Until a few years ago the energy class was a formality to settle before completion. Today it has become a matter of price. On Lake Garda, where a significant share of demand comes from Germany, Austria and the Netherlands — countries where energy efficiency is part of the culture — the EPC can make the difference between a quick sale at a good price and a negotiation downwards.
What the EPC is and why it is mandatory
The EPC (Energy Performance Certificate) certifies the energy efficiency of a property, assigning it a class from A4 (the best) to G (the worst). It indicates how much energy the home consumes for heating, cooling, hot water and other uses.
To sell it is mandatory: the class must be stated in the listing and the EPC attached to the notarial deed. Its absence carries penalties.
The energy classes
The scale runs from A4 to G. The higher the class, the lower the consumption and running costs:
New builds start in the highest classes: an example are the apartments with pool in energy class A3 at Residence Katya 2 in Desenzano del Garda, where high efficiency means low consumption and greater value over time.
How much the energy class affects the price
The effect on value is now concrete and works in two directions:
- Premium for high classes: all else being equal, a class A or B justifies a higher price (low running costs, high comfort).
- Discount for low classes: a class F or G becomes a negotiating lever, because the buyer factors in future renovation costs.
Example. Two identical apartments in the same building: one in class B (renovated), one in class G. The first attracts more enquiries and sells sooner; on the second, the buyer tends to discount the estimated cost of works.
Note, however: the energy class is one of the value factors, not the only one. Location, view and general condition remain decisive (see the guide on how much your home on Lake Garda is worth).
Why it matters (even more) to foreign buyers
On Lake Garda the energy factor is amplified by the international profile of demand. German, Austrian and Dutch buyers:
- come from countries with high energy standards and are used to reading the energy class;
- assess running costs over the long term, not just the purchase price;
- are often willing to pay a premium for an efficient, well-documented property.
For the seller on Lake Garda: a good energy class is not just another number in the listing — it is a selling point that speaks directly to your most solvent buyer. It is worth highlighting it with clear data and documentation.
How to obtain the EPC
- Who draws it up: a qualified, independent technician — the energy assessor — after an on-site inspection.
- Validity: ten years, unless works change the performance or system maintenance is neglected.
- Registration: it must be registered in the regional energy register.
⚠ Caution. Beware of "online" EPCs issued without an inspection for a few euros: they are irregular and can create problems at completion. A proper EPC requires a technician to visit the property.
Is it worth renovating before selling?
It is the key question, and the answer depends on the cost-benefit ratio. Major works are not always worth it: what matters is whether the higher sale value exceeds the spend.
| Work | Impact / when it makes sense |
|---|---|
| Condensing boiler / heat pump | Good improvement at limited cost |
| Replacing windows | Improves class and perceived comfort |
| Efficient air conditioning | Appreciated, moderate cost |
| LED lighting, small measures | Cheap, useful for positioning |
| External insulation / deep renovation | Only if the added value clearly exceeds the cost |
The right strategy is decided case by case, before listing: sometimes a small targeted work is enough; other times it is better to price the property correctly "as is" and leave the renovation to the buyer. It is a choice we assess together during the valuation.
Frequently asked questions
Is an EPC mandatory to sell a home?
Yes. The energy class must be stated in the listing and the EPC attached to the deed. Its absence carries penalties for the parties.
How long does an EPC last?
Ten years from issue, provided you meet the system maintenance requirements and carry out no works that change the energy performance.
Who can draw up the EPC?
A qualified, independent technician — the energy assessor — after an on-site inspection. The certificate must be registered in the regional energy register.
How much the energy class affects the price?
Increasingly so. A high class (A or B) can translate into a premium; a low class becomes grounds for negotiating down. On Lake Garda the effect is amplified by foreign buyers.
Is it worth improving the energy class before selling?
It depends on the cost-benefit ratio. Simple works (boiler, windows, air conditioning) add value at limited cost; deep renovations only if the added value exceeds the cost.
Can a class G home be sold?
Yes: a low class does not prevent a sale, but it affects price and timing. The right strategy is to price consistently and, where worthwhile, consider small improvements.
