Ofgem has proposed to update its standard consumption profiles for households to reflect continued falls in electricity usage.
The typical domestic consumption values (TDVCs) are used to estimate energy bills, compare prices and assess the impact of policy and regulatory decisions. Ofgem is consulting on several amendments as part of a routine review.
The regulator plans to keep the values for gas usage unchanged but intends to raise its estimate of the proportion of electricity consumed during peak hours by households with an Economy 7 meter.
Ofgem said the proposed adjustments would lower its view of the typical dual fuel energy bill for a medium-sized household paying by direct debit by £36 to around £1,142.
Revised values and impact on bills
Note: Profile Class 2 households consist predominantly of those with Economy 7 and Economy 10 meters.

The regulator said it was not currently planning to update the benchmark consumption values used to calculate the price cap on default tariffs to keep them aligned with the TVDCs.
The profiles were last revised in 2017. Ofgem expects to introduce the new values from 1 April 2020 and has given stakeholders until 18 November 2019 to submit feedback on its minded-to decision.
