to be quite honest i dont know why one is needed here in spain, most people have only wood burners single glazing in there windows and cold tiled floors seems daft to me as most will get the lower rateing and who is going to take any notice of it ?.we have payed out 400e  x 3 times for cedulas now this maybe its another way for someone to make money  :-/ .anyone know what the cost will be for the paperwork ?
