As we start the summer months, UK energy consumers are seeing energy prices fall by around 7% under Ofgem's (the energy regulator) 'Energy Price Cap', which controls the maximum cost suppliers can charge for gas and electricity on their 'Standard Variable' tariffs. This next change, due to take effect from 1st July 2025, will see the average UK energy bill fall from £1,849 to £1,719 - a saving of £130. However, for those savvy enough to shop around, greater savings are available by opting for a "fixed" rate energy tariff. By doing so, customers can save well over £300 a year and reduce their energy bills by 16% compared to current prices.
By switching to a fixed-rate energy tariff, households can lock in greater energy savings while shielding themselves from volatile market conditions and gaining control over a significant portion of their monthly expenses.
Here is a list of the top 10 fixed-rate energy tariffs available, ranging from one to two-year deals, which offer stability against the unpredictable energy market:
| Supplier | Tariff Name | Estimated Annual Bill |
|---|
NOTE: The prices above are based on an average UK energy consumption of 2,700kwh Elec and 11,500kwh Gas per year. In the industry these are referred to as Typical Domestic Consumption Values (TDCVs).
Advantages of this type of tariff are:
Disadvantages are:
This type of tariff benefits from the unit price being set at a certain rate for the life of the tariff. It is important to note that this does not mean your energy bill will remain the same - if you use more energy, your bill will be more. If you use less energy your bill will be less - it is the price you pay per unit of energy that is fixed.
With this type of plan you know exactly what your energy will cost you for the life of the tariff, if you keep an eye on your consumption. These energy tariffs can be fixed for any length of time, for example 12 months, or 5 years. You will normally find that the longer the tariff is fixed for, the more expensive it will be as suppliers allow for the fact that there is more likely to be a price rise if you are on the tariff for a longer period.
No! With a fixed rate, whether market prices go up or down, yours will remain the same. With a capped rate, prices will change in line with the market, but will not go over a set limit. So if market prices go down, your rate will go down, but if market prices go up, your rate will not rise above the cap. Capped price tariffs can be a little more expensive than fixed rate but you will benefit from the flexibility.
