Fuel prices: what the acts require

Published 2026-08-12.

Why does the price on a station's sign read one thing in the morning and another by evening? Is that even allowed? The short answer is yes — no act in force forbids it. This page collects what stations are required to do, what the law does not require of them, and what the Seimas is currently trying to change. Every claim comes with a link to its primary source. The page states facts and gives no advice.

Why prices move

Most of a fuel price is set before the fuel reaches the station. By the Competition Council's figures, in March 2026 the wholesale price made up about 88% of the petrol price and about 93% of the diesel price excluding taxes — the pump price first of all follows the world market. The same council announced in April 2026 that it had found no fuel-pricing infringements. The statement's page on kt.gov.lt could not be verified, so no link is given here.

March 2026 showed how this works in practice: Brent oil rose from 78 to 114 US dollars per barrel within the month (2026-03-02 to 2026-03-30) — the figures are published by the Lithuanian Energy Agency. By the agency's expert assessment, that oil jump on its own explains about 0.21 €/l. Yet over the same period the wholesale diesel price rose 0.42 €/l (+62%) and petrol 0.24 €/l (+46%). The gap between what oil explains and what wholesale actually rose is, in the agency's assessment, margins and other factors.

What the acts require

Two main rules protect the buyer. First: the price must be displayed, clearly visible and legible — required by the Rules on the labelling of goods and indication of prices (order No. 170 of the Minister of Economy, 15 May 2002; consolidated version in force since 2021-05-25; points 27 and 33).

Second: a seller may not charge a price other than the one displayed. That is a misleading commercial practice under Article 5 of the Law on the prohibition of unfair commercial practices against consumers (No. X-1409). It is supervised by the State Consumer Rights Protection Authority (VVTAT), and Article 13 provides the fines: up to 3% of annual revenue (capped at €100,000), and up to 6% (capped at €200,000) for a repeat infringement within 12 months.

What no act requires

Now for what the law does not say, though many assume it does. There is no special rule that the price on a station's sign must match the price at the pump or the till — only the general price indication and misleading-practice provisions described above apply.

There is also no limit on how often a station may change its prices. The sign can be rewritten several times a day without breaking any law.

The one price duty written specifically for stations is to report: since 8 April 2026, stations submit their 95 petrol, diesel and LPG prices to the Lithuanian Energy Agency by 10:00 every working day, and the agency publishes them — the agency's announcement.

What the Seimas is considering

An attempt to rein in price moves is already on the table. Bill XVP-1450, registered on 29 April 2026, would add Article 19-4 to the Energy Law: fuel prices could be raised no more than once per day, at 10:00, and lowered at any time.

On 14 May 2026 the Seimas approved the bill after presentation (75 for, 3 against, 12 abstained). But on 27 May 2026 the committee paused its consideration, awaiting information from the Ministry of Energy (the sitting's minutes). As of 2026-08-12 the bill still stands there: consideration paused, the law not adopted.

Every member's vote is public. The 75 votes in favour came from the Social Democrats' group (33), "Nemuno aušra" (14), the Democrats "Vardan Lietuvos" (10), the Farmers and Christian Families Union group (7), the Homeland Union–Lithuanian Christian Democrats (6), the mixed members' group (3), the Liberal Movement (1), and the Speaker of the Seimas. The three votes against were cast by Liberal Movement members Simonas Gentvilas, Simonas Kairys and Jevgenij Šuklin. Twelve abstained — ten members of the Homeland Union–Lithuanian Christian Democrats group and two Liberals; every name is in the official voting record.

A separate idea — a maximum fuel price mechanism — was submitted to the Seimas by the President of the Republic on 7 April 2026 — the Seimas chancellery's announcement.

On weekend price rises

It is often said that fuel gets dearer before weekends and public holidays. There is no official study confirming it — so this page does not claim it either.
