2.4·GWh/ month
of certified energy savings through Sanwa every month
Savings calculation, verification by an accredited body, documentation and connection with Obligated and Delegated Parties — all from a single platform.
We believe energy efficiency should be simple, financially attractive and verifiable. That is why we have automated the CAE system on a single platform.
At Sanwa we take care of auditing the savings, validating them with an accredited body and connecting them with Obligated or Delegated Parties. You decide to carry out the action; we do the rest.
We work with you in the way that fits your profile. If you have a one-off CAE, we handle it directly; if you operate at volume, we open the platform to you.
If you want to monetise it, get in touch with us. We take care of all the paperwork and pay you in the same week the certificate is issued.
Installers, manufacturers, engineering firms and associations launch, supervise and settle their case files from a single panel — with all the traceability and controls of the Sanwa workflow.
Why with Sanwa
It doesn't matter whether you're an installer, an ESE, an industrial company or an Obligated Party: Sanwa centralises savings calculation, verification, documentation and settlement. You only choose the action.
Request my free studyWe take care of the savings calculation, the documentation, the verification and the connection with the Delegated Party. You don't lift a finger on paperwork.
You pay nothing: not before, not during, not after. And we combine the value of the CAE with IDAE grants and tax deductions to minimise the remaining cost of each action.
Actions are backed by qualified installers and verification by accredited bodies in accordance with Real Decreto 36/2023.
The four pillars that set Sanwa's CAE operations apart from any traditional agency or intermediary.
From registering the case file on the platform to the issuance and settlement of the certificate. Our automation engine removes the usual documentation and verification bottlenecks.
You don't wait for the Delegated Party to pay us before you get paid. When the certificate is issued, we settle it against your account within that same weekly cycle.
The end client chooses at their own discretion, case file by case file, what fee they keep. Sanwa passes on the rest of the settlement in full, and the traceability stays on the platform.
Case-file status, certified kWh, estimated amount and final amount, agreed fee, attached documentation and conversations with the Delegated Party — accessible 24/7 from the platform.
We centralise coordination with installers, verifying bodies and Obligated/Delegated Parties. You only decide to carry out the action and choose the fee.
Many CAEs require prior documentation: legalisation before the Industry authority, regional registration, the Energy Performance Certificate (CEE before and after) or technical reports. If the action doesn't have them yet, it's not a problem — we process all the documents associated with the case file in parallel, from the same platform and our full catalogue of services.
If you're an individual, we sort it out by talking to you. If you're a company or self-employed, you launch and supervise it from the platform.
No need to use platforms. No paperwork.
Talk to SanwaRegistration
From the web form, bulk CSV upload or an API call. The platform detects the applicable CAE datasheet.
Calculation
The engine generates the technical report and the savings calculation following the official methodologies, with no manual intervention.
Signature
The owner and installer sign from the platform itself. The case file is then ready for verification.
Processing
We package the case file and send it to an ENAC-accredited certifier, which validates the savings independently. From there it goes to the regional manager and to MITECO.
Tracking
Every status change, validation or document request appears on your dashboard instantly.
Settlement
You define the fee for each operation and the platform automatically distributes the settlement the week it is issued.

* Market times reflect the usual timelines of a traditional agency with manual processing. Sanwa times are those we are seeing in production thanks to the automation of the administrative flow.
The right to the savings never passes through the installer: the end user always cedes it directly to Sanwa. From there, the official chain reaches the Obligated Party that pays for the CAE. Some intermediate links are optional depending on the case.
The party that carries out the efficiency action (home, industry, tertiary sector...). They cede the savings directly to Sanwa.
We receive the cession of the savings, calculate them, handle the verification and connect with the Delegated or Obligated Party.
Groups case files together to submit them to the Obligated Party. Optional depending on the case.
An energy retailer legally obliged to meet a savings quota. It is the party that pays for the CAE.
Their role is document management: they collect from the end client the photos of the action, the invoices and the rest of the documentation needed to process the case file. They are not part of the cession chain — the savings are always ceded directly from the end user to Sanwa — but they are paid for that time and work of collection.
* The Sujeto Delegado is optional: Sanwa can deliver the certificate directly to the Sujeto Obligado when the case allows it.
