Renovating an apartment is statistically one of the most common sources of consumer disputes in Poland: the crew disappears after the advance payment, deadlines get missed, and "minor corrections" drag on for months. Meanwhile, the law provides you with surprisingly strong tools – from 14 days to withdraw from a contract signed in your apartment, through warranty on the completed work, to the possibility of completing the renovation with another crew at the expense of the one that failed. This guide shows how to hire a contractor wisely (contract, deposit, schedule), what rights you have if something goes wrong, how much VAT should be on the invoice, what can be remodeled without a permit – and where to get free legal assistance.
Last verification: July 21, 2026. Informational material – not legal advice. In disputes involving large amounts, consult a lawyer or consumer advocate; case law in renovation matters can be case-specific.
In Brief
- Renovation for consumers is usually a contract for work – it is valid even if oral, but only a written contract with a schedule and cost estimate truly protects you.
- A contract signed in your apartment (or by phone/email) = a contract outside the entrepreneur's premises: you have 14 days to withdraw without giving a reason – and without instruction for up to 12 months and 14 days.
- If the crew is late or does shoddy work? You can withdraw even before the deadline (art. 635 CC) or after calling have corrections done by another crew at the contractor's cost (art. 636 CC).
- You are entitled to a warranty under the Civil Code for completed work – defects identified within 2 years, and according to established interpretation for real estate work even 5 years from acceptance.
- Fixed price is fixed: the contractor cannot raise the agreed fixed price, "because more work came up" (art. 632 CC).
- Renovation service in an apartment up to 150 m² = VAT 8% (with materials included in the service price); materials purchased separately – 23%.
- Demolition of load-bearing walls and interference with common areas require a project, building formalities, and community consent – "free-for-all" ends with supervision orders.
- Free assistance: municipal/county consumer advocate and consumer hotline.
Before You Sign: Choosing a Crew and Contract
- Check the Contractor
CEIDG/KRS (whether the company exists and for how long), reviews from multiple sources, photos of completed projects, references with contact information. Ask about liability insurance – flooding a neighbor due to the crew's fault is your problem if the contractor lacks insurance and assets.
- Written Contract – with Details
Scope of work (preferably an attachment with a line-by-line cost estimate), materials (who buys, what class), stage deadlines, remuneration (fixed price or cost estimate – see below), payment schedule by stages, contractual penalties for delays, method of reporting defects. An oral contract is also binding, but in a dispute, one word stands against another.
- Deposit, not "advance payment in the dark"
A deposit (art. 394 CC) disciplines both parties: if the crew breaks the contract – you demand double the deposit; an advance payment simply gets returned. Do not pay more than 10–20% upfront; subsequent payments only after completed stages.
- Fixed Price or Cost Estimate?
Fixed Price: a fixed amount – the contractor cannot demand an increase, even if there is more work than anticipated (art. 632 § 1 CC; only a court, exceptionally, in case of gross loss). Cost Estimate: flexible, but keep an eye on items and unit prices – increases during work are only possible within legal limits (art. 630 CC).
- Protocols and Photos
Protocol of apartment handover (meter readings, existing defects), acceptance protocols for stages, before/after photos. This documentation wins disputes.
Did They Sign the Contract at Your Home? You Have 14 Days to Withdraw
A contract concluded outside the entrepreneur's premises (the contractor signs it at your apartment) or remotely (by phone, email) is subject to the Consumer Rights Act (t.j. Dz.U. 2024 poz. 1796):
- 14 days to withdraw without giving a reason (art. 27 sec. 1) – a statement is sufficient, e.g., on a form that the entrepreneur is obliged to provide you.
- 30 days if the contract was concluded during an unscheduled visit by the entrepreneur to your home or during a tour (art. 27 sec. 2) – a classic scenario of "professionals" going door-to-door.
- Were you not informed about the right to withdraw? The right expires only after 12 months from the original deadline (art. 29) – so you actually have over a year.
