Although the Energy Price Cap was lowered to £1,720 on 1st July 2025, many fixed tariffs are now undercutting it by over £200 a year, with deals available from just £1,479.
With the next cap announcement due on 27 August and forecasts predicting a 1.5% increase from 1 October 2025, fixing your energy rate now could help you avoid higher bills and bring greater certainty ahead of the colder months.
Here is a list of the top fixed-rate energy tariffs available, 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.
