Shell Energy supplied more than 700,000 homes when it bought First Utility to become a home energy company in 2018. That number rose to close to one million when it bought Hudson Energy Supply, the parent company of supplier Green Star Energy, in October 2019.

Originally, the supplier kept the name First Utility but it rebranded as Shell Energy in April 2019 – a year after it was bought out by Shell.

Shell Energy says all customers get 100% renewable electricity, as well as fuel discounts. Customers who sign up to the Shell Go+ rewards programme get a 3% discount on fuel at Shell service stations; this is valid on up to 60 litres of fuel per household per month. It also gives customers 'personalised offers' and 'other surprises'.

In July 2020, the Advertising Standards Authority (ASA) banned a Shell Energy radio ad for Shell Go+ for being misleading. The ASA ruled that the ad didn't make it clear that it was for a rewards programme that would offset the carbon emissions of the fuel members bought rather for a fuel that was carbon neutral in itself.

Shell Energy took on the customers of smaller suppliers Green and Usio Energy when they stopped trading.

The supplier also sells broadband and smart home technology.

Which? verdict on Shell Energy

Shell Energy is among the biggest 10 energy firms but not among the best, according to customers in our survey. It can be found in the bottom half of our table. However, it ranks higher than all the traditional big firms. 

Customers found Shell Energy’s bills accurate, and its ‘good’ rating on this aspect equalled that of four of the firms ranked in the top 10 overall.

Some 73% of customers said the accuracy of its bills was either ‘good’ or ‘excellent’, compared with an average of 78% across firms (but 90% for the highest-scoring supplier overall in this category).

It has an app where customers can input their own meter readings, so there shouldn't be any need for estimated bills.

On every other aspect we asked about – bill clarity, customer service and its handling of complaints – its ratings were average.

It resolved 46% of complaints on the same or next working day in the first half of last year. While it’s far from the worst, the best firms manage to solve 90% or more in the same timeframe.

Some 22% of customers said that it offers 'excellent' value for money, but other firms' customer feedback was far better. The highest percentage for this category was for Avro Energy and Octopus Energy, which were rated 'excellent' for value for money by 38% of their customers in our survey.

Shell Energy offers a range of tariffs, including different-length fixed deals. In June 2020 it launched a 100% carbon neutral tariff including carbon neutral gas as well as the standard 100% renewable electricity.

Its bills have always been accurate and easy to understand.

It offered a good deal at the time and I get reward incentives.

In our September 2020 energy companies' call waiting snapshot investigation, Shell Energy answered the phone in 4 minutes 6 seconds, which was quicker than the median average wait time for all 31 companies we called (5 minutes 57 seconds).

It also offers live chat, but here it didn't do so well in our investigation. Of the 18 companies we contacted this way, it was the slowest, responding in 33 minutes 39 seconds. The average was 3 minutes 6 seconds. For comparison, Outfox the Market averaged 10 seconds for a response.

Pros: Customers generally think its bills are accurate

Cons: Customer service is only average; slowest to respond to live chat in our snapshot investigation

Can you join Shell Energy with a prepayment meter?

Yes, Shell Energy can support customers both with traditional prepayment meters and smart prepayment meters. 

Customers with smart prepayment meters can top-up online and check their credit balance on their digital in-home display.

Shell Energy in the news

Shell Energy in 2021

September: Shell Energy took on 255,000 customers from Green when the smaller supplier stopped trading.

March: Shell Energy is paying over 225,000 customers £1.2m after overcharging them when they switched supplier or tariff between 2013 and 2020. It was one of 18 energy firms found by regulator Ofgem to have failed to uphold these rules. Over 1 million customers were affected.

Shell's affected customers will receive £5.39 each, on average. This includes reimbursing customers and paying some compensation.

Shell Energy in 2020

December: Shell Energy reported a loss of almost £32m for 2019, in part blaming falling customer numbers as a result of lower prices being offered by other suppliers.

Sky News reported that Shell Energy is the preferred bidder to take over Post Office broadband, which the Post Office has decided to sell to focus on its core businesses.

July: The Advertising Standards Authority banned Shell Energy's radio ad for its Shell Go+ loyalty scheme saying it implied that it was a carbon neutral fuel rather than a loyalty scheme that offset the carbon emissions of the fuel its members bought.

Shell Energy in 2019

October: Shell Energy bought Hudson Energy Supply, including its domestic retail arm Green Star Energy, in October 2019. It's reported to have paid up to £8.5m. 

Shell Energy gained 200,000 household customers. 

June: Shell Energy said it will pay customers a total of £190,000 in compensation after Ofgem found that First Utility had overcharged some customers between January and March 2019. 

Some 12,000 customer accounts received £10 per fuel to refund the amount they were incorrectly charged above the default or standard tariff cap, plus compensation. 

Another 5,600 accounts received £5 compensation per fuel because their requests to switch to a cheaper payment method were delayed so that they paid more than the level of the price cap for longer. 

Shell Energy also paid £200,000 into Ofgem's redress fund. 

March: First Utility rebranded as Shell Energy. Shell said all 700,000 customers would automatically have 100% renewable electricity as part of their tariffs, as well as a discount at Shell service stations. 

First Utility also announced it would increase prices for customers to the maximum allowed under the new price cap from 1 April 2019. If you were on its standard tariff, and used a medium amount of gas and electricity, this means you could have paid around £1,254 per year.
