What DESNZ published
The Department for Energy Security and Net Zero (DESNZ) published Quarterly Energy Prices: September 2026 on 29 September 2026. GOV.UK labels the release as accredited official statistics. The publication covers prices paid by domestic and industrial consumers for major fuels and includes selected international comparisons.
A separate DESNZ data page, Gas and electricity prices in the non-domestic sector, was updated on the same date. It describes quarterly and annual gas and electricity price tables for non-domestic consumers. The tables distinguish prices that include or exclude the Climate Change Levy (CCL) and divide results into consumption-size bands.
Publication month is not the measurement period
“September 2026” identifies the edition and publication month. It does not mean that every figure in the tables measures September 2026. Before using a number, check the original table for:
- the quarter or year covered;
- whether it relates to gas or electricity;
- the unit of measurement;
- whether CCL is included or excluded;
- the applicable consumption band; and
- whether the figure is provisional or has subsequently been revised.
Keeping these labels with the figure is important. Two values can look comparable while using a different period, tax basis or consumption band.
Official statistics are not an individual business quote
The tables provide market context and a consistent statistical reference. They are not an offer from a supplier to a particular business. A contract price may also depend on the customer’s consumption profile, contract duration, payment arrangements, supply-point details, taxes and other charges.
For that reason, an official average should not be compared directly with a bill rate unless the period, unit, tax treatment and other components are aligned. The statistics also do not establish how much a particular business could save.
A practical checking approach
When using these sources, record the table number, period, unit, CCL basis and consumption band. Use the same basis when comparing the information with a quote or contract. If charges, taxes or periods are unclear, ask the supplier or broker to explain them in writing.
EnergyScope provides a way to read and organise public information. It does not provide a live quote, price forecast or “cheapest” claim.
