First Utility were a very good provider! Until they were acquired by Shell Energy. Since they were taken over the standard of service has dropped signficantly. Shell Energy use underhand tactics to prevent customers being able to access their online services by denying access (suggesting PW was wrong when it wasn't) and basically deceiving customers at renewal time by deceptively switching the rates on the tariff but you have to be sharp to notice. But, if you don't you'll find yourself paying over-the-odds on the basis of their 'adjusted' tariff without realising it! It is a clever scam and no doubt a lot of their customers do not spot it. I believe that First Utility were perfectly trustworthy and it is very disappointing they sold the business to Shell. So, the star rating applies to SHELL and not First Utility who I would have had no hesitation giving FIVE STARS.
