Replacing a gas boiler is an expense where it is easy to compare quotes that cover different things. One installer quotes labour only, another includes the boiler, while a third has added a chimney liner and design work. We break the cost down into individual items based on public price lists and articles, making it clear what you are paying for and what additional work may emerge along the way.
How much does labour cost for replacing a gas boiler?
Labour for replacing a gas boiler most often costs PLN 2,200, with a typical range of PLN 2,100 ‑ 2,500, according to 3 sources collected by indekscen.pl. This price covers a straightforward job: dismantling the old appliance, installing the new one and connecting it to the existing water, gas and chimney connections. The cheapest quotes start at PLN 900, while the most expensive reach PLN 3,500, mainly in large cities and for more complex installations.
Details, quotations from price lists and source dates are available on the gas boiler replacement page. The labour price does not include the boiler itself, chimney modifications or formalities. These are the three items most likely to double or triple the initial quote.
What is the total cost of replacing an old boiler with a new one?
In the example based on price lists, a complete replacement of an old boiler with a new one, including the boiler, labour, chimney and formalities, costs around PLN 16,500. This is an indicative figure from one complete estimate, not a median, as comprehensive quotes are rarely published. It does, however, show the proportions: labour is usually a small part of the bill, while the boiler itself costs the most.
The full cost of replacing a gas boiler consists of:
| Item | Typical cost | When it applies |
|---|---|---|
| Labour: dismantling and installing the boiler | PLN 2,100 ‑ 2,500 | always |
| New gas boiler | priced separately, depending on output and type | always |
| Chimney renovation with liner replacement | around PLN 1,100 | when switching to a condensing boiler or if the chimney is in poor condition |
| Chimney flue approval by a chimney sweep | around PLN 450 | after changing the appliance or flue |
| Gas installation tightness test | around PLN 200 | after work on the gas installation |
| Full cost in the example based on price lists | around PLN 16,500 | boiler, labour, chimney, formalities |
Do not simply add all these items together: which ones apply to you depends on the condition of the chimney and the type of boiler replacing the old one.
How much does it cost to replace a central heating boiler with a condensing boiler?
Replacing a central heating boiler with a condensing boiler costs more than replacing it with a similar model, as labour is closer to the upper end of PLN 2,100 ‑ 2,500 and chimney work is often required as well. A condensing boiler produces low-temperature flue gases and condensate, so an old masonry flue is usually unsuitable without an acid-resistant liner or a concentric flue. Chimney renovation with liner replacement costs around PLN 1,100, while a typical chimney repair costs PLN 420 ‑ 650.
The installer should also check the radiators during this replacement. A condensing boiler operates most efficiently at a lower water temperature, at which small radiators may not heat the house sufficiently. Some of them may need to be replaced, increasing the total cost.
What affects the cost of replacing a boiler?
The price of replacing a gas boiler depends primarily on the scope of work: replacing it with a similar boiler in the same location is the cheapest option. According to price lists, the most important factors are:
- Boiler type and output. A condensing boiler or a higher-output appliance means higher equipment and labour costs.
- Condition of the chimney. An acid-resistant liner, concentric flue or new system chimney is a separate and often the largest additional cost.
- Changes to the installation. Moving the boiler, installing new water and gas connections or replacing radiators extends the work.
- Formalities. Gas installation design, approval by an authorised inspector and notification to a chimney sweep.
- City. Labour is more expensive in large cities than in smaller localities.
How long does it take to replace a gas boiler?
Replacing a gas boiler with a similar model usually takes one working day, as confirmed by installers’ price lists. Switching to a condensing boiler, including fitting a chimney liner, modifying the installation and obtaining approvals, takes longer, sometimes several days. You must also allow time for the chimney inspection and tightness test, which may be scheduled separately. It is therefore best to plan the replacement outside the heating season, from May to September, when installers have more availability.
How often should a gas boiler be replaced?
A gas boiler is usually replaced after 15 to 20 years of operation, or sometimes later if it is regularly serviced. Cost rather than age is generally the deciding factor: rising gas bills, frequent breakdowns and a lack of spare parts for the old model. Gas boiler repairs usually cost PLN 275 ‑ 435 excluding parts, so two or three serious breakdowns in one season already amount to a significant proportion of the labour cost for a replacement.
An annual gas boiler inspection is necessary to keep the boiler working for a long time. It usually costs PLN 280 ‑ 300, while an inspection of a condensing boiler with flue gas analysis costs around PLN 415. A chimney inspection and gas installation inspection are arranged separately once a year. You can read more about chimney sweep rates in our article how much you pay a chimney sweep.

Is funding available for replacing a boiler?
Funding for boiler replacement is available primarily through the Czyste Powietrze programme, which supports replacing an old heat source, particularly a coal-fired boiler, with a condensing gas boiler or heat pump. The amount of funding depends on income and the scope of work, while the programme rules change from time to time, so check the current terms with your municipality (gmina) or the voivodeship environmental protection fund before signing an agreement with an installer. Some municipalities also have their own programmes for replacing obsolete high-emission boilers.
Deadlines for replacing old coal-fired and wood-fired boilers are set out in the anti-smog resolutions of individual voivodeships and vary by region and boiler class. If you have an unclassified, class 3 or class 4 boiler, check your voivodeship’s resolution, as using the boiler beyond the deadline may result in a fine.
Gas boiler replacement or heat pump?
Replacing a gas boiler has a much lower upfront cost than installing a heat pump: according to price lists, an air-to-water heat pump with installation usually costs PLN 31,800 ‑ 52,500, while installation alone, excluding the appliance, costs around PLN 9,500. A heat pump, however, has lower running costs in a well-insulated house and is eligible for higher subsidies. In a house with gas, a working installation and old radiators, a condensing boiler is usually the simpler choice. We compare a heat pump with solar panels and explain how they can be combined in the article heat pump or solar panels.
How can you avoid overpaying when replacing a boiler?
- Ask for an itemised quote: boiler, labour, chimney and approvals. Only then can you compare quotes.
- Arrange a chimney inspection before obtaining a quote. A chimney sweep will assess whether the old flue is suitable for the new boiler; this is the most common surprise on the bill.
- Ask who handles the formalities: design, approval and notification. A company that includes these in its price may work out cheaper overall.
- Check the installer’s gas qualifications and the boiler manufacturer’s warranty terms, as they often require installation by an authorised service provider and annual inspections.
- Plan the work for summer. An emergency replacement in January means fewer available dates and less scope for negotiating the price.
