Solar Panels for Hospitals — FAQs
Direct answers with real numbers, updated for 2026.
These are the questions that come up in real conversations with NHS estates directors, sustainability leads, facilities heads, and private hospital operations teams — not a generic solar FAQ with the word "hospital" inserted. They cover the money (costs, PSDS Phase 4, Salix loans), the governance (Trust Board approval, PFI contracts, procurement frameworks), and the clinical-environment questions that only matter in healthcare: HTM 03-01 infection control during installation, HTM 06-01 electrical compliance, medical equipment interference, and DBS clearance for installers in patient areas. Where a question deserves a longer answer, we have linked the page that gives it. If your question is not here, ask us directly — unanswered questions usually become the next entry on this page.
How much do solar panels for a hospital cost in the UK?
Acute hospitals (300 kW–2 MW): £250,000–£1.6m. Community hospitals (100–500 kW): £90,000–£450,000. Mental health units (100–400 kW): £90,000–£360,000. GP surgeries and primary care (20–80 kW): £22,000–£90,000. Cost per kW typically £750–£950 above 250 kW, falling to £700/kW at acute scale.
What grants are available for NHS solar?
Public Sector Decarbonisation Scheme (PSDS) Phase 4 — primary route, NHS-allocated funding, often 100% capital grant for combined heat pump + solar schemes. Salix Decarbonisation Loan — interest-free for smaller projects. NHS estates operational capital — Trust-level funding. Combined, most NHS solar is delivered with little or no Trust capital outlay.
How does solar fit with NHS Net Zero by 2040?
Directly. NHS Net Zero target is 80% reduction by 2032 vs 1990 baseline, full net zero by 2040. Greener NHS Plan requires every Trust to publish a Green Plan including specific renewable energy commitments. Solar is the single largest action available for most Trusts. Auditable through ERIC reporting.
Can we install solar on a PFI hospital?
Yes, but the contract structure matters. If the PFI partner pays the energy bill, savings flow to them — install economics depend on whether they're co-investing or share savings with the Trust. Increasingly, PFI partners are co-investing under renegotiated VFM arrangements. We've worked through both structures.
How do we maintain operational continuity during install?
Roof installation happens above operations — wards, theatres, ITU continue normally. We follow HTM 03-01 infection control protocols. The only operational touchpoint is final grid connection (4–8 hours), scheduled with Trust Estates and theatre management for a planned window. We've delivered acute hospital installs during normal operations.
What about infection control during install?
HTM 03-01 (Infection Control in the Built Environment) applies. Contractors are inducted by Estates and IPC teams. Construction zones segregated from clinical areas. Negative-pressure zones maintained where applicable. PPE protocols. We've delivered installs in immunocompromised patient zones with zero infection-control incidents.
Will solar interfere with medical equipment?
No. Modern grid-tied PV inverters comply with EN 50549 and produce clean sine-wave output indistinguishable from grid supply. We follow HTM 06-01 electrical services standards and obtain Authorising Engineer (Electrical) AE(E) sign-off as standard. EMC compliance verified for sensitive equipment areas.
Do installers need DBS clearance for hospital sites?
For patient-area access, yes — Enhanced DBS plus relevant Barred Lists. We maintain DBS clearance for our entire commercial install workforce. Mental health sites require additional safeguarding awareness. Children's hospitals require Children's Barred List checks.
How long does an NHS hospital install take?
From PSDS award to commissioning: 12–24 months. PSDS application: 4–6 months. Procurement (typically frameworks): 8–16 weeks. Physical install: 6–20 weeks for 300 kW–2 MW systems. Commissioning and integration: 4–8 weeks. Total NHS solar projects typically 18–36 months from conception to commissioning.
Can we use NHS frameworks for procurement?
Yes — and recommended. Crown Commercial Service Decarbonisation Framework (DPS), NHS Shared Business Services Construction Consultancy framework, ESPO framework all include solar specialists. We're listed on multiple frameworks and can deliver via direct award or mini-competition.
What's the impact on ERIC reporting?
Positive — ERIC tracks energy use intensity (kWh/m²) and CO2 emissions intensity. Solar reduces both. Solar generation is reported separately under the Greener NHS Green Plan annual return. Strong ERIC performance correlates with Trust Board confidence and CQC well-led judgements.
Can we combine solar with heat pumps for whole-estate decarbonisation?
Yes — and PSDS Phase 4 actively rewards combined applications. Heat pump + PV is the most common NHS decarbonisation approach. Heat pumps electrify heating (currently gas/oil); PV supplies the displaced electricity at near-zero marginal cost. Combined, capital is in the £2–10m range per Trust site, typically 80–100% PSDS-funded.
