What we solve
Checking whether solar panels are legalised means reviewing the installation's paperwork and cross-checking it against itself: that the supply point code, the account holder, the power rating, the inverter and the self-consumption arrangement all say the same thing, and that the CAU code exists and belongs to your supply. We do it without a site visit, using what you send us, and we sort the outcome into four states: correct, incomplete, inconsistent, or technical work required.
Which authority is involved depends on what is missing. Registering self-consumption and notifying the installation fall to the regional Industry office of the Generalitat; the self-consumption code is assigned by your grid operator; surplus compensation is applied by your electricity retailer. This service files nothing with any of the three: it tells you which one has to step in, and with which document.
When you need it
- You have bought a house that already had panels on the roof.
- The original installer has disappeared or does not reply.
- You never received the final paperwork for the works.
- Your electricity bill shows no self-consumption and no surplus.
- You want a battery, more panels or a new inverter and do not know where you stand.
What happens if you do not check
- Any later work is quoted blind and can get more expensive once the real state of things shows up.
- If surplus compensation was never switched on, every bill keeps failing to credit the energy you have already exported.
- When you sell or let the property, missing paperwork turns up in the worst possible week.
Who can do this, and when you are better off doing it yourself
This check requires no qualification: the holder of the supply can ask for their own data. If your case is one of these three, keep the 49 €.
Ask your grid operator and your electricity retailer for the paperwork yourself.
If you have time, you know exactly what to ask for and only one specific document is missing.
It costs you your time
Ask the installer who did the works for the documents.
If the company is still trading and answers. It is the fastest route and it costs nothing.
No money involved
Look up the self-consumption registry yourself.
If you already know your CAU code and just want to confirm the registration exists.
It costs you your time
The €49 come back in full if you hire the fix
The assessment is not a preliminary stage and not a hook: it is a complete deliverable, with its own report and its own invoice. It is also a credit. If within 30 days you hire a service of €199 or more from us, the €49 come off that invoice in full. The work that follows starts at €199, and its exact price is settled once the report says what needs doing.
How the credit works
- It applies once, against a single later service. It is not split across two invoices.
- That later service has to be hired within the following 30 days and cost €199 or more.
- It creates no right to a cash refund and it cannot be transferred to someone else.
- If that later service is cancelled with a right to a refund, the credit is reinstated for whatever time was left on it.
How it shows on the invoice
The credit is applied as a discount that reduces the taxable base of the invoice for the larger service. The assessment invoice is neither amended nor cancelled, because the assessment really was delivered and that invoice is correct.
If the report concludes that nothing needs fixing, there is nothing to hire afterwards and that is the end of it. Knowing your paperwork is in order is also a result, and it is what saves you paying for a regularisation you do not need.
What is included and what is not
What is included
- An inventory of every document you send us.
- A check that the supply point code, the account holder, the power rating, the inverter and the self-consumption arrangement all say the same thing.
- Identification of the CAU code available, or of the need to request or verify it.
- Classification of the situation into four categories: correct, incomplete, inconsistent, or technical work required.
- A map of the next steps, with a fixed price for the services needed whenever their scope can be determined.
One round of revisions included
What is not included
- Issuing new certificates.
- A site visit, unless it is contracted separately.
- Filing anything with the Industry office, the grid operator, the retailer or the council.
- Electrical repairs of any kind.
- A guarantee of obtaining documents that are not legally accessible.
What falls outside is covered by: legalising an existing installation, recovering the paperwork when the installer has disappeared.
How it works, step by step
Four steps. Two are ours and carry a committed turnaround, one is yours, and the fourth only appears when something has to be asked of your grid operator.
- Step 1Your part
You fill in a form that takes five to ten minutes and upload whatever you have.
We need: The completed form and the uploaded documents. - Step 2We do this
We inventory what you sent and cross-check supply code, account holder, power rating, inverter and arrangement.
Our turnaround: 1 working day
Counted from: The moment the form is complete.
We do not promise: That paperwork will appear if it does not exist or is not legally accessible.
- Step 3We do this
We classify the situation and hand you the report with the map of next steps.
Our turnaround: 1 working day
Counted from: The end of the document review.
We do not promise: A verdict on something that cannot be verified with what you sent. That the outcome of the report will be favourable.
