The regulatory entity of energy services (ERSE) confirmed a 1.5% update on the price of natural gas from October 1, 2025. This change will have a direct impact on the monthly invoice of most domestic consumers, with increases that oscillate between 0.36 and 0.21 euros, depending on the consumption profile.
The increase is part of the annual review of regulated tariffs, and covers both clients in the regulated market and those who have a contract in the liberalized market.
Non -regulated market impact
According to ERSE, domestic consumers on the regulated market summer average increases due to the consumer level. For a childless couple, with annual consumption of 1,610 kWh, the monthly invoice will go to 16.38 euros, more 0.36 euros than in September. In the case of a couple with two children, with an annual consumption of 3,407 kWh, the new invoice will be around 30.73 euros, representing a rise of 0.21 euros.
These values serve as a reference for regulator-used profiles and allow you to anticipate the practical impact of the tariff review.
Liberalized market: What to expect?
For consumers with a contract in the liberalized market, final prices vary according to the trader and the contractual offer. However, according to ERSE, there is a common factor for all: the so -called network access fares.
These regulated rates are applied to all consumers, regardless of the supplier, and represent the costs associated with the use of gas network infrastructures. In October, new values come into force, influencing invoices, even in the liberalized market.
Increased low pressure
According to the same source, for low pressure consumers with consumption up to 10,000 m³ per year, covering the generality of household consumers, the increase in network access tariffs will be 0.34 cents of euro per kWh.
This amount will be reflected in the tariff updates by traders, who tend to review their offers whenever new regulated tariffs come into force.
We recommend:
Lower climb for non-domestic consumers
In the case of high pressure consumers (such as industrial units), medium pressure or low pressure with consumptions greater than 10,000 m³ per year, the rate variation will be lower.
ERSE estimates between 0.03 and 0.15 cents of euro per kWh, depending on the consumption profile and pressure level.
The figure provided by the regulator shows the evolution of these rates since 2021, reflecting a pattern of moderate variations in recent years.
How to reduce the impact of the climb?
Although the increase seems unintentionally, it is possible to apply strategies to mitigate its effect. Among the suggested measures is the improvement of gas equipment efficiency, such as replacing older heater with models with energy or higher energy classification.
It is also advisable to adjust the hot water temperature, reduce the time of use of the appliances and avoid heat loss through windows and poorly isolated doors.
Check your echelon and consumption
Many consumers are unaware that they may be in a tier of consumption maladjusted to their real profile. Confirming from the supplier and requesting the update of the level can reduce unnecessary fixed costs.
Regularly consult the invoice and identify cost components (energy, fees, VAT) also helps to realize where the largest charges are.
It pays to change supplier?
If you are on the liberalized market, comparing tariffs remains an effective savings. The change of traders is free, without interruption of supply and can be done online.
The ideal is to use independent simulators that include the updated values of network access fares and allow to compare real prices.
