Quote: residential energy performance certificate
E.g.: mandatory EPC before putting a detached house up for sale
State the purpose: sale, letting, construction, extension or alterations. Provide any existing certificate, available plans and changes since issue. For an apartment, first check building records with the property manager before commissioning new work.
Check whether a certificate is required
Guichet describes sale, letting, construction and certain alterations, including exceptions. Check an existing valid CPE and the implications of changes. Stated validity is ten years, without removing the need to assess obligations arising from alterations.
Choose an authorised person and prepare the visit
The official page identifies OAI architects and consulting engineers and experts approved by the Ministry of the Economy. It provides for a visit to existing buildings. Prepare plans, known construction details, equipment and available consumption records; clarify how missing information is handled.
Distinguish the indicators
The CPE separates energy performance, thermal insulation and environmental performance. Calculated demand does not guarantee each occupant’s bill. Compare corresponding indicators and issue dates rather than a combined label such as AAA.
Plan documents for the intended purpose
Request the certificate and explanation for advertising, the notary or work application. For Klimabonus 2026 renovation with energy advice, the pre-renovation CPE is part of approval-in-principle documentation. The certificate alone does not establish grant eligibility.

On quotation
Fees depend on scope and the information to be surveyed. Request an offer defining building coverage, visit, data collection, calculation, delivered document and corrections. No local average price is established here; a CPE and a detailed renovation study are different services.
Subsidies and grants
No grant is deducted from the budget shown here. If a quote mentions support, request the exact scheme and confirmation of your eligibility before including it in financing.
Frequently asked questions
Is a new certificate needed for every sale?
First check the existing valid certificate, alterations, conditions and exceptions.
Does CPE predict my exact bill?
No. It describes calculated performance; usage and tariffs affect actual bills.
Does a poor rating make every suggested alteration mandatory?
Distinguish the certificate from project obligations. Request assessment of measures and applicable requirements.
Is certification never eligible for support?
Do not generalise. Check the exact service and applicable scheme without deducting unconfirmed amounts.
