The table below shows the breakdown of Boost’s scores from our latest survey.
|Value for money|
Based on a survey in September 2021 of 113 Boost Energy customers.
Pros: Customers seem happy with their payment options
Cons: Slow to pick up the phone or answer emails in our snapshot investigation
It’s the fourth time we’ve been able to include Boost in our annual energy company survey. It gets a fair rating from its customers on half of the measures.
Boost's customers gave it three stars for bill clarity and value for money - it doesn’t promise big savings, but ‘to be 100% here for you’.
Customers comments were positive about the different payment options Boost offer and lots felt their statements were clear.
I love the option to see how much you're spending on both gas and electricity
Unfortunately it only received two stars for bill accuracy and customer service.
When it came to customer service overall, 70% of Boost's customers said they satisfied overall with its customer service and 54% told us its quality of customer service was good. In fact, Boost had the highest proportion of customers in our survey saying they had reason to complain in the previous 12 months at 58%. Almost six in 10 (59%) of these customers who had reason to complain between October 2021 and October 2022 did so about bills or statements and 30% complained about customer service.
Around half of the electricity Boost sells is matched with renewables. It doesn’t generate any itself or buy any directly from renewable generators.

Boost is part of Ovo Energy, which told us it has ‘chosen to invest in the smart grid because we believe that the renewable energy generation sector is well funded and growing fast’ and because ‘there is very little investment in the smart grid, which is urgently needed if we want to bring more intermittent renewable energy onto it’. .
