Grants and funding for solar panels for care homes

Care home solar in the UK is rarely funded by capital alone. The standard playbook combines a route that defers or eliminates capex (PPA, lease, or asset finance), a tax-relief overlay (Annual Investment Allowance or 50% First Year Allowance) for tax-paying operators, and — where the home qualifies — a grant top-up. This page covers every route in 2026, the order to combine them in, and where the wins and pitfalls are.

The 2026 funding landscape for UK care homes

Care home solar funding hasn't changed dramatically in 2026, but two pieces of the puzzle are now permanent. First, the 100% business rates exemption for solar PV confirmed at Spring Budget 2023 is in force until 31 March 2035 — solar plant no longer triggers business rates uplifts on commercial property. Second, the 50% First Year Allowance (special-rate pool, for limited companies above the £1m AIA cap) became permanent from April 2026 — extending the accelerated tax-relief window for large group operators investing across portfolios.

Direct sector grants for care homes specifically remain narrow. Unlike NHS hospitals (PSDS Phase 4) or schools (Salix energy efficiency loans), independent and private-sector care homes don't have a dedicated national funding stream. What exists is fragmentary: SHDF Wave 2.2 for housing-association-owned sheltered and extra-care schemes, occasional LA commissioning premia for sustainability, and indirect tax shields. For most care homes, the math works because the underlying economics are strong — 3–6 year payback at scale — not because grants subsidise it.

Route 1 — Power Purchase Agreement (PPA): zero capex

For care home operators with limited capital or who'd rather invest into resident care, a PPA is the most common route in 2026. A third party owns, installs, and maintains the solar system. The care home buys the electricity it generates at a fixed per-kWh tariff — typically 8p–14p, locked for 15–25 years — versus a grid import rate now at 27p/kWh. Day one cashflow positive. No capex. No depreciation on the balance sheet.

Worked example: a 50-bed home with a 50 kWp PPA system at 11p/kWh generates 47,000 kWh annually, of which 24,000 kWh is self-consumed (priced at 11p PPA vs 27p grid = 16p saving × 24,000 = £3,840/year); 23,000 kWh is exported and the PPA provider keeps the SEG income. Net saving to the home: £3,840/year, year one, no capex. Over 20 years at modest tariff inflation: £85,000–£110,000 total saving.

PPAs work best when (a) you have 20+ years occupation security on the building, (b) the home is profitable and stable, and (c) you don't want the asset on your balance sheet. They work less well for charity hospices (gift-aid donor preferences usually favour visible capital ownership) and where the building may be sold within 7 years (PPA novation is possible but adds friction to a sale).

Route 2 — Capital purchase with AIA tax shield

For tax-paying care home companies with capital available, owning the system outright typically beats PPA on lifetime economics — but it requires the capex upfront. The Annual Investment Allowance provides 100% first-year capital relief on qualifying plant up to £1 million per company per year. Solar PV qualifies as general-pool plant. For a £50,000 system, that's a £12,500 corporation tax saving in year one at the 25% main rate — effectively a 25% capex discount.

Worked example: a £45,000 install on a 60-bed nursing home generates 42,000 kWh annually, 21,000 kWh self-consumed at 27p grid offset = £5,670 saving + 21,000 kWh exported at 7p SEG = £1,470 = £7,140 gross year-1 saving. AIA tax shield reduces effective capex to £33,750. Simple payback on the effective capex: 4.7 years. Over 25 years assuming 3% energy inflation: £280,000+ lifetime saving on a £33,750 net outlay.

Route 3 — 50% First Year Allowance (group operators)

For group operators spending more than £1m on solar across a single tax year — relevant for the largest groups rolling out across 10+ sites simultaneously — the 50% First Year Allowance applies to special-rate pool expenditure above the AIA cap. Half the spend gets immediate tax relief; the other half goes into the special-rate pool at 6% writing-down allowance per year.

Worked example: a national group invests £2.4m in solar across 22 sites in a tax year. £1m gets full AIA relief (£250k tax saved at 25%). Remaining £1.4m: 50% FYA = £700k immediate relief (£175k tax saved) + £700k into special-rate pool at 6% WDA. Total year-1 tax shield: £425k on £2.4m capex = 17.7% effective discount. Plus continuing WDA on the remaining pool for years to come.

Route 4 — Salix Social Housing Decarbonisation Fund Wave 2.2

If your scheme is sheltered housing, extra-care housing or supported-living stock owned by a registered provider of social housing (housing association or council), Salix-administered SHDF Wave 2.2 is the dominant grant route. Confirmed in the Autumn 2024 Budget at £1.29 billion over 2025–2028. Provides up to 50% match funding for fabric improvements, low-carbon heat, and on-site renewables — including solar where it offsets landlord-supplied communal electricity.

