Solar panels for care homes — FAQs

Typical 30–50 bed home: £24,000–£50,000 installed for a 30–50 kWp system. 60–100 bed home: £50,000–£100,000 for 60–100 kWp. Retirement village or care village: £150,000–£600,000 for 200–800 kWp. Cost per kWp falls from ~£950 below 30 kWp to ~£700 above 200 kWp. Capital allowances (AIA / 50% FYA) reduce effective cost by 12.5–25% for tax-paying operators.

Typical payback 3–6 years. Spirit Energy's Osbourne Court installation (52.65 kWp, B&M Care, April 2025) reported 5-year payback with 24% IRR. St Luke's (132.9 kWp) and St Leonard's (70.53 kWp) reported 6-year paybacks with 20–21% IRR. Strong 24/7 self-consumption (40–60% annual, 80–90% in summer) is the key to fast payback in this sector.

Industry benchmark is 40–60% off your annual electricity bill. For a 50-bed home spending £50,000/year on energy, that's £20,000–£30,000 annual saving from year one. Plus Smart Export Guarantee income on the 40–60% exported portion — typically £400–£1,500/year. A small home with £18,000 annual electricity bill typically saves £7,000–£10,000 a year.

Yes. The CQC Single Assessment Framework (2023) under the Well-led key question explicitly references environmental sustainability and responsible resource use as factors in Outstanding grading. Several Outstanding-rated home reports cite live generation displays and visible sustainability commitment. Solar does not directly improve Safe or Caring scores — but it strengthens the Well-led evidence base.

SECR (Streamlined Energy & Carbon Reporting) applies to companies with >250 staff or >£36m turnover or >£18m balance sheet — covering most major care groups (HC-One, Barchester, Bupa, Care UK, Avery, MHA, Anchor). Solar generation reduces purchased electricity (Scope 2) and is reported as an intensity metric in the annual Directors' Report. Strong year-on-year reductions improve ESG investor scoring.

Usually no — permitted development under Class A Part 14 GPDO 2015 covers rooftop PV up to 1 MW. Exceptions: listed buildings (LBC required), conservation areas (Article 4 Direction may apply), ground-mount over 50 kW (full planning), or any installation visibly affecting a roof slope facing a highway in some conservation areas. We handle all planning checks as part of pre-install survey.

Often yes, with Listed Building Consent. Approach depends on grade and visibility — Grade I and II* sites typically need ground-mount or canopy alternatives; Grade II sites often achieve consent for non-public-facing roof slopes with sympathetic flashing details. We've delivered installs on Grade II Victorian conversions — typical timeline adds 12–16 weeks for LBC vs unlisted.

Common on pre-1980 conversions and outbuildings. A pre-install asbestos survey is mandatory (HSE Control of Asbestos Regulations 2012). Three options: (1) install over non-friable asbestos using clamp fixings — viable for low-risk corrugated cement; (2) encapsulate then install; (3) replace roof and install simultaneously — often funded together. Typical additional cost £8k–£30k depending on area and disposal.

With proper specification, yes. We recommend LFP (lithium iron phosphate) chemistry — significantly lower thermal-runaway risk than NMC. Batteries are sited in fire-rated external plant rooms or dedicated containers away from resident accommodation. BS EN 62619 and IEC 63056 compliance. Fire detection and suppression specified to insurer's requirements. We integrate the system into your existing PEEP (Personal Emergency Evacuation Plan) framework.

From signed quote to commissioning: typically 12–20 weeks. Survey and design: 2–3 weeks. DNO G99 application: 4–12 weeks (parallel-tracked with install prep). Physical install: 5–15 working days on site. Commissioning: 1 week. Most install activity happens during daytime working hours, scheduled around mealtimes and medication rounds. No overnight working without prior agreement.

Minimally. Rooftop work happens above the building and is not visible or audible to most residents. Scaffolding and access equipment is shielded with privacy screens where dementia residents are present. We brief care staff and the registered manager before mobilisation. The only loud activity is roof penetration / clamping (typically 2–4 hours per phase) — scheduled outside quiet times.

Yes — modern panels generate on diffuse light, not just direct sun. UK rooftop systems typically generate 850–1,000 kWh per kWp per year. For a 50 kWp system that's 42,500–50,000 kWh annually. Output peaks in summer (typically 65% of annual yield April–September) and dips in December–January, matching care home electricity demand profile reasonably well.

Yes — solar is fixed plant and transfers with the freehold or long leasehold. For PPA contracts, the PPA novates to the new owner (subject to credit check) or is bought out at fair market value. For owned systems, MCS certification and warranties transfer. SEG account transfers to the new account-holder. Solar PV typically adds 4–8% to commercial property valuation per RICS guidance.

Yes — solar PV qualifies for AIA (£1m annual limit) at 100% first-year relief, or for the 50% First Year Allowance on special-rate pool (permanent from April 2026). For a £50,000 system, a corporation-tax-paying care company saves £12,500 immediately. Charities can access via trading subsidiaries. Always confirm with your accountant — we provide the depreciation schedule.

Yes — every building insurer requires notification of solar installation and a copy of the system spec sheet (kWp, panel make, inverter, battery if installed, install certification). Policy premiums typically rise £0–£200/year for small commercial PV. For large systems with battery storage, expect insurer-led fire risk assessment. We provide all documentation insurers ask for.

