Northern Gas are the worse company I have ever dealt with. They have been selling boilers to customers with the promise of a free 10 year warranty. When the boiler goes wrong there is a constant argument between NGH and vaillant as to which customers are still in warranty. NGH blame vaillant and vaillant blame northern gas. We the customer are left in the middle without heating or hot water. No one in customer service goes over and above to help. They just fob you off. They want the customer to be tooing and froing between the 2 customers. This problem between directors should have been sorted out years ago. Same problem in 2021 which took 3 weeks to sort out. The customer should absolutely come first. I was promised a call back by the end of today. Its 7pm and I am still waiting. I have no alternative but to speak to Ofgem next week and hope I get somewhere.