Eligibility is RP-only — private care home operators can't apply directly. But if your scheme is a partnership between a private care operator and a housing association landlord, the HA can apply on behalf of the scheme. We write the PVSyst / SAP energy savings modelling and the application narrative. Round 1 closed February 2025; Round 2 expected Q4 2026.

Route 5 — Smart Export Guarantee (SEG)

Every commercial solar installation up to 5 MW with a smart meter qualifies for SEG, paying for electricity exported to the grid. Tariffs vary by supplier — typically 5p–15p/kWh, with Octopus, E.ON, EDF and others competing. Care homes typically self-consume 40–60% of their generation, exporting the remainder. SEG income on the exported portion typically adds £400–£1,200/year to a 30–60 kWp system.

SEG is not a grant but a continuing income stream — and contributes to a faster simple payback. We register your installation with your chosen SEG supplier at commissioning.

Route 6 — Local authority commissioning premia

Local authorities that commission care home beds increasingly score sustainability in the procurement framework. Hampshire, Manchester, Devon, Surrey and a growing list of others have piloted sustainability premia on bed rates — typically £2–£10/bed/week uplift on LA-commissioned beds where the home demonstrates carbon-reduction action including renewables. For a 30-bed LA-commissioned home, that's £3,000–£15,000/year of additional revenue, layered on top of energy savings.

Check with your contracts officer at the next commissioning renewal. We provide the technical evidence pack (system spec, generation data, SECR-style CO₂ accounting) that LA contracts teams ask for.

Route 7 — Business rates exemption to 2035

Not a grant, but worth naming explicitly because it removes a historic cost barrier. Pre-April 2023, installing solar on commercial property could trigger a business rates uplift on the underlying premises — sometimes adding £10–£30/kW/year in rates. Spring Budget 2023 confirmed 100% business rates exemption for eligible commercial solar PV up to 5 MW. Confirmed in force until 31 March 2035.

The valuation office should classify your PV as exempt plant on installation. Occasionally a billing authority misses the update — we provide the documentation to confirm exemption directly with the VOA on request.

Route 8 — Care England / Focus Energy Solar Framework

A sector-endorsed buying route operated by Care England in partnership with Focus Energy Services. Free for care providers to access. Provides connections to vetted installers and independent energy specialists. Useful for boards and trustees who want a sector-body endorsement of the procurement route.

We're not on the framework, but we will benchmark our fixed-price proposal against any framework quote you obtain — and we'll be honest if the framework quote is genuinely better for your specific site.

How to stack funding routes

Most care homes use one funding route plus one tax overlay. Most common combinations in 2026:

• Private operator, single home, no capex appetite: PPA + SEG (auto-routed via PPA provider). Net effect: zero capex, £4,000–£8,000/yr saving from year one.
• Private operator, single home, capex available: Capital purchase + AIA + business rates exemption + SEG. Effective payback 3.5–5 years.
• Multi-site group, rolling annual programme: Capital purchase + AIA + 50% FYA on overflow + business rates exemption. 17–25% effective tax shield on annual programme.
• Housing-association sheltered/extra-care scheme: SHDF Wave 2.2 (50% grant) + remaining 50% capex + business rates exemption. Effective payback 3–4 years.
• Charity hospice: Gift-aid capital appeal + restricted-fund accounting + business rates exemption + SEG. Often donor-named installations.
• LA-commissioned home: Any route above + LA commissioning premium where authority operates one.

Common pitfalls and how to avoid them

• Not notifying your building insurer. Every install must be notified with system spec. Failure can invalidate your buildings cover. We provide the documentation.
• Assuming you can self-consume 100%. Annual self-consumption rates above 65% are unusual on care homes without battery storage. Realistic modelling is the difference between a 5-year and a 7-year payback.
• Skipping the asbestos survey on pre-1980 roofs. Discovering asbestos mid-install adds £8–£30k. Always survey first.
• PPA without buy-out clause. If you sell the home in year 8, a PPA without a clear buy-out mechanism complicates the sale. Insist on year-7+ buyout at fair market value.
• Battery chemistry choice. NMC batteries carry higher thermal-runaway risk than LFP. For vulnerable-occupant settings, specify LFP only — and insist your installer agrees in writing.
• Treating SHDF Wave 2.2 as a private-operator route. It's RP-only. Partner with your HA landlord or skip the route.
