“I recently engaged Octopus for a solar installation and am very pleased with the professionalism of the team involved.

From the outset, Solar Specialist Muhammad Lodhi provided invaluable support. His strong technical knowledge and clear advice were key in guiding the design stage. When unforeseen challenges arose with the BVT, requiring amendments to the system layout and panel numbers, Muhammad acted promptly and efficiently to revise the design, ensuring everything remained on track. He was always there to answer queries.

During the installation phase, Smart Tech Specialist Victor Chukwu coordinated the process with great efficiency. He was consistently available to address queries, provided timely updates, and ensured smooth communication throughout

Finally, Elais, the electrician, carried out the installation work to an excellent standard. He was courteous, professional, and meticulous, completing the job with care and leaving the property in immaculate condition.“
