Households in Great Britain ‘could owe energy suppliers £7bn by end of year’

Energy industry representatives have projected that household energy debt in Great Britain may accumulate to £7bn by the conclusion of the year, driven by anticipated increases in gas and electricity costs during the approaching winter season. Current figures show that domestic energy arrears have already climbed by approximately £500m over the preceding year, reaching a record £6bn at the end of June, with ongoing geopolitical tensions continuing to influence global gas market prices.

The regulator is expected to confirm a 4% increase to the energy price cap affecting millions of households, effective from October. Industry trade association Energy UK has cautioned that this rise will substantially exceed the relief provided by the government’s plan to reduce VAT on electricity bills from that same month, which is estimated to save households an average of £45 annually. The regulatory adjustment is expected to result in typical household energy bills reaching approximately £1,729 per year based on direct debit payments, with electricity rates rising to 26.57p per kilowatt hour and gas charges climbing to 7.90p under the new cap structure.

Energy UK’s chief executive has called for more comprehensive policy responses to address rising energy costs, advocating for a permanent social discount tariff program rather than temporary relief measures. The group contends that current approaches fail to adequately support vulnerable households and ultimately prove more expensive overall. Global wholesale gas sourcing costs represent the primary factor driving the projected price increase, though expenses related to upgrading Great Britain’s energy network infrastructure are also contributing to elevated energy costs.

Energy UK’s debt estimates exceed official figures reported by the regulator Ofgem by approximately £1bn, as the trade association counts unpaid bills after 30 days of nonpayment while regulators typically measure debt only after 90 days have elapsed. The difference between these accounting methods results in an additional cost of roughly £50 annually, or approximately 3% extra, being distributed across typical household bills to account for unpaid energy charges.
