Application

Saving Money

Pipit’s touchscreen display allows tenants to view their energy usage in real-time, and their consumption history for the previous twelve months.

Saving energy

Visibility of energy consumption means that tenants can make informed choices about their energy use. Reducing energy consumption in order to save money naturally has a positive effect on long-term energy waste. It’s an eco-step in the right direction.

Saving Time

We like to keep things simple, and our smart pre-payment energy solution combines simplicity with effectiveness. Topping up couldn’t be easier for tenants, with our range of pay-as-you-go offerings. They can top-up at a retail outlet, or from the comfort of their own home online, via text or over the phone.
