Find out more about standard variable tariffs (SVTs), and why you don’t want to be on one of these energy tariffs for too long.
An SVT (sometimes called a standard energy tariff) is an energy supplier’s default tariff.
SVTs are usually the most expensive gas and electricity tariffs, because suppliers can change the unit rate prices at any time alongside wholesale energy prices.
You’ll often find yourself on one of these tariffs when a fixed tariff plan ends and you don’t switch to another, or if you’ve never switched suppliers before.
SVTs do just what their name suggests – they vary the price you pay for energy.
But they don’t go up and down randomly; they reflect wholesale energy prices. So if wholesale prices go up or down, your SVT may do the same. Depending on your supplier this may not always happen, and probably not immediately. Suppliers can be slow to pass on falls in wholesale prices to SVT customers.
Even if wholesale energy prices do drop, they usually only account for less than half your energy bill. You’ll still have to pay for the costs of delivering energy, meeting government environmental initiatives, taxes and operating costs. Not to mention your supplier’s profits.
That means even if you’re on an SVT, and you’ve heard energy prices are falling, you may not see a cut in your energy bill. Even if you do, it’s likely you’ll save more by shopping around and switching to another tariff.
If you shop around and look for the best energy deal, it’s unlikely to be an SVT. That being said, if you do find one you’re keen on, these are the advantages and disadvantages to consider.
You’re not contractually bound to an SVT, so there’s no end date. Your rate simply goes up, down or stays the same according to the market and price increases decided by your supplier.
If you’ve never switched energy suppliers, you’re probably on your supplier’s SVT. This can also happen if your fixed tariff plan has expired, and you haven’t switched to a new plan.
Some suppliers are moving customers onto so-called “temporary tariffs”. These are very similar to SVTs, with the exception that the rate is locked in for a year.
Check your bill, or ring your supplier, to find out if you’re on an SVT. Different suppliers call their SVTs different names, so it’s worth double checking.
