Why Switch Gas & Energy Suppliers

Looking for the best energy supplier to save money on your energy bills? With high gas and electricity prices and poor customer service being among the most common reasons people switch energy suppliers, it’s essential to know what to look for when shopping around.

One of the most common reasons people switch is because energy prices are too expensive. This can happen if your energy supplier raises its prices, your contract is finished, you’re using more gas and electricity, or you initially underestimated how much energy you would use. If you’re looking to save money, keep an eye on prices and compare deals to ensure you’re getting the best deal possible.

If you’re looking for the best energy suppliers 2023, it’s essential to consider more than just the price.

Whatever your reason for switching, it’s important to compare your options carefully and read reviews from other customers to make sure you’re making the right choice.

In summary, if you’re looking to switch energy suppliers for cheapest gas and electric 2023, compare deals and consider more than just the price. With the right research, you can find the best energy supplier to save you money on your energy bills.

How To Choose Best Energy Supplier

Let us see some of the main reasons you should consider while choosing the best energy suppliers UK. 


Green energy

If you’re considering switching to a new energy supplier and want to make a positive impact on the environment, then a green energy deal may be the way to go. Green energy is generated through renewable sources like solar, wind, and renewable biogas.

Currently, around 40% of Ireland’s electricity comes from renewable resources, and this figure is set to increase in the future. With our green energy comparison service, you can easily explore the variety of green energy plans available and find the one that’s right for you. So why not take the first step towards a greener future today?


Customer service

It’s always wise to do your research before committing to a new energy supplier, and that includes checking out their customer service track record. You want to ensure you’ll receive the help you need if something goes wrong.

Fortunately, there’s an easy way to evaluate the quality of an energy company’s customer service: the Commission for Regulation of Utilities (CRU) website. Every year, the CRU publishes statistics on the buy steroids uk number of complaints received by each supplier, which are detailed in their Customer Care Team Annual Report for public viewing. This information can be a valuable resource in making an informed decision when choosing a new energy supplier.


Single or dual fuel

It’s important to consider whether a potential energy supplier offers both gas and electricity, known as a dual fuel deal, or if they only provide one or the other, known as single fuel. Although many energy suppliers offer both, some don’t, so it’s essential to double-check if you prefer to get all your energy from one provider. Opting for dual fuel has the added convenience of dealing with only one supplier, which is a significant factor for many households.

However, it’s worth noting that it’s also possible to switch your gas and electricity to two different suppliers and take advantage of two separate offers. So, it’s worth weighing up the pros and cons of each option to make the best decision for your household.


Online services

It’s important to take into consideration the online services offered by your potential energy supplier before making the switch. Online account access, digital bills, and a user-friendly mobile app are all helpful tools for managing your energy usage.

If you’re interested in a particular energy supplier’s mobile app, it’s a good idea to check out online reviews on platforms such as the Apple and Android app stores. This can give you a better idea of the app’s functionality and user experience, helping you make an informed decision.

If you have not switched your energy provider since your last contract ended, you might be paying more than what you should be paying for your gas and electricity.

How Much Can One Can Save By Switching Energy Suppliers

Switching energy suppliers can be an effective way for one to reduce their energy costs. By switching to a more cost-effective supplier, one can save up to 45% annually. However, the amount of savings that can be achieved may vary based on different factors, such as energy consumption, the contract’s length, and the type of energy used. In order to maximise savings, one should provide as much information as possible when comparing energy suppliers and consider working with a partner to help find the best deal.


Is Switching Provider A Complex Process?

The process of switching your energy supplier is relatively simple and comparable to switching your household energy supplier. However, it’s important to consider that the switch’s complexity may depend on your specific needs. But don’t worry, as your energy supply will not be affected during the transition. The transition process will be handled by your new and old suppliers, and won’t impact your energy supply.


Exit Fees, Contracts And Tariffs

If you’re considering switching energy suppliers, it’s important to be aware of any potential fees you may incur if you’re still under contract with your current provider. These fees, known as exit fees, can vary from supplier to supplier and could impact your savings in the short term. However, in the long run, you could still benefit financially from switching to a cheaper provider.

