In recent years, there has been a growing trend of converting commercial spaces into residential units. This innovative approach not only maximizes the use of existing buildings but also contributes to the development of sustainable communities. In this blog, we will explore the upgrade renovations to six flats and three offices, with a focus on achieving Energy Performance Certificate (EPC) A ratings. We will delve into the installation of solar panels, the integration of a Smart iHelios heating system, and the implementation of home automation for enhanced energy efficiency and convenience.

  1. Evaluating the Existing Space: Before embarking on the transformation, it is essential to conduct a thorough evaluation of the commercial building. Assess the structural integrity, space layout, natural lighting, and ventilation options. This evaluation will help determine the feasibility of the renovations and identify areas for improvement.
  2. Energy Performance Certificate (EPC) A: To ensure energy efficiency, strive for an EPC A rating. This certification indicates that the building meets the highest standards of energy performance. Consider engaging a certified energy assessor to conduct an assessment and recommend energy-saving measures.
  3. Solar Panel Installation: Harnessing the power of the sun is a key component of sustainable living. Install solar panels on the rooftop to generate renewable energy for the residential units. This not only reduces dependency on conventional energy sources but also lowers utility bills. Seek professional advice to determine the optimum number and placement of solar panels for maximum efficiency.
  4. Smart iHelios Heating System: Upgrade the heating system to a smart iHelios system, which combines advanced technology with energy efficiency. The iHelios system allows for precise temperature control in each residential unit, reducing energy wastage and optimizing comfort levels. Its smart capabilities enable remote control and scheduling, ensuring efficient heating while minimizing energy consumption.
  5. Home Automation: Implementing a home automation system enhances energy efficiency and convenience for residents. Integrate smart devices, such as smart lighting, thermostats, and energy monitoring systems, to automate and optimize energy usage. Residents can control these devices remotely, ensuring a comfortable living environment while minimizing energy waste. The iHelios system's occupancy control feature allows for precise temperature control in each office space based on occupancy patterns. By detecting and adjusting heating levels according to occupancy, unnecessary energy consumption is minimized when spaces are unoccupied. This intelligent control system ensures that energy is only utilized when needed, resulting in substantial cost reductions.
  6. Insulation and Ventilation: To achieve an EPC A rating, prioritize insulation and ventilation upgrades. Enhance insulation in walls, floors, and roofs to prevent heat loss during the colder months. Install energy-efficient windows and doors to minimize drafts. Furthermore, consider implementing a mechanical ventilation system with heat recovery to maintain indoor air quality while conserving energy.
  7. Sustainable Materials and Finishes: When renovating the flats and offices, opt for sustainable materials and finishes. Choose eco-friendly flooring, low VOC paints, and energy-efficient appliances. Incorporate recycled or upcycled materials wherever possible to reduce the project's environmental footprint and create a unique aesthetic.


Following the renovation, the heating costs have been significantly reduced. During the winter months, the average monthly heating expenses have been reduced to approximately £600, representing huge  reduction compared to the previous system. The iHelios system's occupancy control ensures that heating is optimized according to office occupancy, eliminating wasteful energy consumption.

Moreover, during the summer months. As a result, the better solar panel performance costs have been reduced to a mere £30 per month, representing an approximate 80% reduction compared to the previous expenses.

The successful reduction of electric bills costs from £16,000 per year to £4,500 demonstrates the immense financial benefits of upgrading to the smart iHelios heating system. These cost savings, coupled with the enhanced energy efficiency and comfort provided by the occupancy control feature, make the iHelios system a valuable addition to the upgraded office spaces.

That's less than £40 per month per unit.

To conclude:

By combining the benefits solar panel installation, the iHelios heating system, and occupancy control, the upgrade renovations have not only achieved an Energy Performance Certificate (EPC) A rating but have also showcased the potential for energy-efficient transformations in commercial-to-residential projects. The significant cost savings and environmental benefits serve as a testament to the advantages of investing in sustainable technologies and practices for a greener and more efficient future.
