Because the Heart East battle intensifies and oil and gasoline costs swing wildly, the United Kingdom has observed renewed calls to drill extra within the North Sea. The argument is easy: if Britain produces extra of its personal oil and gasoline, family power expenses must fall.
However our research suggests the impact could be minimum. Despite the fact that the United Kingdom maximised North Sea extraction and returned revenues at once to families, the aid in power expenses could be at maximum a modest £82 in line with yr – a long way smaller than the financial savings anticipated from accelerating the shift to renewable power.
In truth, a sooner transition clear of gas-powered electrical energy may lower family power expenses by means of thrice up to maximising North Sea oil and gasoline.
Why UK power expenses are so top
A normal UK family has a unmarried “dual fuel” invoice overlaying each electrical energy and gasoline. This will also be divided into a number of other parts.
The biggest percentage is the wholesale value – the fee providers (the corporate named in your invoice) pay for electrical energy and gasoline – which accounts for roughly 41% of the invoice. The remainder covers the prices of working and keeping up power networks (23%), working prices and money owed (15%), coverage prices equivalent to environmental and social levies (12%) and VAT.
On the wholesale stage, the United Kingdom does now not constantly pay greater than different Ecu nations. At more than a few issues since 2022, nations equivalent to Italy and Germany have confronted an identical or upper wholesale prices.
But UK families nonetheless pay one of the crucial very best retail electrical energy costs in Europe. That’s on account of how the electrical energy marketplace works.
Closing yr, about 27% of UK electrical energy used to be generated by means of gasoline energy vegetation like this one in North Wales.

In Britain, the wholesale electrical energy worth is in most cases set by means of the most costly generator had to meet call for. That generator is steadily a gas-fired energy station. Because of this, electrical energy costs have a tendency to upward thrust and fall with gasoline costs – even if a lot of the electrical energy is produced by means of less expensive assets equivalent to wind or sun.
Fuel additionally dominates house heating – 85% of UK families nonetheless depend on gasoline boilers, excess of in maximum similar nations
This makes UK families extremely uncovered to swings in world fossil gasoline costs. Fuel costs are set on world markets, which might be closely uncovered to geopolitical shocks, as observed each in 2022 after Russia’s invasion of Ukraine and once more lately.
Britain’s poorly insulated houses – a few of the least power environment friendly in northern Europe – compounds the issue. This implies families eat extra gasoline to succeed in the similar stage of heat.
Why extra North Sea drilling wouldn’t lower expenses
Generating extra oil and gasoline within the North Sea would now not create the United Kingdom’s “own special supply”, nor may its worth be set particularly for UK electorate.
That’s as a result of any new manufacturing could be bought on world markets at world costs. The United Kingdom merely doesn’t be able to extract, refine and use oil all on its own even though it sought after to – some world buying and selling will at all times be essential.
The one manner North Sea extraction may cut back family expenses is thru executive revenues. Taxes and levies on oil and gasoline income – the so-called fiscal “take” – may in concept be redistributed to families.
To discover this risk, we modelled a situation by which the United Kingdom maximised North Sea oil and gasoline and used all revenues accumulated to subsidise decrease power expenses.
Even underneath the ones assumptions, the impact could be restricted. Family expenses would fall by means of between £16 and £82 in line with yr. That’s more or less 1% to 4.6% of the present moderate family power invoice of £1,776, in line with UK regulator Ofgem.
Larger financial savings from renewables
A special coverage path – one who reduces the function of gasoline in electrical energy manufacturing – produces a lot greater financial savings.
If the cost of electrical energy used to be set by means of less expensive renewable power reasonably than by means of gasoline, our research suggests families may save £105 to £331 in line with yr thru decrease wholesale power prices.
This is more or less thrice greater than the “maximise oil and gas” situation.

Importantly, those financial savings would even be routine. As soon as electrical energy costs are much less tied to unstable gasoline markets, and as a substitute are set by means of less expensive and infinitely to be had assets – wind and solar – families get advantages annually.
Financial savings may well be nonetheless upper if the construction of electrical energy expenses have been rebalanced. At this time, many coverage prices – together with enhance for renewables – are added to electrical energy expenses reasonably than funded thru common taxation.
If the ones coverage prices have been moved into common taxation, as introduced within the executive’s autumn 2025 spending assessment, the common family may save up every other £110 or so every year. In our renewables situation, that might carry the whole financial savings to about £441 in line with yr.
Transferring coverage and gadget prices from expenses onto common taxation is one strategy to make power prices fairer and extra egalitarian. That’s as a result of power expenses take a bigger percentage of source of revenue from decrease source of revenue families whilst taxes higher mirror talent to pay.
Our research used oil and gasoline costs in January 2026, previous to the breakout of the US-Israel battle on Iran. In different phrases, ours is a conservative situation that assumes fairly beneficial prerequisites for fossil fuels. If world costs upward thrust additional, some great benefits of renewable power would change into even higher.
Lowering publicity to fossil gasoline shocks
Contemporary historical past illustrates how expensive dependence on fossil fuels will also be.
Analysis by means of our colleagues at Oxford Smith Faculty discovered that if the United Kingdom had moved clear of uploading Russian oil and gasoline after its 2014 invasion of Crimea, it will have stored about £22 billion in power prices right through the fee spike after the invasion of Ukraine in 2022.
In a similar fashion, had the United Kingdom followed the “balanced net zero” pathway proposed by means of its authentic advisory Local weather Trade Committee, it might steer clear of spending round £70 billion on crude oil and herbal gasoline between 2022 and 2030.
Nowadays’s power disaster merely reiterates this argument: if the United Kingdom used to be much less reliant on oil and gasoline lately, it will be in a significantly better financial place.
The easiest way to stay power expenses low in the end is to scale back dependence on gasoline altogether. That suggests increasing renewable era, making an investment in power garage and grid infrastructure, bettering house insulation and electrifying heating thru applied sciences equivalent to warmth pumps. Strengthen for prone families can be a very powerful right through the transition to a lower-carbon power gadget.
Our findings refute hypothesis that draining the North Sea of all oil and gasoline would considerably decrease expenses and make the United Kingdom power safe. Despite the fact that additional fossil gasoline extraction went forward and all tax revenues have been returned at once to shoppers, the financial savings for shoppers could be modest. In the meantime the United Kingdom would stay uncovered to geopolitical shocks and be economically worse off.
Staying the direction on blank power would now not handiest save families thrice as a lot cash however render the United Kingdom really power safe for generations to come back.
