What to expect, checked 3 November 2026: a Nottinghamshire canopy will almost certainly be funded without a grant. PSDS is closed and no national canopy grant is open in England, so a business case rests on capital allowances and own funds, finance or a PPA, compared under if a grant doesn’t fit.
Nottinghamshire’s commercial sector is navigating a significant inflection point. Nottingham City Council has committed to a 2028 net zero target — one of the most ambitious carbon neutrality timescales of any major UK city — and businesses across the city and wider county are increasingly under pressure to demonstrate credible decarbonisation progress. At the same time, commercial electricity prices across the East Midlands remain stubbornly high at 28–32p/kWh, making on-site generation a financial imperative as well as an environmental one.
Commercial solar canopies — permanent canopy structures over car parks or service yards carrying solar panels — sit at the intersection of these pressures. They generate clean electricity at the point of use, reduce grid exposure, provide covered parking, and create a visible sustainability signal. For public sector bodies the funding position has changed: the Public Sector Decarbonisation Scheme (PSDS) closed to new applications in November 2024. For private businesses, the Annual Investment Allowance still delivers year-one tax relief on the first £1 million of qualifying spend.
This guide explains both pathways in detail, along with real costs, NGED connection requirements, and planning considerations for Nottinghamshire sites.
The PSDS Position for Nottinghamshire Public Bodies
The Public Sector Decarbonisation Scheme was administered by Salix Finance on behalf of the Department for Energy Security and Net Zero (DESNZ). It closed to new applications in November 2024. Phase 4 allocations are still being paid out to bodies that bid before that window shut — the phase covers financial years 2025-26 to 2027-28 — but there is no open window and no further phase has been announced. The gov.uk PSDS collection page lists Phases 1 to 4 only and was last updated on 13 March 2025.
Two things are worth correcting in any older Nottinghamshire business case. PSDS was heat-led: solar was fundable as part of a bid whose primary measure was replacing fossil-fuel heating in the same building, so “100% grant for a car park canopy” overstated it even while a window was open. And Salix does not run a general interest-free loan scheme for English public bodies — administering PSDS is a different thing from a loan facility.
Who Was Eligible in Nottinghamshire?
While a window was open, eligible organisations included:
- Nottingham City Council and its arms-length bodies
- Nottinghamshire County Council and the county’s district and borough councils
- NHS Nottinghamshire Integrated Care Board and all NHS trusts, including Nottingham University Hospitals NHS Trust and Nottinghamshire Healthcare NHS Foundation Trust
- University of Nottingham and Nottingham Trent University
- Further education colleges (Nottingham College, etc.)
- Police and crime commissioners, fire services
- Registered social landlords, through the separate social housing decarbonisation funding route
Where a canopy was funded, it was as generation associated with a public sector building whose heating was being decarbonised in the same bid, with the output credited to that building’s energy account. A canopy over a staff car park was not fundable on its own.
What This Means for a Project Now
A Nottinghamshire public body planning a canopy in 2026 is funding it without a capital grant. The routes that remain open are:
- Capital allowances, for bodies with a taxable trading arm — the Annual Investment Allowance covers the first £1 million of qualifying spend in the period, with a 50% first-year allowance on the balance. Solar PV is special-rate plant and does not qualify for full expensing.
- The business rates exemption — on-site renewable generation plant is excepted from rating valuations until 31 March 2035 (England: S.I. 2022/405), so the canopy does not raise the site’s rateable value.
- OZEV Workplace Charging Scheme — £500 per socket, up to 40 sockets per applicant, to 31 March 2027, where the canopy carries EV charging. The education strand is worth £2,000 per socket.
- A PPA or lease, which puts the capital on a third party in exchange for a long supply contract.
- The Smart Export Guarantee for exported units, which requires MCS certification.
Bodies that already hold a Phase 4 allocation still have to deliver inside their agreed timetable, and end-to-end programmes of this type commonly run 12 to 18 months once grid connection is included.
Private Business Route: 100% AIA and Commercial Finance
For private businesses in Nottinghamshire, the PSDS is not available — but the financial case for solar canopies remains strong.
Annual Investment Allowance (AIA)
The 100% Annual Investment Allowance permits businesses to deduct the entire cost of qualifying plant and machinery (which includes solar generation equipment and the supporting canopy structure) from taxable profits in the year of purchase.
For a Nottinghamshire manufacturing business with a £400,000 solar canopy:
| Item | Value |
|---|---|
| Capital investment | £400,000 |
| AIA deduction (100%) | £400,000 |
| Corporation tax relief @ 25% | £100,000 |
| Effective net investment | £300,000 |
| Annual electricity saving (est. 350 kW system) | £95,000 |
| Adjusted payback (post-AIA) | ~3.2 years |
This assumes the business has sufficient taxable profits to absorb the full deduction in year one. Businesses with lower profits can carry forward unused AIA relief.
Commercial Finance Options
Businesses that prefer to preserve capital can use:
- Asset finance / hire purchase: The canopy and solar system are financed over 5–10 years; monthly payments are typically less than the monthly electricity saving from day one, meaning immediate positive cash flow
- Green loans: Several UK banks (NatWest, Lloyds, Barclays) offer preferential rates for renewable energy capital projects — typically 0.5–1.0% below standard business loan rates
- Power Purchase Agreements (PPA): A third-party investor funds and owns the system; the business buys solar electricity at a fixed rate below grid tariffs. No capital required, but long-term savings are lower than ownership
National Grid Electricity Distribution: Nottinghamshire Connections
Nottinghamshire is served by National Grid Electricity Distribution (NGED) — the same DNO as the South West and East Midlands generally. The Nottinghamshire network is well-developed given the East Midlands’ industrial heritage, and most commercial sites around Nottingham, Newark, Mansfield, and Worksop have reasonable export capacity at substation level.
