Understanding landlord, tenant and common-parts solar allocation

May 2026·4 min read

A short reference guide to the three allocation buckets every multi-let solar building has to deal with, and the data you need to support each one.

The three buckets

  • Landlord-retained: areas the landlord operates directly (plant rooms, EV charging behind a landlord meter).
  • Tenant demise: areas served by tenant sub-meters under a PPA or recharge model.
  • Common parts: shared services billed through service charge.

Data needed for each

Each bucket needs its own metering point or a defined apportionment rule, and a documented allocation method that the auditor can follow back to the meter. The platform's Carbon Allocation module records the rules per site and applies them every billing cycle.
