About Hallidays Hydropower

Henry Reily-Collins brings engineering expertise to the technical arm of the Hallidays Group – Hallidays Hydropower. Henry gained his Masters Degree with Honours in Engineering, and was awarded the prestigious Worshipful Company of Ironmongers prize for his research.

Having joined the family Company, Henry became lead engineer on the £3M ‘eco’ refurbishment of Grade II listed Dandridge’s Mill in Oxfordshire. The project won countless awards for its integrated renewables and energy solutions, along with awards for the sensitive restoration work carried out to the building. The whole scheme encapsulated superior, high-tech systems, integrated into the historic building fabric, with no detriment to the character of the property – setting a precedent for low energy restorations of the UK’s historic building heritage.

Following the success of Dandridges Mill, Henry took the company’s project development experience together with his engineering skills to launch the technical branch of the group, Hallidays Hydropower, which recognises the potential of UK hydropower and addresses the need in the industry for ‘whole-project’ consultancy.

The team’s experience in property development has proved invaluable in working on a variety of complex projects and the company has gone from strength to strength. Recent projects, both national and international, have included installations for, among others, The National Trust and Blenheim Palace Estate. Henry’s passionate enthusiasm for hydropower and personal approach to each project has led the team to the forefront of this innovative technology.
