Iran Conflict: Will Spain’s ‘Energy Shield’ Return? What You Need to Know About Your Bills
With tensions in the Middle East driving oil and gas prices to 2026 highs, the Spanish government is under pressure to slash VAT (IVA) once again. We look at what’s happening and how you can protect your pocket.
By uSwitch Energy Experts | Published: 10 March 2026
Just as the Spanish energy market seemed to be stabilizing, the outbreak of conflict in Iran on February 28 has sent shockwaves through the pumps and the power grid. For many households in Spain, the timing couldn't be worse: January 1, 2026, marked the official return to the standard 21% VAT on electricity and gas.
But with diesel prices now creeping toward the "psychological barrier" of €2.00 per litre and electricity prices jumping 57% in a single week, the calls for a "War Response Plan 2.0" are growing louder.
Is the IVA (VAT) Drop Actually Going to Happen?
Economy Minister Carlos Cuerpo has confirmed that the government is "prepared to react," just as they did during the 2022 energy crisis. However, a tax drop isn't automatic. Here is what needs to happen:
- The €45/MWh Trigger: Under current rules, if the average monthly wholesale electricity price stays above €45/MWh, the government has the legal green light to lower VAT back to 5% or 10%.
- The Royal Decree: The Council of Ministers must pass a new Real Decreto-ley. We expect a decision by the end of March, with changes likely appearing on your April 1st bill.
- The Fuel Cap: Consumer groups like FACUA are currently lobbying for a "price cap" that would prevent energy companies from making higher profit margins than they did before the conflict began on February 28.
Why Are Prices Rising Now?
The conflict is centered near the Strait of Hormuz, a narrow waterway that carries 20% of the world’s oil and liquefied natural gas (LNG).
- The "Renewable Paradox": Spain generates over 50% of its power from sun and wind, but when the sun sets, we rely on gas-fired plants. Because gas prices have spiked by 30% since the conflict began, your evening electricity rates are bearing the brunt.
- Petrol Pump Pain: Average petrol prices in Spain have already hit €1.62, while diesel has jumped to €1.66 in some regions like Catalonia and Madrid.
3 Ways to Protect Your Bill Today
While we wait for the government to act, there are steps you can take right now to stop your costs from spiraling:
- Shift Your Usage (The "Solar Window") If you are on the regulated PVPC rate, the price difference between midday and evening is currently massive. Try to run your dishwasher or washing machine between 11:00 AM and 4:00 PM, when Spain’s solar production is at its peak and wholesale prices are lowest.
- Lock in a Fixed Rate In 2022, many people who stayed on "Variable" rates saw their bills triple. If you want peace of mind while the Iran conflict continues, now is the time to compare Fixed Rate tariffs. Locking in a price today protects you if the conflict escalates and gas prices double again.
- Claim Your ‘Bono Social’ Over 1.7 million Spanish households are eligible for the Social Bonus, which offers discounts of up to 57.5%. If you are a large family, a pensioner, or have a low income, make sure you have applied through your "Comercializadora de Referencia."
The uSwitch Verdict
The next 14 days are critical. If the government announces an emergency IVA reduction, it could save the average household over €200 a year in taxes alone. However, waiting for the government isn't a strategy.
Expert Tip: “Don’t wait for the BOE (State Gazette) to change the law. Check your last bill today. If you are paying more than 0.15€ per kWh on your energy term, you are likely overpaying.”
