The main objective of the work under study is to find means and tools to achieve the reduction of energy poverty in Spain: creation of a social bonus of services that allows politicians to make decisions for it. This energy bond or “social service bonus” includes energy costs: electricity and gas, telecommunications (Internet), as well as other supplies (water and discharge). The first thing that arises is the reduction of supply costs by optimizing the installation and contracting systems. We start from the data provided from the previous study on energy demand and the corresponding energy improvement and sustainability measures, in a public building of social housing in C / La María, in Seville. This study shows that it is possible to achieve energy self-sufficiency and improved comfort in an efficient and cost-effective way in the short term. Next, the reduction of costs by modifying the contracting systems and the study of the social bonuses offered by the different companies in the different supplies are studied. With the data obtained, it is proposed to create a “social bonus of services” where the total cost of them could be reduced from 80 to 90% of the current payment. Finally, it is proposed that the social bonus of services can have the same treatment as the rent, with a system of subsidy or bonus of the same depending on the family and income parameters of the tenants.
