Cornwall Insight has unveiled its latest forecasts for the Default Tariff Cap (price cap) covering the period October 2023 (Q423) to September 2024 (Q324). The predictions, calculated from Ofgem’s updated Typical Domestic Consumption Values1 (TDCV), indicate relatively small fluctuations throughout the year compared to the same period last year. The cap is expected to remain significantly above pre-pandemic levels for the foreseeable future.
As of October 2023, the price cap for a typical dual fuel, direct debit consumer is forecast to reduce to quarter-on-quarter to £1,860. Following this initial dip, the cap is projected to rise to around £1,960 in January, before experiencing small decreases in March and July2.

Dr Craig Lowrey, Principal Consultant at Cornwall Insight said:
“The news of a relative stabilising of energy bills will no doubt leave households with mixed feelings. After the surge in bills seen last winter, it may bring a sense of relief to people that energy prices are currently not forecast to surge unexpectedly. However, there will also be disappointment with prices still well above the levels seen a few years ago – leaving many longing for more affordable options.
“The wholesale market remains the main driver of bills, and unfortunately there is no immediate prospect of prices there returning to historic averages. Therefore, it becomes imperative the government and other stakeholders explore alternative measures to cater to consumers. This includes options to provide targeted support to the most vulnerable while promoting flexible energy solutions that encourage efficient energy usage.
“Moreover, we must remain committed to funding the transition to renewable energy sources and maintaining our net-zero targets. By doing so, we can establish a stable and secure energy supply that is less susceptible to fluctuations in the international market.”

Notes to Editors
- Following a consultation process, Ofgem has revised the TDCVs, from October it will be reducing them from 2,900 kWh per annum for electricity to 2,700 kWh, and from 12,000 kWh per annum for gas to 11,500 kWh – these new numbers are now reflected in our forecast assumptions.
- The forecast figures for a typical dual fuel, direct debit consumer cannot be directly compared to the current level of £2,074, this is due to Ofgem’s revision of the TDCVs from October. If the current TDCVs were kept unchanged, the figures would be as follows:
