UK electricity exports to France could raise household bills

The price cap will rise by £63 in October, the third increase this year. Now a new EU deal threatens to add another layer of cost to UK household bills by subsidising cheap electricity exports to France. The proposal, reported by The Sun, would see British taxpayers underwrite lower prices for French consumers while UK households pick up the tab through higher network charges and levies.

As The Sun reports, the deal could increase electricity flows across the interconnector between Britain and France, with UK consumers bearing the cost of making that power cheaper for French buyers. The exact mechanism is still under negotiation, but the principle is clear: UK households would subsidise electricity that lights homes in Lyon rather than London.

Who pays, and how much

Ofgem calculates that interconnector costs are already baked into household bills through network charges. A typical 3-bed semi using 3,100 kWh of electricity per year pays about £180 in network charges annually. If this deal adds 3% to those charges, that’s an extra £5.40 a year. But the impact could be larger if the subsidy extends to generation costs or capacity payments. The Energy Saving Trust estimates that any new levy on electricity exports could add £20-£30 to the average household bill by 2026.

The catch is that the UK already exports electricity to France when prices are lower here. But this deal would guarantee a minimum volume of cheap exports, even when UK demand is high. That means British households could be paying more for their own electricity to keep French prices artificially low.

What this means for your EPC and energy bills

For homeowners already struggling with high bills, this news is another reason to invest in energy efficiency. Every £1 spent on loft insulation saves about £0.15 a year on heating costs, according to the Energy Saving Trust. Solar panels can cut electricity bills by 40-60%, depending on orientation and roof size. A typical 4kW system costs around £6,000 and can save £400-£600 annually, more than enough to offset any export subsidy.

Improving your EPC rating from D to C can also reduce energy costs by 20-30% and increase property value by up to 5%. The government’s Boiler Upgrade Scheme offers £7,500 off a heat pump, which can cut heating bills by 20-40% compared to an old gas boiler. These upgrades pay back faster when grid prices rise.

What homeowners can do now

Households on standard variable tariffs should check if they can switch to a fixed-rate deal before the October price cap rise. But with fixed rates currently higher than the cap, many may be better off staying put. The real hedge is reducing consumption. Install smart meters to track usage, draught-proof windows and doors, and consider LED lighting, each saves £20-£40 a year.

For those with cash to invest, solar panels with battery storage offer the best protection against rising grid prices. A 5kWh battery adds about £2,000 to the system cost but can store cheap daytime solar for evening use, cutting grid imports by up to 80%. The typical payback period is 8-12 years, but with bills rising, it’s shrinking.

The deal is still under negotiation, with a final decision expected by early 2025. Households should monitor Ofgem’s announcements and consider energy efficiency upgrades now. Applications for the Boiler Upgrade Scheme are open until March 2027, but grants are first-come, first-served. Act before winter to lock in savings.
