Leased Solar Panels for UK Businesses — 2026 Lease Models Explained
How leased solar panels work for UK businesses in 2026. Operating lease, capital lease, hire purchase, and lease-to-own — with tax treatment.
How leased solar panels work in the UK
“Leased solar panels” covers four distinct lease structures in the UK 2026 commercial market. The right one depends on your accounting treatment, balance-sheet preferences, and ownership intent at term-end.
- Operating lease — lessor (financier) owns the system; you pay monthly rent; system is OFF balance sheet (IFRS 16 has tightened this); rent is fully tax-deductible operating expense; system reverts to lessor at term end.
- Capital lease / finance lease — you take economic ownership for accounting purposes; system is ON your balance sheet; you depreciate it; you can claim capital allowances.
- Hire purchase — you take legal ownership progressively; final lump sum transfers full title; treated as your asset for tax purposes from day 1; AIA applies.
- Lease-to-own — effectively hire purchase with a defined buyout option at year 5, 7 or 10. Most popular UK structure for commercial solar in 2026.
Lease vs PPA — key distinction
A lease is a contract to use a defined asset for monthly payment. A PPA (Power Purchase Agreement) is a contract to buy a defined commodity (electricity in kWh) at an agreed price.
Under a lease, your monthly payment is fixed regardless of how much electricity the system generates. Under a PPA, your payment varies with kWh consumed. PPAs put generation risk on the third party; leases put it on you.
For UK factories, PPAs are typically cheaper if your roof is genuinely suitable (well-modelled yield); leases are cheaper if you want predictable budgeting and accept some yield risk.
Lease pricing in 2026
Typical 2026 lease pricing for a UK 250 kW factory solar install (capex equivalent £180,000):

Year-1 electricity savings from the same system: ~£58,000/year (~£4,800/month). Every lease structure listed above is cash-flow positive from month 1.
