MHSL helps clients improve building efficiency through renewable energy, low-carbon technologies and practical mechanical and electrical upgrades. We work with building owners, occupiers and main contractors to integrate solutions that suit their premises, operational requirements and longer-term energy objectives.
Solar PV
We support the installation of solar photovoltaic (PV) systems that generate electricity for use within the building. Our approach considers electricity demand, available installation space and integration with the existing electrical infrastructure, helping clients make effective use of on-site generation.
EV Charging
We provide electric vehicle (EV) charging installations for workplaces, commercial premises and fleet parking areas. We consider charger locations, electrical capacity, anticipated usage and cable routes, with provision for load management and future expansion where appropriate.
Battery Storage
Battery storage can complement solar PV by storing generated electricity for use at other times. We help clients consider how storage could fit their building’s energy demand, existing systems and operating arrangements, including its potential to increase the use of on-site generation.
Low-Carbon Heating and Energy Efficiency
Our approach also includes suitable heat pump installations, energy-efficient lighting, improved heating and ventilation controls, and energy monitoring. Alongside new technology, we consider opportunities to improve existing systems through targeted equipment replacement, better controls and adjusted operating schedules.
Installation and Handover
We assess how proposed upgrades will work with the building’s existing mechanical and electrical services, taking account of capacity, access and maintenance requirements. Careful coordination, installation, testing and commissioning support effective operation, while clear handover information helps clients understand and manage their systems.
Whether delivering an individual EV charging installation or a coordinated programme of energy improvements, our focus is on practical solutions suited to the building and its users.
