What we compare
We compare pellet offers from selected shops and other supported sources. The comparison does not cover the entire market. An offer may be absent because its source is missing, data is outdated or ambiguous, delivery is restricted or filters exclude it. Catalogue inclusion is not a seller recommendation.
The starting point is your requested quantity, 975 kg by default. We account for whole available packages and purchase conditions. For example, two 600 kg pallets mean purchasing 1,200 kg even if you need 1,000 kg. The per-tonne cost uses 1,200 kg. Prices and costs are gross PLN; displayed rounding does not alter the calculation basis.
Main ranking parameters
First we select offers matching your request and filters, such as quantity, product, packaging, parameters, collection method and delivery location. We then group recognised variants of the same product. A group's result shows the offer best matching the selected sort; opening the group lets you compare the other sellers. Unrecognised offers may remain separate results.
| Comparison | Main ordering factor |
|---|---|
| Delivered price per tonne | Calculated goods and delivery cost divided by the mass actually purchased, subject to the labelled assumptions below |
| Goods price per tonne | Pellet cost alone divided by the mass actually purchased |
| Purchase cost | Total for the selected packages, including delivery when determined, or excluding delivery in the relevant context |
Lower costs appear first by default. You can reverse the sort direction. For comparable results with equal amounts, a more recent offer observation comes first; further ties use a stable order of offer and package identifiers. Identifiers are not quality scores. Price is the main criterion; freshness is a secondary tie-breaker.
Offers with unknown, individually quoted or ineligible delivery do not compete with calculated delivered prices. A separate tab lets you compare goods-only prices; ties there use stable offer and package ordering. Its first result is not necessarily the cheapest delivered purchase.
Delivery: facts and assumptions
A postcode helps filter the delivery area; it does not establish an exact address or road distance. When coverage is unknown, we may use a search assumption of a 50 km radius from the known seller locality or point. This approximate straight-line distance is an offer-discovery filter, not a delivery promise or price.
The service assumes a labelled free-delivery zone within 20 km of a known delivery center, even without an explicit seller free-delivery statement. This estimate may affect delivered-price comparisons and requires seller confirmation. Explicit local delivery charges, area restrictions and order conditions take precedence. A separate nationwide courier service remains available outside the assumed zone.
For a source with confirmed nationwide coverage and a matching purchase variant, delivery may be estimated from a sample of at least ten locations. Without a postcode, the highest sampled amount is used. With a complete sample map and a postcode, the service may use that postcode's amount, a sufficiently nearby point or the highest amount, as labelled with the result. This estimate may enter the ranking; it is not individual confirmation of a seller's tariff. Entering a delivery location may change eligibility and ordering.
When one package's delivery cost is known, multiplying it for several packages may be only an indicative estimate if the seller requires an individual quote for larger orders. This estimate is excluded from delivered-price rankings. Confirm unloading, payment, access and quantity conditions at the source.
Listings, mass and uncertainty
For some listings, pallet mass may be estimated at 975 kg when the source does not state it and comparison rules permit this calculation. We label the estimated mass and resulting purchase. It is not a measurement or seller assurance. A different actual mass changes the comparison.
A package price derived from a per-tonne price is a calculation. For certain listings with a bounded price range for product variants, calculations may use the upper end where a lower price cannot be assigned. This does not confirm a particular transaction price. Material assumptions are explained beside the price.
A seller may change an offer after we read it. The catalogue is not a guaranteed real-time measurement. Notices about outdated information and unresolved conditions take precedence over an attractive amount.
Quality and statistics
The specification assessment is an editorial comparison of available declared parameters, not a pellet test or an assessment of seller honesty. A missing parameter does not prove poor quality. The assessment does not improve price-ranking position. A seller-listed certificate remains their claim unless a specific verification is expressly described.
Statistics describe observed offers, not every transaction in Poland. Changes in sources, mass, delivery method and available data can affect results. Energy-cost comparisons depend on stated parameters and assumptions; they do not guarantee the heating cost of a particular building. Historical statistics are not automatically the lowest 30-day price required when announcing a discount.
Funding and advertising
At launch, the service earns no advertising, affiliate or paid-position revenue. Sellers do not pay for a higher comparison position.
