I am writing this review so that people understand how bad this company is. Through no fault of my own, when I moved property my new property had pre payment meters with Boost. There has been nothing but problems as the only way of topping up has been through their app and a lot of the time this hasn't worked. I eventually changed company to British Gas (brilliant company). On changing I had to go through the normal 28 day transmission period as the Law states. British Gas gave me all their details prior to this period , brilliant however Boost was a different story. From a month prior to the change over date. My App started to play up even though I was in credit and I have used more and more money as the so called smart meter hasn't updated so has shown a debit half the time. On change over day, Boost totally stopped me using their App meaning there was no way for me to top up even though for that period I should still have been able to top up (by law). Following several phone calls to them and British Gas, Boost was totally unhelpful saying I was no longer their customer and had been totally wiped from their system. So during this period even though I should have still been topping up through them I was unable to. Then to finish it off when British Gas tried to help me out it was found that the Boost smart meters that had been installed in the property 5 years previously had no key or card slot, basically meaning without persistence I could not change to another company without going without gas and electric for 28 days. Thankfully British gas have got an engineer out to me the same day as an emergency to change the meters over so that I can make payments. British Gas I would give more than 5 out of 5 if I could but Boost if I could give a score of 0 I would. Please please do not touch Boost energy company. They are disposable to deal with and basically make it near on impossible to change from them if you happen to be with them. Also even if in credit on your gas and electric they have problems with their payment methods and you can end up paying double. I am writing this review on behalf of a friend whom I have been helping with telephone calls for over 2 hours to get this mess sorted. Without the help of British Gas and knowing the Law myself. My friend and her young family would have no gas and electricity for the next 28 days and all because of going with Boost energy m she has never once been in debit on her account yet gets treated appallingly by this company. Do Not Touch. Please look to other companies. We are now going to report Boost to Ofgem.
