Kyiv, September 23, 2025
LLC “MASTERGAZ” (EDRPOU code 38321792), a VAT payer (all prices on the website are indicated in UAH including VAT), represented by its authorized representatives, publicly offers to an indefinite circle of persons (hereinafter – the Buyer) to conclude a contract for the sale of goods and provision of services on the website mastergaz.com.ua under the following terms and conditions. This offer is a public contract (offer) in accordance with Art. 633 of the Civil Code of Ukraine, and in the case of acceptance (consent) of its terms, the Buyer undertakes to comply with the provisions of this Agreement.
General conditions: This Agreement enters into force from the moment of acceptance by the Buyer of this offer. Unconditional acceptance is the Buyer’s action indicating consent to the Agreement, namely clicking the “Confirm order” or “Pay” button on the order page of the Website and receiving an order confirmation from the Seller electronically (to the Buyer’s email or personal account). From that moment, the Agreement is deemed concluded. Before clicking the order confirmation button, the Buyer must check the box “I agree with the terms of the Public Offer and the Privacy Policy,” which confirms familiarity and consent to the Agreement. The Seller insists that prior to acceptance, the Buyer should carefully read this Public Offer and Privacy Policy. If the Buyer does not agree with any clause of the offer, they must refrain from placing an order for goods/services on the Website.
2.1. The subject of this Agreement is the paid provision by the Seller to the Buyer of Goods and/or Services offered on the Website, as well as the performance of necessary actions for their delivery or execution, under the terms and procedures defined herein. This public contract simultaneously covers both the sale of Goods and the provision of related or standalone Services.
2.2. Assortment and description of Goods and Services, their key characteristics, prices, and conditions of service provision are defined in the relevant sections of the Website (product catalog, service catalog). All offers for the sale of Goods and provision of Services posted on the Website are valid within the availability of the corresponding goods/service. The Seller may unilaterally update the assortment, prices, and other information on the Website.
2.3. Territory and service availability: The Seller carries out the sale and delivery of Goods throughout Ukraine (via postal carriers as described below). Provision of on-site Services is carried out within Kyiv city and nearby suburbs of Kyiv region (the area of operation of the Seller’s service specialists). The Seller does not provide services outside the defined area, of which the Buyer is informed during order placement.
2.4. Age restrictions: The Buyer under this Agreement may only be a person over 18 years old (for individuals). By placing an Order, the Buyer confirms compliance with this criterion. The Seller is not liable for the sale of goods/services to persons who provided false information about their age or legal capacity.
3.1. Order placement: The Buyer independently selects the required Goods and/or Services on the Website, forms an Order by adding the selected items to the “Cart.” On the checkout page, the Buyer fills in the required data: contact information, delivery address (if ordering Goods with delivery), selects the payment method, and confirms the Order.
3.2. Data verification: Before clicking the confirmation button, the Buyer has the opportunity to verify the correctness of the entered data and the content of the order. If errors are found or changes are needed, the Buyer can correct the order (change quantity, remove or add items, update contact data or address, etc.) directly on the checkout page. The Website provides tips for checking and correcting data before confirmation. The Buyer must not confirm the order until sure of the correctness and completeness of the information provided.
3.3. Confirmation and acceptance: After completing all required fields and choosing order parameters, the Buyer clicks the “Confirm order” (or similar, e.g., “Pay”) button. By doing so, the Buyer confirms consent to purchase the selected Goods/Services and accepts the terms of this Agreement (acceptance of the offer). The Agreement enters into force from the moment the Seller confirms the order. The Seller sends the Buyer an electronic confirmation of the order – in the form of an email to the specified address and/or a message in the personal account on the Website. The confirmation contains order details (list of goods/services, total amount, chosen payment and delivery options, etc.), which confirms the fact of contract conclusion.
3.4. Order rejection: The Seller reserves the right to refuse processing an Order if the information provided by the Buyer is incomplete, raises justified doubts, or if the Seller is unable to fulfill such an order (lack of goods in stock, lack of access to the service location, etc.). In case of impossibility to fulfill the order, the Seller informs the Buyer using the provided contact data to resolve the situation (replace goods, cancel the order, agree on new conditions, etc.).
