Honeypot Lane Health Centre

Project Overview

Genfit completed a rooftop Solar PV installation at Honeypot Lane Health Centre for Central London Community Healthcare NHS Trust (CLCH).

The project involved the installation of a 23 kWp Solar PV system, designed to generate clean renewable electricity directly on site and help reduce the health centre’s reliance on grid-supplied energy.

With 46 solar panels installed across the rooftop, the system is expected to generate approximately 18.76 MWh of renewable electricity each year, supporting the site’s day-to-day energy demand while contributing to CLCH’s wider sustainability goals.

The installation is estimated to save around 3.63 tonnes of CO₂ emissions annually, equivalent to approximately 167 trees planted, helping reduce the environmental impact of the building and support a lower-carbon healthcare estate.
