On Thursday 24 September, unleaded 95 was selling for an average of 2.181 euros per litre in Attica. Diesel was priced at 2.205 euros. These are the latest official figures from the Liquid Fuels Price Observatory. On the same day last year, unleaded petrol cost €1.730 and diesel €1.519. On Wednesday 30 September, the government is expected to announce a new subsidy for diesel. A second round of subsidies for heating oil is due to follow on 14 October.
How much have prices risen?
Within four weeks, the price of unleaded petrol in Attica rose by 16.5 lepta, from 2.016 euros on 27 August to 2.181 on 24 September. Diesel rose even further, by 18.8 lepta, from 2.017 to 2.205. Compared with last year, unleaded petrol is 45 cents (26 per cent) more expensive and diesel 69 cents (45 per cent) more expensive. LPG is rising much more gradually, to 0.987 euros from 0.916 last year.
In practice, a 50-litre fill-up of unleaded petrol currently costs around 109 euros, compared with 86.50 last year. For a diesel car, the same 50 litres has gone from 76 to 110 euros.
Where does every euro go in the pump?
According to the Observatory’s weekly bulletin for 18 September, more than half the price of unleaded petrol consists of taxes. Of the nationwide average price of €2.19, €1.14 (52 per cent) consists of taxes and duties. Excise duty alone amounts to 70 lepta per litre, and VAT at 24 per cent is charged on all the remaining amounts. €0.90 (41 per cent) is the refinery price, and around 15 lepta goes to distributors and petrol stations.
For diesel, the ratio is reversed, as the excise duty is lower, at 41 lepta. In this case, 53 per cent of the price is the refinery price, which rose by 12.4 lepta in just one week, from 10 to 17 September. As a result, diesel now costs more than unleaded petrol.
What to expect on Wednesday
According to information from ERT, three announcements are due to be made on Wednesday: one from the Ministry of Finance and one from each of the country’s two refineries. The government is considering a subsidy of 10 to 15 lepta per litre for diesel, to which the refineries will add approximately 5 lepta. No government subsidy is expected for unleaded petrol. The refineries are expected to continue offering a discount of around 10 lepta. The amounts will be deducted from the daily price and reviewed every 15 days. The final figures will be announced on the same day.
On 14 October, one day before heating oil goes on sale on the 15th of the month, announcements are expected regarding a subsidy of around 30 lepta per litre. The stated target is a final price of 1.70–1.75 euros per litre. A flat-rate increase of 15–20 per cent in the heating allowance is also expected on the same day. Heating oil is available from 15 October to 30 April, so the Observatory does not yet have this year’s price.
How do you view the prices at Artemida petrol stations?
Every petrol station is required to report its prices to the Price Observatory at fuelprices.gr. There, select ‘Prefecture of East Attica’ and then the municipality. The system retains the names used prior to the ‘Kallikratis’ reform. Artemida appears as ‘Municipality of Artemida’ and Spata as ‘Municipality of Spata-Loutsa’, so it is advisable to check both. HEDNO does the same in its power cut announcements. The page requires you to tick the ‘I’m not a robot’ box before displaying the prices. The free fuelGR app from the University of Thessaly displays the same data.
If the price at the pump differs from that stated by the petrol station, you can make a complaint to the Consumer Helpline on 1520.
