LPG tank certification: 2026 cost, recertification or tank replacement

indekscen.pl editorial team · published 30 September 2026 · prices according to the 5 October 2026 index

LPG tank certification (recertification) most often costs PLN 250 (typically PLN 240 ‑ 350) and extends the tank's validity for another 10 years. The median cost of replacing the tank with a new one at a garage is PLN 715 (typically PLN 640 ‑ 780), so recertification is clearly cheaper, provided the tank is in good condition.

Every LPG tank in a car has an expiry date stamped on its nameplate. When it expires, the owner has two options: recertify the old tank or replace it with a new one. The difference in price is severalfold, so it is worth knowing when the cheaper option will suffice. We collected prices from guides and LPG garage price lists and compared the two options side by side.

How much does LPG tank certification cost in 2026?

LPG tank certification most often costs PLN 250, according to 3 sources collected by indekscen.pl, with a typical range of PLN 240 ‑ 350. The cheapest garages charge from PLN 200, while the most expensive charge up to PLN 500. The price depends on the garage, city, type of tank and whether it needs to be removed.

In everyday language, LPG tank ‘certification’ and ‘recertification’ mean the same thing: an inspection after which the tank is approved for use for another period. The data and sources are available at lPG cylinder recertification.

LPG tank recertification or replacement: which is better value?

Recertifying an LPG tank is several times cheaper than replacing it with a new one: PLN 250 compared with PLN 715, based on median price-list figures. Replacement makes sense if the tank is corroded or damaged, has already been recertified once, or the garage recommends fitting a new tank with a new multivalve anyway.

Median and typical range from public price lists, as at 5 October 2026. Each price includes a source and quotation on the service page.

Situation	Which option to choose	Typical cost
Tank is 10 years old, with no corrosion, first recertification	recertification	PLN 240 ‑ 350
Tank is corroded or dented	replacement with a new one	PLN 640 ‑ 780
Tank has been recertified once, 20 years since production	replacement with a new one	PLN 640 ‑ 780
Tank failed recertification	replacement with a new one	PLN 640 ‑ 780

The cheapest replacement, from PLN 461.25, usually applies to a cylindrical tank. Toroidal tanks fitted in the spare-wheel well are more expensive and cost up to PLN 950 in price lists. Details are available at replacement of an automotive LPG cylinder.

LPG tank certification: how many years is it valid for?

An LPG tank in a car is valid for 10 years from its production date, and recertification extends its validity for another 10 years. A tank is usually recertified only once, so it must be replaced 20 years after production. The production date and expiry date are shown on the tank’s nameplate and, after recertification, also on a new plate or in the inspection report.

The period is calculated from the tank’s production date, not from the date when the system was installed. If the system was fitted to a used car or the tank was stored for a long time, it may expire sooner than you expect.

Does an LPG tank need to be replaced after 10 years?

An LPG tank does not have to be replaced immediately after 10 years: recertification for around PLN 250 is sufficient if the tank is in good technical condition. Replacement becomes necessary if the inspector does not approve the tank for continued use or if 20 years have passed since its production.

In practice, some drivers choose replacement after the first 10 years anyway. There are usually three reasons: rust on a tank fitted underneath the car, a desire to replace a cylindrical tank in the boot with a toroidal one in the spare-wheel well, or plans to keep driving the same car for longer. A new tank provides peace of mind for another 10 years without recertification, but costs several times more.

How much does it cost to replace an LPG tank with a new one?

Replacing an LPG tank with a new one at a garage usually costs PLN 640 ‑ 780, including installation, while the median from 4 price lists is PLN 715. The price is mainly affected by the type of tank: a cylindrical tank is cheaper than a toroidal one. Some garages price multivalve replacement separately, so check whether it is included when comparing quotes.

What should you do when LPG tank certification is about to expire?

When LPG tank certification is about to expire, you must arrange recertification at an LPG garage or have the tank replaced before the deadline. Once it has expired, the vehicle will fail its technical inspection, and driving on LPG with an expired tank is against the law.

Steps to follow:

1. Check the date on the tank’s nameplate, preferably a few months before it expires.
2. Book an LPG garage that works with a technical inspection authority inspector and ask for the total cost including removal.
3. Use up the gas in the tank before your appointment if requested by the garage.
4. Collect the documents confirming recertification or installation of a new tank.
5. Show them to the vehicle inspector at the next technical inspection.

Regulations and penalties for expired certification may change, so it is worth confirming the details with a vehicle inspection station.

What does LPG tank certification involve?

LPG tank certification involves an inspection by an inspector from the Transportowy Dozór Techniczny (TDT, Polish Transport Technical Supervision Authority) at an LPG garage. The mechanic usually removes the tank, and the inspector assesses its condition, including corrosion, mechanical damage and markings. If the tank passes the inspection, it receives a new expiry date and a document for the vehicle inspector.

The entire process usually takes from a few hours to one day because garages group several tanks together for a single visit by the inspector. It is also worth replacing the multivalve if it is old and having the entire system inspected.

How much does a technical inspection for a car with an LPG system cost?

A technical inspection for a passenger car with an LPG system costs PLN 245, compared with PLN 149 for a car without LPG. This is a statutory fee and is the same throughout Poland. The vehicle inspector also checks the tank’s certification, so recertification must be completed before the inspection.

It is also worth arranging a separate annual car LPG system inspection at an LPG garage. It usually costs PLN 145 ‑ 170, with liquid-phase and vapour-phase filters charged separately. Read more about technical inspection costs in the article how much does a car inspection cost.

Is it worth continuing to drive on LPG with an old tank?

Driving on LPG is usually still worthwhile, even if the tank needs to be replaced. Replacing the tank for PLN 715 costs a fraction of a new system: a fourth-generation lPG system installation usually costs PLN 3,300 ‑ 3,700. With high annual mileage, the difference in fuel prices quickly covers the cost of recertification or replacement.

The situation is different when the car is more than 10 years old and the system is causing problems. Tank replacement may then be only part of the expense, as the reducer, injectors and calibration may also need attention. Ask the garage to inspect the entire system before making a decision.

How can you avoid overpaying for LPG tank recertification?

• Compare prices with and without removal. Some garages quote only the inspection price and charge separately for removal and refitting.
• Ask about the multivalve. If the garage recommends replacing it, ask for it to be listed separately in the quote.
• Do not wait until the last day. It is best to coordinate the technical inspection date and the tank’s expiry date so that everything can be done within the same week.
• When replacing the tank, ask about its type. A cylindrical tank in the boot is cheaper, while a toroidal one occupies the spare-wheel well and costs more.
