We then added VAT at 5%\u0026amp;nbsp;and summed the implied bill components for gas and electricity together to derive an estimate of the overall costs making up a dual fuel bill.\u0026lt;\\\/p\u0026gt;\\r\\n\\r\\n\u0026lt;p\u0026gt;Note that because it is based on the total costs and customer numbers reported by suppliers irrespective of their tariff type, the bill breakdown for gas will reflect a mixture of the costs of serving gas to dual fuel and single fuel customers \\u2013 and the same also applies to electricity. As such, the dual fuel breakdown should be considered an approximation\u0026amp;nbsp;in that it will reflect a combination of the costs incurred in serving gas and electricity to both dual fuel and single fuel customers (which may differ if, for example, electricity-only customers consume more electricity than those customers that are also supplied with gas).\u0026lt;\\\/p\u0026gt;\\r\\n\\r\\n\u0026lt;p\u0026gt;The data presented is based on the latest available \u0026lt;a href=\\\u0026quot;\\\/gas\\\/retail-market\\\/monitoring-data-and-statistics\\\/understanding-profits-big-energy-suppliers\\\u0026quot;\u0026gt;Consolidated Segmental Statements\u0026lt;\\\/a\u0026gt;.

Supplies from these two sources accounted for 48% and 36% of the total gas supply respectively, up from shares of 29% and 32% in the previous quarter. Liquefied natural gas (LNG) decreased its share of total supply sharply from Q1 2026 (30%) to Q2 2026 (6%), with supplied volume falling from 7.1bcm to 0.8bcm, likely reflecting the impact of tighter global LNG supplies associated with the war in the Middle East.

Demand for interconnector exports from Great Britain to other regions increased in Q2 2026, from 2.4bcm in Q1 2026 to 4.0bcm in Q2 2026, but were down from the same period last year (4.3bcm in Q2 2025).

The decrease in quarter-to-quarter volatility was driven by the start of the Middle East conflict occurring in Q1 2026 causing a significant increase in prices with strong price variation between days. In Q2 2026, prices settled at a lower level and with less variability as the conflict entered a more stable state. However, volatility was still higher in Q2 2026 than in the same period last year when there was less risk sentiment in the market.\u0026amp;nbsp;\u0026lt;\\\/p\u0026gt;\u0026lt;p\u0026gt;Volatility in day-ahead baseload power prices increased by 30 percentage points quarter-on-quarter and by 18 percentage points year-on-year. Peakload power price volatility rose by 236 percentage points quarter-on-quarter and by 5 percentage points year-on-year. The volatility in the day-ahead power market was driven mostly by changes in renewable generation day-to-day, with wind generation in particular varying from very low wind days (where prices are typically higher) to very high wind days (where prices can drop to very low levels). The strong swings that can occur between days drives greater volatility in the day-ahead power market, particularly peakload, than is typically observed in the gas market for the day-ahead contract.\u0026amp;nbsp;\u0026lt;\\\/p\u0026gt;\u0026lt;h3\u0026gt;Relevance and further information\u0026lt;\\\/h3\u0026gt;\u0026lt;p\u0026gt;Price volatility is an important market indicator for a range of reasons.

However, gas prices steadily increased throughout the rest of August as hostilities reignited and peace talks stalled. Asian demand increased at the end of August as the end of the summer refilling season approaches and countries look to bolster their reserves in a tight market ahead of the winter season. Whilst European storage fullness increased from 57% to 65% across August, it is still below historic levels (77% on 31 August 2025) and remains an important factor as LNG demand is likely to increase if the upcoming winter season is especially cold. Maintenance outages to Norwegian pipeline supply were also a factor in the second half of August and contributed to gas prices for contracts delivering in the next six months reaching their highest level since the conflict in the Middle East began. This was despite lower gas demand and higher wind generation which decreased day-ahead power prices. Longer term power prices tended to track gas price increases, although they were less pronounced as renewables and European supply from other sources (e.g. nuclear) are important independent determinants.\u0026lt;\\\/p\u0026gt;\u0026lt;p\u0026gt;For more detailed updates on wholesale prices visit \u0026lt;a href=\\\u0026quot;https:\\\/\\\/www.ofgem.gov.uk\\\/energy-data-and-research\\\/data-portal\\\/wholesale-market-indicators\\\u0026quot;\u0026gt;Wholesale market indicators | Ofgem\u0026lt;\\\/a\u0026gt;.\u0026lt;\\\/p\u0026gt;\u0026lt;p\u0026gt;In August 2026, the average number of fixed tariffs on offer increased compared with July 2026.

It\\u2019s an energy supplier\\u2019s basic offer. If a customer does not chose a specific energy plan, for example after their fixed tariff ends, they will be moved on a standard variable tariff until they have chosen a new one.

As noted, there was a large dip in Q4 of 2024. This appears to be like the pattern observed between 2023-24 where a dip post Q3 was observed but a recovery was made in around Jan 2024. There was a slowdown in Q225. There was a second increase in activity during Q325 which briefly continued into Q425. However, a slight slowdown was observed as the year closed\u0026lt;\\\/p\u0026gt;\u0026lt;p\u0026gt;In Q126 switching was observed to have increased in both fuels, with the highest point being reached in March 2026.\u0026amp;nbsp;\u0026lt;\\\/p\u0026gt;\u0026lt;p\u0026gt;In July 2026, total number of switches decreased slightly by an average of 0.7% across both fuels compared with June 2026.\u0026amp;nbsp;\u0026lt;\\\/p\u0026gt;\u0026lt;p\u0026gt;The proportion of customers switching to other suppliers (dual fuel) remained high at 54% in July 2026. While net switching to other suppliers decreased by 9% for electricity and 12% for gas compared with June 2026, net gains remained strong overall. This suggests that customers continued to switch towards other large, medium and small suppliers, despite a modest month-on-month decline in net gains.\u0026lt;\\\/p\u0026gt;\u0026lt;h3\u0026gt;Relevance and further information\u0026lt;\\\/h3\u0026gt;\u0026lt;p\u0026gt;External switching, from one supplier to another, is one measure of consumer engagement with the market.
