I woke this morning (03/01/18) to find my new (10 mths) boiler had shut down with an error. I called Northern Gas but was unsure which option to choose as there wasn't one for maintenance so call Vallient from the number on my app. Vallient were not sure if I was covered for a call out so booked me an engineer for the following day and took a card number for 90 pounds call out. I asked them if they wanted the error code from the boiler and was told it wasn't necessary. I CALLED northern Gas again and connected with the service booking option, I spoke with a lovely young lady - Sunita who quickly confirmed that she could help me. I advised her of the situation so far and she advised that when I call in the future I should always choose option one and there will be someone to help. She asked me the error code and promptly advised that she could resolve my issue by giving me instructions over the phone, we had my boiler up and running in minutes! Fantastic. She also stated that she would cancel my appointment with Vallient and also raise a complaint as the advise from Vallient was incorrect. I received an e-mail from Sunita confirming the appointment had beed cancelled. Sunita you are an angel! No heating is bad enough but no hot water is unthinkable and you saved my day, making me a very happy lady. Many thanks. Kelly
