Can anyone give me a rough idea of how

i only write APE , on Bing , and obtain it > https://www.apefacile.it/

The cost is related to the square metrage of your property.  The bigger the house the more it costs.   The geometra must now also do a revised planimetria of the house as part of the APE: 

Hi, You might find this article of your interest.http://www.luxury-law.com/ape-energy-certificate/It explains everything and also give you an idea of the costs!Hope it's helpful!

Hi... based on my experience APE may cost around 200 Euros, more or less that is the price for it, depending on a few circumstances it could be slightly more, but that's just for you to have an idea. This is when the architect or the engineer is actually going to do the inspection in person. This seems more accurate and you can use the professional there during the visit to ask some relavant questions and technical aspects which may be useful for you in the future to know. However, nowadays you can find some professionals/companies on line which provide you with the APE without an inspection, unless they deem it necessary. The price in this case is way cheaper, could start from 40 Euros. Browse on the internet for more info and speak to more than one professional in order to possibly choose one which is nearby and that can give you a reasonable price.Angelo
