Boost supplies pay-as-you-go customers only, and says its ‘mission is to make PAYG energy fit around your life’. 

In 2019 - the latest available figures - it served more than 350,000 homes.

It was launched in 2017, when Ovo Energy split out its prepayment energy business to ‘better serve customers’. Boost supplies both traditional and smart prepayment meters.

Customers with smart meters can top up via a smartphone app - PAYG Smart. You can also use the barcode in the app to top up in the shop and keep an eye on what you're spending by checking the top up history. 

It offers 50% renewable electricity, and its tariffs have no exit fees.

Boost customer review

Boost came 5th out of 16 energy companies rated by 8,390 members of the public in the annual Which? energy companies customer satisfaction survey.

Parent company Ovo finished higher, in joint-second position.

Customers weren't particularly impressed with any aspect of Boost's service, although they rated it higher for value for money than most of the traditional big firms and had some positive things to say about it's payment options. 

They let you pay by card or direct debit and if your electric is running out they put £5 on your account.

Which? verdict on Boost

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 value for money & bill clarity

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

Boost's bill accuracy and customer service

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.

Boost Energy PAYG smart app

Can I switch to Boost with a prepayment meter?

Yes. Boost only supplies customers with prepayment meters. You can join Boost whether you have a traditional pay-as-you-go meter or a smart one. Some smart meters will lose their smart features when you switch - Boost says it will check if you have a compatible smart meter before you switch.

If you don't already have a smart prepayment meter, Boost is installing them. It'll mean you can top-up using its app, as well as at PayPoint shops. The app also lets your schedule automatic top-ups.

You'll get an in-home display which will alert you when your credit is running low.

If you run out of credit between 4pm and 10am weekdays, at the weekend or on a bank holiday, your power won't be cut off. 

Boost offers emergency credit so your energy supplies don't cut off if you can't get to the shop. Smart PAYG+ customers automatically get emergency credit when theirs gets too low. If you don't use the Boost app (smart PAYG standard customers) you'll need to activate your emergency credit on your in-home display.

Traditional meter customers can access it via their meter.

You'll pay back any emergency credit you've used when you next top-up.

Does Boost Energy sell renewable energy?

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’.
