Octopus Energy (2023) review: Our favourite energy supplier
A multi-award-winning energy supplier, Octopus Energy is a great all-rounder
Pros
- Renewable electricity as standard
- Supplies some carbon-offset gas
- Invests in renewable energy generation
Cons
- Not the quickest at resolving complaints
Octopus Energy launched just eight years ago but has grown rapidly. It recently became the UK’s second-largest home energy supplier after completing its purchase of Shell Energy’s home energy and broadband business. This means it will now supply 6.6 million households with renewable electricity, gas or both.
It isn’t just its green credentials that are impressive; Octopus Energy Generation claims to be one of Europe’s largest investors in renewable energy and some of its gas is carbon offset as well.
Octopus swept the board in our Expert Reviews Energy Awards 2023, scooping gongs for best supplier overall, Best Customer Service, Best Value, Best Bills and Fastest Call Centre Response. In our survey conducted in partnership with YouGov, some 79% of its customers said they would recommend it to a friend.

Octopus was ahead of its rivals in our survey for the clarity of its bills. Here, 84% said they found their bills very or fairly easy to understand compared with the next best – E.ON Next with 77%. Only 12% of Octopus customers said their bills were difficult to understand compared with 27% for the worst for this – EDF Energy.
It was also the top supplier for the accuracy of its bills – 52% of its customers said their bills were always accurate compared to 44% and 43% respectively for the next best suppliers Scottish Power and Shell Energy, which will now see its customers migrated over to Octopus.
Octopus Energy (2023) review: Customer contact
It was also head and shoulders above the rest for the speed at which it answered calls from its customers, picking up the phone in five minutes or less for 42% of them. In contrast, Scottish Power managed this for just 17% of calls. Octopus answered 12% of calls in less than one minute.

Octopus Energy (2023) review: Complaints
According to the complaints data published by the energy regulator Ofgem for the third quarter of 2023, Octopus Energy had the lowest number of complaints per 100,000 customer accounts of all the suppliers in our survey at 1,133.
It didn’t resolve them as quickly as some of the other suppliers in our survey though. Some 69% of complaints were resolved by the end of the next working day and 90% within eight weeks. Ovo Energy was the quickest at resolving complaints with an 80% next-day resolution rate and 97% resolved within eight weeks.
Ofgem complaints data
| Complaints per 100,000 customer accounts | Industry average complaints per 100,000 customer accounts | Complaints resolved by end of next working day | Complaints resolved within eight weeks |
| 1,133 | 1,578 | 69% | 90% |
Notes: Data is for the third quarter of 2023
Along with customer satisfaction and complaints, the cost of energy suppliers’ tariffs will also determine whether they’re worth switching to. There are currently very few deals that are likely to save you money compared to your suppliers’ standard variable tariffs, which are subject to the price cap set by Ofgem, and many of the best deals on offer right now are for existing customers only.
To compare costs, you should see what your current suppliers are offering existing customers as well as gathering quotes to find out how much tariffs from different suppliers will cost you based on your energy usage.
