    Looking for a good price is probably priority number one, but there are other areas to consider when choosing a new energy supplier:
  • What type of plan is it and is the tariff fixed?
  • How long does the contract last and is there an exit fee?
  • How will payment be taken?
  • If something goes wrong, does the supplier offer good customer service?
    In addition, it’s important to consider your current circumstances and preferences:
  • What is the energy efficiency in your household like?
  • Is it important that your supplier offers green energy?
  • Would you prefer for both gas and electricity to come from the same supplier?
    Other reasons to switch:
  • You’ve just moved to a new home
  • It’s suspected that prices are about to rise so you want a fixed tariff
  • A financial change meaning you need to review your outgoings
  • Your current deal is coming to an end

The UK’s “Big Six” energy suppliers

Six energy companies have traditionally dominated the industry, and many are household names in the UK.

We call these the Big Six:

  1. British Gas
  2. EDF Energy
  3. E.ON
  4. nPower
  5. Scottish Power
  6. SSE

Almost 80% of homes in the UK are supplied gas or electricity by the Big Six, and this group of energy suppliers includes some of them are the oldest names in the industry.

The longest running business in the Big Six is British Gas, which opened its doors 200 years ago and now serves more than 5 million customers.

With an enormous market share, reliable reputations and, for some, centuries of experience, the Big Six often looks like an appealing choice for your energy supplier.

However, you might find that the Big Six don’t offer you the cheapest options when compare energy prices using our online tool. If that’s the case, consider going with a smaller supplier.

Smaller energy suppliers

Don’t be taken with the Big Six just for the sake of it, size isn’t everything. Smaller, independent energy companies are thriving in the UK’s domestic energy market, and one of these companies could offer you the best deal for your household.

Small suppliers challenging the reign of the Big Six include:

Switching to a smaller supplier

Wondering whether it is safe to switch to a smaller supplier? Regulations from Ofgem apply to all of the UK’s energy suppliers, big or small, so you can be safe in the knowledge that smaller suppliers follow all the same rules as the Big Six.

On top of this, many small suppliers can offer cheaper deals with better customer service, making them serious contenders in the gas and electricity market.

Big Six Other Suppliers Price Difference
Average Standard Variable Rate (SVT) £1,253.94 £1,148.88 £105.06
Cheapest available tariff £932.24 £872.57 £59.67

However, whereas the Big Six have committed to the Energy Switch Guarantee, which promises a speedy and safe switch from one energy provider to another, not all smaller suppliers have done so.

In addition, there have been some well-known instances of small suppliers going bankrupt, possibly due to charging extremely low energy prices. If you find yourself with a supplier who goes bankrupt, don’t panic, you won’t be left without power. Ofgem will move you to a new supplier, and then you can look at your options, compare and switch energy suppliers if you prefer.

Shop around to avoid SVTs

When you use our online comparison tool to view the best energy quotes available, you might notice that some of the cheapest deals come from fixed-rate tariffs.

Fixed rate tariffs provide a locked-in rate for a designated period of time, which usually lasts about a year, depending on your contract. This means that, whilst your bills may rise or fall in line with your energy usage, the cost of each unit of gas or electricity will remain constant despite changes to the energy market.

Whilst fixed rate plans can protect households from energy prices, you should shop around for another deal when your contract is up. Otherwise, you might be moved to a standard variable rate tariff (SVT) that costs you more money long-term.

You will be notified by your energy supplier when your contract approaches the end. When they get in touch, start comparing energy bills using Utility Saving Expert to find a better quote.

Once you find a better deal, you can switch within the last 49 days of your existing contract without paying an exit fee. That means you don’t need to wait for your existing contract to end before you switch!

Energy supplier trivia: Priced by postcodes

Did you know that where you live can impact your energy bills? The location of your home can affect energy prices based on some factors you may not have considered. For example, some regions have denser populations, and that makes servicing those customers easier for energy suppliers, so they can offer cheaper rates.

Whilst living costs in London are usually the highest, it is a relatively cheap location for heating, whereas the South West of the UK tends to have the most expensive winter heating costs.