- Step 4Depends on your grid operator
When the CAU code is missing or the registered arrangement needs confirming, the answer is down to your grid operator.
The timing is set by the authority. We do not commit to it.
What we need from you, and what you get
The documents we will ask you for
Three are essential and the rest help. If all you have kept is the electricity bill, the service still makes sense: rebuilding the record is exactly the job.
Essential
Your CUPS supply point code and your latest electricity bill
It is the only thing that identifies your supply without ambiguity, and it is what tells us whether compensation is active.
Essential
The full address of the installation
The municipality decides which council is involved and under which building regime.
Essential
ID document or company tax number of the current account holder
Without knowing who holds the supply today, we cannot spot the commonest mismatch, which is the supply holder and the installation owner not being the same person.
If you have it
Whatever you have kept: installation certificate, technical report, project, CAU code, letters from the grid operator or the retailer
The more you send, the less has to be rebuilt. If you have nothing at all, the service still makes sense.
If you have it
Photographs of the inverter and of its rating plate
The rating plate settles in a minute the power rating arguments that take an hour on paper.
What we hand over, and what it is not
Short report on the legal state of the installation
It is not a certificate that your installation is legal, and it is not a document you can rely on before the authorities.
Document checklist with a traffic light
It does not replace the original documents: it says which you have and which are missing.
A specific list of issues and a map of the next steps
It is not a binding quote for the issues whose scope cannot yet be determined.
The service counts as delivered when the report with the map of next steps is handed over. It does not depend on you liking the outcome, on the installation turning out to be correct or incorrect, or on us obtaining documents that are not legally accessible.
What it costs
Two published prices, both with VAT inside. The first is the assessment this page is about. The second is for whoever already knows that the only thing missing is the self-consumption code and does not need anything classified.

Neither one carries public fees. Checked on . If one did come up in your case, it would be paid to the authority in your name and it would not be our revenue.
What happens if yours is not this case
Paying does not start the work. Once payment is received, we check that the service you bought really matches your case and tell you the outcome within two working days at most. If it matches a different service, we tell you which, what it costs and why, and you choose between accepting the change or withdrawing with a full refund. If it matches none of them, the whole amount is returned with nothing held back.
How long we take, and what is not up to us
Our turnaround
2 working days
Counted from: The form being complete and the documents uploaded.
What this turnaround does not cover
- A verdict that cannot be verified with the paperwork available.
- A reply date from your grid operator or your electricity retailer.
- That the installation ends up legalised: this classifies the situation, it does not put it right.
What depends on third parties
Your grid operator
Confirmation of the CAU code or of the registered self-consumption arrangement.
No date commitment on our side.
Your electricity retailer
An explanation of why the bill shows no surplus compensation.
No date commitment on our side.
We commit to filing a complete application and following it through. The decision date is set by the authority, not by us, so we do not promise it.
If the only thing missing is the CAU code
The CAU is the code that identifies your self-consumption installation to the grid operator and to the authorities. It hangs off your CUPS supply point code, so it looks similar without being the same number. When a procedure stalls, it almost always stalls there. If you already know that is your problem, there is no need to go through the assessment. We handle it for €69 with VAT inside.
One warning that goes in front of the price and not in the small print: the CAU is assigned by the grid operator, not by Captia. What you are buying is having someone else file it and chase it, and having the code checked against your supply and filed. If you have an account on your grid operator's portal and time to chase it, requesting it yourself is better than this.
What is included
- Identifying the grid operator that serves your supply.
- Reviewing the supply point code and checking whether the CAU code already exists.
- Preparing and filing the request through the official channel, acting as your representative where the grid operator allows it.
- Reasonable follow-up of the request.
- Delivery of the CAU code received and filing it in your record, with the supply-to-code sheet.
What is not included
- Grid access and connection permits where they are required.
- The full regional legalisation procedure.
- Electrical installation certificate, technical report or project.
- Any guarantee about how long the grid operator takes to reply.
- Creating or issuing the code: the CAU is assigned by the grid operator.
What falls outside is covered by: legalising an existing installation, switching on surplus compensation.
Where this service stops
- If the installation is not exempt from grid access and connection permits, the CAU code appears inside that procedure and this stops being the right service.
- If the grid operator demands an authorisation to act that the account holder cannot sign, the order cannot be carried out.