- Exceptions (art. 38): you cannot withdraw from urgent repairs or maintenance for which you called the professional – but only to the extent you requested (additional "while you're at it" services and goods – withdrawal applies!); nor from a service fully performed if you previously explicitly agreed to it knowing you would lose the right; nor from items made to your specifications (e.g., custom furniture). Importantly: during an unscheduled home visit, most of these exceptions do not apply at all (art. 38 sec. 2).
- Did work start before the deadline at your explicit request? Upon withdrawal, you pay proportionately for the completed part (art. 35) – not the whole amount.
The Crew Fails: Your Arsenal from the Civil Code
| Problem | Your Right | Basis |
|---|---|---|
| Delay so significant that the deadline cannot be met | withdrawal from the contract even before the final deadline, without setting an additional deadline | art. 635 CC |
| Work performed defectively or not according to the contract | call for a change in execution with a deadline; after its expiration – withdrawal or entrusting corrections/completion to another crew at the contractor's cost and risk | art. 636 § 1 CC |
| Fixed price "grows during" | you can refuse – fixed price cannot be increased | art. 632 § 1 CC |
| Defects appeared after acceptance | warranty: demand repair, price reduction, and in case of a significant defect – withdrawal | art. 638 in conjunction with art. 556+ CC |
| Contract termination by the contractor after the deposit | demand return of the deposit in double amount | art. 394 CC |
Claims from a contract for work expire after 2 years from the handover of the work (and if not handed over – from the day it was supposed to be handed over) – art. 646 CC. Do not postpone disputes.
Warranty for Renovation Defects
- Which regime? Renovation is a service whose effect is not a movable item – therefore, warranty from the Civil Code applies (art. 638 § 1 in conjunction with art. 556 et seq.). The consumer regime of "non-conformity of goods with the contract" from the Consumer Rights Act only applies to works that are goods (art. 43a) – e.g., custom furniture from a carpenter (there: first repair/replacement, liability for 2 years).
- Deadlines: the contractor is liable for defects identified within 2 years from the acceptance of the work, and according to established interpretation for real estate work – 5 years (art. 568 § 1 refers to "defects in real estate"). After identifying a defect, you have at least a year to pursue claims – and as a consumer, at least until the end of the entire warranty period.
- What can you demand: removal of the defect (repair), price reduction, or – in case of a significant defect – withdraw from the contract (withdrawal is not available for non-significant defects, art. 560 § 4). The contractor can once "preempt" a reduction/withdrawal by promptly removing the defect – for subsequent defects, this counter-right expires.
- Exclusion: the contractor is not liable for defects arising from a cause inherent in materials you provided (art. 638 § 1 sentence 2) – by purchasing "your" tiles, you take on their quality.
- Guarantee is a voluntary addition (document from the contractor/manufacturer) – it never limits the warranty.
VAT on the Invoice: 8% or 23%?
- Renovation service (renovation, modernization, thermal modernization, reconstruction) in a residential unit up to 150 m² or a house up to 300 m² = VAT 8% (art. 41 sec. 12 of the VAT Act in conjunction with art. 146ef) – even when the contractor includes materials in the service price (comprehensive service, established interpretative practice).
- Materials purchased independently at a store = 23%.
- Practical conclusion: it is often more beneficial to arrange the service "with materials" – the VAT difference can be greater than the contractor's margin on materials.
- An invoice/receipt is also your proof in a dispute and when claiming warranty – "cheaper without an invoice" means no record of the transaction.
- There is no general "renovation relief" in PIT (abolished years ago), nor is there a VAT refund for materials.
Subsidies and Reliefs for Renovation – What Works in 2026
| Instrument | For Whom | How Much |
|---|---|---|
| Thermal modernization relief (art. 26h of the PIT Act) | owners and co-owners of single-family homes (apartments in blocks – NO) | deduction from income up to 53,000 PLN per taxpayer (spouses – 53,000 PLN each); project completed within 3 years; invoices from VAT payers |
| Clean Air | owners of single-family homes (min. 3 years of ownership), three income thresholds (from 135,000 PLN per year down) | grant up to 170,100 PLN for comprehensive thermal modernization at the highest level; open recruitment (launch from 31.03.2025, changes from 20.07.2026); pre-financing by operators; hotline 22 340 40 80 |
- Note changes to the relief list from 1.01.2025 (Dz.U. 2024 poz. 1943): gas and oil boilers have been removed from the list; added, among others, energy and heat storage systems, energy management systems, and heat nodes. Gas boilers are also not subsidized by Clean Air.
