What is a low-cost energy supplier?

A low-cost energy supplier is a gas or electricity provider that offers competitive tariffs, low standing charges, or both, helping you reduce your overall energy bills. These suppliers typically focus on keeping overheads low and passing savings on to customers through cheaper unit rates and simple online account management.

How can I find the cheapest energy supplier for my home?

To find the cheapest energy supplier for your home, compare unit rates (pence per kWh), standing charges, contract length, and any exit fees. Use an independent comparison or switching service, enter your current usage from recent bills, and review both fixed and variable tariffs. Always check the projected annual cost rather than relying on headline prices alone.

Will switching to a low-cost supplier affect my energy quality or reliability?

No. The gas and electricity you receive are delivered through the same national networks regardless of which supplier you choose. Switching to a low-cost supplier only changes who bills you and the price you pay, not the quality or reliability of the energy supply itself.

How much can I save by moving to a low-cost energy supplier?

Savings depend on your current tariff, usage, and region, but many households can save a significant amount each year by moving from a standard or default tariff to a competitive low-cost deal. The best way to estimate your saving is to compare your current annual cost with quotes from multiple low-cost suppliers based on your actual kWh usage.

Is it safe to switch to a smaller or lesser-known energy supplier?

Yes, as long as the supplier is fully licensed and regulated. Smaller or challenger brands must meet the same regulatory standards as the larger suppliers. If a supplier were to fail, your energy supply would continue and your account would be transferred to another licensed supplier under the regulator's safety net.

How long does it take to switch to a new low-cost energy supplier?

In most cases, switching to a new energy supplier takes around 5 working days once your application is confirmed, although this can vary by supplier. There is no interruption to your gas or electricity during the switch, and you do not need any new pipes, cables, or meters unless you choose to have a smart meter installed.

Do I need a smart meter to access the lowest energy tariffs?

You do not always need a smart meter to access low-cost tariffs, but some of the most competitive deals are designed for households with smart meters. A smart meter can help you track your usage in real time, avoid estimated bills, and access time-of-use or off-peak tariffs that may lower your overall costs.

Can I switch energy supplier if I am in debt or on a prepayment meter?

You can often switch supplier even if you are in debt or use a prepayment meter, but there are specific rules. If your debt is under a certain amount and has been owed for less than a year, you may still be able to move. Some low-cost suppliers also offer competitive tariffs specifically for prepayment or smart prepayment customers. Always check the supplier's terms before applying.

What should I check before choosing a low-cost energy supplier?

Before choosing a low-cost energy supplier, check the unit rate and standing charge, the length of the contract, any early exit fees, payment method options (such as direct debit), customer service ratings, and whether the tariff is fixed or variable. You may also want to review their green energy options and any rewards or referral schemes they offer.

Can I fix my tariff with a low-cost energy supplier?

Yes. Many low-cost energy suppliers offer fixed-rate tariffs that lock in your unit rate and standing charge for a set period, typically 12 to 24 months. Fixing your tariff can protect you from future price rises, but you should check any exit fees and compare the fixed price with current variable options before you commit.

What Affects the Cost of Your Energy?

UK energy prices are influenced by several factors. Understanding these helps you identify genuinely low cost offers:

Unit rate: Price per kWh for gas or electricity – the main driver of your bill.
Standing charge: Daily fixed cost just to be connected to the network.
Tariff type: Fixed deals provide price certainty; variable deals track market changes.
Payment method: Direct debit is often cheaper than paying on receipt of bill or prepayment.
Usage pattern: How much energy you use and when you use it, especially for Economy 7 or smart tariffs.

Types of Low Cost Energy Tariffs in the UK

Different households and businesses benefit from different tariff structures. We help you find the one that fits your needs.

Fixed Rate Tariffs

Lock in your unit rates for 12, 24 or 36 months. Ideal if you value bill stability and protection from potential price rises.

Variable Rate Tariffs

Prices can go up or down with the wholesale market. Flexible contracts are often fee-free to leave, giving you room to move when a cheaper deal appears.

Green & Renewable Deals

Choose low cost green energy tariffs backed by renewable generation. Cut your carbon footprint without overspending on your bills.

Business Energy Tariffs

Dedicated low cost business energy deals for SMEs and larger organisations, with tailored contract lengths and usage profiling.

Low Cost Does Not Mean Low Quality

A common myth is that a cheap energy supplier must deliver poor customer service or unreliable billing. In reality, many lean, technology-driven providers are able to offer competitive pricing while maintaining strong service levels.

All suppliers we work with are regulated by Ofgem, follow UK energy codes and are connected to the same national grid as the larger brands. Your gas and electricity are delivered through the same pipes and wires, regardless of who bills you.

Frequently Asked Questions About Low Cost Energy Suppliers

Are low cost energy suppliers safe and reliable?

Yes. All suppliers we work with are licensed and regulated by Ofgem. Your energy is delivered through the same national infrastructure and you have the same protections as with any major supplier.

Will my gas or electricity be interrupted when I switch?

No. The switch is an administrative change only. Your home or business stays connected at all times, and meter readings are used to ensure you only pay each supplier for the energy you have used.

How long does a switch usually take?

Most domestic switches complete within 5 working days, although timescales can vary slightly by supplier and tariff. We will provide an indicative go-live date during your quote.

Do I need a smart meter to access low cost tariffs?

Not always. Some advanced and time-of-use tariffs may require a smart meter, but many cheap fixed and variable tariffs are available with traditional meters as well. If a smart meter is required, your new supplier will arrange installation.

Can I switch if I am in debt with my current supplier?

In many cases you can still switch, especially if the debt is below a certain level or relates to a previous billing issue. Rules differ between prepayment and credit meters, so speak with our team for personalised guidance.

How often should I review my tariff?

We recommend reviewing your energy deal at least once a year, and always before your fixed contract ends. Energy Plus can monitor the market and help you move to a new low cost tariff when it makes sense.
