Unfortunately, nothing in life is free and the services provided are reliant on everyone registering at the town hall, effectively on the electoral roll, so the money comes from central government (i.e. your taxes). Same the world over!
It would be a good idea to encourage people to register if we want the perks on site such as rubbish bins and patrols, etc.
You need to go to Algorfa town hall with your passport and deeds to the property. they also sometimes want to see a utility bill for the property, depending on who you see, they will then give you a padron.
