 20- 30 mins to convert kw to pounds sterling? I called back next day to check the figures he had given me, only to be told, no, they are incorrect! They have blamed parts for faulty meters are on a container in China back in June and then tell me they will charge me £120 for an engineer to check it's a valid mistake on there part. I changed from Utility Warehouse because I wanted an easier life, they are a complete nightmare, NEVER switch to them! I am still waiting for a resolution to the smart meter. I'll be dead by the time they do!
