They do not want to be tied into long-term agreements. They do not want exit fees. They want the freedom to switch energy suppliers if a better deal becomes available. That is where no contract energy tariffs — often called variable or rolling energy tariffs — come into consideration. In this in-depth guide, we will explain from first principles: what a no contract energy tariff actually is, how variable energy tariffs work, the advantages and disadvantages, how to compare no contract energy deals properly, and when flexible energy plans make financial sense. Our goal is to give you the clarity needed to compare energy tariffs with no contract confidently and strategically.
What Is an Energy Contract?
Before we compare energy tariffs with no contract, we must first define what an energy contract actually means. An energy contract is a legally binding agreement between you and an energy supplier. It sets out: the unit rate (price per kWh), the standing charge, the contract duration, exit fees (if applicable), and billing terms.
Fixed-Term Contract
A fixed-term energy contract locks in your rate for a set period — typically 12, 18, or 24 months. Leaving early often results in exit fees.
Example: 24-month fixed at 28p/kWh
No Contract (Rolling/Variable)
A no contract energy tariff does not lock you in for a fixed duration. You can switch energy supplier without paying exit penalties. This flexibility is the defining feature.
What Is a No Contract Energy Tariff?
A no contract energy tariff is usually a variable or standard variable tariff (SVT). It means: there is no fixed end date, there are typically no exit fees, and your unit rate can change. This is sometimes referred to as: rolling energy tariff, flexible energy plan, variable energy tariff, or standard variable tariff. While these terms are related, they are not always identical. The key characteristic is freedom to leave without penalty.
How Do Variable Energy Tariffs Work?
Unlike fixed tariffs, variable energy tariffs fluctuate. Prices may change due to: wholesale energy market conditions, regulatory price caps, or supplier pricing adjustments. This means your monthly energy bill can rise or fall depending on market conditions.
The difference is that the unit rate may not stay constant.

Advantages & Disadvantages
✅ Advantages

⚠️ Disadvantages
- Price Volatility — rates may increase with little notice
- Budget Uncertainty — unpredictable bills create financial strain
- Often Higher Long-Term Costs — SVTs frequently more expensive
At Utility King, we often see customers remaining on rolling tariffs by default — not by strategic choice. That can lead to unnecessary overspending.
Who Should Consider No Contract Tariffs?
✅ May Be Suitable For:
- Short-term renters
- Homeowners planning to move
- Customers waiting for market stabilisation

- High-usage households during volatile markets
How to Compare No Contract Tariffs
Unit Rate
Compare to fixed tariff options.
Standing Charge
High charges can significantly increase annual cost.
Regulatory Protection
Is the tariff subject to an energy price cap?
Historical Price Trends
Has the supplier frequently increased rates?
Estimated Annual Cost
Calculate based on actual usage.
The cheapest energy tariff with no contract is determined by total annual cost — not marketing claims.
Is Switching to No Contract Energy Supplier Safe?
Yes. Switching energy suppliers does not interrupt supply, does not require infrastructure changes, is regulated by national energy authorities, and includes consumer protections. The electricity and gas grid remains the same regardless of supplier. Safety concerns should focus on financial suitability, not physical supply risk.
Fixed vs No Contract Comparison
| Factor | Fixed Tariff | No Contract Tariff |
|---|---|---|
| Rate Stability | High | Low |
| Exit Fees | Often Yes | Usually No |
| Budget Predictability | Strong | Moderate to Low |
| Flexibility | Limited | High |
Utility King's Perspective
Comparing energy tariffs with no contract is about understanding trade-offs. Flexibility can be valuable — but it should not come at the expense of long-term affordability.
If you are actively monitoring the market and willing to switch when needed, a no contract energy deal can be strategic. If you prefer peace of mind and stable monthly costs, a competitive fixed tariff may offer better value. Energy comparison is not about avoiding commitment. It is about making informed, financially aligned decisions.
