Extra-care housing — schemes with on-site 24/7 care providing both independent-living units and care services — is one of the fastest-growing parts of the UK social care landscape, and an excellent solar target. The combination of 24/7 care baseload, communal facility demand, and a frequently housing-association or LA-commissioned tenure mix makes extra-care eligible for SHDF Wave 2.2 grant funding plus LA commissioning premia.
Why extra-care suits solar
Extra-care schemes pull together the best features of sheltered housing (communal demand, RP ownership eligible for SHDF) and care homes (24/7 baseload, vulnerable residents justifying battery storage). A 60–100 unit extra-care scheme typically has 50–200 kWp of solar potential on the multi-block roofscape, drawing against a communal demand of 80,000–250,000 kWh/year. Self-consumption 55–70% annually.
Typical install
50–200 kWp solar + 50–200 kWh battery storage. Project value £40,000–£200,000. Annual generation 46,000–184,000 kWh. Annual saving £8,000–£35,000 on communal supply alone. Payback 5–6 years on capital, 3 years with SHDF 50% match.
SHDF + LA commissioning double layer
Extra-care is unusual in qualifying for both major funding overlays: SHDF Wave 2.2 (RP-eligible up to 50% match) and LA commissioning premia (where the LA commissions on-site care packages and operates a sustainability uplift). Combined effect: capital cost reduced by 50% (SHDF), revenue uplifted by £3,000–£15,000/year (LA premium), and energy savings of £8,000–£35,000/year. Net result: payback effectively under 3 years on the RP's residual capital outlay.
Battery storage and resident safety
Battery storage is more commonly justified on extra-care than on sheltered, because the on-site care service requires resilient power for call systems, lift access, medication fridges, and emergency lighting. We specify LFP chemistry only, sited externally in fire-rated plant rooms. Backup circuits sized for 6–12 hour critical-load coverage. FRA addendum and PEEP integration as standard.
LA commissioning contract integration
For extra-care schemes commissioned by a local authority, the install should be timed to align with contract renewal cycles. Sustainability scoring typically applies at retender; LA contracts officers want to see evidence of carbon reduction action including renewables. We provide the technical evidence pack — system spec, generation data, SECR-aligned CO₂ accounting, and 5-year carbon reduction trajectory — that LA teams ask for.
Multi-block scheme economics
Larger extra-care schemes (90+ units) typically span 3–6 buildings. We design solar across multiple roof slopes with phased install, allowing the RP to spread capital outlay across 2–3 financial years if needed. G99 application is typically scheme-wide rather than per-building, simplifying the DNO process.
Key features of extra care housing solar installs
Across the extra care housing sub-vertical, four patterns recur on the installs we deliver:
- 24/7 care on-site = strong baseload through staff base, hoists, communal kitchens
- Often LA-commissioned — sustainability scoring weighs heavily in retender
- Larger schemes (60–100 units) have flat-roof footprints suitable for 150–200 kW
- Battery storage adds resident-safety resilience and peak-shaving
Compliance and regulation for extra care housing
CQC-registered for on-site care. Tenancy mix (rental + leasehold + commissioned care packages) determines benefit flow. LA commissioning contracts increasingly require ESG/sustainability commitments — solar contributes.
Funding routes that work for extra care housing
Most extra care housing operators we engage with use one of three funding routes, often layered with a tax overlay where the corporate structure allows. The right combination depends on capital appetite, tax position, and ownership horizon:
- Power Purchase Agreement (PPA). Zero capex, day-one cashflow positive, 15–25 year fixed tariff typically 50–70% below grid. Best for operators preserving cash for resident care or capital projects. See our PPA guide.
- Capital purchase with AIA. 100% first-year tax relief on the full capex up to £1m. Effective 25% discount at main corporation tax rate. See capital allowances detail.
- Asset finance / hire purchase. Spread the capex over 5–7 years, often timed so monthly payments fall below energy savings by year 3. Own the asset from day one. See leasing detail.
For housing-association-owned schemes (sheltered, extra-care, supported living), the SHDF Wave 2.2 match-funding route adds a fourth option — up to 50% grant covering fabric + on-site renewables. All routes preserve the 100% business rates exemption on solar PV until 31 March 2035.
Why we specialise in extra care housing
Extra Care Housing solar installs share three operational requirements that generic commercial contractors often miss. First, scheduling around resident wellbeing — mealtimes, medication rounds, visiting hours, and (in dementia or hospice settings) acutely sensitive resident-facing protocols. Second, CQC-aligned documentation: registered managers need an evidence pack for the next inspection, and the right specification of equipment, signage, and reporting matters. Third, sector-appropriate safety specification — particularly where battery storage is included, where chemistry choice (LFP vs NMC) and external siting are non-negotiable for vulnerable-occupant settings.
Every extra care housing install we deliver follows a sector-specific protocol covering pre-install briefing, resident-facing communication template, dementia-friendly induction (where applicable), and CQC Well-led KLOE evidence-pack handover. The result is faster sign-off, cleaner CQC files, and — crucially — zero resident-facing incidents during the install period.
