Utility settlement in a housing community: from supplier invoice and meter reading to an owner’s amount

A good settlement can be followed in both directions: from the source cost to the amount allocated to an owner, and from the owner’s amount back to the invoice, period, reading and allocation rule.

A sound utility settlement lets an apartment owner follow the calculation from the supplier’s invoice, through the meter reading and allocation method, to their own credit or additional charge. A final amount alone is insufficient. If the administrator cannot reproduce that calculation, the weakness will surface when someone complains, the board changes, or another management company takes over the building.

This guide concerns homeowners’ associations in Poland, known as wspólnoty mieszkaniowe. Its official sources were checked on 2 October 2026. Workflow controls are practical recommendations; statutory obligations carry source references. Reading the English version does not make the rules applicable to properties in another country.

Define what you are settling

Before calculating anything, identify the building, utility and settlement period. Establish who holds the supply contract: the association, an apartment owner, or another entity. Electricity supplied to an apartment under an individual contract must not accidentally enter the common property’s cost pool. Electricity for the lift, stairwell lights and shared equipment needs appropriate attribution to the common property.

Keep supplier costs, advance charges assessed to owners and payments actually received separate. They are different figures. A credit resulting from utility settlement does not automatically mean the owner has no other unpaid charges. The utility statement should explain the cost allocation result; the owner’s financial account should show the wider position of charges and payments. Combining them without explanation makes the balance difficult to understand.

The Polish Ownership of Premises Act distinguishes expenses associated with an owner’s apartment from costs of maintaining the common property. Consequently, a convenient allocation key is not a universal solution for every utility. First identify the nature of the expense and the basis of the allocation method. Then put the formula into the spreadsheet. [5]

Assemble evidence before running the calculation

Collect invoices, credit notes, contracts, tariffs applying during each part of the period, the settlement rules and the meter register. Each reading should have a meter number, apartment identifier, date, value and collection method. Preserve the original export from the reading system. A screenshot of the final table does not replace the underlying data.

Check meter replacements. When a device changes during the year, consumption includes the period recorded by the old meter and the period recorded by the new one. Record the old meter’s final value, the new meter’s initial value and the replacement report. A new meter may start at a value other than zero. Do not “correct” that value without evidence. Similarly, flag a broken device, lack of apartment access or missing reading rather than silently entering zero.

Freeze the list of apartments and parameters for the relevant period. Any floor area, ownership share or other parameter used in allocation should have an identified source. Where an apartment was sold, establish the transfer date and reading. A private handover report between seller and buyer does not settle every obligation of the association; review the documents and the accounting arrangements before changing the owner’s records.

Water: reconcile quantities before allocating costs

Where the building owner or manager is the sole customer, they must settle water and wastewater service costs. The total amount charged for water or wastewater cannot exceed the cost incurred towards the water and wastewater company. The quantity supplied to the property is generally established from the main meter. Article 26(3) provides for selecting a method of allocating the difference between main and local readings; it does not impose one universal key for every building. [1][2]

Compare main-meter consumption and total apartment consumption over matching dates. Differences may arise from common use, a leak, reading dates, measurement accuracy or incorrect data. A difference is not, by itself, proof of water theft. Check shared taps, reading periods and the completeness of the meter register before distributing the cost. A documented explanation is more useful than an unexplained line labelled “shortfall”.

The following example is illustrative. Its price and method are neither a tariff recommendation nor a statement that this method suits every property. Assume main-meter consumption of 1,000 m³, total apartment consumption of 940 m³ and a combined water and wastewater cost of PLN 15,000, with no other components. The example’s settlement rules allocate the difference in proportion to recorded apartment consumption. One apartment used 47 m³: 5% of the apartment total.

Example itemCalculationResult
Apartment’s recorded consumption cost47 m³ × PLN 15/m³PLN 705
Building’s quantity difference1,000 − 940 m³60 m³
Cost of the difference60 m³ × PLN 15/m³PLN 900
Apartment’s share of that cost5% × PLN 900PLN 45
Apartment’s allocated costPLN 705 + PLN 45PLN 750
Advance charges assessed for the periodowner accountPLN 720
Cost settlement resultPLN 750 − PLN 720PLN 30 additional charge

The building-level check should produce PLN 14,100 of metered consumption cost and PLN 900 of difference cost, totalling PLN 15,000. If the supplier charges a subscription fee, prices changed, or some uses are separately metered, extend the calculation accordingly. Do not hide those components in a rate whose derivation owners cannot see.

