What Is a Standard Variable Tariff (SVT)?

An SVT is the default tariff you’re placed on if you don’t actively choose a deal. Rates can go up or down with the market, offering flexibility but little price certainty.

Pros:

  • No exit fees, switch at any time
  • Flexibility to move to a better deal if prices drop

Cons:

  • Rates can increase with little notice
  • Often more expensive than fixed tariffs

What Is a Fixed Tariff?

A fixed tariff locks in your unit rates for a set period, usually 1-3 years. This provides budget certainty and protects against price rises.

Pros:

  • Predictable bills for easier budgeting
  • Protection from market volatility

Cons:

  • You won’t benefit if market prices fall
  • Early exit fees may apply if you switch before the contract ends

SVT vs Fixed: Which Is Right for Your Business?

  • Fixed tariffs are ideal for businesses wanting predictable costs and protection from market volatility.
  • SVTs suit those who value flexibility and are willing to monitor the market for better deals.

Most businesses benefit from the stability of a fixed tariff, especially in uncertain markets. However, it’s important to review your contract end dates and compare offers regularly to avoid being rolled onto an expensive SVT.
