About Us

Acknowledging the growing number of infrastructure developments and the need for developers to engage more effectively with landowners, Blackhall & Powis commenced trading in 2017. The business was established to support energy and infrastructure providers to assemble rights in land and other consents for their projects. Over the years we have grown steadily to accommodate the demand. Now we are one of the few consultancies fully focused on representing developers and acquiring authorities.
