Best Demand Certificate Providers 2026: Portals Compared
You want to have a demand certificate issued — now you need the portal that captures your photos and facade dimensions smoothly and still issues a compliant certificate. This short comparison covers three established providers for 2026, with emphasis on quality, mobile capture, customer feedback and portal ratings (ProvenExpert, Trustpilot, Google).

Who this short comparison is intended for
If you still need to check whether a demand certificate (Bedarfsausweis) is required — or whether the consumption certificate (Verbrauchsausweis) remains the cheaper option — start with the certificate check. If you want to have a demand certificate issued, the demand certificate provider review provides the seven-point checklist, tables and legal-safety criteria. This Best-of short comparison adds a shortlist for a quick choice, including customer feedback and ProvenExpert ratings (plus Trustpilot and Google signals for the other portals).
From 2027 the consumption certificate will be choosable more often for pure residential buildings. Nevertheless, the demand certificate still makes sense when the energy ratings should reflect the building condition. You will find background in the articles Order a demand certificate online and Consumption certificate providers 2026.
Five criteria for demand certificate portals 2026
Before we present the results of our short comparison, it is worth looking at our key criteria:
| Criterion | Why it matters |
|---|---|
| Issuer under § 88 GEG + DIBt number | Without a qualified person and registration number, the PDF certificate is ineffective |
| Calculation under DIN V 18599 | The demand certificate reflects envelope and plant — not just your heating behaviour |
| Easy capture including mobile | Photos of facade, heating system and nameplate reduce follow-up questions and delays |
| Personal plausibility check | Contradictions (year built vs. U-value) must be caught before issue |
| Traceable customer feedback | Real experiences on forms, turnaround and support complement the checklist |
A more detailed criteria list is in the review article. A compliant certificate and straightforward data capture matter more than the lowest price. If photos are missing or your details do not add up, then lengthy follow-up questions can delay issuance — whichever portal you choose.
Shortlist — Best demand certificate providers 2026
The table below shows three portals that offer demand certificates for residential buildings nationwide and met minimum standards in our earlier tests (imprint, terms, seat in Germany).
| Portal | Demand certificate (residential) | Mobile & photos | Review signal (Oct 2026) |
|---|---|---|---|
| energyausweis.de | €99 fixed price | Smartphone/tablet, fast upload | ProvenExpert 4.9 · 69 ratings |
| mcenergieausweis.de | €99 | Form usable on phone | Trustpilot approx. 4.7 · 177 ratings |
| online-energieausweis.org | from €115 | Form; phone follow-up | Google approx. 4.9 · 112 reviews |
energyausweis.de — Quality, mobile and customer reviews
energyausweis.de offers the residential demand certificate at a fixed price of €99. The interface is built for smartphone, tablet and desktop; you capture photos and dimensions on your phone on the go or on desktop before a certified energy adviser reviews your entries. Quality-seal software and personal plausibility checks are part of the process. For methodology details, see the review article.
Customer feedback (ProvenExpert, excerpts): The Kundenstimmen page shows 4.9 out of 5 stars from 69 ratings (October 2026; latest published on ProvenExpert 15 Oct 2026). Below is a selection of verbatim excerpts from published reviews:
It was very easy to get the certificate, everything well explained, quick upload and the result was in my inbox the next day. — Thomas P., 24 Sep 2026
Filling in the required information was very easy and clear. After submitting the data the certificate arrived within minutes — can’t get faster. — Jakob K., 2 Sep 2026
My certificate was corrected free of charge within 24 hours because my details were wrong. Great service!! — Oliver L., 15 Oct 2026
When quality, tight deadlines or mobile capture matter, energyausweis.de is our first pick in this shortlist. Data capture is also highly structured. Read the article Order a demand certificate online beforehand to learn about the order process.
mcenergieausweis.de — Price and ratings
mcenergieausweis.de also prices the demand certificate at €99. Data capture works on mobile but felt less comfortable than energyausweis.de in our comparison; express delivery is available for a surcharge. Quality messaging is very restrained: neither quality-seal software nor explicit adviser review is addressed.
Customer feedback (Trustpilot, excerpts): Publicly about 4.7 out of 5 from 177 ratings (October 2026; research on Trustpilot). Trustpilot notes that review invitations can skew distribution. We quote only published reviews verbatim; after 10 Mar 2026 our sample showed no further dated Trustpilot quotes — so two texts from 10 Feb 2026 and 10 Mar 2026 (fewer new ratings than ProvenExpert for energyausweis.de).
Entering the data is relatively easy and well explained. After answering a follow-up question it took just 12 minutes until I received the certificate. — Trustpilot review, 10 Feb 2026
I was totally surprised how uncomplicated the application was. Follow-up questions were answered immediately. Simply great! — Trustpilot review, 10 Mar 2026
One review explicitly mentions a demand certificate for selling a detached house — a typical scenario this guide is written for.
online-energieausweis.org — Engineer review and reviews
At online-energieausweis.org (Cornelsen engineering office, Hamburg) residential demand certificates are offered from €115 (provider figure, research September 2026). Phone follow-up is part of the offer here too, as at energyausweis.de; capture on mobile is possible and the interface is solid. The focus is personal engineer review — the provider does not highlight quality-seal software.
Customer feedback (Google, excerpts): The provider cites 4.9 out of 5 from 112 Google reviews (16 Sep 2026). We quote only published Google reviews verbatim. In October 2026 research, 24 Feb 2026 was the latest dated quote we could verify; we could not find current review text — so only this one quote:
Competent advice. Easy to reach by phone for questions; calls back promptly if needed. Always happy to recommend them for energy certificates! — Google review, 24 Feb 2026
On Trustpilot there are only few entries (3.3 stars, three ratings; latest April 2025) — we could not find current review text there, so we do not quote Trustpilot. We therefore weight the Google signal the provider shows on its ratings page.

Frequently asked questions
When do I need a demand certificate instead of a consumption certificate?
A demand certificate is required or the better choice when consumption data is missing, mandatory cases under § 80 GEG apply, or third parties expect energy ratings that reflect the building condition. A consumption certificate often stays cheaper when it is permitted and you have sufficient consumption data from your heating bills.
What does an online demand certificate cost in 2026?
In this shortlist: €99 at energyausweis.de and mcenergieausweis.de, from €115 at online-energieausweis.org (October 2026).
Why are smartphone photos so important?
For a demand certificate, envelope and plant feed the balance. Good portals offer simple, fast photo uploads. That makes follow-up questions less likely and helps you keep your notary appointment on track.
Is a TÜV badge on the website enough?
No — it usually checks the portal, not the calculation. More: TÜV badge vs. quality seal.
Where is the full legal-safety checklist?
In Demand certificate providers compared — seven points and three detail tables. This Best-of short comparison adds customer feedback, ProvenExpert ratings and mobile capture to the review — it does not replace the checklist.
