Glide's monthly payment plans are based on our experience and the usage the data we have at Glide for shared properties.
For example an 8 bed student house would be quoted to use more energy than a 3 bed house share.
Remember, you only pay for what you use. So, at the end of your tenancy, if you haven't used all the energy you've paid for, you may be due a refund. Likewise, if you use more, you may have a final balance to pay.
So keep those readings updated on your portal so you can track your consumption on your usage graph!
