Solar asset finance in Portsmouth
Whole-of-market commercial solar finance for businesses across Portsmouth and the wider Hampshire area, including Gosport, Fareham, Havant.
Portsmouth runs on a densely concentrated commercial base — a defence and naval supply chain, a working international port, and tightly packed trading estates where electricity is one of the largest controllable overheads. For a finance director here, the question is rarely whether commercial solar pays back. With an average commercial energy spend around £38,000 a year across local businesses, the payback maths is usually compelling. The real question is how to fund the capital outlay without draining working capital that the rest of the business needs. That is where asset finance comes in, and it is the only thing we arrange.
We are a commercial solar asset finance brokerage. We do not install panels and we are not a generic solar site. We structure the funding — hire purchase, finance lease, operating lease, equipment loans and sale-and-leaseback — so a Portsmouth business can put solar on the roof now and pay for it out of the savings it generates. Your chosen MCS installer does the engineering; we make the numbers work.
Why Portsmouth businesses finance solar rather than buy it outright
A 100kW–250kW commercial array on a Lakeside North Harbour office block or a Walton Road industrial unit is a six-figure capital decision. Paying for it from cash means tying up money that could fund stock, recruitment, vehicles or a tender. Most local firms would rather keep that cash liquid and let the solar pay for itself month by month.
The economics are particularly stark in Portsmouth because of who operates here. The naval and defence supply chain that the council itself flags as a major commercial energy concentration runs energy-hungry workshops, fabrication and testing facilities with high daytime baseload — exactly the demand profile solar serves best. The same is true of the logistics and distribution tenants clustered around the Airport Industrial Estate and Voyager Park, where large flat roofs sit over operations that draw power through the working day.
Asset finance lets these businesses act on that opportunity without a capital business case competing against every other use of cash. The system is funded against the savings it produces, and ownership-based routes keep the tax reliefs and export income with the business rather than handing them to a third party. You can model your own figures on our finance calculator and check typical system pricing on our cost page before you talk to anyone.
Which finance routes suit Portsmouth firms
Different balance sheets and different intentions call for different structures. The main routes we arrange:
Hire purchase
The most common choice for owner-managed Portsmouth businesses that want the asset on their own balance sheet. You pay a deposit and fixed monthly instalments, and at the end of the term you own the system outright. Critically, with solar hire purchase the business owns the equipment from day one for tax purposes — so you claim the capital allowances and you keep every penny of Smart Export Guarantee income.
Equipment loan
A solar equipment loan works similarly on the ownership question — the business owns the asset and claims the allowances — but the funding sits as a straightforward loan secured against the equipment rather than a hire-purchase agreement. Useful where you want to keep installer and funder separate, or fold solar into a wider capital expenditure facility.
Finance lease
With a solar finance lease the lessor retains legal ownership and usually claims the capital allowances themselves, passing the benefit back through lower rentals. Rentals are fully deductible against profit. This suits businesses that want the lowest possible monthly cost and are comfortable not holding the allowances directly.
Operating lease
A solar operating lease keeps the asset off your balance sheet entirely. You do not claim allowances, but the rentals are an operating cost deductible against profit. It appeals to firms that prioritise clean balance-sheet treatment and predictable monthly outgoings over ownership.
Capital purchase and refinance
If cash is genuinely abundant, solar capital purchase buys the system outright and you own and claim everything from the start. And if you have already installed solar from reserves, sale-and-leaseback releases that capital back into the business while spreading the cost over a rental term.
A worked example on a named local estate
Take a logistics operator on Voyager Park running a 120kW rooftop array. Indicative system cost is around £108,000. Funded on a five-year hire purchase, monthly repayments come to roughly £1,950. Against a modelled energy saving comfortably above that figure for a high-daytime-use site, the system is broadly self-funding from month one — and because hire purchase is an ownership route, this operator claims the capital allowances and banks the Smart Export Guarantee income on every exported unit. (Illustrative figures only; your installer’s design and a current quote drive the real numbers.)
Capital allowances, ownership and why PPAs cost you the upside
This is the part most generic solar sites get wrong, and it is where the route you choose has real money attached.
Solar PV is special-rate expenditure for capital allowances. It does not qualify for 100% full expensing — that relief is reserved for main-rate plant. What it does qualify for is the Annual Investment Allowance (AIA) at 100% on up to £1m of qualifying spend per year, with the 50% first-year allowance applying to expenditure above that threshold. Both the AIA and the 50% FYA are permanent reliefs, so a typical Portsmouth commercial array sits comfortably inside 100% relief in the year of installation.
But you only get those allowances if you own the asset. The ownership question is decided entirely by how you fund it:
- Hire purchase, equipment loan or cash purchase — the business owns the system and claims the capital allowances itself.
- Finance lease — the lessor usually claims the allowances and passes the benefit through in lower rentals.
- Operating lease — no allowances for you as lessee, but the rentals are deductible.
- Power Purchase Agreement (PPA) — the third-party funder owns the array, claims the allowances, and keeps the Smart Export Guarantee income for itself. You simply buy the power.
That last point is the crux. A PPA can look attractive because there is no capital outlay, but the funder captures the tax relief and the export revenue — the very upside that makes solar a strong investment. Owning the system through asset finance keeps the AIA and the SEG income with your business. Our full breakdown is on the capital allowances page, and we set the two approaches side by side on asset finance vs PPA so you can see exactly what each route leaves on the table.
The local net-zero and council policy driver
Portsmouth has committed to net zero by 2030 under its Portsmouth Climate Emergency Plan — one of the more ambitious city-level targets in the South East. For local businesses, that political backdrop increasingly shapes procurement, planning and tenant expectations: landlords on estates like Quartremaine Road and Walton Road are fielding more questions about on-site generation, and public-sector and defence buyers increasingly weight supplier carbon credentials.
There is also a tangible financial dimension. Solent Freeport status is applicable to qualifying sites in and around Portsmouth, which can unlock Enhanced Capital Allowances within designated zones — worth checking against your specific location before you finalise a funding structure, as it can change the optimal route. Combined with the council’s net-zero plan and the energy concentration in the naval and defence supply chain, the direction of travel is clear: businesses that own their generation are better placed than those locked into a third-party PPA. We outline the wider incentive landscape, including grants and the Smart Export Guarantee, on our grants and funding page.
Neighbouring Gosport, Fareham, Havant, Waterlooville and Southsea share the same Solent grid and the same commercial pressures, so the funding logic that works for a Portsmouth business applies right across the conurbation.