In addition, if your existing contract has ended, you may have been moved onto a more expensive tariff known as an “out of contract rate”. This could mean you’re paying more than you need to be for your energy. By shopping around and switching to a supplier with a more competitive tariff, you could save a significant amount of money on your energy bills. Keep in mind that many suppliers offer fixed-rate contracts for a set period of time, so it’s worth exploring these options when looking for a new supplier.

Charities and consumer advocate Martin Lewis are pushing for the implementation of a “social tariff” for energy to help low-income households struggling to pay their gas and electricity bills. This move could potentially save up to £1,500 for 12 million households. With the recent increase in household costs due to the energy crisis and the prepayment meter scandal, there is a growing demand for a revamp of gas and electricity billing. Energy suppliers have expressed their willingness to work on proposals for the social tariff. The government and Ofgem are currently exploring ways to fund and construct the social tariff.


How often do energy prices change?

Energy prices are constantly changing due to market supply, demand and wholesale costs. By choosing a fixed rate tariff, you can know your unit rates for a set period of time. The new Energy Price Guarantee will cap costs for typical households at £2,500 annually until June 2023, with a new cap announcement in May and changes effective from July 1, 2023.


What information do I need to switch energy supplier?

To provide you with an accurate quote, the supplier will require certain details from you. These include the name of your current energy supplier and tariff name, as well as the amount of energy you use in either kWh or pounds. You can easily obtain this information from a recent bill or your online energy account. If you are unable to locate the required details, they can still provide you with a quote based on estimated usage.


Getting cheap energy deals is not very difficult once you have a clear idea of what is it that you are looking for. With the energy prices rising, it is better to choose the cheapest electricity provider when you are starting as it will be better for you in the long run. Whether you are looking for green electricity, sustainable energy, or renewable energy there are only a handful of cheapest energy suppliers and you need to decide between the top four or five. Other ways of saving on energy bills are by going paperless, ensuring you are not paying for the previous tenant, choosing a dual fuel tariff, opting for fixed tariffs, etc. Saving energy costs is essential to maintain your expenses; hence choose your supplier wisely.



1. Who is the cheapest energy supplier in UK in 2023?

Square 1 is the cheapest SVT provider with only £151.50 pounds per month.


2. Is Octopus still the cheapest energy supplier?

With 100% green energy, you’ll pay a fair price for your energy. It might not be the lowest price available; rather, it’s about average. There is no way to quantify that.


3. Is it better to have a fixed or variable energy rate in 2023?

Fixed tariffs can be more expensive, and they sometimes have high exit costs and other binding terms. Variable tariffs provide you greater freedom, but you must regularly monitor energy rates and look for alternative offers if your supplier announces a rise in energy prices.


4. Is it worth getting a fixed energy tariff?

The energy market’s conditions ultimately determine fixed-rate tariffs; if wholesale prices are high, fixed deals will be less alluring. Generally speaking, though, a fixed-rate tariff will be more cost-effective than a variable-rate one if market conditions are favourable and you shop around.


5. Will my gas and electricity be interrupted if I switch?

Switching energy suppliers will not affect your gas and electricity supply. Your energy supply will continue as usual, and only the billing process will change to the new supplier.


6. Which is the cheapest energy supplier in London?

Outfox The Market, EDF Energy, Octopus Energy are some of the best and cheapest energy suppliers in London.


7. How long does it take to switch?

The Energy Switch Guarantee (ESG) ensures that suppliers complete a switch, including a 14-day cooling-off period, within 21 days. Your new provider should provide you with a transparent schedule of when the switch will occur, and there should be no interruption to your supply. By utilising our comparison service, selecting a new provider should only take a few minutes of your time.


8. What is a standing charge?

To cover the costs of supplying electricity and gas, including maintenance, to households, energy companies typically impose a standing charge. This fixed charge is either billed on a monthly or daily basis and is added to your usage costs, resulting in your total energy bill. To ensure transparency, your bill should itemize the standing charge, enabling you to understand the costs associated with your energy usage.


9. What is green energy?

Green energy, sourced from solar, wind, hydro, and wave power, has significantly lower carbon emissions compared to fossil fuels, making it an eco-friendly alternative. With the UK aiming for net zero carbon emissions by 2050, many energy companies now offer green tariffs, particularly for electricity. Although your energy supply will still come from the national grid, opting for a green tariff means your energy company will match some or all of the energy you use with renewable energy, thus increasing the overall percentage of green energy in the grid.
