OWNERSHIP-BASED ALLOCATION
Solar Carbon Allocation for Landlords and Tenants
NZC Solar records generation, consumption and export data so commercial property owners can allocate financial value, billing charges and carbon reporting evidence across landlords, tenants and occupiers.
Why carbon allocation matters
On a commercial property, the party that owns a PV system is not always the party that consumes its electricity — and neither may be the party with the strongest claim to the carbon benefit. Without clear allocation, financial value and carbon evidence can be double-counted, under-claimed or unsupported on audit.
- Landlords may own the PV system.
- Tenants may consume the electricity generated on site.
- Exported electricity may create export revenue separate from on-site use.
- Service charge or PPA agreements may determine how financial value is allocated.
- Carbon reporting treatment depends on ownership, consumption, contract terms and reporting boundary.
- Poor allocation creates double-counting risk between landlord and tenant disclosures.
Agreement models supported
NZC Solar and the NZC Portal handle the ownership and metering structures we see most often across UK commercial property.
Landlord-owned PV with tenant PPA
Landlord retains the asset; tenant purchases on-site generation at a contracted PPA rate.
Landlord-owned PV via service charge
Generation cost or benefit is recovered through the service charge mechanism set out in the lease.
Tenant-owned PV
Tenant funds and owns the system, retaining both financial value and carbon claim against their occupational footprint.
Third-party-owned PV
An external investor owns the system and contracts supply or export with landlord and tenant separately.
Export-only landlord revenue
Landlord receives export tariff income; on-site consumption is minimal or routed elsewhere.
Common parts consumption
PV offsets landlord-controlled electricity supplying lifts, lighting, plant and shared areas.
Mixed-use estate allocation
Multi-tenant estates with retail, office and residential demand allocated across distinct meters and contracts.
What NZC Solar tracks
Every site is set up with ownership, metering and allocation parameters so the platform can produce attributable financial and carbon outputs.
Carbon and export evidence
NZC Solar records the evidence required to support disclosure using deliberately careful wording. The platform produces carbon benefit, avoided emissions evidence, renewable generation evidence, Scope 2 reduction evidence and export carbon evidence — not unqualified offset claims.
Exported PV generation is recorded against the PV system owner unless contractual rights assign the benefit elsewhere. NZC Solar records the evidence required to support disclosure, while formal reporting treatment should be reviewed against the applicable methodology.
Avoiding double counting
The same kWh should not be claimed simultaneously by landlord and tenant. NZC Solar makes the attribution explicit so financial value and carbon evidence stay aligned with the underlying contract and reporting boundary.
Landlord-owned PV, tenant PPA
- Landlord receives PPA revenue.
- Tenant receives electricity supply benefit.
- Carbon reporting treatment depends on contract and reporting boundary.
Landlord-owned PV, exported electricity
- Landlord receives export income.
- Exported kWh recorded as landlord-owned renewable generation evidence.
- Claim must be supported by metered export data.
Common parts consumption
- PV offsets landlord-controlled electricity.
- Carbon benefit normally sits with landlord-controlled operational emissions.

Carbon allocation depends on ownership, metering, contractual rights, reporting boundary and applicable reporting methodology. NZC Solar records generation, consumption and export evidence but does not treat exported electricity as an automatic carbon offset without review.