4.1. Cost of goods and services: Prices for all Goods and Services are indicated on the Website in the national currency of Ukraine – hryvnia (UAH). All prices are final and include taxes, including VAT, unless otherwise explicitly stated. The Seller may change prices unilaterally, but such changes do not affect already confirmed Buyer’s orders (for them, the price valid at the moment of acceptance applies). In case of a pricing error for already ordered goods/services, the Seller immediately informs the Buyer for confirmation or cancellation.
4.2. Payment methods: The Buyer may choose a convenient payment method from those available on the Website:
- Online payment by bank card – through electronic payment systems integrated on the Website (payment services of banks or processing systems). Payment is made by entering the Buyer’s card details on a secure payment page. After a successful transaction, the order is considered paid.
- Non-cash settlement by invoice – for legal entities and individual entrepreneurs, payment by invoice is possible. To select this option, the Buyer provides the necessary details, the Seller issues an invoice, and the Buyer pays it through the bank. The order is executed after funds are credited to the Seller’s account.
- Payment upon receipt of service (offline) – in case of ordering an on-site Service, the Buyer may pay in cash to the technician after completion of work, or by card on-site through a mobile POS terminal or by scanning the QR code/payment link provided by the technician. Such payments are processed through a secure online payment gateway, so the Buyer’s financial data remain protected.
(Note: Specific payment services – LiqPay, Portmone, GercPay, etc. – may be used by the Seller, but are not listed in the Agreement text to allow flexibility.)
4.3. Prepayment and booking: As a rule, the Seller does not require prepayment for works/services – payment is made upon completion. The cost of the technician’s on-site visit is included in the service price and is not paid separately (no separate booking or prepayment required). Prepayment may only be required if specific, custom equipment or non-standard components (not in stock) are needed. In such a case, the Seller informs the Buyer about the necessity of a 100% prepayment for such equipment/components. Prepayment applies only to the cost of such special equipment and is not charged as an advance for works.
4.4. Payment confirmation (fiscal receipt): The Seller registers payment operations through RRO/PRRO when required by law. An electronic fiscal receipt for the paid amount will be sent to the Buyer via email or messenger (Viber/Telegram/SMS) after payment – automatically or upon request. A paper receipt on-site is generally not issued. The electronic receipt confirms the payment and can be used by the Buyer as proof of purchase.
5.1. Methods of receiving goods:
- If the Buyer ordered only Goods (without on-site installation/service), delivery is carried out by courier services. The Seller ships goods across Ukraine via trusted carriers such as Nova Poshta or Ukrposhta, at the Buyer’s choice. Delivery can be to a carrier’s office or directly to the Buyer’s address. Self-pickup from the Seller’s warehouse/office is also possible if available on the Website.
- If the Buyer ordered a “goods + service” package or a separate on-site Service requiring goods (e.g., installation with meter purchase, equipment replacement, repair with spare parts, etc.), the required goods/materials will be delivered by the technician during the visit. In this case, no separate delivery fee within Kyiv and suburbs applies, as delivery is part of the service.
5.2. Dispatch and execution terms: The Seller strives to dispatch ordered Goods as quickly as possible. Usually, shipment to the carrier is made within 1–2 business days after order confirmation and (if prepayment) receipt of funds. Delivery time depends on the chosen carrier and distance, usually 1–4 days across Ukraine. On-site Services (installation, verification, repair, etc.) are performed at the date and time agreed with the Buyer. When ordering a service, the Buyer agrees on a convenient time for the technician’s visit. Rescheduling or canceling a visit is possible without penalties – the Buyer must inform the Seller as soon as possible (preferably at least 24 hours in advance). The Seller may also reschedule in case of force majeure or unforeseen circumstances (with agreement on a new time convenient for the Buyer).
