What happens if your bill includes days before and after 1 June?

This is one of the most frequently asked questions. Even if a portion of the energy you consumed was used before 1 June, the VAT rate applied will depend on the invoice issue date.

In general, if the bill is issued in June, it will usually already include the 21% VAT rate, even if it covers consumption from earlier periods.

In addition, the impact is not the same in all cases:

• If you are on a fixed-rate tariff, the impact of the VAT increase in June is already partially absorbed, as the energy price remains stable throughout the contracted period.
• If you are on the regulated tariff (PVPC), you will immediately feel the impact of the VAT change in June, as the price varies depending on the market.

Why are the energy tax breaks ending now?

Although the measures were initially expected to remain in place until 30 June, the regulation included a key condition: their continuation depended on the evolution of energy CPI.

With energy prices moderating in recent months, the Government has confirmed the end of the tax breaks from 1 June 2026.

In other words:

• If energy inflation had remained high, the measures could have been extended.
• As prices have stabilised, the temporary mechanism approved during the energy crisis is being phased out.

What you can do before 30 June to prepare

Although tax changes are beyond the consumer’s control, there are still several decisions that can help reduce the impact on your next bill.

Review whether your current tariff is still the right one

Energy habits change constantly due to remote work, electric vehicles, new appliances, or simply different household routines.

That is why the weeks leading up to June can be a good time to check:

• Whether your tariff is still competitive.
• Whether you have the right contracted power.
• Whether you are actually taking advantage of cheaper hours.

If you have an electric car, try to charge it early

If you use an electric vehicle, planning some of your charging sessions before June can help you still benefit from the period with reduced taxation.

This is especially smart if you are planning long road trips or expect to drive more frequently during the summer.

Review your gas tariff before the next winter

Although gas consumption usually drops in summer, this can be a good time to review your conditions and prepare in advance for the colder months, especially if you use gas for heating, cooking, and hot water.

Follow efficient consumption habits

Taxes aside, small daily habits continue to make a meaningful difference in energy consumption:

• Adjusting usage schedules.
• Avoiding phantom consumption.
• Checking air conditioning temperature settings.
• Improving the efficiency of some of your appliances.

These small adjustments often have a bigger impact on your monthly bill than expected.

 FAQ

Will electricity VAT definitely increase on 1 June?

Yes. Following the latest energy CPI data, the Government has confirmed that the temporary tax breaks will expire on 1 June 2026.

How much could my bill increase?

It depends on your consumption and whether you have electricity only or both electricity and gas.

For an average household with both supplies, the combined impact of VAT and the IEE could be approximately an extra €10 to €20 per month.

Does the Social Bonus also end on 30 June?

No. The Social Bonus operates under separate regulations and is not directly linked to the temporary tax measures applied to VAT and the IEE.

You can find updated information about the Endesa Social Bonus here.

Can I change my tariff now so that the new price applies starting June?

Yes. In most cases, switching tariffs is free and there is no commitment period.

If you request the change before the end of May, the new price may apply in your very next billing cycle.

Will the IEE also increase in June?

Yes. The Special Electricity Tax is expected to return to its usual rate of 5.11%, up from the 0.5% rate applied over the past months.

While it may be less visible than VAT, it also directly affects the final bill amount.

Although taxes are only one of the factors influencing the final electricity bill, reviewing your tariff and adjusting your consumption habits can help you better manage the upcoming changes in June. Endesa will continue to provide updates on any regulatory changes affecting electricity and gas bills.
