Solar for Hospitals
Round-the-clock demand and a need for resilience make healthcare sites strong candidates for solar and storage.
Hospitals and clinical buildings run continuously and can't afford unreliable power. Solar cuts daytime energy costs, and paired with storage it adds a layer of resilience.
We deliver it around live clinical operations, with the compliance the sector demands, as with our Greater Lancashire Hospital work.
Cornerstone Group installs solar PV across NHS hospitals, GP surgeries, hospices, care homes and private healthcare facilities throughout the UK: the highest-impact decarbonisation intervention for an NHS site, cutting bills and carbon with minimal disruption.
What’s included
The energy challenge for hospitals
NHS hospitals are among the highest energy consumers in the public sector, with electricity accounting for 40–50% of a Trust's Scope 2 emissions. An average hospital can save up to £45,000 a year through a correctly sized installation, with payback typically within 2–4 years and a 25-year-plus system life. More than 85% of NHS Trust Green Plans name solar PV as a priority.
Benefits
Protection against grid volatility and outages (with battery storage as an on-site buffer for critical systems); measurable progress against Net Zero and Green Plan obligations; revenue from surplus via the Smart Export Guarantee; and greater self-sufficiency.
Funding and process
Routes include the Public Sector Decarbonisation Scheme, Power Purchase Agreements and asset finance or leasing. We deliver site assessment and feasibility, power planning, smart infrastructure design integrated with complex hospital networks, installation around live clinical services, and commissioning and certification to BS 7671 with reporting-ready monitoring.

Hospital solar questions answered.
Can't see your question here? Our team is happy to talk it through.
Can solar be installed while clinical services stay running?
Yes. We install around live clinical services with the compliance the sector demands, as with our Greater Lancashire Hospital work, and design to integrate with complex hospital networks.
How much could a hospital save with solar?
An average hospital can save up to £45,000 a year through a correctly sized installation, with payback typically within two to four years and a system life of 25 years or more.
What funding routes are available for NHS solar?
Routes include the Public Sector Decarbonisation Scheme, Power Purchase Agreements and asset finance or leasing. We'll help you identify the right option for your site.
Can solar support critical systems during a power outage?
Paired with battery storage, solar provides an on-site buffer for critical systems, and we integrate it with your backup power.
How does solar help with our Green Plan and Net Zero obligations?
Solar cuts Scope 2 emissions and gives measurable progress against Net Zero and Green Plan obligations, and more than 85% of NHS Trust Green Plans name it as a priority. Our reporting-ready monitoring helps you evidence the results.