5.3. Delivery obligations: Upon receiving goods from the carrier, the Buyer must check the integrity of packaging and the goods themselves. In case of damage or discrepancies, the Buyer must notify the carrier (file a claim/act) and immediately contact the Seller for resolution. When receiving goods from the technician, the Buyer must inspect them before installation/service begins. The Seller is responsible for proper packaging and shipment, but cannot be liable for actions of third parties (the carrier) after the handover – within the limits set by law and the carriage contract.
5.4. Service execution: Services (installation, verification, repair, etc.) are performed by qualified specialists of the Seller at the agreed time. The Buyer must provide access to the equipment/devices and ensure safe working conditions (access to premises, communications, etc.). After providing the service, the technician issues an act of completed works or another confirming document (if applicable), as well as necessary product documents (warranty card, meter verification note, etc.).
6.1. Moment of ownership transfer: Ownership rights to the ordered Goods pass to the Buyer at the moment of actual transfer to the Buyer. Such transfer occurs: (a) upon receipt of the goods by the Buyer from the carrier’s representative (signing the waybill or receiving the parcel at the office means the goods are transferred), or (b) upon direct handover by the Seller’s technician to the Buyer at the service site.
6.2. Transfer of risk of accidental damage/destruction: The risks of accidental loss or damage of goods pass to the Buyer from the moment of transfer to the Buyer or their representative. When delivered by a postal carrier, the risk passes to the Buyer at the moment the goods are handed over to the carrier (as the carrier assumes responsibility for the shipment’s integrity before the Buyer under transport conditions). When delivered by a technician – the risk passes at the moment of handover to the Buyer at the site.
6.3. Ownership of service results: All material results created during the provision of services (installation components, installed devices, etc.) after completion and full payment pass into the Buyer’s ownership. Until transfer of the service results (signing the act of completed works or actual completion), they remain the Seller’s property.
7.1. Voluntary refusal of goods (proper quality): A Buyer who purchased Goods remotely (via the Website) has the right to terminate this Agreement in the part concerning sales, by refusing the received goods of proper quality within 14 days from receipt (excluding the day of receipt), without giving reasons, in accordance with the Law of Ukraine “On Consumer Protection.” To exercise this right, the Buyer must notify the Seller by any available channel (email, phone) and return the goods.
7.2. Return conditions: Goods of proper quality may be returned if unused, preserving their commercial appearance, consumer properties, seals, labels, and full completeness (packaging, accessories, documents, etc.). The Buyer is liable for any decrease in value resulting from use. Some categories cannot be returned under law, including: custom-made goods, perishable goods, disposable packaged goods once opened, and others under Art. 9 of the Law. Goods sold by the Seller not eligible for return include: devices showing signs of installation/use (e.g., installed meters, filters after water passage), as well as individually assembled orders of non-standard parts. The Seller will clarify upon Buyer’s request if goods fall under exceptions.
7.3. Refund procedure: In case of refusal of proper-quality goods, the Buyer must return them at their own expense (large goods – method agreed with Seller). Return shipping is borne by the Buyer unless due to obvious defect, damage caused by Seller, or mismatch with the order – in such cases, the Seller pays shipping. After receiving and checking returned goods, the Seller refunds the Buyer within 14 days (usually sooner) to the provided details. Refunds are made by the same method as payment, unless otherwise agreed.
7.4. Exchange of goods: If the Buyer wishes to exchange goods of proper quality (e.g., another model), this is done by returning the initial item (as above) and placing a new order. Direct replacement may be agreed within the same 14-day period. Shipping costs for exchange are borne by the Buyer (except in case of defect or Seller’s error).
7.5. Return of defective goods: If the received goods are defective or malfunction due to manufacturer/Seller fault, the Buyer may, within the warranty period, claim remedies under the Law (free repair, replacement, price reduction, or termination with refund). In such cases, delivery to the service center or Seller is covered by the Seller. Buyer’s steps: contact Seller with problem description and follow warranty/return instructions.
8.1. Right to refuse service: The Buyer may refuse ordered Services (made remotely via the Website) within 14 calendar days from acceptance (conclusion of the contract), if the service has not yet been fully performed. To exercise this right, the Buyer must notify the Seller in writing (email) or orally (phone) with mandatory subsequent written confirmation. The Seller ceases service provision upon receipt.
