If you sell
The notary asks for the registered certificate before the sale is signed. The buyer receives the original.
An energy certificate in Xàtiva, with an engineer's visit
The energy performance certificate rates how much energy your home uses, with a letter from A to G, much like the EPC in the UK. It is compulsory before you sell or let a property in Spain. We do it with a real visit, sign it and register it with the regional government (GVA) for you.
From 149 €, VAT included, by floor-area band.
When it is compulsory
You need the certificate before selling or letting a home. Not at the signing: from the very first advert. The energy label must appear in any offer, including the property portals, and advertising without it is an offence that can be fined.
If you let
The tenancy contract must come with a copy of the certificate. The tenant has the right to see it beforehand.
If you advertise without the label
Publishing a listing without the energy rating carries a fine. Far more expensive than the certificate itself.
What the visit includes
Spanish law requires a visit to the property before it can be certified. We always do it, with a qualified, professionally registered engineer. This is what happens from your first call until you have the label.
1
We measure the home properly
Floor areas, orientation, windows, walls and roof. No templates filled in from a desk: what gets certified is what is actually there.
2
We check the installations
Boiler or heat pump, air conditioning, hot water and, if you have them, your solar panels. Everything counts towards the final letter.
3
We calculate and sign
A qualified engineer calculates the rating with the official software and puts their own name to the certificate.
4
We register it for you
We file the certificate with the regional government (GVA) register and hand you the label, ready for the listing or the notary.
What it costs
The price goes by band of built floor area, a figure you already know. We confirm it by measuring during the visit and, if your home falls into another band, it is corrected before invoicing.

What it depends on
- Up to 120 m² of built floor area: 149 €.
- From 121 to 200 m²: 199 €.
- From 201 to 300 m²: 279 €.
- Above 300 m², a complex detached house or a whole building: quoted separately.
- Outside La Costera, travel is quoted separately.
We travel by area, and that affects your date
We group the visits in one area into a single run. That is what holds the entry price where it is, so when you ask for a date we offer you the next run through your town first. If that day does not suit you we book another one: you just need to know the diary moves by area rather than by order of calling.
Outside La Costera
We still come. What changes is that the travel is either grouped with other visits in your area or quoted separately, and either way we tell you before we accept the job, never after.
Registration with the regional government (GVA), included
An unregistered certificate is no use for selling or letting. In the Valencian Community it is entered in the regional register of building energy certification, and that entry is what produces the official label.
- The fee. It is not our money: it is paid in your name and the receipt is issued in your name. It sits outside the price above and is itemised in the quote, at whatever rate the Valencian Community register of energy performance certificates has in force on the day of your visit. We confirm it with the register itself before sending you the quote. Last regulatory review of this service: .
- The timing. Our part is five working days from the visit: calculation, signature and filing. When the register issues the entry number is up to the regional government, and that we do not promise. We file it complete first time and follow it up.
- The paperwork. You receive the signed certificate, the label and the proof of registration. Everything the portal, the estate agent or the notary will ask for.
Your certificate shows how much solar panels would help
The certificate is not just a piece of paper for the advert. It measures how much non-renewable energy your home uses, and that is where solar panels move the needle: they almost always raise the letter. If you are thinking about putting solar panels on your home, the certificate tells you where you start from and how much you would gain.
A certificate before and after building work
When what has to be proven is an improvement, one certificate is not enough: it takes two, the state before and the state after, calculated on the same criteria and each registered at its own moment. The first one has a single possible window, and that is before anything is touched. Once the work has started it can no longer be issued, and there is nothing left to compare against. They are two certificates and they are ordered as such, each in its own floor-area band.
One of the uses of that pair is the national income tax deduction for energy improvement works (Real Decreto-ley 2/2026): 40% on a maximum base of 7,500 euros, for works carried out up to 31 December 2026, with the later certificate registered before 1 January 2027. Figures checked on 16 August 2026.
Whether that deduction applies to you depends on your circumstances, how you pay for the works and any grants you have received, and it is settled between you and your tax adviser before the Spanish tax office. We issue and register the certificates; we do not file your tax return and we take no part in it. The details, and the rest of the deductions, are in the guide to 2026 grants and deductions.
Frequently asked questions
What do I need to get started?
The address of the property and little else. The cadastral reference is enough for us; we gather everything else during the visit.
What exactly does it cost?
By band of built floor area: 149 € up to 120 m², 199 € from 121 to 200 m² and 279 € from 201 to 300 m². Above that, a quote. All figures include VAT. The regional registration fee sits outside the price and is itemised separately, because it is not our money.
What if the real floor area is not the one I gave you?
The band is corrected before invoicing, never afterwards. We measure it during the visit and, if the band changes, we tell you there and then.
I have seen certificates for ninety euros. Why does yours cost more?
Because it includes a real visit to your home. A good part of the market is turned around in forty minutes from a template, without going. If all you need is the paperwork to close a deal, the cheap certificate is a legitimate choice and we will say so. If you want the rating to resemble your actual home, someone has to measure it.
How long does it take?
Our own work is five working days from the visit: calculation, signature and filing with the register. When the regional register issues the entry number is not up to us, and we do not promise it.
Does the certificate expire?
Yes. Ten years at most, or five if the rating comes out as G. The date appears on the label itself. If yours has expired and you want to sell or let, we prepare a new one.
What if my home gets a poor letter?
Legally, nothing changes: you can still sell or let. The upside is that the certificate tells you, measure by measure, what would improve the letter and the consumption.
Does it work for the tax deduction on energy improvement works?
The certificate is one of the documents that deduction requires, and proving an improvement takes two of them: the state before the works and the state after. We issue and register both. Whether the deduction applies to you depends on your circumstances, how you pay for the works and any grants you have received, and that is settled between you and your tax adviser.
