How the PPA Structure Operates
Delivery is structured through a long-term Power Purchase Agreement (PPA).
​
In simple terms:
​
-
A third-party fund finances, installs, owns, and maintains the solar system.
-
The building purchases the electricity generated on site at an agreed PPA rate.
-
This displaces higher-cost grid electricity with lower-cost on-site generation.
-
No capital contribution is required from the landlord.
-
No operational or maintenance burden sits with the asset owner.
-
​
Agreements are typically structured around 25 years, with buy-out options available from year 7 onward.
​
Security of tenure and counterparty strength are assessed on a building-by-building basis.
​
From an asset owner perspective, the structure reduces energy cost volatility without deploying capital.
Design Approach
Building-Specific, Not Template-Led
​
There is no standard design.
​
Each building is assessed individually for structural, electrical, and commercial suitability.
Solutions may include:
​
-
Roof-mounted solar PV
-
Installations within roof apex
-
Over-roof, canopy, or mezzanine structures
-
Ground-mounted arrays (where land permits)
​
Where appropriate, the funded structure can also incorporate:
​
-
Roof repairs (within agreed funding thresholds)
-
Battery storage
-
EV charging infrastructure
-
Electrical upgrades
-
Heating systems (subject to commercial viability)
​
Wider scope affects capital deployment and therefore final PPA pricing.
LANDLORD STRATEGIC BENEFIT
Who We Are
Under long FRI leases, direct electricity savings typically benefit tenants.
​
However, when structured correctly, landlord value can be strategic and financial.
​
Potential landlord benefits include:
​
-
Enhanced ESG profile and EPC positioning
-
Improved refinancing and valuation positioning
-
Reduced MEES and carbon compliance exposure
-
Stronger tenant retention and satisfaction
-
No capital deployment
​
In addition, a landlord revenue share structure can be incorporated.
​
This enables:
​
-
Recurring income linked to on-site generation
-
No billing or operational burden
-
No energy supply regulatory exposure
-
No interference with tenant supplier choice
DUAL SUPPLY STRUCTURE
Operating Alongside Existing Electricity Supply
The PPA does not replace the tenant’s energy supplier.
Instead:
-
Tenants retain their existing grid supplier
-
The PPA sits “behind the meter”
-
Solar generation displaces a portion of imported power
This structure avoids interference with tenant supplier choice and regulatory exposure.
​SCOPE OF FUNDED WORKS
Broader Than Solar
The funding structure can incorporate:
​
-
Solar PV systems
-
Battery storage
-
EV charging infrastructure
-
Roof repairs (up to agreed percentage of total project value)
​
Where roof condition is a concern, funded integration of roof works can significantly reduce landlord capex exposure.

LEASE LENGTH & SUITABILITY
Selective, Asset-Led Deployment
PPA terms typically range between 10–30 years.
Suitability assessment focuses on:
​
-
Longer unexpired lease terms
-
Strong covenant strength
-
Stable occupancy profiles
​
There is no obligation to include all units.
Assets are assessed selectively.
ROOF LIABILITY & STRUCTURAL PROTECTION
Risk Managed Through Structured Protections
Installations proceed only following structural validation and condition assessment.
​
Protections include:
​
-
Installer liability for penetrations and detailing
-
Collateral warranties in favour of landlord
-
Performance guarantees
-
Defect liability provisions
-
Removal and reinstatement clauses within PPA documentation
​
Where roofs are 20+ years old, installation proceeds only if structurally appropriate or aligned with planned refurbishment.
