Portsmouth Care Home Solar Installations
Portsmouth care home operators across Hampshire — including Gosport, Fareham, Havant — installing MCS-certified rooftop solar with 4–6 year payback. For the UK-wide overview, see our main solar panels for care homes UK guide.
Solar panels for care homes in Portsmouth
Portsmouth is home to an estimated 75 registered care homes, serving the city’s ageing population alongside surrounding Hampshire. The city’s care sector spans the full range — small family-owned residential homes, large group-operator nursing homes from Care South, Colten Care and Bupa, sheltered housing schemes run by registered providers, and an increasing number of dementia-specialist units serving residents whose families live across South East. The combined sector consumes a substantial slice of Portsmouth’s commercial electricity load: a typical 50-bed home in Portsmouth now spends £40,000–£62,000 annually on gas and electricity, up from £19,000–£28,000 in 2019.
Portsmouth City Council operates under the Portsmouth Climate Emergency Plan with a 2030 net zero target — 12 years ahead of the national 2050 statutory deadline. Solent Freeport status applicable. Naval and defence supply chain represents major commercial energy concentration. For Portsmouth care home operators, that means strong council planning support for rooftop PV, an established local supply chain of MCS-certified contractors, and increasingly visible peer activity to draw on — from Care South sites to independent operators publishing live generation displays in their reception areas.
Why Portsmouth care homes are particularly well-suited to solar
The economics of care home solar in Portsmouth are unusually strong, for three reasons specific to the city:
1. Sunshine hours are higher than people assume. Portsmouth averages 1,750 hours of sunshine per year — enough for a UK-orientated PV array to generate approximately 1,838 kWh per installed kWp. A typical 45 kWp system on a Portsmouth care home will produce around 83,000 kWh annually, which at a 50% self-consumption rate (typical for a 24/7 care setting) covers roughly 40–55% of the home’s annual electricity demand.
2. Care home demand profiles match generation profiles. Unlike offices (closed at night and weekends) or retail (peak demand in evenings), care homes operate 24 hours a day, 365 days a year. The hot water, laundry, lift systems, call buttons, kitchen equipment and lighting that drives a care home’s electricity bill peaks during daylight hours when solar is generating. Self-consumption rates of 40–60% annually are typical, rising to 80–90% in summer months. Every kWh self-consumed saves the full 27p import tariff rather than the 5p–15p Smart Export Guarantee rate.
3. Portsmouth’s commercial electricity prices have compounded the case. Industrial electricity in the UK rose 113% in real terms between 2019 and 2024, and Portsmouth is no exception. With business electricity at 27p/kWh in 2026 and Ofgem’s State of the Market Report 2024 forecasting continued upward pressure, the marginal saving from each generated kWh is substantial. A 45 kWp install at a Portsmouth care home now typically saves £6,500–£9,800 annually from year one — comfortably ahead of the £30,000–£40,000 capital cost on a five-year payback.

Planning, grid connection and council policy in Portsmouth
For most Portsmouth care homes, rooftop solar falls under permitted development rights (Class A Part 14 GPDO 2015), meaning no planning application is required. Exceptions are listed buildings (Listed Building Consent), Article 4 Direction areas (council notification required), and any installation that materially affects a roof slope facing a public highway in a conservation area. Portsmouth City Council typically responds to planning pre-application queries within 6–8 weeks.
Grid connection is handled under the G98/G99 frameworks. Portsmouth is served by National Grid Electricity Distribution as the local Distribution Network Operator. Typical timescales for a 30–80 kWp G99 application are 4–12 weeks, depending on local capacity. For larger installs above 100 kWp on retirement villages or care villages, expect 3–6 months.
Care home group operators active in Portsmouth
The city has a mix of national group operators and locally-rooted independents:
- Care South — operates multiple sites across Portsmouth and Hampshire
- Colten Care — operates multiple sites across Portsmouth and Hampshire
- Bupa — operates multiple sites across Portsmouth and Hampshire
- Anchor — operates multiple sites across Portsmouth and Hampshire
- Plus an estimated 60–80% of the 75 estimated homes are independently owned or operated by smaller regional groups
For larger group operators with multiple Portsmouth sites, we structure portfolio-level procurement to capture volume pricing, standardised G99 templates with the DNO, and a coordinated rollout programme — typically completing all sites within a single calendar year.
Sub-vertical breakdown for Portsmouth
Portsmouth’s care home estate breaks down approximately as follows:
- Residential care homes (40–55% of stock): 30–60 kWp typical install, hot water + laundry-led demand
- Nursing homes (20–25%): 40–80 kWp typical, higher baseload from medical equipment
- Dementia care units (15–20%): often co-located with nursing; 40–90 kWp; battery storage strongly recommended
- Sheltered housing schemes (8–12%): communal-area installs of 20–100 kWp; SHDF Wave 2.2 eligible if housing-association owned
- Extra-care housing (5–8%): 50–200 kWp on multi-block estates; LA commissioning contracts often score sustainability
- Hospices (2–4%): charity-funded; 25–80 kWp; gift-aided capital appeals are the dominant funding route
- Retirement villages and care villages (1–2%): 100–800 kWp; EV charging integration high-value

