How to choose your energy supplier

#1 - The price of electricity: fixed or indexed?

What is the difference between fixed-price electricity and indexed tariffs? In the fixed price electricity offer, the price of the kWh remains unchanged during the duration of the contract. This duration can be from 1 to 2 years, or even more. This means that even if the regulated tariff increases, the price per kWh remains fixed for the period of the contract.

In an indexed price offer, the price per kWh can be up to 17% cheaper than the regulated price per kWh. Thereafter, the rate follows the fluctuations in the price of the regulated kWh, both up and down.

#2 - Customer service

It is important to know in advance the services offered by the customer service. How is the billing done, how to get in touch with the customer service agents, how to transmit the consumption indexes, is it possible to go through an online platform, etc.? In any case, beware of offers without a telephone customer service. In case of emergency or dispute, it is sometimes complicated to communicate only by email or chat.

#3 - Additional costs

Suppliers often apply additional charges, which are not always known in advance. The existence of a security deposit, penalties in case of unpaid bills, labor costs related to the installation, all these additional costs can increase the final bill.

#4 - The types of offers

With the arrival on the market of new energy suppliers, you will have a wide choice between the types of services offered by the operators: complete offers, green electricity, natural gas in network, gas in tank or in bottle, etc. Take the time to compare the terms and conditions of the offers before taking out a new subscription.

In any case, find out beforehand about your rights in the event of a service malfunction or billing problem. The contractual responsibility of the operator must be clearly defined, in order to prevent any type of dispute.

#5 - The price of energy

By going through a price comparator, you will already have a global overview of the price trends: regulated rates, off-peak or full hour prices, indexed rates... Take the time to compare the price of the kWh practiced by the different suppliers, to have a first estimation of your energy budget.

Changing electricity supplier: how does it work?

For private individuals, changing energy supplier is a simple and free process that can be carried out at any time. The customer can choose a new supplier as often as he wants. However, they must inform their supplier of the planned termination date by telephone or letter. No notice period is required.

The termination procedure depends on the subscriber's situation: if the subscriber changes provider, the migration formalities can be taken care of by the new provider. During the transfer period, the old provider continues to supply electricity until the new subscription is activated. In the case of a move, the old contract must be terminated and replaced by a new subscription.

It is advisable to find out about the types of offers and terms and conditions offered by each supplier before signing a new contract. As the subscription with an energy supplier is completely free, the customer can subscribe with a second operator if he wishes.

The different types of energy suppliers

Since the opening of the energy market to free competition, the number of energy suppliers has increased significantly. What kind of services do these energy players offer?

Electricity and gas suppliers

Electricity and gas suppliers offer traditional or specifically ecological offers, with wind/solar electricity and green gas (biogas). Thedual energy contract has many advantages: a single subscription, consolidated billing, etc.

However, signing up with a single supplier can have its drawbacks. In case of a service failure or disagreement, you may find yourself locked in. Some complete offers are not necessarily competitive: electricity may cost more than gas, or vice versa.

Gas suppliers

These suppliers offer solutions that are closer to the needs of users, in the form of propane gas in bottles or tanks. The customer can also choose to connect to a natural gas distribution network. Among the strengths of this type of offer are the competitive prices of natural gas, linked to a fairly stable price. Another advantage is that this fossil fuel emits no dust during its combustion.

However, there are still some disadvantages: propane gas must be stored in special, rather unsightly equipment. The tank can be buried, but this operation requires some prior arrangements.

Alternative energy suppliers in green electricity

Alternative energy suppliers in green electricity are committed to the environment. One of the positive points of this type of offer is the absence of pollution generated by renewable energy.

However, the cost of production facilities is quite high. Indeed, the solar or wind devices do not produce electricity permanently. In order to be used in an optimal way, the electricity produced must be stored, through special infrastructures that can be quite expensive.

Natural gas or electricity, what to choose?

Natural gas

Natural gas is interesting on many points: first of all, on the economic level, this energy is less expensive than electricity. It is also environmentally friendly, with little pollution and its combustion generates little CO2. Gas can be used for cooking, for heating the house and for domestic hot water needs.

However, gas has a major drawback: this fossil fuel is limited. The world's natural gas resources are dwindling, due to a sharp increase in global consumption in recent years.

Electricity

Among the advantages of electricity, several points can be highlighted: stable price, adjustable consumption, possibility to use low energy consumption equipment... Another advantage is that green electricity solutions limit gas emissions.

However, some disadvantages are worth mentioning: electricity storage is necessary to cope with peaks in consumption. This solution requires the use of often expensive equipment. Shortages or power surges can also occur during peak energy consumption periods.

Verdict

Gas and electricity offer multiple advantages in everyday life. Electricity can be used for cooking, switching on appliances that require high power, lighting, etc. Gas is a good solution for home heating and hot water supply.

Reasons to switch energy suppliers

Free choice of plan

Energy providers have every reason to offer a unique selection of plans. And each new provider may offer a different and more attractive plan than the last.

Customer Service

As a business, providers need to be more than just an energy supplier that sends electricity through your lines and a bill at the end of each month. Normally, you have the opportunity to look for a team of customer service managers and technicians that you really enjoy working with.

Transparency and lower cost

Customer satisfaction and fee transparency is the best possible approach for energy providers. Prices are reasonable and billing elements are transparent. In fact, you can even choose based on how the bills look and how transparent each design is to you. Alternative suppliers can offer cheaper prices than traditional suppliers. They set their rates with reference to the regulated tariffs. This means that the price of electricity or gas does not change during the entire contract period. And for the alternative suppliers who propose, free tariffs apply prices which do not refer to the regulated tariffs and which can evolve at any time. Only the electricity suppliers use this pricing. Generally, a reduction of 10% compared to the price of the KWh is noted with these suppliers.

Ecological

Some energy suppliers build their corporate culture and reputation around environmentally friendly practices. Recycling office and use of recycled products, rainwater harvesting for watering floors and choosing to work with environmentally friendly business partners.

More control

Energy providers give you more control over your energy needs, from scalable plans to renewable energy. So, it's best to opt for a supplier that has good customer service. It's also advisable to choose a provider whose customer service is available by phone, not just by email.

Tips

How to save electricity?

When electrical appliances go into standby mode, they continue to consume electricity. Turn off unused equipment. Set electronic devices to turn off automatically after a set period of time. Turn outlet switches to Off when they are no longer needed.

The energy classification of electrical appliances

Use multifunctional appliances to save electricity

Choose a supplier according to your habits

Be aware

that some suppliers offer special weekend rates on electricity. This way, you can cook at leisure on the weekend, or use your most energy-intensive appliances on this occasion.

The right reflexes to adopt

When

cooking, cover pots and pans to optimize cooking. Use LED or energy-saving light bulbs, to save electricity. Remember to check your home's insulation as winter approaches: by reducing heat loss, you'll make significant savings on your heating bill.
