Shell Energy supplies more than 700,000 homes, but that number is set to rise to close to one million, after Shell Energy announced that it has bought Hudson Energy Supply, the parent company of supplier Green Star Energy in October 2019.
Originally, this supplier was called First Utility, but it rebranded as Shell Energy in March 2018, a year after it was bought out by Shell.
Shell Energy says all customers get 100% renewable electricity, as well as fuel discounts. Customers get 3% discount on fuel at Shell service stations; this is valid on up to 60 litres of fuel per household per month.
Plus Shell Go+ rewards programme gives customers 'personalised offers' and 'other surprises and rewards'.
Usio Energy customers were switched to the brand in October 2018, after the smaller supplier stopped trading.
Shell Energy 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. Since Shell bought the company, it has moved from mid-table (two years ago) to the bottom 10 this year.
Customers found Shell Energy’s bills accurate, and its ‘good’ rating on this aspect equalled that of firms ranked in the top 10 overall.
Some 87% of customers said the accuracy of its bills was either ‘good’ or ‘excellent’, compared with an average of 83% across firms (but 63% for the lowest-scoring supplier overall).
It has an app where customers can input their own meter readings, so there shouldn't be any estimated bills.
On every other aspect we asked about, its ratings were average, and one area was considered poor by customers.
This area was customer service. The best firm's customer service achieves a five-star rating, while Shell Energy’s gets two stars. While 67% of customers said its customer service was good or excellent, this compares with 77% of customers on average across all firms rated.
On other aspects – how clear and easy its bills are, how it handles complaints, its digital tools and value for money – Shell Energy achieved average ratings.
It resolved between 49% and 66% 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 more than 80% of complaints in the same timeframe.
Some 21% of customers also said it's 'excellent' value for money, but other firms' customer feedback was far better. The highest percentage for this category was Pure Planet, which was rated 'excellent' value for money by an impressive 47% of its customers in our survey.
Shell Energy offers a range of tariffs, including different-length fixed deals, and one including a smart thermostat.
Pros: Customers generally think its bills are accurate
Cons: Customer service is poor, according to those who use it
