Smart Metering, Sub‑metering and Energy Data in Multi‑Occupancy Buildings

Smart metering infrastructure provides near‑real‑time consumption data and facilitates more accurate billing and energy management. In multi‑occupancy properties, a layered approach is common: a main supply meter for the building and submeters for individual tenancies or communal systems. Submeters support tenant billing, landlord energy management and the performance measurement of efficiency investments.

Regulatory and data‑privacy frameworks influence how meter data can be accessed, shared and used. Consent and data protection requirements mean that landlords and managers must implement clear policies for collection and disclosure. Operationally, integration with building management systems (BMS) and energy management platforms enables fault detection, load profiling and optimisation of heating, ventilation and lighting systems.

From a practical perspective, meter selection (smart, half‑hourly, or submeters) should align with the intended use of the data. For investment and asset‑management purposes, data quality, storage, and consistent naming conventions are important for long‑term benchmarking. Careful planning at specification stage — including considerations of access for meter readings, supplier switching and metering maintenance — reduces later operational friction and supports compliance with energy performance reporting.