- You cannot deduct the same expense twice (the relief does not cover the part financed by the grant).
- For a regular apartment renovation in a block, mainly VAT 8% on the service remains – there is no general renovation relief or VAT refund for materials.
What Can Be Renovated Without a Permit – and What Requires Formalities
| Work | Formalities |
|---|---|
| Painting, smoothing, flooring, replacement of white goods, furniture, internal doors | none – ongoing maintenance |
| Renovation of the unit (restoring the state, even with newer materials) and installations – except gas | none (art. 29 sec. 4 point 2 letter a and point 3 letter d of the Building Law) |
| Reconstruction within the unit without affecting structural elements and external partitions (e.g., moving a partition wall) | none (art. 29 sec. 4 point 1 letter a) – but first, a constructor must confirm that the wall is not load-bearing |
| Gas installation (installation, reconstruction) | notification (art. 29 sec. 3 point 3 letter d) + performed by a qualified person and a tightness test |
| Interference with load-bearing walls / structural elements / external partitions in a block | building permit + project (outside the exemption catalog from art. 29) and community consent |
- Common parts of the building (load-bearing walls, facade, installation risers, partitions between units, usually also balconies): interference requires community consent (resolution – this is an action exceeding ordinary management; art. 22 of the Act on Ownership of Premises) or cooperative consent. In practice, the manager will also ask for a project and a constructor's opinion.
- Working hours: there is no nationwide law – the regulations of the community/cooperative apply; persistent disturbance of peace is an offense (art. 51 of the Offenses Code). Post a notice with apologies and the end date of work – it works better than a war with neighbors.
Remote Renovation – for the Polish Diaspora
- Trusted person or inspector for stage acceptance – payments only after the acceptance protocol (photos + video).
- Contracts and annexes signed electronically or by proxy; plan foreign transfers with a buffer (AML).
- A camera in the apartment during the renovation – legal in your premises, but inform the crew (GDPR/personal rights).
- Collect invoices and receipts immediately in the cloud – they will be useful for warranty claims and future sales.
Common Mistakes
- Large "advance payment" upfront without a contract – a classic of disappearances; deposit + payments by stages.
- Oral contract "on trust" – without scope and deadlines, you have nothing to enforce.
- Full payment before defects are removed – hold back 10–15% until final acceptance.
- Lack of written notice – rights from art. 635/636 CC are activated by formal writing (email/SMS is also a record), not by a quarrel.
- Missed 14 days to withdraw from a contract concluded at home – or ignorance that lack of instruction extends it by a year.
- Demolishing a wall "because the manager from YouTube said it was a partition" – without a constructor and formalities, you risk supervision orders and liability to neighbors.
- "Cheaper without an invoice" – you save 8% VAT, lose all evidence.
- Postponing a dispute – the 2-year limitation period from art. 646 CC runs faster than you think.
Frequently Asked Questions
I signed a contract with a contractor at my home and regret it. What can I do?
Withdraw without giving a reason: within 14 days, and if the visit was unscheduled – within 30 days. Without instruction about this right, the deadline effectively extends to over a year. Send a statement (email is sufficient, but a registered letter is better proof). If work has already started at your explicit request, you will only pay for the completed part.
The crew took an advance and is not answering the phone. What to do?
Written request to start work with a deadline (e.g., 7 days) and a notice of withdrawal; after expiration – withdrawal in writing and request for a refund (for a deposit – double). Then: consumer advocate, lawsuit (for amounts up to 4,000 PLN, the court fee is only 30 PLN in simplified proceedings), possibly report fraud if the company "serially" disappears after advances.
After six months from the renovation, tiles are coming off. Can I demand a repair?
