Basically do a price comparison to find a good Eco 7 provider I always like EDF personally . Set up an arrangement with them , single person on Eco 7 I would imagine they ' ll take 20 30 a month off you . Give them regular meter readings and they will adjust your bill accordingly . As part of this process , the people you have yet to pay for electricity will send you a final bill potentially around the 100 mark but could be anything , you will also need to agree a repayment with them , either in one go or over time . If this is your first property I want to stress , keep on top of your meter readings . Nothing sucks more than thinking your payment of 30 per month is enough then getting a bill for 2000 when you move out .
