[Article updated in October 2024]

If you're looking to save on your gas bill, you've probably considered switching to a regulated rate or the free market. Making the right decision between the two options is key to reduce your business expenses.

In this article, we explain the differences between the regulated market and the free market, and how to make the change of Gas rate in a simple way to maximize your savings.

Types of gas tariffs

There are two types of gas rates: the rates of the regulated market and the rates of the Free market. The main difference between them lies in who sets the price and how these rates are updated.

Free market

In the free market, gas rates are set by the trading companies themselves. This type of rate allows companies to offer personalized pricing, discounts, or additional promotions.

Advantages of the free market:

  • Personalized offers and flexibility.
  • Possibility of additional services such as maintenance.

Disadvantages of the free market:

  • Prices may be higher compared to the regulated rate.
  • Less transparency about how the price is set.

Regulated market

In the regulated market, rates are set by the government through the Last Resort Fee (TUR). This system guarantees more stable and transparent pricing, with updates every quarter. It's a very attractive option for those looking for security and significant savings on their bill.

Currently, there are four retailers that offer the TUR for gas: Gas & Power Regulated Trading Company, Curenergía, Baser COR, Energy XXI.

Advantages of the regulated market:

  • Price set by the government.
  • Transparency and control over updates.
  • In general, it's usually cheaper than the free market.

Disadvantages of the regulated market:

  • Less flexibility in contracts.
  • It does not include additional services such as maintenance.

Which gas rate is best? Differences

When you wonder if it's better the free or regulated gas market, you must take into account several factors such as your consumption, price stability and whether you value having additional services or a lower price more. Here are the main differences:

So what is the best gas rate?

If you're looking to save on your gas bill, the regulated rate (TUR) is usually the best option, especially in periods of price volatility. However, if you prefer to have additional service options or customize your contract, the free market may offer you greater flexibility.

Therefore, Is the regulated rate (TUR) or a free market offer better? Currently, the Rate of Last Resort (TUR) remains, in most cases, the most affordable option available.

Although there are occasional exceptions, TUR is usually the best option for most homes. By comparing the rates available on the free market with the regulated TUR rate, it is estimated that users who opt for the TUR can save up to 15% on your annual gas bills. This translates into a savings of more than 100 euros per year for an average household with a consumption of 9,000 kWh. These savings can be even more significant for households with higher consumption.

For their part, homeowners' communities, in particular, should pay special attention to their contracted gas rates. Accessing the TUR regulated rate can mean significant savings in the gas bill in these communities, where consumption is usually much higher than that of an individual home. Revising and changing the TUR rate can be a strategic decision to reduce heating and hot water costs in shared buildings.

The need for greater transparency in gas rates

A key aspect for consumers is transparency in rate information. Users must have clear access to prices and know how much they are going to pay for a service as basic as gas. In this regard, marketers have a responsibility to comply with certain reporting obligations.

From associations such as Consumer and User Organization (OCU) Marketers are required to:

  1. Make all your rates public, including those that are no longer contractable, so that consumers can compare options in a clear and transparent manner.
  2. Improve communication with customers, informing more clearly about prices and providing clear estimates of the invoices that users will receive.
  3. Permanently reduce VAT on gas and electricity, a measure that was temporarily implemented, but which should become something definitive to alleviate consumers' energy costs.

With these measures, it seeks not only to allow users to choose the best option for their needs, but also to avoid surprises in bills and to ensure that gas companies act clearly and honestly.
