Trewithen House is an historic, privately-owned Cornish estate with beautiful gardens, famous for their plant hunter origins, royal connections and astonishing variety of species. Trewithen House is an architectural gem that has not significantly changed its outward appearance since the mid 1700s.  The award winning estate opens its house and gardens to the public and runs a busy nursery, tea shop and gift shop on site.

CleanEarth was contracted to install solar PV and biomass heating for the estate, managing and undertaking all aspects of both installations, including negotiating the challenging planning, conservation and heritage restrictions associated with such important Grade I listed buildings and Grade II registered park and gardens.

We managed the project with sympathy to the history of the estate, installing the systems without impacting the premises visually.  We installed the roof mounted solar on an agricultural building on the estate and we built a special boiler house for the fuel storage and biomass system.

The biomass system meets 100% of the estate’s heating needs including the main house, offices, workers’ cottage and indoor swimming pool.

What the Client Said

CleanEarth were excellent throughout the process of installing both the solar array and the biomass boiler. They explained everything thoroughly prior to both schemes proceeding and were neat and tidy during the construction process. They were an extremely efficient team to work with - James Humphreys, of Smiths Gore, who manages the Trewithen Estate.
