Love Bulb, after previously only ever using the most expensive company , I was pleasantly surprised. The tariff costs are less, the app is great , you can input the amount directly only app which you want to pay for DD and this is great as I don’t want to overpay as my usage is minimal. Plus it is so easy to get through to a real life human, as opposed to many options and call waiting and drop calls. I would recommend bulb!
