  • Noel McDonald

    I’m very satisfied with the installation recently completed by Impact Services. The installation team was very efficient, and each technician was very personable. The work was completed on schedule and the men were helpful, friendly, and informative. They tidied up thoroughly afterwards. Excellent work overall!

    Nothing but praise for the team at Impact Services this week. We are pleased to say we started reaping the benefits of solar panel electricity within hours of installation. We were recommended Impact Services by a friend and would recommend them to anyone else looking to install Solar Panels. You won’t be disappointed.
  • John Fraser

    Electricians arrived at 8:30 and installed the inverter and batteries by 11:30. The solar panels installation then arrived and by 16:30 they had fitted and connected the 8 panels. Great job done! All clean and tidy – most professional job done by the team from Impact Services. I would recommend them without hesitation.
