If you have any concerns whatsoever, take advice from someone who got into a right mess with last supplier, and get in touch with BULB with a meter reading. My previous supplier SSE never reminded me to check my statements or prompted me for meter readings, In two years I only ever had one email from them a bout anything! When my smart meter was installed I was shocked at how much my electricity was costing and my usage seemed way more than it should be . I left it thinking it would all work itself out but one day my usage was so ridiculous that I called them ,they told me that my account was in debt. By over a thousand pounds. I was only paying £40 pcm and my useage was £ 175 minimum. No one told me, no one increased my monthly direct debits and after I got in touch I realised they had put me economy 7 tariff where day time electricity is almost twice the night time tariff. I dont have economy 7 and am at home all day with a disabled child who needs hot water and heating on all day. To clear the arrears my my DDs increased to £260 pcm . It was furious that they allowed this to happen. They should have at least knickend off the extra charges caused by their incorrect tariff, it they refused and after a few months I switched to BUKB. SSE took a final,payment to clear my account when I left of £675 without telling me ,leaving me overdrawn at the bank and with bank charges to,lay on top. All this. Happened because I didn’t submittb meter readings or keep my eye on the.ball. .Had I done soI would have seen that my tariff was wrong, my payments were insufficient and I was accruing a huge debt. NOW I log into my BULB account every week and submit readings as often as they’ll accept them. Never ,let things slide, for peace of mind get in touch, They won’t mind and you won’t worry or get in the mess I did.
