Smart meters are being installed across the UK to automatically record energy usage. While smart meters provide usage readings to suppliers, they only provide value to customers if the data is accessible through software. Smart meters offer benefits like accurate billing without estimates, detailed usage reports to detect waste, consumption alarms, and multi-site reporting. Customers can choose to purchase smart meters outright or lease them for an annual fee, with leasing being the preferred option for most. The installation process involves gathering site details, signing contracts, and a typical 6-8 week installation timeframe. Once installed, customers get login details to access reports and manage their energy consumption online.
