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

An energy performance certificate for a flat in a block most often costs PLN 250, while typical quotes from assessors fall within the PLN 200 ‑ 330 range. You will pay about PLN 450 for a detached house and about PLN 1,250 for an entire multi-family building. The certificate is valid for 10 years and is required when selling or renting out a property.

An energy performance certificate may seem like a formality, but since 2023 it has been difficult to sell or rent out a flat without one. Prices in adverts look similar, starting “from” several hundred PLN, but the scope varies: some providers include travel and an inspection, while others charge for them separately. We compare assessor price lists for a flat, house and entire building, and explain what to prepare to avoid overpaying.

How much does an energy performance certificate for a flat in a block cost?

An energy performance certificate for a flat in a block most often costs PLN 250, according to 5 assessor price lists collected by indekscen.pl, while half of all quotes fall within the PLN 200 ‑ 330 range. A flat is the cheapest option because the assessor only evaluates one unit, and can often obtain information about the building’s walls, roof and heating from the property manager or housing co-operative.

The cheapest quotes, starting at PLN 129, are usually for remotely arranged services that include travel for an inspection within a large city. The most expensive, reaching PLN 400, apply to properties without documentation or urgent orders. Detailed quotations from price lists are available at energy performance certificate.

How much does an energy performance certificate for a detached house cost?

An energy performance certificate for a detached house costs about PLN 450, which is clearly more than for a flat. For a house, the assessor must describe the entire building: walls, roof, ground floor, windows, heat source, ventilation and hot water. A certificate for an entire multi-family building, commissioned by a homeowners’ association or developer, has a median price of PLN 1,250.

Property type	Certificate price	What affects the price
Flat in a block	PLN 200 ‑ 330	building documentation from the property manager
Detached house	about PLN 450	floor area, building shape, heating
Multi-family building	about PLN 1,250	number of units, documentation
Home energy audit (a different document)	PLN 1,350 ‑ 1,800	scope of modernisation options

Is an energy performance certificate compulsory?

An energy performance certificate has been compulsory when selling or renting out a flat or house since 28 April 2023. The owner provides it to the buyer or tenant, and when a property is sold, the notary records this in the deed. The requirement also applies to adverts: a property sale or rental advert should include information about its energy performance if a certificate has been prepared.

A certificate is not required when a flat is transferred as a gift or inheritance, or when you rent out a room rather than the entire property. The regulations provide for penalties if a certificate is not supplied, but in disputed cases, consult a notary or lawyer, as the details depend on the type of agreement.

Who is exempt from the energy performance certificate requirement?

Exemptions from the energy performance certificate requirement include listed buildings, residential buildings used for less than four months a year, such as summer houses, detached buildings with a usable floor area below 50 m², places of worship and industrial buildings with low energy demand. A typical flat in a block or year-round house does not qualify for these exemptions.

What is required to issue an energy performance certificate?

To prepare an energy performance certificate for a flat, the assessor needs some basic information. The more information you provide, the faster and more cheaply you can obtain the document:

1. The building’s address, floor area and year of construction, preferably with a floor plan of the flat.
2. Information about heating and hot water: district heating, gas boiler or electric heating.
3. The type of windows and the year they were replaced.
4. Building documentation from the housing co-operative or homeowners’ association: wall insulation, roof and ventilation.
5. An inspection of the property. The regulations require the assessor to inspect the property, so ask whether travel is included in the price.

Missing documentation does not prevent a certificate from being prepared, but the assessor must then make more assumptions or inspect the property more thoroughly, which increases the price.

Online and low-cost energy performance certificates: what should you look out for?

An online energy performance certificate usually costs towards the lower end of the range, starting at PLN 129, because the company collects information through a form and photographs. Cheap does not necessarily mean poor quality, but check three things: whether the assessor is listed in the central register, whether the certificate will be entered in the register, for which you will receive a number, and how the required inspection will be carried out.

You can obtain the cheapest energy performance certificate if you have a complete set of documents and do not need it by tomorrow. If the homeowners’ association already has a certificate for the entire building, ask the property manager, as this may reduce the price for your flat.

How long is an energy performance certificate valid?

An energy performance certificate is valid for 10 years from the date it is prepared. It expires sooner if alterations or renovations change the building’s energy performance, for example after replacing the heat source or insulating the building. With a cost of about PLN 250, the expense is spread over an entire decade of sales and rentals.

What does an energy performance certificate contain and how do you read it?

An energy performance certificate primarily shows annual energy demand in kilowatt-hours per square metre of floor area. The three most important indicators are:

• EU (usable energy): the amount of energy required for heating and hot water, regardless of the heat source. It reflects the quality of the walls, windows and ventilation.
• EK (final energy): the amount of energy that must actually be purchased after accounting for the efficiency of the boiler or district heating substation. This figure is the closest to actual bills.
• EP (primary energy): an environmental indicator compared against regulatory requirements for new buildings.

The lower the values, the lower the running costs. The certificate also states the proportion of renewable energy, CO₂ emissions and recommendations for improvements. For a buyer, it is a quick way to compare two flats, one in a prefabricated concrete block and one in a new building: the difference in EK translates directly into heating costs over the years.

An energy performance certificate is neither a technical condition assessment nor a valuation. It will not tell you whether the electrical installation is safe or how much the flat is worth. When buying a property, it should therefore be treated as one of several documents, alongside the land and mortgage register, certificates from the housing co-operative and, where applicable, a valuation report.

Energy performance certificate, audit and valuation report: what is the difference?

An energy performance certificate is a straightforward information document assessing energy consumption. energy audit is a more comprehensive analysis presenting modernisation options, required for programmes including Czyste Powietrze, and usually costs PLN 1,550. In turn, property valuation report (a formal valuation report) determines the value of a flat, for example for a bank, and costs about PLN 900.

These are small amounts compared with the price of a flat: a typical flat in Poland currently costs PLN 470,000. Current prices in cities are available in the article flat prices in the largest cities, while the costs of a notarial deed are covered in how much does a notary cost.

How can you avoid overpaying for an energy performance certificate?

• Ask whether the price includes travel and an inspection. This is the most common hidden surcharge.
• Prepare the documents before ordering: the floor plan, year of construction, and information about the heating and windows.
• Check the assessor in the central register and ask for the certificate’s registration number.
• Order in advance. An express service may cost extra.
• Do not confuse a certificate with an audit. A certificate is sufficient for a sale or rental.
