Essential for any property sale, mandatory technical diagnostics represent a significant expense. With increased certification requirements for diagnosticians since July 2024, driven by the new DPE, prices have seen noticeable inflation. At Consultants Immobilier, experts in high-end property appraisal and sales in Paris, we help clarify this aspect. Discover our advice to assess the fair price of your diagnostics and optimize this budget without compromising the quality of your sales file.
Tangible inflation since the 2024 reform
The strengthening of professional certifications effective from July 1, 2024, has led to a noticeable rise in real estate diagnostic prices. On average, prices have increased by 10 to 15%, with peaks of 20% for more technical services like DPE or asbestos diagnostics.
This inflation is due to stricter initial and ongoing training requirements for diagnosticians. For a DPE with mention, total training duration now reaches 77 hours, including substantial on-site practice. This upgrade in qualifications, essential to ensure reliable energy audits, represents an average investment of €5,000 per year per professional. This financial burden inevitably impacts the rates charged to individuals.
For a 50 m² Parisian apartment, the average cost of an essential pack (new DPE, asbestos, lead, Carrez law, ERP, electricity) increased from €600-700 in 2023 to €700-800 in 2024, a rise of around 15%. The impact is even more pronounced for older homes in the regions, with costs soaring from €1,000 to €1,200, a tangible inflation of €150 to €200.
This upward trend is expected to continue in the coming years as new certification standards take effect. Newly trained diagnosticians will gradually pass on the cost of their upgrades to their services. By 2025-2026, an overall price increase of 20 to 25% from 2023 levels is anticipated.
Rates vary according to multiple factors
The cost of a real estate diagnostic depends on several key factors:
Type of expertise
An asbestos diagnostic, requiring samples and extensive analysis, will cost between €100 and €200 on average, compared to €20 to €30 for a Risk and Pollution Report (ERP). The DPE, now enforceable, ranges from €100 to €250.
Property size and configuration
Expect about €150 for a DPE on a 20 m² Parisian studio, but closer to €250 for a family house of 150 m² in the provinces. The cost of the Carrez law diagnostic, required in condominiums, also varies from €100 to €150 depending on the type of lot (studio, duplex, converted attic, etc.).
Year of construction
An older property will require more thorough investigations, such as the lead exposure report mandatory for any property built before 1949 (average cost €150). For a 1930s house with outbuildings, the total diagnostics budget will be closer to €1,000.
Geographical location
For equal services, prices can vary by 20 to 30% between Île-de-France and other regions due to the cost of living and the concentration of certified professionals. In Paris, the base price of an “essential” pack (DPE, asbestos, lead, Carrez law, ERP, electricity) is around €700-800.
Additional included services
A pack including digital dossier layout, personalized oral report, or dedicated hotline will generally be more expensive. However, it can save you precious time and facilitate information sharing with your notary and potential buyers.
Reputation of the diagnostician
An experienced expert or a well-known diagnostician will charge higher rates (up to +20%) than a beginner independent diagnostician. But their experience will ensure particularly thorough reports for unique properties (castles, historic monuments, etc.).
How to get the right price? Our recommendations
To optimize your diagnostics costs without sacrificing quality, here is our expert advice:
- Anticipate diagnostics ahead of your property valuation: this allows you to negotiate prices and refine your financing plan.
- Shop around by requesting quotes from at least 3 certified professionals.
- Opt for a reputable and experienced provider: even if slightly more expensive, their comprehensive diagnostics will secure your transaction and reassure buyers.
- Review included services: an attractive price may lack essential services (hotline, 24-hour report).
- Only order necessary diagnostics: no need to request a termite report if your building is certified termite-free! A good diagnostician will advise you.
- Choose a comprehensive pack instead of individual diagnostics: the overall cost will be more advantageous.
- Use your network: your real estate agent, property manager, or notary can direct you to competitive and reliable professionals.
- Look for possible local subsidies: some municipalities offer targeted assistance, such as “eco-energy” vouchers to fund an audit.
In sum, more than just the price criterion, it is the quality-reliability-comprehensiveness ratio that should guide your choice. Only a complete and flawless technical diagnostic file will be a decisive asset to enhance your property and attract potential buyers. This is especially important in highly competitive markets such as real estate listings in Paris.
The experts at Consultants Immobilier are available to guide you to the best specialists, able to create a customized file closely aligned with your budgetary constraints. We know that a quality diagnostic is the cornerstone of a smooth and successful sale!
