    Wilson Consulting Limited

  • What Our Clients Say

    We employed Julia from 3CO Ltd to energy score our domestic dwelling and review the de-carbonisation processes that we had incorporated following its new build 17 years ago!

    Julia demonstrated excellent and thorough knowledge and surveyed the property, its fabric, and the HVAC assets in detail to provide an accurate energy score and subsequent report.

    The report was issued in a timely manner, and the communication process was seamless. The bonus of such a report for us with the approval off a Green Energy Mortgage with our local bank which was achievable following the investment made in our de-carbonation projects, specifically related to this property.

    We would recommend this to other property owners who would like to benefit from green energy mortgages.
