TUR natural gas April 2026: what changes in your bill and what to do

Key data

Self-employed workers and SMEs that maintain their gas contract with a last resort supplier will see their bill modified from April 1, 2026. The Dirección General de Política Energética y Minas has published the quarterly update of the Tarifa de Último Recurso (TUR) for natural gas through the Resolución de 27 de marzo de 2026 (BOE-A-2026-7193).

This tariff acts as a reference price and protection mechanism for households and small businesses that have not yet moved to the free market. If your business is still on the TUR, what you pay for gas changes right now.

What does this regulation establish?

The TUR is the maximum regulated price that last resort suppliers can charge their customers. It is reviewed every quarter and set by the Dirección General de Política Energética y Minas. It is not a market price: it is a state-controlled price designed to protect smaller consumers.

This resolution publishes the new TUR values applicable from April 1, 2026. The key points it establishes are:

• Mandatory quarterly update of natural gas TUR values.
• Immediate application from April 1, 2026 to all contracts under this tariff.
• The tariff acts as a reference price and protection for households and small businesses.
• Consumers on the TUR are those who have not contracted supply in the free market.
• Validity is quarterly, with the next review expected in July 2026.

The resolution does not publish the exact numerical values of the new TUR in the official summary. To consult the specific amounts by bands and consumption, you must access the full text in the BOE (BOE-A-2026-7193).

Economic and operational impact

The direct impact is on the gas bill of any business or self-employed worker still on the regulated tariff. As this is a quarterly review, the change is immediate: there is no adaptation period.

There are two possible scenarios depending on the variation applied:

• If the TUR rises: your gas bill increases from April 1. In that case, comparing with the free market could generate real savings.
• If the TUR falls: your bill is automatically reduced. Even so, it is worth checking whether the free market offers more stable conditions in the long term.

The operational impact is minimal: no action is required for the new price to be applied. The last resort supplier applies it automatically. The relevant business decision is whether to remain on the TUR or switch to the free market.

Who is affected?

• Self-employed workers with a gas supply at their premises or business under a regulated tariff.
• SMEs with low consumption that have not contracted in the free market and remain with a last resort supplier.
• Domestic consumers (households) on the TUR, especially vulnerable consumers.
• Small businesses (hospitality, retail, services) that have never changed supplier and maintain the default regulated contract.

This does not affect companies that already have a gas contract in the free market with a private supplier at an agreed price.

Practical example

Imagine a small café with a regulated gas contract (TUR). From April 1, 2026, its bill automatically reflects the new values published in this resolution, without the owner having to do anything.

If the TUR has risen compared to the previous quarter, the owner will pay more for the same consumption. At that point, they have two options: accept the new price or contact free market suppliers to compare offers. If the TUR has fallen, the saving is also applied automatically.

The key for this type of business is not to assume that the TUR is always the cheapest option. Each quarter, when the new resolution is published, it is an opportunity to review whether the current contract remains competitive against the free market.

What should businesses do now?

1. Identify whether your gas contract is TUR or free market. Check your latest bill: if the term "comercializadora de último recurso" or "tarifa regulada" appears, you are on the TUR and this resolution directly affects you.
2. Check the new TUR values in the BOE. Access the full text of the Resolución BOE-A-2026-7193 to find out the exact amounts applicable from April 1, 2026.
3. Compare the TUR with free market offers. Request quotes from at least two free market suppliers. Depending on the variation applied, it may be more or less competitive than the TUR.
4. Decide whether to switch supplier. If the free market offers a lower price and stable conditions, switching supplier is a straightforward and cost-free process. If the TUR is cheaper, keep your current contract.
5. Schedule the next review. The TUR is reviewed every quarter. Mark the next update in your calendar (expected July 2026) to repeat this comparison and not miss savings opportunities.
