Typical domestic consumption values (TDCVs)
Typical domestic consumption values are Ofgem's yearly usage figures for a typical home, 2,500 kWh electricity and 9,500 kWh gas from 1 July 2026.
Typical domestic consumption values (TDCVs) are Ofgem's estimates of how much gas and electricity a low, medium and high use home consumes in a year. Ofgem uses them to turn the energy price cap rates into the headline "typical bill", and suppliers and comparison sites use them when your own usage is unknown.
The figures from 1 July 2026, from Ofgem's decision of 27 May 2026 (checked 27 September 2026), in kWh a year:
- electricity, single rate: low 1,600, medium 2,500, high 3,800;
- electricity, multi-rate such as Economy 7: low 1,900, medium 3,400, high 6,100;
- gas: low 6,000, medium 9,500, high 14,000.
They fell from 2,700 kWh and 11,500 kWh, so the headline bill fell without prices falling.
Example: at the average Direct Debit cap from 1 October 2026, medium electricity costs £658.00 in units (2,500 × 26.32p) plus £200.13 in standing charges (365 × 54.83p), and medium gas £757.15 plus £108.33. The total, £1,723.61, is Ofgem's £1,723 typical bill.
