What happened to iSupply?

Who took over iSupply?

Below you can read our review of iSupply's energy before their closure. Information is provided for reference only.
iSupplyEnergy is a Bournemouth-based energy provider that was launched in 2012. While the company originally supplied solely electricity up until 2015, it now provides both gas and electricity to over 190,000 domestic customers across the UK.
In 2017, iSupplyEnergy was acquired by Vattenfall, a Swedish energy company that serves more than nine million customers across Europe. Vattenfall retained iSupplyEnergy’s employees and offices, and it continued to use the iSupplyEnergy brand name.
Having already invested more than £4 billion into renewable generation across the UK, Vattenfall focused on transitioning iSupplyEnergy into a more sustainable energy provider. iSupplyEnergy gained the resources to help its customers minimise their environmental impact at an affordable price.
In March 2020, EDF Energy acquired iSupplyEnergy from Vattenfall. EDF Energy already supplies gas and electricity to over five million domestic customers across the UK. Account transfers are set to begin taking place in April 2020. Most iSupplyEnergy customers can expect their accounts to be transferred by June.

You will likely have to make a complaint to your energy provider at some point in your lifetime. Let’s have a look at what you should do if you have to make a complaint to iSupplyEnergy, as well as a bit about what the provider’s complaints typically concern.
How do I make a complaint to iSupplyEnergy?
iSupplyEnergy lays out its complaints procedure on its website. The provider says it will do everything it can to provide a solution as soon as possible.
Customers looking to make a complaint should first call iSupplyEnergy’s customer service on 0330 202 0298 and explain to a representative what has happened. You can also send a message through your online account.
If you are not satisfied with how your complaint was initially handled, you can escalate it to the Customer Resolution Team at iSupplyEnergy. A member of the team will contact you within five working days.
To contact the Customer Resolution Team, you can either call 0330 202 0298, message the provider through your online account, or send an email to firstname.lastname@example.org. Customers can also write a letter addressed to Complaints, iSupplyEnergy Limited, Richmond House, Richmond Hill, Bournemouth, BH2 6EZ, or call customer service to arrange an appointment to meet with a representative.
If you are still not pleased with how your complaint was resolved, you can request an internal review. You can expect to hear back from a senior member of the Customer Resolution Team within five working days.
If a solution can not be reached, you can then request a deadlock letter from iSupply Energy. This is written confirmation that outlines the final position of the complaint. You can then refer the complaint to the Energy Ombudsman. You are still able to refer the complaint to the Energy Ombudsman without a deadlock letter as long as eight weeks have passed since you first made the complaint.
iSupplyEnergy customer complaints
According to the provider, billing made up for most of its customer complaints in 2019 at 40%, followed by payments at 19%. We took a look at customer reviews (article coming soon!) to see what previous and current customers of iSupplyEnergy had to say.
While half of iSupplyEnergy’s customer reviews on Trustpilot are rated as Excellent, 20% have below-average ratings. The reviews show that customer complaints generally concern issues with billing or negative experiences with the provider’s customer service.
“Having started with a direct debit of £68 they have increased it about every 3 months £72, £90, £120 and then finally to £168.... yes £100 more.... yet they now owe me £690. Which they have not returned despite several emails and a letter. . . .”
According to Ofgem, iSupply Energy overcharged more than 4,400 customers on its default tariff in 2019. These customers’ energy prices should have been protected by the price cap set by Ofgem. The provider must now refund the affected customers and pay 1.5 million to Ofgem’s redress fund for its failings.
Tariffs and prices
iSupplyEnergy offers an extensive selection of green gas and electricity tariffs for customers with both credit and prepayment meters. Tariffs are either fixed (with guaranteed prices for the length of the contract) or variable (in which prices are subject to change), and they always include two elements: unit rates and standing charges. Let’s take a look at some of iSupply Energy’s available tariffs.
These tariffs are no longer offered For up-to-date pricing information, please contact the new supplier.
If you have a first or second-generation smart meter, the meter will lose its smart functionality with iSupply Energy. The meter will still work — it will just function as a traditional meter and you will need to submit the meter readings manually. Customers can submit readings either by calling iSupplyEnergy or at any time through their online account.
Once iSupplyEnergy accounts go live with EDF Energy, customers with smart meters will be contacted by their new provider to confirm if the meter will have smart functionality. Customers who want to have a smart meter installed will be able to book a free installation with the new energy supplier. EDF Energy says it is aiming to have smart meters installed for all customers by the end of 2020.
iSupplyEnergy claims to provide 100% renewable energy. Its electricity is generated by renewable sources, like wind and solar power. The gas sources, however, are not actually renewable. iSupplyEnergy instead offsets the carbon that is produced by investing in projects that reduce carbon emissions — so to compensate for every tonne of CO2 emitted, a tonne is also removed through the projects.
The UK’s average fuel mix consisted of just 32.8% renewable energy between April 2018 and March 2019. This percentage is up by almost 4% from the year before. We hope that more energy companies join iSupply Energy in providing 100% renewable energy in order to help the UK reach net zero carbon emissions by 2050.