8.2. Settlements upon refusal: If at the time of refusal notice the service was partially provided, the Buyer must pay the Seller proportionally for the part rendered or resources used (materials). The parties may draw up an act or document confirming this. If the Buyer prepaid, the Seller refunds for the unperformed portion within 14 days (or sooner by agreement).
8.3. Loss of right to refuse: The Buyer loses the right to cancel if: (a) the service was fully provided by the Seller before the 14-day term, with the Buyer’s explicit consent (e.g., immediate service requested); or (b) the service is urgent repair/maintenance at the Buyer’s premises carried out immediately at their request (under Art. 13(3) of the Law “On Consumer Protection,” urgent paid repairs cannot be refused post-factum). Thus, if the Buyer ordered urgent technician visit and works were completed with consent – cancellation rights no longer apply.
8.4. Documentary confirmation: After service provision, the Seller may issue an act of completed works or other document. If the Buyer refuses before completion, the parties may sign an act of provided services/expenses up to termination date to record scope and settle accounts.
9.1. Goods warranty: All goods sold by the Seller are covered by manufacturer warranty or warranties under law. Terms and conditions are indicated in the warranty card or other accompanying documentation. The Seller provides the Buyer with all warranty documents (warranty card, commissioning marks, etc.) upon transfer/installation completion. Warranty claims: if defects appear during the warranty period, the Buyer may contact an authorized service center or the Seller for assistance. The Seller facilitates transfer to service, replacement, or refund if legally applicable. Warranty service is free for the Buyer upon presentation of a warranty card and proof of purchase (electronic/paper receipt, invoice, etc.).
9.2. Service warranty: The Seller guarantees proper quality and professional execution of installation, repair, and other works. Warranty period for works is 24 months from signing the act of completed works (or equivalent document). Within this term, if defects due to Seller’s fault appear (e.g., leakage, incorrect installation), the Seller must correct them at their own expense within reasonable time. Warranty does not cover defects caused by Buyer misuse, third-party interference, force majeure (flood, fire, etc.), or other reasons beyond Seller’s control.
9.3. Additional warranties: The Seller may provide extended warranties or service programs (e.g., subscription-based service) – under separately published terms or contracts. Such terms are communicated to the Buyer and supplement this Agreement if the Buyer joins the program.
10.1. Contact channels: Communication with the Seller is through Website-listed channels: phone numbers, email info@mastergaz.com.ua, online chat (if available), or feedback form. The Buyer may contact regarding goods, services, orders, warranty, etc.

The Seller considers the claim within 7 business days and informs the Buyer of the results.
11.3. Jurisdiction: If unresolved by negotiation, disputes shall be settled in court. Jurisdiction is determined under procedural law. As a general rule, disputes between a business and a consumer may be filed at the defendant’s registered address. If the Seller is the defendant, jurisdiction is set at the Seller’s location (Kyiv), unless mandatory consumer protection rules allow filing at the Buyer’s residence.
11.4. Consumer rights protection: The Buyer may also appeal to consumer protection authorities (State Service on Food Safety and Consumer Protection) or other authorized bodies if the Seller violates their rights. This Agreement does not limit the Buyer’s statutory rights.
12.1. Force majeure circumstances: Parties are released from liability for partial/complete non-performance of obligations if caused by force majeure. Force majeure means extraordinary/unavoidable circumstances beyond control making obligations impossible, including: war, hostilities, terrorism, riots; natural disasters (flood, fire, earthquake); emergencies (blockades, strikes, unrest); government acts (transport bans, quarantine, other prohibitions); and other circumstances beyond control.
12.2. Actions upon force majeure: The affected party must promptly (within 5 calendar days) notify the other party in writing and provide confirmation from a competent authority (Chamber of Commerce or other, if applicable).

After cessation, the affected party must immediately notify the other of resumption of obligations.
12.3. Impact of martial law: The parties recognize that martial law in Ukraine is also a force majeure event. The Seller will make efforts to fulfill orders even under martial law but is not liable for delays or non-performance directly caused by hostilities or threats to employees’ lives/health.
