With energy costs being a significant concern for students wanting to study and live in the UK, finding the most affordable gas and electric suppliers is crucial. Fortunately, the UK energy market is competitive, allowing consumers to choose from a range of providers. 

In this guide, we will explore some of the cheapest gas and electric suppliers in the UK, providing you with valuable information to help you make an informed decision and potentially save money on your energy bills.

General Living Costs in the UK

The average cost of living in the UK varies depending on various factors, such as location, lifestyle choices, and individual circumstances. Generally, living in the UK can be quite expensive compared to other countries. The largest expenses for most students are student accommodation, transportation, and food. 

Renting a one-bedroom apartment in a city centre can cost anywhere between £800 and £1,500 per month, while outside the city, it can range from £600 to £1,000. Utility bills, including electricity, heating, water, and internet, can add up to around £150 to £200 per month. 

Transportation costs, including public transport or owning a car, can vary, but a monthly travel pass in a major city typically costs around £100 to £150. Groceries and dining out can also be significant expenses, with a monthly food budget ranging from £200 to £400 depending on personal preferences. Other expenses, such as healthcare, insurance, and entertainment, should also be taken into account when considering the overall cost of living in the UK. 

Note that there are some ways to reduce cost of living in the UK, including choosing the right energy supplier. 

Understanding the UK Energy Market

Before diving into the cheapest suppliers, it's important to understand the structure of the UK energy market. The market is divided into two segments: the wholesale market and the retail market. Wholesale energy prices fluctuate based on factors like supply and demand, global events, and weather conditions. Retail suppliers purchase energy in bulk from the wholesale market and sell it to consumers, setting their own prices and tariffs.

Energy Price Rises

Energy prices in the UK have been experiencing a significant increase. There are several factors contributing to this rise. Firstly, the reliance on natural gas as the primary source of electricity generation in the country has played a role. Natural gas prices have been on the rise globally, and since it is a major component in energy production, its cost directly impacts electricity prices.

Furthermore, the UK has been transitioning towards renewable energy sources like wind and solar power. While this shift is positive for environmental reasons, the initial investments and infrastructure development required for renewable energy generation have added to the overall energy costs.

Why Switch Gas and Electric Suppliers in the UK

There are several reasons why individuals in the UK might consider switching gas and energy suppliers. Some key factors include:

1. Cost savings

One of the primary motivations for switching suppliers is to save money on energy bills. Different suppliers offer varying rates and tariffs, and by comparing options, consumers can find better deals and potentially reduce their energy costs.

2. Fixed-Rate Tariffs

Some suppliers offer fixed-rate tariffs, where the price per unit of energy remains consistent for a specific period, typically 1–3 years. This can provide stability and protection against price increases in the volatile energy market.

3. Green Energy Options

Many consumers are increasingly concerned about the environmental impact of their energy consumption. Individuals can support a cleaner and more sustainable energy sector by switching to suppliers that offer renewable or green energy options.

4. Improved Contract Terms

Switching suppliers provides an opportunity to review and select contracts that align with specific preferences and requirements. This includes considering factors such as contract length, payment options, and billing frequency.

How to Choose the Best Energy Suppliers

Choosing the best energy supplier involves considering various factors to ensure that the supplier meets your specific needs and preferences. Here are some key steps to help you make an informed decision:

1. Research and Compare Suppliers

Start by researching and comparing different energy suppliers in your area. Look for reputable companies with a track record of reliable service and positive customer reviews. Consider factors such as pricing, customer satisfaction ratings, renewable energy options, and additional services they offer.

2. Determine Your Priorities

Identify your priorities and preferences. Are you primarily focused on finding the lowest price or prioritising renewable energy options? Consider factors such as customer service, billing methods, online account management, and any specific requirements you may have.

3. Compare Tariffs and Pricing

Energy suppliers offer various tariffs and pricing structures. Compare the unit cost per kWh, standing charges, and any additional fees or discounts associated with different tariffs. Look for transparent and competitive pricing that suits your energy consumption patterns and budget.

4. Consider Contract Terms

Review the contract terms offered by each supplier. Pay attention to the contract length, exit fees, and any terms and conditions that may impact your flexibility as a customer. Ensure that the supplier's contract terms align with your preferences and requirements.

5. Check Customer Service and Support

Reliable customer service is crucial when dealing with energy suppliers. Research customer reviews and ratings to assess the level of customer satisfaction with a particular supplier. Consider factors such as ease of communication, responsiveness to queries or complaints, and support channels offered (phone, email, online chat, etc.).

Switching Energy Suppliers’ Process

Switching energy suppliers in the UK is a relatively straightforward process. Here's a step-by-step guide to help you understand the general process:

1. Choose A New Supplier

Once you have identified a suitable supplier, initiate the switching process by contacting them directly or visiting their website. Most suppliers have online forms or dedicated phone lines to assist with the switching process.

2. Provide Information

You will need to provide certain information to the new supplier to facilitate the switch. This may include your current energy supply details, metre readings, personal information, and your current supplier's name and account number.

3. Review the New Contract

The new supplier will provide you with a contract or agreement outlining the terms and conditions of your new energy supply. Read the contract carefully, paying attention to pricing, contract length, exit fees, and any special terms or conditions.

4. Cooling-Off Period

After you sign the contract, you typically have a 14-day cooling-off period during which you can change your mind and cancel the switch without any penalties.

5. Inform Your Current Supplier

Your new supplier will handle most of the switching process on your behalf, including notifying your current supplier of the switch. However, it's a good idea to inform your current supplier about your intention to switch to avoid any confusion.

6. Metre Readings

On the day of the switch, take metre readings for both your gas and electricity metres. This ensures accurate billing and prevents any disputes later on. Provide the metre readings to both your old and new suppliers.

7. Final Bill and Account Closure

After the switch, your previous supplier will issue a final bill based on the metre readings you provided. Pay any outstanding amount and ensure a smooth account closure.

It's important to note that the time it takes to complete the switch can vary, but it usually takes around 21 days from the initiation of the switch. During this period, your energy supply should not be interrupted, and both your old and new suppliers will keep you informed about the progress of the switch.

And there you have it!

Finding the cheapest gas and electric suppliers in the UK involves researching and comparing various options. Remember, it's not only about finding the cheapest supplier but also considering your specific energy needs, customer service quality, and any additional benefits or rewards programmes offered. 

Always keep an eye on the energy market, as prices and deals change regularly. By staying informed and proactive, you can make the most cost-effective choices for your gas and electric supplies.
