The short version.
Running gyms 24 hours a day means heavy energy use. The Gym Group wanted to cut it without affecting members.
Voltage optimisation units were installed across 223 sites nationwide.
Across 223 sites the units have saved 4,485,763 kWh, £942,010 and 928,777 kg of carbon to date, a 7.85% average saving.
Advancing Sustainability through Voltage Optimisation
Background
The Gym Group is one of the UK’s largest gym chains, serving 820,000 customers across over 200 locations nationwide, operating 24 hours a day. Demonstrating a strong commitment to sustainable practices, The Gym Group became the UK’s first carbon-neutral gym and has set ambitious targets to achieve net-zero emissions by 2045.


Challenge
Operating numerous facilities around the clock presents significant energy consumption challenges. The Gym Group sought to enhance energy efficiency across its estate without compromising the quality of services provided to its members. The objective was to identify and implement solutions that would reduce energy usage, lower carbon emissions, and contribute to their sustainability goals.
Solutions
The Gym Group partnered worked with Powerhub Solutions to implement Voltage Optimisation (VO) technology across multiple sites nationwide. This technology reduces mains voltage to optimal levels, thereby decreasing energy consumption and enhancing the efficiency of electrical equipment. Specifically, the initiative involved the installation of VO units across 223 sites.
Results
The deployment of Voltage Optimisation technology resulted in substantial benefits:
- Energy savings: the VO units have saved 4,485,763 kWh across the estate since installation.
- Cost savings: £942,010 saved since installation, with an average unit saving of 7.85%.
- Carbon reduction: 928,777 kg of carbon emissions avoided, contributing to The Gym Group’s sustainability goals.
- Return on Investment (ROI): The project achieved a ROI within 18 months, underscoring the financial viability of the energy efficiency measures implemented.

Conclusion
By integrating Voltage Optimisation technology into its energy strategy, The Gym Group has taken a proactive approach to reducing energy waste and enhancing operational efficiency. This investment has not only led to measurable cost savings but has also significantly reduced their carbon footprint, reinforcing their dedication to sustainability. The success of this initiative demonstrates the effectiveness of targeted energy management solutions in helping businesses balance financial performance with environmental responsibility.
