Fixed price energy tariffs: Is fixed rate energy right for you?

By OVO Energy Saturday 07 November 2020

Fixed rate energy tariffs (also known as fixed price plans) are a popular choice nowadays, as they offer customers a safeguard against rising energy prices.

What is a fixed-rate or a fixed-price tariff?

There are two types of energy tariff – a fixed energy tariff (also known as a fixed-price or fixed-rate plan) and a variable energy tariff

A fixed-rate tariff sets what you pay per kWh. By the way, a kilowatt hour (kWh) is the unit used to measure energy, just like how kgs measures weight. This is locked at the same price until the end of your contract. Basically, it doesn‘t go up or down if the wholesale energy market (where suppliers buy their energy from) fluctuates. 

Fixed-rate deals usually last between 12 and 24 months. During this time, your rate per kWh remains the same. Of course, this doesn’t mean your bill remains the same. You still pay for the amount of energy you use. You are only fixing the price per kWh. The more energy you use, the more you’ll pay – same as ever. 

The other type of energy tariff is a variable rate. In a variable rate plan, what you pay per kWh isn’t fixed – your rate is at the discretion of your energy supplier and could change at any time, depending on the market. As the wholesale energy rates rise, so could your rate. On the other hand, if the prices fall, you may end up paying less (but falling wholesale prices don’t always result in lower bills).

Find out more about all the different types of tariff on the market in our explanatory guide. 

Why might wholesale energy prices go up or down?

Wholesale gas and electricity prices can fluctuate daily, much like the stock market. Prices depend on a range of factors, including world events and supply-and-demand.. Variable rates don’t change quite so frequently – suppliers will warn their customers if they can expect a rise or a drop in prices. At OVO we give our members 30 days warning.

Pros and cons of a fixed-rate tariff

The advantages of a fixed-rate tariff

  • Cheaper energy – healthy competition between energy suppliers has pushed the prices of fixed rate tariffs down. This means they’re often cheaper than the variable tariff rates.

  • Security – a fixed-rate keeps you protected against energy price rises.

  • Budgeting – the regularity of a fixed-rate gives you peace of mind. It’s also easier to work out your energy costs. 

The disadvantages of a fixed-rate tariff

  • Expensive energy – if wholesale energy prices fall, you could end up paying more than with a variable tariff

  • Locked in – fixed-rates are on a fixed contract, meaning you can’t change your mind without incurring a cost

  • Cancellation fees – if you do want to cancel your contract, you may be charged an exit fee on both fuels

Why you need to know when your fixed-price tariff ends

Your fixed-rate tariff contract is set for a fixed term – probably 12 to 24 months. It’s important to make a note of the date it finishes. Your supplier will remind you in advance, but it’s good to be prepared. On this date your rate will be rolled on to your supplier’s default tariff, which will probably be a standard variable rate. It’s likely that this will be more expensive than the fixed-rate you were on.

And remember, variable rates can go up with the price of wholesale energy. So, if you keep your end-date in mind, you give yourself many more options. 

What to do when your fixed-price plan ends

Before your fixed-price energy tariff contract comes to an end, find out which tariff your supplier will be moving you to. They are obliged to to send out end-of-contract letters, and they may offer you another fixed-rate tariff. But before you accept, consider your options.

  • Compare all available energy plans online. You may find the best fixed energy tariff is with another supplier

  • If you find a cheaper deal with another gas and electricity supplier, now’s the time to switch 

TOP TIP! You don’t have to wait until the day your fixed contract ends. You can change your energy plan up to 49 days before. This is why it’s super-important to be in the know. You could be saving money over a month and a half before the end of your contract!

Frequently asked questions

Does a fixed-rate tariff mean my monthly bills will remain the same throughout my contract?

Unfortunately not. A fixed-rate only refers to the amount you pay per kWh. You still need to pay for how much energy you use. When you use more energy, you pay more. When you use less energy, you pay less. Same as always. 

This also applies for monthly Direct Debits (DD). Your supplier estimates your DD payment by calculating how much energy they think you’ll use over the year. If you use more, they’ll request your DD payment goes up. If you’re using less, your DD payment could go down. 

Are fixed-rate tariffs cheaper than variable?

Generally speaking, if you shop around, you’ll find that the best fixed-rate tariff will be better value than a variable rate one.

Are there any hidden charges or cancellation fees when switching?

If you’re on a variable rate tariff, you can switch at any time, without incurring any cost. If you’re on a fixed-rate tariff, most suppliers charge exit fees if you want to get out of the contact before the term is complete.

These exit fees must be paid for each fuel. So if your supplier charges £30 as an exit fee, and you’re switching both gas and electricity, you’ll pay £60. And remember, these fees cannot be charged within 49 days of your contract’s end date. 

What’s the cheapest energy tariff on the market?

The cheapest tariffs vary all the time, depending on the supplier. And they depend on where you live too. Do your research and don't forget to check directly with suppliers for their best deals. 

The cheapest tariff on the market will usually be a fixed-rate, fixed-term dual fuel (gas and electricity) deal, paid monthly by Direct Debit.

I’m on a fixed-rate tariff and I’m moving home. Will my energy supplier let me keep my fixed-rate?

Most suppliers will let you transfer your fixed-rate contract to your new home. If you’re moving to a different area, the rates may be slightly different, but you should get a comparable saving. 

If you’re planning to fix your energy rates, but know you’ll be moving soon, check with your energy supplier to make sure you can take the same deal with you.

If I switch supplier, will my energy service be interrupted?

Switching is easy. Once you’ve chosen your new energy supplier, they’ll do everything for you, with no interruption to your service. The switch usually takes 21 days, so make sure you switch before the end of your contract, for the best possible rates. You don’t even have to inform your old supplier that you’re leaving. Phew!
