You should purchase this Loop monitoring kit if you don’t have a smart meter. If you do have a smart meter, you can link it to the Loop system and enjoy the benefits for free – no purchase required. Please note: You require access to your meter cupboard to fit the Loop Clip. The Loop service is only available via the Loop app (compatible with Apple iPhones from 5S onwards and with Android handsets running version 7 or later). There is no web version. We currently support mainland UK households only. See here for further compatibility information. This Loop Monitoring Kit is for households without a smart meter. On average Loop households cut their electricity usage by 10%.
