Ofgem has today announced the January Default Tariff Cap (price cap) at £1,928 a year for a typical dual fuel consumer1. This is a 5% increase from October’s cap set at £1,834 a year.
Escalating wholesale market volatility, triggered by geopolitical factors such as disruptions to the Finnish Balticconnector, the Israel-Hamas conflict, and industrial action at gas production facilities in Australia, has collectively driven up energy unit prices.
Dr Craig Lowrey, Principal Consultant at Cornwall Insight said:
“Amid the cost-of-living crisis, the last thing households need is a rise in energy bills – especially going into the winter months. Earlier this year, it seemed like the outlook for consumer bills was improving, with bills gradually falling after the dramatic rises post Russia’s invasion of Ukraine. However, as is often the case in the energy market, new challenges have arisen, and our reliance on foreign energy has once again left the UK vulnerable to price increases caused by events around the globe.
“With little in the way of direct energy bill support coming out of the Autumn Statement, consumers are likely to look at lowering energy usage to counteract high bills – particularly given that bills remain well above their historic averages. However, as we move through 2024, it’s not just the persistently high unit costs that will be a worry; the looming rise in electricity standing charges from April adds another layer to the equation.
“Given that standing charges for gas and electricity make up about 16% of overall household bills, even those who use less energy might find themselves grappling with escalating costs. Ofgem’s recently announced review acknowledges this imbalance, but it’s a complex issue. Redistributing these charges might assist some but could harm vulnerable individuals in less energy-efficient homes or those with higher energy needs.
“Fundamentally, the solution extends beyond tweaking energy bills, given the underlying cause of rising energy bills over the last 24 months. We need a long-term strategy that reduces our dependence on imports of energy – particularly gas. By investing in domestic renewable energy sources, we can start to break free from the international market fluctuations and stabilise our energy prices for homes and businesses alike.”
