Ofgem has approved a deal intended to preserve the UK’s gas import capacity from Europe, OilPrice.com reported on 22 October, with IndexBox following up two days later. The two reports describe the same regulatory decision in near-identical terms. Neither outlet puts a figure on the cost, and neither says how the arrangement is structured. That matters, because the detail is where the household impact sits.
What Ofgem has actually approved
The decision concerns capacity on the gas interconnectors that link the UK to Belgium and the Netherlands. These pipelines matter in winter, when UK storage is thin and demand for heating peaks. The UK’s gas storage capacity is small relative to its neighbours, roughly a week’s worth of average winter demand, depending on how you count it, so import capacity is a form of insurance.
Ofgem’s approval keeps a commercial mechanism in place that preserves that capacity. OilPrice.com frames it as keeping UK gas import capacity from Europe; IndexBox uses the word “preserve”. Both descriptions point to the same thing: the regulator has signed off on an arrangement that stops capacity being withdrawn or repurposed in a way that would leave the UK short.
The regulator has not published a household-level cost estimate alongside the announcement. Nor have the outlets reported one. Treat any figure you see on social media with caution until Ofgem’s own documents are published.
Why it matters to a gas bill in Manchester
About 80% of a typical dual-fuel bill is set by wholesale gas prices, and those prices are set in a European market. When import capacity is tight, the UK pays a premium to attract gas. That premium feeds through to the Ofgem price cap with a lag of roughly three to six months.
The cap itself is currently set by Ofgem quarterly. A typical three-bed semi on a standard variable tariff uses around 12,000 kWh of gas and 2,900 kWh of electricity a year. A 10% move in wholesale gas prices translates to roughly £80–£100 on that household’s annual bill, depending on the season and the tariff mix. Keeping import capacity available does not cut that bill. It reduces the chance of a spike that would.
The catch is that security-of-supply measures are easy to announce and hard to price. If the arrangement involves a capacity payment to interconnector operators, that cost lands somewhere, either on suppliers, who pass it through, or on the network charges that sit inside every unit rate. Neither outlet reports the mechanism. Until Ofgem publishes the detail, homeowners should assume the cost is small but non-zero.
The bigger lever is still your own demand
Gas import capacity is a national issue. Your EPC rating is a household one. A three-bed semi rated EPC D typically spends £2,300–£2,700 a year on energy at current prices. Moving to EPC C through loft insulation, cavity wall insulation and draught-proofing can cut gas use by 15–25%, which is £250–£500 a year at today’s rates.
The grants exist. The Boiler Upgrade Scheme offers £7,500 towards an air-source heat pump in England and Wales. ECO4 funds insulation and heating upgrades for households on means-tested benefits or with a low EPC rating. The Home Upgrade Grant (HUG2) covers off-gas-grid homes in England. None of these are affected by the Ofgem decision, but all of them reduce the amount of gas you need to import in the first place.
What this misses is the timing. Installer lead times for heat pumps run to eight to twelve weeks in many areas. If you want a system commissioned before the coldest months, the quote needs to be booked now, not in December.
What to do before the heating season
Check your EPC first, it is free to look up on the gov.uk register, and it tells you which measures your home is eligible for. If you are on a low income or receive qualifying benefits, ask your energy supplier about ECO4 before approaching an installer directly. If you are off the gas grid, search the HUG2 eligibility checker on your council’s website.
For everyone else, the practical step is a heat pump quote through the Boiler Upgrade Scheme. The £7,500 grant is applied by the installer, so you pay the net cost. Get two quotes, ask for the MCS certificate number, and check the installer is registered before you sign.
Ofgem’s decision keeps the pipes open. It does not keep your bills down. That part is still down to the fabric of your home.
Frequently Asked Questions
Not directly. It is a security-of-supply measure covering interconnector capacity. Any cost is likely to be small and passed through supplier or network charges rather than appearing as a separate line on your bill. The price cap is set separately by Ofgem each quarter.
It reduces the risk of a supply-driven spike, but it does not set the price. Wholesale gas prices are set in the European market and depend on weather, storage levels and LNG availability. A typical three-bed semi still pays around £80–£100 a year more for every 10% rise in wholesale gas.
Check your EPC on the gov.uk register, then apply for ECO4 through your supplier if you receive qualifying benefits. If you are off the gas grid, check HUG2 with your council. For heat pumps, the Boiler Upgrade Scheme offers £7,500 in England and Wales and is claimed by your installer.