G99 Timescales for Nottinghamshire Sites
| System Size | Route | Typical NGED Timeline |
|---|---|---|
| 3.68 kW – 50 kW | G99 prior approval | 8–12 weeks |
| 50 kW – 1 MW | G99 full application | 14–20 weeks |
| Over 1 MW | DG Agreement required | 9–18 months |
NGED’s network capacity data (published via its interactive map) indicates that many areas around Nottingham city, the A52 corridor, and the M1 junction 26 area have good export headroom. Sites in rural Nottinghamshire (Sherwood, Vale of Belvoir) should check more carefully, as rural substations often have lower spare export capacity.
A pre-application enquiry (PAE) from NGED confirms available capacity formally and takes 4–6 weeks. Cost: £350–£650.
Nottinghamshire’s Commercial Landscape
Nottingham City
Nottingham’s Castlegate Business District, Lace Market, and the Beeston Business Park area host a mix of professional services, technology, and public sector bodies. Car park ownership is often more complex in urban areas, but businesses occupying owned sites or long-leasehold premises have strong canopy potential.
The Nottingham Enterprise Zone (centred on the rail corridor south of the city) and the Boots Campus at Beeston (now Medipark) represent large employers with significant parking assets.
East Leake and the Vale of Nottingham
The A60 and A453 corridors south of Nottingham host a growing number of light industrial and technology businesses. East Leake Business Park and Loughborough Road industrial properties are increasingly occupied by advanced manufacturing and cleantech businesses well aligned with solar investment.
Mansfield, Worksop, and the Ashfield District
The former coalfield areas of north Nottinghamshire — now home to logistics, distribution, and light manufacturing — have some of the best canopy potential in the county. Large, flat surface car parks in industrial zones around Mansfield, Kirby-in-Ashfield, and Worksop offer unobstructed southern exposure.
Cost Benchmarks for Nottinghamshire
| System Capacity | Installed Cost | Annual Generation | Annual Value |
|---|---|---|---|
| 50 kW | £90,000–£120,000 | 45,000 kWh | £12,500–£15,000 |
| 100 kW | £170,000–£220,000 | 90,000 kWh | £25,000–£30,000 |
| 250 kW | £380,000–£490,000 | 225,000 kWh | £62,500–£75,000 |
| 500 kW | £700,000–£950,000 | 450,000 kWh | £125,000–£150,000 |
Based on 1,000 kWh/m²/yr irradiance (East Midlands average), 80% self-consumption at 30p/kWh, 20% SEG at 5p/kWh.

Planning in Nottinghamshire
Nottingham City Council
Nottingham City Council’s Local Plan Part 2 (adopted 2020) is explicitly supportive of renewable energy. In England, a canopy over off-street non-domestic parking can use permitted development Class OA, which always needs prior approval and caps the height at 4 metres above ground (see the planning permission guide).
Nottinghamshire County and Districts
Outside Nottingham City, the county’s seven district and borough councils (Ashfield, Bassetlaw, Broxtowe, Gedling, Mansfield, Newark & Sherwood and Rushcliffe) each have their own local plan. All broadly follow NPPF principles that support renewable energy. Rushcliffe Borough Council (which covers East Leake and Radcliffe on Trent) has adopted a proactive sustainability agenda.
Article 4 Directions removing permitted development rights are uncommon on employment/industrial land in Nottinghamshire, but always worth confirming with the local LPA.
Key Questions Answered
Can we still apply to PSDS? No. The scheme closed to new applications in November 2024 and no further window has been announced. Bodies that secured a Phase 4 allocation before it closed are delivering against it through to 2027-28. If you are working from a business case written before 2025, the grant line needs replacing.
What should a private business use instead? PSDS was only ever open to public sector bodies. A private business funds a canopy through capital allowances (AIA on the first £1 million, then a 50% first-year allowance on the balance), asset finance, or a PPA, and benefits from the rates exemption on the generation plant in the same way a public body does.
Does Nottingham City Council’s 2028 net zero target affect planning applications? Yes, positively. Planning officers in Nottingham City have a policy mandate to support decarbonisation investment. Well-prepared solar canopy applications are processed favourably.
How does Nottinghamshire’s irradiance compare to southern England? East Midlands irradiance averages ~1,000 kWh/m²/yr, approximately 15% less than Cornwall and 5–7% less than Bristol. This reduces annual generation but doesn’t fundamentally change the investment case, particularly when AIA is applied.
Can we split a large project to stay under NGED thresholds? Technically possible but not advisable. DNOs assess the total connected generation capacity of a site, not individual connection applications. Attempting to split a 200 kW system into four 50 kW applications would be rejected as load splitting.
Where That Leaves a Nottinghamshire Project
The grant that most public-sector canopy cases in the county were built on is gone, and nothing has replaced it. What has not changed is the underlying arithmetic: a canopy over a car park you already own generates into a site load you already pay for, the generation plant stays out of the rateable value until 2035, and the structure has a 25-year design life. Cases that stalled in 2025 waiting for a window are worth re-running on ownership versus PPA instead.