- If what is missing is not the code but a correction to data already registered, that is a different service.
The CAU turnaround, also split in two
Our turnaround
1 working day
Counted from: Us having the supply point code, the holder's ID document and the signed authorisation to act.
What this turnaround does not cover
- The date on which the grid operator will issue or communicate the code.
- That a CAU code exists at all, if the installation was never registered.
- That your installation ends up legalised: this unblocks one step, it does not close the file.
What depends on third parties
Your grid operator
Assignment or communication of the self-consumption code.
No date commitment on our side.
We commit to filing a complete application and following it through. The decision date is set by the authority, not by us, so we do not promise it.
Edge cases
What we assume we are working on
- The self-consumption installation is already built and running.
- The current account holder for the supply is identified and can prove it.
- The paperwork is either in your hands or is something you can request.
What stops the standard scope
- If a physical modification of the installation turns up, the standard scope stops and an extension is issued.
- If the case requires a full project, an authorised inspection, grid access and connection, or touches a planning issue, it stops being this service.
If any of those turn up, we stop and issue an extension with its price before going any further. Nothing extra is ever charged without you agreeing to it.
The mistakes we see most
Trusting a folder full of paper
Having a quote, a delivery note and warranties is not having the file. What counts is the notification to the Industry office, the installation certificate and the self-consumption registration.
Mixing up the CAU and the CUPS
They look alike, so a code belonging to another meter on the same property slips through. Checking that the code and the supply are the same one is the first step, not simply getting hold of a number.
Assuming the arrangement is the one you were told
The registered arrangement decides how your energy is settled, and it does not always match what the owner believes they have. If it does not match, it shows on the bill every month.
Frequently asked questions
- Does this certify that my panels are legal?
- No. It classifies the documentary state of your installation and tells you what is missing. A certificate is a different thing: it is issued by whoever is qualified to sign it, and it is requested afterwards if it turns out to be needed.
- What if it turns out everything is fine?
- Then we tell you so and that is the end of it. Knowing that nothing needs doing is also a result, and it is what saves you paying for a regularisation you do not need.
- What is the CAU and why are you asking me for it?
- It is the code that identifies your self-consumption installation to the grid operator and to the authorities. It is the first thing we check, because almost every inconsistency shows up there.Source: Real Decreto 244/2019, de 5 de abril, de autoconsumo de energía eléctrica. Verified on .
- Do I lose the 49 € if I then hire the fix?
- No. If within 30 days you hire a service of 199 € or more from us, the 49 € come off that invoice in full.
- What exactly is the CAU?
- It is the code that identifies your self-consumption installation to the grid operator and to the authorities. It hangs off your CUPS supply point code, so it looks similar but it is not the same number. It lets any procedure know which installation is being discussed.Source: Real Decreto 244/2019, de 5 de abril, por el que se regulan las condiciones administrativas, técnicas y económicas del autoconsumo de energía eléctrica. Verified on .
- Do you create the CAU for me?
- No. The CAU is assigned by the grid operator. What we do is identify which one is yours, check whether the code already exists, file the request on your behalf and follow it until there is an answer.
- Can I request it myself at no cost?
- Yes. Grid operators let the account holder request it from their private area. If you have an account on the portal and time to chase it, that route is better than this one. The 69 € buy having someone else do it, checked against your supply and filed.
- How long does it take?
- We file the request within one working day of having your signed authorisation. How long the grid operator then takes to reply is up to them, and we do not commit to it.
- Which documents do I need to hand?
- The CUPS code, which appears on your electricity bill; your ID document or company tax number as holder of the supply; the full address; and the authorisation to act, which we prepare and you only have to sign.Source: Ley 39/2015, de 1 de octubre, del Procedimiento Administrativo Común de las Administraciones Públicas. Verified on .
- What is the commonest mistake?
- Accepting a CAU code that belongs to a different supply point, usually a second meter on the same property. That is why the first step is checking that the code and the supply are the same one, rather than simply getting hold of a number.
What usually comes after the report
The report ends in a map of next steps. These are the three commonest destinations, and the €49 come off any of them if you hire within the window.
If you would rather understand the whole circuit before hiring anything, we set it out in solar paperwork from start to finish, and the rest of the procedures hang off permits and legalisation for your installation.
