These tariffs are directly influenced by the energy price cap set by Ofgem, the UK's energy regulator, meaning their rates can change every three months. Understanding how an SVT works is crucial for managing your household budget amidst fluctuating energy costs. Understanding your SVT is key to managing your energy costs.

It's designed to be flexible, but this flexibility comes with rates that can change, unlike fixed-rate tariffs which lock in prices for a set period. ### Key characteristics of an SVT SVTs are distinct from fixed tariffs in several ways. They do not have a fixed end date, offering continuous supply without the need to renew a contract. Crucially, SVTs typically do not incur exit fees if you decide to switch to a different tariff or supplier, providing freedom to move at any time. However, the unit rates you pay for electricity and gas, along with the daily standing charge, can vary. ## The Ofgem energy price cap and your SVT ### How the price cap works Ofgem, the UK's energy regulator, sets the energy price cap to limit the maximum unit rate and standing charge that suppliers can apply to SVTs. This cap protects households from excessive charges, ensuring that default tariffs remain fair. ### Quarterly rate adjustments The Ofgem energy price cap is reviewed and updated quarterly, with changes taking effect on 1 January, 1 April, 1 July, and 1 October each year. This means that the cost of your energy on an SVT can change every three months. For example, under the Ofgem Price Cap from 1 July to 30 September 2026, the typical electricity unit rate is 26.11p per kWh with a 57.19p daily standing charge, and the typical gas unit rate is 7.33p per kWh with a 29.04p daily standing charge. ### Price cap versus total bill It's important to remember that the energy price cap is a limit on the unit rates and standing charges your supplier can charge, not a cap on your total energy bill. Your overall bill will still depend on how much energy you use. The average UK home uses around 2,500 kWh of electricity and 9,500 kWh of gas per year. ## Pros and cons of a Standard Variable Tariff ### Advantages of an SVT The primary advantage of an SVT is its flexibility. Without a fixed contract end date or exit fees, you can switch tariffs or suppliers whenever you find a better deal without penalty. This can be beneficial if you anticipate market prices falling, allowing you to benefit from lower rates sooner. ### Disadvantages and risks The main drawback of an SVT is the unpredictability of costs. Since rates can change quarterly in line with the Ofgem Price Cap, your energy bills can fluctuate, making budgeting more challenging. While the cap offers protection, it doesn't prevent prices from rising. Staying on an SVT out of inertia might mean missing out on potentially more stable or cheaper fixed deals available in the market. ## Understanding your current tariff and alternatives ### How to check your tariff To understand your energy costs, check your latest energy bill. It will clearly state your current tariff name, unit rates, and standing charges. Many suppliers, including Fuse Energy, also provide this information transparently within their online accounts or mobile apps. ### Fixed versus variable tariffs: which is right for you? When considering your energy plan, the choice often comes down to fixed versus variable tariffs. Fixed tariffs offer price certainty, locking in your unit rates and standing charges for a set period, usually between 12 and 18 months. This can provide peace of mind and make budgeting easier. However, fixed tariffs typically come with exit fees if you leave early. Variable tariffs, like SVTs, offer flexibility with no exit fees but expose you to quarterly price changes. Your decision should align with your comfort level regarding price fluctuations and your need for budget predictability. ### Making an informed decision Consider your household's energy usage habits and how important budget predictability is to you. If you prefer stable, predictable bills and are willing to commit to a contract, a fixed-rate tariff might be more suitable. If you value the flexibility to switch at any time and are comfortable with potential price changes, an SVT could work, provided you actively monitor market conditions. ## Taking control of your energy costs ### Comparing Fuse Energy tariffs Fuse Energy aims to empower householders by offering transparent tariff options, including both variable and fixed rates.
