Which? verdict on Bulb Energy
Bulb Energy was included in our energy survey for the first time last year, and in both years it has been well rated by customers. It’s growing fast – 95% of its customers we surveyed said they’d joined it in the past two years – but still keeping customers content.
This year, Bulb's customer score is well above average, but it’s still a few percentage points away from the top of the table.
Customers are most impressed by its online customer service and value for money; both receive five-star ratings. Overall, 10 firms were rated excellent value for money by their customers.
Across the other measures we asked about, including billing, phone customer service and complaints handling, Bulb does a good job according to customers.
In fact, Bulb’s customers were second most likely (after top-scoring Octopus) to say its complaints handling was excellent.
Bulb also has one of the lowest levels of complaints among companies included in the survey. Plus it resolved all complaints it received in the first six months of last year within eight weeks. While that may not sound speedy, the worst companies resolved fewer than 80% in the same time period.
However, it was the second-slowest to answer the phone on average in our snapshot investigation into energy companies' call waiting times. In previous years it was much faster. This year it took 19mins 2secs on average to pick-up. Only Scottish Power was slower, taking 21mins 24secs on average.
We also tried its live chat in the hope that this would get us a faster response. Unfortunately, Bulb’s live chat was unavailable on 11 of the 12 occasions we tried. On the only occasion it worked, it took us 10 minutes to get a reply. Bulb wasn’t the only company with poor live chat availability though – Utilita also only had live chat available on one occasion we tried.
Pros: Customers rate it excellent value for money, with excellent online customer service
Cons: Slow to respond on the phone in our snapshot investigation

December: Bulb announced that it had 870,000 customers and that its gross profit rose from £1.1m to £12.1m in a year. But it revealed that its losses grew faster in the same time period, which it said were due to the cost of growing its customer based and developing new technology.
