Ljubljana - The government has extended the regulation of heating oil prices under which retailers' margin is capped at six cents per litre. The decree entered into force today and is valid for 30 days.

The base price to which the margin is added is calculated as a 14-day average price that takes into account prices on Mediterranean markets, the euro-dollar exchange rate and several other variables.

Heating oil price regulation was introduced in November to stem the rise of energy prices. Fuel prices remain regulated as well.
