Which? verdict on Flow Energy
Flow Energy's ratings were generally 'good' across most of the categories, bar 'helping customers to understand and reduce their energy use', which only received three stars out of five. But with 80% of its customers still 'satisfied' with the company, it could be doing worse.
It was its billing accuracy that impressed customers the most, with a huge 94% of respondents rating it either 'good' or 'excellent'. This is one of the highest percentages of the 30 energy suppliers included in our survey.
Many customers praised the 'great' system that Flow Energy use (monthly online readings), citing it as the reason for such accurate bills. One customer said: 'They have a great system were I supply a reading every month to make sure my bills are accurate.'
When it comes to 'value for money', customers seem satisfied. With an overall four out of five star rating and 80% of customers classing it as either 'good' or 'excellent'. Customers' comments on this category include: 'Prices are reasonable' and 'cheaper rates than elsewhere.' But there's 'always room for improvement', as another customer reported in the survey.
Customer service, both over the phone and online, were given four out of five stars.
Unfortunately we didn't receive enough responses to give 'complaints handling' a star rating.
In a separate investigation by Which?, we found that although Flow had one of the lowest levels of complaints per 1,000 customers in the first half of last year, it’s not the speediest to resolve them. Just 11% were completed within two days in the first three months of 2018, and only 17% for the following three months.
All of Flow Energy’s tariffs come with 50% renewable electricity, but you can pay for an optional upgrade to bring this up to 100%.
Pros: Low levels of complaints, all tariffs have 50% renewable electricity
Cons: Not the speediest to resolve the complaints it does get

Flow Energy in the news
Flow Energy announced its second price rise of 2018. Customers on its standard variable tariff who use a medium amount of energy will see their gas prices increase by 14.8%, and their electricity prices increase by 6.9%, on average. Overall this will add £115 per year to customers' bills.
The price rise will apply from 11 November.
Flow said that wholesale prices had continued to increase since its previous price rise 'meaning that to ensure we can continue to provide our customers with the service that they deserve, we have had to increase our prices again'.
Flow Energy announced it will raise prices for customers on its variable tariff from 20 August. The 7% increase on dual-fuel prices will see customers pay £72 extra per year, on average.
It blamed wholesale price rises of 32% since April 2017 for the increase.
