Announcing this latest tariff change, David Smith, director at Firmus, said the energy supplier continues to experience “elevated wholesale prices while the conflict in the Middle East remains unresolved”.
“Over the last year or so we have reduced our tariffs on three separate occasions, bringing tariffs down by over 27% and saving customers around £300 on average per annum.”
Smith said while the increase is “unwelcome”, it means that customers’ bills will “now be roughly the same as this time last year and still significantly below where they had been in previous years”.
Leigh Greer, head of security of supply and markets regulation at the Utility Regulator said: “We understand this increase in energy costs is not welcome news for consumers.
“Unfortunately, the impact of continued and sustained rises in the wholesale cost of energy, caused by the conflict in the Middle East, has resulted in these increases.
“The conflict has impacted energy prices globally, and has already affected home heating oil, petrol and diesel prices.”
