Energy monitoring software: the kWh every UK report starts from

Software that collects energy data — interval meter readings, utility bills and sub-meter readings — and shows consumption by site, by use and over time, in kWh.

It is the data layer that energy management, ESOS audits, SECR reporting and carbon accounting all start from.

Monitoring collects and shows the data.

Management adds the system around it: targets, indicators, baselines, actions and owners, as ISO 50001 describes.

Many products do both; the difference matters when you write the specification.

The market is moving there.

Under market-wide half-hourly settlement every GB electricity meter point is being migrated to half-hourly settlement: migration started on 22 October 2025, suppliers must be qualified by 28 October 2026 and migration is due to complete on 7 May 2027.

Settlement moving to half-hourly does not by itself give the customer a data feed; that depends on the meter and the supplier.

It moves electricity settlement from profiled estimates to actual half-hourly consumption, and shortens the settlement timetable from 14 months to four months at the cutover planned for 2 July 2027.

For a business it means bills and settlement rest more on measured use.

It overlaps.

Bill management checks invoices, flags estimates and errors, and keeps the cost and kWh record; monitoring adds meter data.

For reporting, the important test is that estimated bills are labelled and replaced with actual reads.

SECR asks for energy used in kWh in the directors’ report; ESOS calculates total energy consumption in kWh or in pounds, and since 22 July 2026 states savings in kWh; ISO 50001 tracks energy performance with indicators and baselines.

All three start from the same meter and bill data.

It can show it: NESO publishes Great Britain’s grid intensity by half hour.

But that is an operational number for timing use.

Reported emissions for SECR use the DESNZ conversion factor for the year in which the energy was used.

No rule requires them.

An ESOS audit must, where appropriate and reasonably practicable, rest on energy consumption profiles — a breakdown of how energy is used — so sub-metering often makes the audit cheaper and better.

Not by Ofgem directly.

Ofgem calls them third party intermediaries; the rules bite on suppliers, who must show broker costs paid through the bill and may only work with brokers that belong to a qualifying dispute settlement scheme.

Check who is giving you the data and how it is paid for.

Often not.

An unquoted company is in SECR only if it is large, and one using 40,000 kWh or less may say so instead of disclosing its figures.

Monthly bills in a spreadsheet are enough for many small firms.

In ESOS, a breakdown of the different ways energy is used by the activities and assets of the organisation and, where appropriate, an analysis of how that use varies.

It is what an audit is built on, and monitoring data is how you get one.

No. This page is built from the ESOS and SECR legislation, DESNZ, NESO, Ofgem and the MHHS programme, each cited. It names no products and ranks none.
