What a Zero-Capex Solar PPA Is (Investor Owns, Estate Buys kWh)
A zero-capex solar PPA is a UK commercial contract where a specialist green infrastructure investor funds, owns, and operates the solar PV system, and the commercial estate buys the electricity it generates under a Power Purchase Agreement at a contracted rate. The landlord’s capital expenditure is £0 for design, kit, and install. The buying decision shifts from installing panels to contracting cheaper kilowatt-hours, which is the friction landlords actually vote on.
- Who owns the asset: a specialist green infrastructure investor, not the estate.
- Who consumes the power: the park and its occupiers.
- How payment works: a per-kWh offtake for electricity used, not a purchase of the array.
This is not a grant, free gift, or zero-cost energy. It is a long-term commercial offtake contract, not a US tax credit or overseas scheme. The estate becomes an offtaker of electricity rather than a purchaser of hardware, which is what makes the model work for landlords who cannot justify a capital vote.
Who This Programme Is For: Landlords and Estate Managers Stuck on Capex
This service is for commercial landlords and estate managers of multi-tenant business parks who want renewable electricity without funding the hardware. The typical barrier is a capital vote — for example, a landlord who could not justify a £1.2m multi-building outlay — alongside mixed lease terms and consent, fair allocation of solar versus service-charge electricity, and the desire for green credentials without buying the plant.
Suitable if
- The barrier is capex and you will buy power under a long-term PPA.
- Multi-tenant park with mixed lease terms needing fair allocation.
- Want green credentials backed by a financial mechanism via master metering.
Not suitable if
- You require full ownership from day one.
- You expect a grant, free gift, or zero-cost energy with no offtake.
- You will not enter a long-term commercial offtake contract.
A mix of lease terms is a normal estate constraint, not a reason to abandon solar; allocation is an operations problem solved later via master metering.
Bristol Business Park Outcomes: 800 kWp With £0 Landlord Capex
Bristol Business Park in Bristol, South West, completed in 2024, is a 12-acre park with 6 buildings and an 800 kWp system. The landlord wanted better green credentials and lower service-charge electricity costs but could not justify the £1.2m capital outlay. Varying tenant lease terms complicated cost allocation and consent. Bee Solar structured a 20-year PPA with a specialist green infrastructure investor who owns the systems and sells electricity to the park at a fixed rate 30% below grid prices. This project’s contracted rate, not a guaranteed saving for every site.
| Outcome | Project Result |
|---|---|
| Landlord capital expenditure | £0 |
| Service-charge electricity costs | Reduced by 30% immediately |
| Tenant satisfaction | Increased with green building credentials |
| Park valuation | Enhanced with renewable infrastructure assets |
| Ownership option | Contractual option to purchase systems at year 10 |
The percentages and £0 capex are Bristol project results, not a universal promise. Every project starts with a free site survey. The year-10 purchase option is a contractual risk-reducer, not a teaser that the landlord will own the system anyway — it is an option, not an automatic transfer.

Master Metering for Multi-Tenant Parks and Mixed Leases
A master metering and billing system allocates solar supply transparently between common areas and participating tenants. It exists because individual tenants’ varying lease terms made cost allocation and consent complex at Bristol. This type of project demonstrates the practical approach to overcoming fragmented roof access and multiple landlord constraints.
Estate managers focus on service-charge electricity versus tenant supply, not household billing language. The ownership split stays consistent: the investor owns the plant; the park and its users consume and pay for solar kWh.
How Allocation Works
- Common areas: solar supply reduces service-charge electricity costs.
- Participating tenants: solar supply is allocated and billed per their lease terms.
Parks fail on allocation, not on panel technology; master metering is the estate answer.
Solar PPA vs Buying the System (CAPEX)
Choose offtake (PPA) versus owning the asset from day one. This comparison resolves the core commercial decision. Understanding the mechanics here is essential; for a broader view, you can also explore how virtual PPAs differ from physical offtake structures.
| Factor | Solar PPA (Offtake) | Buying the System (CAPEX) |
|---|---|---|
| Capex | Investor funds the system | Landlord funds the system |
| Ownership | Investor owns until any contractual purchase option | Landlord owns |
| Payment | Contracted £/kWh for power used | Pay for the asset upfront |
If the barrier is a capital vote, a PPA is the path. If you want full ownership immediately, this programme is not that product.
A PPA is a long-term offtake, not a delayed “free ownership” product; ownership changes only if the year-10 purchase option is exercised, as at Bristol.
Limitations of a Solar PPA (Not a Grant)
A solar PPA is not free energy; its downsides are structural, not hidden fees. Zero capex means no hardware purchase by the landlord; it does not mean zero obligation, because there is a long offtake contract.
Long tenor: 20-year PPA at Bristol.
Investor ownership until any contractual buyout.
Offtake commitment to buy solar kWh.
Roof or land access for an investor-owned plant.
Mixed-lease consent is still required.
The offtake commitment is the trade-off for avoiding the capital outlay. For estates concerned about the long-term operational side, understanding managing system performance over time is a key consideration. Furthermore, any excess generation exported to the grid could potentially be managed under the Smart Export Guarantee, adding another layer to the financial ecosystem.
How the Programme Starts: Free Site Survey
Every project starts with a free site survey. The survey is the decision tool for mixed-lease parks: it determines scope, complexity, and whether a PPA fits before anyone discusses a capital vote. This initial stage mirrors the feasibility audit process used in similar commercial projects to de-risk the investment.

Frequently Asked Questions
What does zero CAPEX mean for a commercial solar PPA?
Zero CAPEX means the landlord spends no capital on the design, equipment, or installation of the solar system. A specialist green infrastructure investor funds and owns the asset, and the estate buys the electricity it generates under the PPA.
Is a zero-capex solar PPA a grant or free electricity?
No. A zero-capex solar PPA is a commercial offtake contract, not a grant, free gift, or zero-cost energy. The estate pays a contracted rate for the solar kWh it consumes.
Who owns the solar system and who consumes the power?
A specialist green infrastructure investor owns the solar system. The commercial estate and its occupiers consume the power and pay for it per kWh under the PPA.
What is the downside of a solar PPA?
The main downsides are the long tenor (20 years at Bristol), investor ownership until any buyout, the offtake commitment to buy solar kWh, and the need for roof or land access for an investor-owned plant.
How does a solar PPA compare with buying the system (CAPEX)?
With a PPA, the investor funds and owns the system and the estate pays a contracted £/kWh. Buying the system means the landlord funds and owns the asset and pays the capex upfront.
How are savings allocated on a multi-tenant business park?
A master metering and billing system allocates solar supply transparently between common areas and participating tenants, reducing service-charge electricity costs and billing tenants per their lease terms.
Are the 30% savings guaranteed for every estate?
No. The 30% reduction in service-charge electricity costs and the fixed rate 30% below grid prices are results from the Bristol Business Park project, not a universal promise.
What happens at year 10 of the PPA?
At Bristol, the landlord has a contractual option to purchase the solar systems at year 10. This is a risk-reducer, not a guarantee of automatic ownership.
Is this the same as a US solar tax credit or overseas “zero capex” scheme?
No. This is a UK commercial offtake contract, not a US tax credit or an overseas scheme. The investor owns the asset and the estate buys the electricity it generates.
How do we start—what is the free site survey?
Every project starts with a free site survey. It assesses the site’s scope, complexity, and whether a PPA fits before any capital vote is discussed.