Solar PV adds new considerations to the Fire Risk Assessment under the Regulatory Reform (Fire Safety) Order 2005. DC isolators must be located at the inverter (BS 7671 standard) and a firefighter-accessible DC shutdown at ground level. Battery storage is the bigger consideration — sited externally with full FRA review. We provide an FRA addendum covering the installed system for your records.

A standard grid-tied solar system shuts down during a grid outage (G99 anti-islanding requirement). For backup during outages, you need battery storage with a backup-circuit capability — this can power critical-load circuits (call systems, emergency lighting, refrigeration, medical equipment) for 4–24 hours depending on battery size. We design backup circuits with the registered manager.

Yes — and increasingly recommended for care homes. Solar offsets the electricity heat pumps consume; heat pumps electrify your heating and hot water (currently mostly gas). Combined system typically targets full electrification of building energy. SHDF Wave 2.2 actively funds combined applications for social housing care schemes. Combined capex £80k–£300k for a 50-bed home; payback 6–10 years.

Low. Annual visual inspection and electrical compliance check — typically £350–£600 for a 50 kWp system. Inverter replacement after 12–15 years (£3,000–£6,000). Panels guaranteed 25–30 years with linear performance warranty (80%+ output at year 25). Battery: 10–15 year design life with cell-level monitoring. We offer annual maintenance contracts and remote monitoring as standard.

Yes — solar makes EV charging materially cheaper. A 22 kW workplace charger powered by solar costs around 3p–8p/kWh delivered (vs 25p–30p public charging). Care homes installing 2–6 chargers see staff retention benefits and a marketing edge for visiting families. The Workplace Charging Scheme grant (£350/socket up to 40 sockets) helps fund install.

Three main routes: (1) Power Purchase Agreement — no capex, pay per kWh at below-grid rate, 15–25 year term; (2) Operating lease — no capex, fixed monthly cost, 7–10 year term; (3) Asset finance / hire purchase — own the asset from day one, finance the capex over 5–7 years. We model all three and present the option that best fits your cashflow.

No — confirmed Spring Budget 2023, 100% business rates exemption for eligible commercial solar PV up to 5 MW until 31 March 2035. The valuation office should classify your PV as exempt plant on installation. We provide the documentation needed to confirm exemption with your billing authority.

Direct credit under SECR Scope 2 (purchased electricity). Indirect support for CQC Well-led KLOE evidence. ESG investor reporting credit under TCFD-aligned disclosures (group operators). Local authority commissioning credit where the LA scores sustainability in tender — increasingly common. Many care groups now include solar generation in their annual sustainability report.

Yes — and we encourage it. Family-facing comms (newsletters, website, open days, dementia-friendly visual displays) regularly highlight solar as a tangible sustainability commitment. Live generation displays in reception are a popular addition (£300–£800 per screen). Press release support and case study photography included in install package.

Best practice yes, regulatory no. Most homes notify residents and families 2–4 weeks before mobilisation via newsletter or quarterly comms. Resident meetings can include a brief explanation. Dementia residents may need additional reassurance about scaffolding noise — we offer a dementia-friendly site induction for our installers covering quiet-working protocols.

SHDF Wave 2.2 is administered by Salix Finance on behalf of DESNZ. Applications open in annual rounds — Wave 2.2 round 1 closed February 2025; round 2 expected Q4 2026. Eligible: registered providers of social housing with sheltered, extra-care or supported-living stock. We write the energy-savings modelling (PVSyst + SAP) and the application narrative on behalf of the RP.

Yes — hospices are excellent solar candidates and several have led the sector (St Michael's Hospice 60.2 kWp, St Peter's Hospice 25 kWp, both 2024 installs). Capex routes: gift-aided donor appeal, restricted-fund capital grants, charity trading subsidiary AIA, or PPA if no capex appetite. Gift Aid implications and restricted fund tracking handled in financial reporting.

Cleanly. CHP runs on gas / oil and provides heat plus electricity; solar provides electricity from sunlight. Typical care home with CHP: solar covers daytime electricity, CHP carries night and winter peak heat-led load. Battery storage smooths the handover. We model the integrated dispatch curve to confirm CHP runtime hours reduce (extending service life) without compromising heat output.

Panels: 25–30 year linear performance warranty (typically 84.95% at year 25) plus 10–15 year product warranty. Inverters: 5–10 year manufacturer warranty, extendable to 20 years. Battery: 10 year capacity warranty. Installation workmanship: 5–10 year SEO Dons workmanship guarantee. RECC consumer code protection for any consumer elements. We hold all warranty paperwork on your behalf.

Yes — design with capacity headroom. We typically specify inverters with 10–25% expansion capacity and panel-string layouts that allow easy addition. G99 amendment with the DNO is a 4–8 week process for a small expansion. Battery capacity is also expandable in modular systems (we recommend modular by default for care homes).

Yes for SEG eligibility and for many grant routes (including SHDF). We are MCS certified for commercial installations and follow the MCS commercial standard MIS 3002. NICEIC for electrical compliance. RECC and TrustMark for consumer-facing protections where any element is consumer-supplied (rare in commercial care). MCS certificate provided as part of handover pack.
