Tips for switching gas companies with Reformia
The time it takes to switch gas companies usually does not exceed 20 days. Keep in mind that the old company must close its billing cycle.

1. The starting point is to compare what different suppliers offer. There are many companies in the market and sometimes the variations in tariffs are significant.

2. You need to consider the differences between the free and regulated markets. In the regulated market, tariffs are fixed and reviewed every three months. Depending on how the energy market evolves, this is an aspect worth evaluating.

3. In the case of free market suppliers, it is important to look at all the details, both the fixed term price and the kWh price. Sometimes one of these aspects is very economical and distracts attention from the other, which may not be.

Steps to switch gas providers
The time it takes to switch gas companies usually does not exceed 20 days. Keep in mind that the old company must close its billing cycle.

1. Compare rates from different gas suppliers
Before switching gas companies, it's essential to compare rates available in the market. Review offers from different suppliers to find the most economical option based on your annual consumption. This initial step can save you between 50 € and 200 € annually on your gas bill.

2. Gather your personal documents and supply information
Prepare your personal documentation (ID, address) and current supply data (contract number, meter details). These documents are mandatory to request the company change and will prevent delays in your gas contract migration process.

3. Request the switch with your new provider
Contact your new gas supplier to formally request the company change. The cost of switching companies is typically free (0 €), although if you have a contract commitment with your current provider, you may face a penalty of up to 75 €. The new company will manage all necessary documentation.

4. Wait for the billing cycle to close with your current provider
After requesting the change, you must wait until your current gas company's billing cycle closes. This period typically lasts between 1 and 2 months and is necessary to properly finalize your previous contract without additional costs.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Current contract type
The cost of switching varies depending on whether you have a fixed, variable, or indexed contract. Contracts with early termination penalties can generate additional costs that impact your total switching budget.
Gas supplier chosen
Each gas company in Spain offers different rates and conditions. Some apply bonuses for switching suppliers while others may charge commissions, directly affecting your final cost.
Geographic location and distributor
The local distributor that manages the gas network in your area can influence administrative timeframes and costs. Rural areas may have more complex procedures than urban areas.
Technical inspection of installation
If the new company requires an inspection of your gas installation to verify its safety, this can generate additional costs that vary depending on the complexity of your supply system.

Which gas company should you switch to?
The time it takes to switch gas companies usually does not exceed 20 days. Keep in mind that the old company must close its billing cycle.
Free market suppliers have absolute authority to determine their tariffs, not only in price but also in associated services or billing type. Therefore, in the free market it is possible to choose between flat-rate tariffs or tariffs based on actual consumption. There may also be tariffs that combine gas and electricity if the supplier operates in both sectors.
How to switch gas companies? Steps to follow
The time it takes to switch gas companies usually does not exceed 20 days. Keep in mind that the old company must close its billing cycle.
Moreover, within the free market there are countless suppliers, which means greater choice and the ability to take advantage of offers and promotions that appear fairly frequently. It should be noted, however, that sometimes these offers come with lock-in periods.
Another aspect is access charges, which affect billing. There are four:
- RL 1: for consumption of less than 5,000 kWh/year.
- RL.2: consumption between 5,000 kWh/year and 15,000 kWh/year
- RL. 3: consumption between 15,000 kWh/year and 50,000 kWh/year
- RL. 4: consumption above 50,000 kW/year.
To switch gas companies, the first step is to search for offers from gas suppliers. There are numerous companies and competition drives them to bring the most attractive products possible to the market.
After that, it is worth carefully analyzing not only the tariffs they apply, but also the conditions. This would be the case, for example, of lock-in periods or associated services that involve a cost, such as boiler maintenance.
Once you have chosen the supplier that offers the tariffs that best suit your needs, the next step is to contact them by phone or online. Some also have physical offices where you can complete the process.
- TUR 1: for users with consumption equal to or below 5,000 kWh/year
- TUR 2: for consumption between 5,000 and 15,000 kWh
- TUR 3: for consumption between 15,000 and 50,000 kWh
- TUR 4: for consumption above 50,000 kWh/year, specifically for homeowner associations.