Yes – under warranty. Report the defect in writing and set a deadline for repair; if there is no response, you can demand a price reduction, withdraw (in case of a significant defect), or have another company repair it and claim costs. Deadlines work in your favor: liability for defects identified within 2 years (for real estate work – according to established interpretation 5 years), and as a consumer, you have time at least until the end of this period for claims. One "but": if you bought the tiles yourself and they are defective – the contractor is not responsible for your material.
The contractor demands an additional payment for the fixed price halfway through the work. Do I have to pay?
No – the fixed remuneration cannot be increased, even if there is more work than expected (art. 632 § 1 CC). The only exception is a court change in case of gross loss to the contractor due to unforeseen changes in circumstances. You can calmly refuse additional payments "because of inflation".
Can I demolish a partition wall without notification?
A wall that is actually non-load-bearing within your own unit – yes, without a permit and notification (this is a reconstruction not affecting structural elements, art. 29 sec. 4 point 1 letter a of the Building Law). But: leave the assessment of "load-bearing or partition" to a constructor (not to plans from the internet), and check the regulations in the cooperative/community – notification to the manager may be required. A load-bearing wall is a completely different league: project, permit, community consent.
Where can I get free help in a dispute with a contractor?
Municipal/county consumer advocate (free advice, may even file a lawsuit on your behalf – art. 39–42 of the Competition and Consumer Protection Act; search engine at uokik.gov.pl), consumer hotline 801 440 220 / 22 266 76 76 (weekdays 10:00–18:00, commissioned by UOKiK), e-advice at dlakonsumentow.pl and permanent arbitration courts at provincial inspectorates of the Trade Inspection. For amounts up to 4,000 PLN, the lawsuit fee is only 30 PLN.
Fact-Check Summary
Definitely true (verified in consolidated texts: CC – Dz.U. 2025 poz. 1071, Consumer Rights Act – Dz.U. 2024 poz. 1796, VAT – Dz.U. 2025 poz. 775, PIT – Dz.U. 2026 poz. 592 with regulation Dz.U. 2025 poz. 1128 after amendment Dz.U. 2024 poz. 1943, Building Law – Dz.U. 2026 poz. 524, Act on Ownership of Premises – Dz.U. 2026 poz. 232, Competition and Consumer Protection Act – Dz.U. 2025 poz. 1714, and on czystepowietrze.gov.pl and uokik.gov.pl): withdrawal before the deadline (art. 635 CC) and substitute performance at the contractor's cost and risk (art. 636); fixed price without increases (art. 632); limitation period of 2 years (art. 646); double deposit (art. 394); warranty CC for renovation services (art. 638 → 556 et seq.; goods regime only for works that are goods – art. 43a of the consumer act), deadlines of 2/5 years (art. 568 § 1), prohibition of withdrawal for non-significant defects (art. 560 § 4), exclusion for materials ordered by the customer; consumer withdrawal 14 days / 30 for unscheduled visits, expiration after 12 months from the deadline, exception for urgent repairs only in the requested scope and exclusion of exceptions for unscheduled visits (art. 27, 29, 38 CPR), payment for part when service has started (art. 35); VAT 8% on renovation/modernization up to 150/300 m² (art. 41 sec. 12 and 146ef of the VAT Act); thermal modernization relief of 53,000 PLN only for single-family homes, without gas boilers from 2025; Clean Air – open recruitment, grants up to 170,100 PLN; renovation of the unit and installations (except gas) without formalities, gas installation requires notification, construction = permit (art. 29 PB); community consent for reconstruction of common parts (art. 22 of the Act on Ownership of Premises); consumer advocate and hotline 801 440 220 / 22 266 76 76.
Probably true (established practice/jurisprudence): 5-year warranty period for work permanently associated with real estate; VAT 8% on the service "with materials" as a comprehensive service; balcony as common part; regulatory working hours and nighttime quiet hours 22–6.
What is uncertain/individual: qualification of specific works (work vs construction work), boundaries of "significant defect", local regulations of communities.
Common myth: "oral contracts do not count" (they bind – only harder to prove) and "once I paid, I can do nothing" (warranty and art. 636 CC work after payment).
