Energy supplier performance results


How to use this chart to help you choose an energy supplier

The most important piece of information is in the column marked “Complaints reported to consumer bodies per 100,000 customers” . Select a few of the suppliers with a low complaints ratio, then go to an OFGEM Accredited Comparison site to see which one of these suppliers is offering the cheapest online tariff.

Choose a supplier which has:

  • Fewer complaints
  • Been established for a reasonable period
  • Fully recorded figures
  • Offers a cheap online tariff

Some newer suppliers may not be listed yet as there is not enough information to record their performance

If you click the top right hand column, you can sort the order of the scores

Update 4th February 2018 18:35

This chart is currently being updated. Some figures are missing due to some of the suppliers being very new, where information is just not available yet or, some of them have not complied with the OFGEM rules to provide this information.

Complaints recorded by supplier per 100,000 customers

Most of the complaints in this column are not serious complaints. Some of the suppliers probably even record the fact they have a customers name with the wrong spelling. It’s a good sign when you see complaints in this column, it means the supplier is not trying to hide anything.

This column should have more complaints registered than the next column!

Complaints reported to consumer bodies per 100,000 customers

This is the important column. These are complaints the supplier has not given the customer an acceptable resolve for, so the customer has sought third party intervention.

This column should have less complaints registered than the previous column!

Play it safe

We have awarded points out of 100 to help you with your choice of supplier. A good rule of thumb would be to select a supplier which has 70 or more points.

You can see how we have awarded the points here

Some of my thoughts whilst putting this together

I really wanted to award more points to OVO Energy, but they have let themselves down by not being upfront with customer complaints reported to them. They couldn’t have possibly recorded all of their complaints. It’s just not possible to have 79 complaints per 100,000 customers and, have 90.3 complaints reported to third parties.

Also, I may be being a bit unfair to Places for People Energy. They are showing the least complaints at 19 per 100,000 customers. But I believe this to be the case because they haven’t accumulated a lot of customers yet.

Some of the newer suppliers have not recorded their complaints yet, but they should have done so. This is part of the OFGEM licence conditions.

I’m not sure what’s going on with Scottish Power. As one of the Big 6 original suppliers, they shouldn’t be going down this slippery slope.

British Gas customers really need to get to grips with what’s going on. There’s nothing wrong with their service. As the biggest supplier (They inherited all the customers at the start of privatisation), they are managing to hold onto the customers who are reluctant to switch their supplier. They are the ones paying the most with their Standard Energy Tariffs. British Gas can also capture the customers at the other end of the market. That’s the ones who like to shop around online for a cheaper energy deal. They have this end covered through the Sainsbury’s Energy brand.

Ofgem Accredited Comparison Sites

If you are going to switch to a cheaper online energy deal, then use one of the Ofgem Accredited sites. They are governed by a strict set of rules which put the consumers needs first!

    I was interested to see your comment about Ovo. I am looking to change from EDF, but have a 30 year old dial meter (we cannot upgrade to smart meter even if we wanted too – too many problems with current generation, and there’s no signal here so it wouldn’t work). I was concerned with the complaints I’ve found on the web about Ovo charging for meter replacement. The Electricity Act 1989 (amended) restricts charges for replacement of a faulty meter when it is marked as belonging to the supplier. I questioned them about this via their web page contact form and got no reply. That is not a good sign, particularly as theirs is one of the highest standing charges which is supposed to cover things like meters. Very disappointing given their rating on other issues.

      You make an interesting point, Steve. If you contact an energy supplier asking them to change your meter, they will charge you for it. Unless of course, you are requesting a new smart meter, where no charge should be made to yourself. However, as you are stating you don’t receive a mobile signal where you are, then a smart meter is of no use to you.
      Another point to note: If you contact your supplier, suggesting there is a fault with your meter, they will charge you for running a test on it. If they find a fault after testing, they will replace the meter and, refund any charges made. If they don’t find a fault, they will most likely leave the meter in place.

    HI, we are thinking of transferring to Together Energy which is the cheapest provider from one of the OFGEM accredited price comparison sites. However, apart from TrustPilot who have given them a high customer satisfaction rating we cannot find any other feedback. I have trawled the OFGEM website but there is no mention of them in any of their customer satisfaction surveys and they are not mentioned in the table above which lists 29 suppliers. Have you any thoughts please?

      Hi Lesley. Many thanks for your comment. Together Energy are a new supplier.They were not active when the table was put together. It’s very difficult to get the measure of a new supplier until they have been in business long enough to have some sort of track record. I understand it is tempting to switch to a supplier showing the cheapest price.However, sometimes it can be more bother than it’s worth. I’m not saying this supplier will provide a bad service, but at this early stage, I would go with a supplier with more of a track record!

    Very useful website but having scrolled down the list of suppliers the great majority of those you recommend, i.e. those over 70, are the major players and certainly the most expensive. I switched last year to Flow Energy as being the cheapest and have had no complaints and I note they have a score of 75. After all these companies don’t control the distribution of the gas or electricity they just charge you for it. the larger the number of suppliers the best chance we, the consumer, have of forcing prices down, or at least keeping them near to inflation levels. Flow Energy, relatively new to the market, have now increased their prices by around 10% and will be considered but are still a little dearer than British Gas and a whopping £15 a month dearer than Utility Point, a new player in the market place. What really is the danger of signing up to a company like Utility Point?

      Thanks for your comment, Brian. It’s quite difficult to give an accurate measure of the newer suppliers at the moment because there just isn’t enough information on them yet.
      Utility Point, are one of the suppliers we don’t have any measure on at all because they are so new. On a personal level, I wouldn’t switch to a new supplier because I prefer to be sure of having little or no problems. If you’re a person who doesn’t care about any kind of service or getting everything right, and, I’m not suggesting this company will get it wrong, then, go ahead and give them a go. As long as they don’t go the same route as some of the other new suppliers, you could be okay with them.

    If I switch to a company who, as part of the agreement, they fit a smart meter and then a year or so later I decided to switch away from this company – what happens with regard to the ownership/use of the smart meter and would the new energy supplier accept the meter if it was left by the previous company?

      Hello Maurine. Ownership of the meter is not important as you still pay for it through your standing charge irrespective of who your energy supplier is. If you switch supplier after you have had a smart meter installed, your new supplier will continue to use the same meter to determine your energy usage. Many of the new suppliers don’t have the facility to to record smart meter readings remotely. Therefore, they will just take the reading manually and, bill you for the energy consumed in the normal way.

      Utility Point is a new supplier. All suppliers must be licenced by OFGEM. Accreditation only applies to comparison sites.
