The consumer advice centre advises project owners on contract law, consumer rights and general construction questions. We review construction quotes specifically for price fairness, completeness and variation risks. Both services have real strengths, but they address different starting points.1
Key points at a glance
- The consumer advice centre provides legal advice on contracts and defect claims — cost: 180–370 €/hour, waiting time: 1–3 weeks
- Cleverbauen24 analyses price fairness, missing items and variation risks — providing a written review report within 24 hours to 4 working days
- The consumer advice centre does not provide market price comparisons or systematic completeness checks — these require a specialist quote review
What does the consumer advice centre offer?
Consumer advice centres are non-profit institutions that advise consumers on legal matters. They receive partial funding from the federal and state governments and operate independently of commercial interests.4 In building and housing, advice focuses on legal aspects: construction contracts, consumer rights in dealings with contractors and businesses, and disputes after work is completed.
Types of advice
Consumer advice centres offer construction advice in three formats: by telephone (brief initial advice), in person at an advice centre (1 to 2 hours, by appointment), and in writing (reviewing draft contracts or documents by email or post).1
Topics
The consumer advice centre's main construction advice topics include:
- Construction contracts and contract clauses (BGB and VOB/B)5
- Consumer rights concerning defects and defect liability
- Energy advice and funding programmes
- Disputes with tradespeople and construction companies
- General questions about planning, financing and construction law
Prices and waiting times
One hour of advice at the consumer advice centre costs between 180 and 370 euros, depending on the federal state and format. Individual initial telephone consultations may cost less. As capacity is limited, waiting times for appointments are generally 1 to 3 weeks.1
Limitations
The consumer advice centre's construction advice is primarily legal and general in nature. Analysing individual quote items, comparing regional market prices or systematically checking the completeness of a bill of quantities are not part of the standard service. Advice is often given verbally and generally does not include a written review report.2
What does Cleverbauen24 offer?
Cleverbauen24 is a digital review service for trade and construction quotes. It focuses on analysing the content and pricing of an existing quote before the project owner signs.
Process
You upload the construction quote as a PDF. We analyse the document through a combined process of AI-assisted analysis and manual expert review. The result is a written PDF report with specific findings, risks and recommendations.
7 review categories
The review covers seven areas:
- Price fairness: Comparing individual items with regional market prices
- Completeness: Are all reasonably expected work items included?
- Variation risks: Which wording or omissions could lead to additional claims?
- Quantity and arithmetic checks: Are quantities and pricing items correct?
- Contract clauses: Are there unfavourable terms on payment deadlines, defect liability or liability?
- Specification: Are work and materials described in sufficient detail?
- Formal observations: Legally required information, missing documents, formal shortcomings
Free Quickcheck
If you would first like an initial assessment, you can submit your quote free of charge through the Quickcheck. The Quickcheck gives an instant AI-assisted assessment without a full review report. The detailed report with recommendations is available from 79 euros.

Conclusion: The consumer advice centre has a clear advantage on legal questions and consumer rights. The Federal Ministry for Housing, Urban Development and Building (BMWSB) recommends that private project owners seek both legal and financial advice before signing a contract.6 Cleverbauen24 specialises in analysing the quote's content and pricing. If you need both, you can combine the services.
When is the consumer advice centre the better choice?
The consumer advice centre has clear strengths on legal questions. It is the right place to turn when:
- You want to resolve an ongoing dispute with a tradesperson or construction company
- You have questions about consumer rights beyond the specific quote
- Your review budget is below 100 euros and you want initial guidance
- You prefer a personal consultation and have enough time
- You need energy advice, information about funding programmes or answers to fundamental construction law questions
As a non-profit institution, the consumer advice centre is also suitable when you have no specific quotes and need general information. The Verband Privater Bauherren (VPB) points out that around 75 per cent of all private residential construction contracts contain clauses that could be improved.7 If you want to know more about your legal position in relation to a contractor, the consumer advice centre is a good choice.
When is Cleverbauen24 the better choice?
Cleverbauen24 specialises in reviewing specific quotes and is useful when:
- You want to assess an existing quote before signing
- You want to know whether individual prices are in line with the market
- You are short of time and need a result within 24 hours
- You want a written report you can show the contractor
- You want specific recommendations for renegotiation
- The quote exceeds 15,000 euros and a completeness check would be worthwhile
Because the review report records all findings in writing, you can use the result directly as the basis for a discussion with the contractor. Our guide explains what this looks like in practice: Negotiating a contractor's quote.

There are several ways to have a construction quote or contract reviewed. The following table provides an overview of the usual options, with costs and turnaround times:3
| Provider | Cost | Time |
|---|---|---|
| Surveyor | 360 – 714 € | 2 – 4 weeks |

| Cleverbauen24 | from 79 € | 3 – 4 days (Basic) / 24 hours (Express) |
The choice depends on what needs reviewing. For purely legal questions, the consumer advice centre or VPB is suitable. For analysing a quote's content and pricing before awarding a contract, we offer the fastest and most affordable option. A complete overview of the review options is available in our Guide: reviewing a construction quote.

Frequently asked questions
What does construction advice from the consumer advice centre cost?
Construction advice from the consumer advice centre costs between 180 and 370 euros per hour, depending on the federal state and consultation format. Initial telephone consultations are cheaper in some states. Exact prices vary regionally and are set by the relevant state consumer advice centre.1
Does the consumer advice centre review contractors' quotes?
Not systematically. The consumer advice centre can look at contract documents and quotes during a consultation, but generally does not provide an item-by-item review with market price comparison. If you want a complete quote review with a written report, a specialist provider such as Cleverbauen24 is a better choice.
How long does construction advice from the consumer advice centre take?
The waiting time for a consultation is generally 1 to 3 weeks. The consultation itself takes 30 to 90 minutes, depending on the format. Written reviews may take several working days, depending on the work involved.1
What is the difference between the consumer advice centre and a quote review?
The consumer advice centre advises on consumer rights and legal questions concerning construction contracts. A specialist quote review such as Cleverbauen24 analyses the specific quote for price fairness, completeness and variation risks, and provides a written report with recommendations. The services complement each other but only partly overlap. Read more about the difference between a cost estimate and a quote in our Guide: cost estimate vs quote.
Can the consumer advice centre assess prices in a construction quote?
Not systematically. The consumer advice centre does not have access to regional market price databases and generally assesses quotes legally rather than analysing their cost calculations. According to the Federal Statistical Office (Destatis), residential building construction prices rose by around 55 per cent between 2015 and 2025, making it difficult to assess quoted prices without current market data.8 We provide an item-level market price comparison. Our guide explains exactly what should be checked when assessing a construction quote: Guide: reviewing a construction quote.

Comments
The consumer advice centre helped me resolve a dispute with my electrician back then. Good and inexpensive — but it really is not enough for complex quotes.
I have experienced waiting 3–6 weeks at the consumer advice centre myself. By then, you have long since accepted or rejected the quote.
How exactly does the advice process at the consumer advice centre work — do you always have to attend in person?
That depends on the regional organisation. Many consumer advice centres now offer telephone and video consultations too. Construction advice often requires an in-person discussion, though, because advisers want to see the documents. I recommend booking online beforehand and asking what to bring.
An objective comparison without self-promotion. Thank you.