A tariff change or missing reading requires a recorded decision

If prices changed within the period, preserve the new tariff's effective date and the cost split supported by supplier documents. A reading on the change date helps, but may be unavailable. Explain the basis of any allocation used in that situation. Do not present estimated consumption as an actual measurement. The owner should be able to see where a reading ends and an assumption begins.

Handle an apartment's missing reading similarly. Record the reason, attempts to obtain data and the proper basis for any substitute calculation. Check the legislation and applicable building rules before using the method. If correct data arrive later, assess whether a revision is needed and how it affects other apartments. Changing one apartment's share of the difference cost can change everyone else's share. Recalculate and check the whole relevant total.

Keep duplicate invoices, previous-period corrections and meters assigned to the wrong apartment in an exception register. Give each item a task owner and resolution status. A visible list of unresolved issues is more useful than a final assurance that the totals look right.

Heating and domestic hot water need separate components

The Polish Energy Law links charges collected by a building owner or manager to covering the cost of purchased energy, fuels or heat. A heat allocation method must meet the legal requirements and fit the building’s circumstances. An arbitrary margin on purchase costs or an unexplained percentage is not an acceptable shortcut for every installation. [3]

Separate space heating from domestic hot-water preparation. Then show the fixed and variable components in line with supplier invoices and the applicable settlement rules. A cubic metre of hot water involves the water itself and energy used to prepare it; it is not equivalent to a cubic metre of cold water. Where suitable measurements are missing, determine the permitted allocation basis first. A longer formula does not make missing input data more reliable.

A heat meter and a heating cost allocator have different functions. An allocator produces units used to divide costs; it is not a stand-alone measurement of energy in GJ. Explain adjustment factors and the limitations of the chosen method. The regulation of 7 December 2021 specifies detailed conditions and information requirements for different settlement methods. Check a contractor’s statement against those requirements, as well as checking the final total. [4]

Advance charges and settlement are different activities

An advance charge helps finance expected expenditure during the period. Settlement compares the allocated cost with the advances assessed. An intelligible statement gives the period, cost, advance total, result and the way the balance will be handled. Show unpaid amounts separately. The owner should know whether the amount payable arose from higher consumption, higher prices, missed payments or a combination of these causes.

Base the next advances on available evidence: previous consumption, current prices and known changes. Do not copy last year’s amount automatically when a tariff has risen substantially. Conversely, a large additional charge for one apartment does not justify the same increase for everyone. Record the assumptions so the next settlement can distinguish a pricing issue from a forecasting or input-data issue.

The resident’s information must explain the result

Article 45c of the Energy Law requires free information about purchased-heat cost settlements for users supplied with heat, cooling or domestic hot water from a central source, at least annually. Where settlement uses the remotely readable devices specified by the Act, users must also be able to obtain consumption information free of charge once a month. These are separate obligations. [3]

The required information depends on the measurement and allocation method. The regulation provides for building and apartment data, relevant cost components, comparisons and supplementary information. Sending one figure labelled “heating” is insufficient. Check sections 9 and 10 against the method actually used in the property. [4]

In practical terms, explain abbreviations and identify the person or contact channel responsible for complaints. State which documents support checking the cost. When sharing evidence, avoid sending every resident the complete account list for all apartments. An owner needs evidence for their own calculation and the necessary building context, rather than an incidental list of other people’s unpaid charges.

Close the period after checking the evidence

Check the supplier cost pool, apartment completeness, reading dates, allocation key and rounding. The total of apartment settlements should reconcile to the relevant cost pool. Describe each manual correction with its reason, supporting document, author and date. Retain the version sent to residents. A later revision must not erase the previous calculation’s history.

For a complaint, reconstruct the specific path: cost document, reading, allocation method, advances and result. If an error affects every apartment, correct the whole affected scope rather than only the apartment whose owner complained. Include settlement rules, the meter register, reading sources, completed statements and open complaints in the administrator’s handover pack. The next period can then start with checked information rather than assumptions.

Check WM Administrator’s scope against your company’s settlement process. Start by deciding how the cost, document and apartment will be connected, and who will approve the result before distribution.

Another reconciliation example: an input cost of PLN 9,842.17 should reconcile with the total allocated to units, common or unallocated amounts, corrections and an explicit rounding difference. Do not remove an unexplained difference by manually adjusting an amount. A reading should identify the meter, unit, value, date and source, distinguishing an actual measurement from an estimate or substitute value. Retain the rule version, its parameters, effective dates and approver; a later change must not alter the interpretation of a historical settlement.
