From Olympic-sized swimming pools to multi-screen cinemas and indoor ski slopes, today’s leisure facilities are among the most utility-intensive developments in the commercial property sector. Understanding these demands from the earliest planning stages is critical to delivering projects that perform both operationally and financially.

The Power Behind Performance

Swimming pools are particularly power-hungry. Heating systems, filtration pumps, UV treatment, climate control for pool halls, and ventilation systems run continuously. A 25-metre pool can consume 150-300 kWh daily just for water heating, with total facility electrical loads often exceeding 500 kW.

Fitness centres present their own challenges. Banks of treadmills, cross-trainers, and other electronic equipment create significant and variable electrical loads. Climate control is critical—exercising bodies generate substantial heat that HVAC systems must manage. Lighting, entertainment systems, saunas, and steam rooms add further demand.

Indoor sports halls require powerful lighting systems that meet competition standards, sophisticated ventilation to maintain air quality, and increasingly, LED displays and audiovisual systems for events and spectator engagement.

Entertainment venues like cinemas, bowling alleys, and trampoline parks combine heavy HVAC demands with specialist equipment. Cinema projection and sound systems, bowling lane machinery, and extensive lighting all contribute to substantial baseload electrical requirements.

Water Infrastructure

While electrical demand often dominates feasibility discussions, water infrastructure is equally critical for sports and leisure developments. Swimming pools require exceptional water quality and supply resilience. A typical leisure pool holds 500,000 to over 1 million litres. Even with recycling and filtration, make-up water requirements are substantial, and the supply must be continuous and reliable.

Changing facilities for potentially hundreds of users creates significant hot water demands. Showers, sinks, toilets, and laundry facilities require both high flow rates and adequate drainage capacity. Many sites require enhanced fire suppression systems. Large public venues need sprinkler coverage across extensive floor areas, requiring substantial water storage and pressure that existing mains may not provide without reinforcement.

Other Utility Considerations

Natural gas connections are essential for efficient heating in many leisure facilities, supporting pool water heating, large‑volume space heating, and domestic hot water systems with better operational economics than electrical alternatives. Larger sites increasingly use combined heat and power (CHP) systems, which generate both electricity and useful heat, but these require careful utility design to integrate with the electrical grid and comply with export restrictions.

Modern leisure facilities are also highly data‑driven, relying on robust telecommunications infrastructure to support booking systems, access control, payment processing, building management systems, and guest WiFi. Advanced building management systems that optimise energy use, monitor pool chemistry, control HVAC, and manage lighting across complex sites require reliable, high‑bandwidth data connections, with many operators now expecting fibre connectivity as standard.

Planning for Success

Successful sports and leisure developments begin with comprehensive utility feasibility studies that go beyond simple capacity checks. Developers need to understand:

• Peak and baseload electrical demands across different operational scenarios
• Water supply flow rates and storage requirements
• Gas infrastructure for heating and potential CHP systems
• Telecommunications needs for operational and customer-facing systems
• Phasing requirements and connection timescales
• Costs for connection, reinforcement, and ongoing consumption

The variation in utility requirements between different leisure uses means each project demands bespoke assessment. An indoor climbing centre has entirely different needs from an ice rink, yet both may occupy similar-sized buildings on similar sites.

At Connections2energy, we’ve delivered utility solutions for sports and leisure facilities across the UK, from community swimming pools to major entertainment complexes. Our experience spans the full range of leisure developments, giving us insight into the specific challenges these projects present.

Whether you’re developing a boutique fitness studio or a regional sports complex, getting the utility infrastructure right is fundamental to operational success. The performance your customers expect depends on the power, water, and connectivity infrastructure most of them will never see.
