Eon is the next supplier to raise energy pricesHikes of 18.1% in gas and 11.4% in electricity

05 August 2011

Eon is the fourth of the 'big six' energy companies to announce an increase in prices. The price rises will take effect from 13 September - with gas prices up by 18.1% and electricity by 11.4%.

Richard Lloyd, executive director of Which? said: 'Eon's 7.4 million customers won't be surprised to see their supplier following the rest of the 'big six' energy companies in the latest round of price hikes.'  

He added: 'Suppliers have repeatedly blamed rising wholesale energy costs for the spate of hikes, but this is cold comfort to those struggling to manage tight household budgets.'

Which? research shows that rising energy prices are consumers' number one financial concern. The latest round of rises will add an estimated £157 to the average household bill.

Previous Eon price hikes

Although the rises were on the horizon, customers will still be reeling from price rises that took effect in February 2011, when Eon raised its prices in line with the 'big six'. Gas went up by 3% and electricity by 9%, adding an extra £62 on average to an annual bill.  

Although the price rises won't take effect until the end of summer, Richard Lloyd has urged energy suppliers to act now to consider ways that they might help customers lower their bills in the run up to winter. 

He said: 'There is a real risk that millions will struggle to heat their homes this winter, so it's crucial that suppliers do more to help their customers get on the cheapest available tariff, the most economical payment method, and to take up free energy efficiency offers.'

Energy price rise season

The price hike is just one in a string of rises announced by energy companies this summer. 

Back in June, Scottish Power was the first of the major energy companies to announce it would be increasing gas prices by 19% and electricity charges by 10% from 1 August.

Earlier this month, British Gas said it would be raising gas prices by 18% and electricity prices by 16% from 18 August. They were followed by Scottish and Southern Energy (SSE) on 21 July. 

Honesty on energy prices

Which? is currently calling for energy companies to make energy tariffs clearer and more transparent. Even if wholesale prices do increase, with simple tariffs customers can more easily compare prices and switch. 

We're also asking the government to help increase competition in the energy market – by clearing the way for new suppliers they could increase competition and potentially help drive improvements in services and lower prices.

Lower your gas and electricity bills

You can compare energy prices and switch to a new gas and electricity supplier on Which? Switch. People who switched with us between 1 October and 31 December 2013 are predicted to save an average of £234 a year on their bills.