Local funding routes for Portsmouth care homes
The standard funding routes apply: PPA (zero capex, 8–14p/kWh tariff vs 27p grid), AIA at 100% first-year tax relief, 50% First Year Allowance, SHDF Wave 2.2 for housing-association sheltered/extra-care schemes, Smart Export Guarantee for export income. Local-authority commissioning premia are increasingly common — check with your Portsmouth City Council contracts officer whether sustainability scoring affects your bed-rate at next renewal.
For homes co-located with NHS estate (community hospitals, integrated care settings), the Public Sector Decarbonisation Scheme (PSDS) Phase 4 may also apply.

CQC inspection region and regulator presence
Portsmouth sits within the CQC’s South East inspection region. The South East regional inspectorate covers 75+ care homes across the area and applies the 2023 Single Assessment Framework consistently — meaning environmental sustainability under the Well-led key question is being explicitly weighed in inspection reports from this region. Outstanding-rated home reports across the region have increasingly cited installed solar, live generation displays, and family-facing sustainability communication as Well-led evidence.
For Portsmouth operators preparing for an upcoming CQC inspection, the sustainability evidence pack we provide as standard handover documentation is designed to slot directly into the home’s inspection file: system specification with MCS certification, year-on-year generation log, kg CO₂e/year saving calculation, family-facing communication template, and staff briefing pack. Several South East homes have moved from Good to Outstanding on the strength of Well-led improvements that included visible sustainability action.
DNO grid connection in Portsmouth
Grid connection for solar PV in Portsmouth runs through UK Power Networks (UKPN) as the local distribution network operator. For typical care home installs of 30–100 kWp under G99, expect 4–12 weeks from application to acceptance — at the longer end where the local network has constrained capacity, at the shorter end for sites with healthy headroom.
For larger installs above 200 kWp on retirement villages and care villages, expect 6–18 months. We engage the DNO at desk-feasibility stage to model both connection cost and timing — sometimes the answer is to phase the install across two G99 applications to accelerate first-phase commissioning. Portsmouth’s urban core typically has constrained capacity (more development competing for grid headroom); peripheral and suburban locations are usually faster.
Local authority commissioning context
For care homes holding LA-commissioned beds in Portsmouth, sustainability scoring is increasingly part of contract renewal. Portsmouth City Council has set a 2030 net zero target and is increasingly weighting environmental factors in care home commissioning frameworks. The technical evidence pack we provide — system spec, generation data, SECR-aligned CO₂ accounting, and 5-year carbon reduction trajectory — is what Portsmouth contracts officers ask for at retender.
A growing number of UK local authorities pay a sustainability premium on bed rates where operators demonstrate carbon-reduction action. Hampshire, Manchester, Devon, and Surrey have piloted £2–£10/bed/week uplifts on LA-commissioned beds where the home has installed renewables. Check with your Portsmouth contracts officer at next renewal — and bring the technical evidence pack we provide as standard.
Typical install programme timeline for a Portsmouth care home
For a typical 50-bed home in Portsmouth commissioning a 50 kWp solar install:
| Phase | Duration | Notes |
|---|---|---|
| Free desk-based feasibility | 7 working days | Half-hourly meter data analysis + roof photo review |
| Site survey | 2–3 weeks from quote acceptance | Structural and electrical engineer visit |
| Final design and DNO G99 application | 1–2 weeks | Application submitted to DNO |
| DNO G99 approval (parallel-tracked with install prep) | 4–12 weeks | Variable by local network |
| Mobilisation and install | 5–15 working days on site | Scheduled around mealtimes and visiting hours |
| Commissioning and customer training | 3–5 working days | Live generation display setup, staff briefing |
| Total from signed quote to commissioning | 12–20 weeks |
For listed buildings (around 8% of UK care home stock), add 12–16 weeks for Listed Building Consent. For sites with asbestos survey requirements (pre-1980 conversions), add 2–4 weeks for the asbestos process.
Operators we typically work with in Portsmouth
A mix of operators serve Portsmouth’s care home estate. National group operators with multiple sites in or around Portsmouth include Care South, Colten Care, Bupa. Each group typically runs 2–8 sites in the Portsmouth area, often with portfolio-level estate decisions managed centrally. For these operators we structure portfolio-level procurement — volume pricing, standardised technical specification, sequenced DNO applications, and unified SECR Scope 2 reduction reporting at group level.
Regional and independent operators make up the substantial majority of Portsmouth’s estate — typically 60–75% of homes by count. For independent operators, the decision-maker is usually the owner-director directly, and the conversation is more capital-alternative (“the £40k could fund the refurb or the new wing extension”) than IRR-spreadsheet. PPA is the most commonly chosen route for independent Portsmouth operators, with capital purchase + AIA the next-most-common for tax-paying operators with capital available.
