Holiday Parks, Home Parks, Caravan Parks and Marinas

With the rising cost of energy, our clients understand the necessity of managing their park and marina’s usage.

With pre-booked pitches and pontoons for the 2023 season and energy contracts coming to an end, park operators and marina management teams can no longer subsidise the cost of electricity and utilities for their clients.

Rather than hiking up pitch and mooring fees, the most cost-effective way to manage energy use is by implementing a metering system.
