Eco loan at zero rate: do eco-renovation work.

The eco loan at zero rate is not exactly one of the types of mortgage: it is actually a loan intended to finance the completion of renovation or energy improvement works. Because it is linked to the optimization of the energy performance of a home, and because of its homophonic proximity to the zero rate loan (proximity which can cause confusion), it is nonetheless worth mentioning the eco PTZ in this part of the guide.

The eco loan at zero rate, what is it for?

The eco loan at zero rate, what is it for?

If the classic PTZ is a type of home loan intended to partially finance the acquisition of a home, the eco PTZ, allows you to obtain a loan to carry out energy renovation work in a home.

These works must aim to improve the energy performance of the building, make it more energy efficient, optimize its comfort and limit its greenhouse gas emissions. Note that it is possible to apply for an eco loan at an additional zero rate, in addition to the first, to carry out other work and provided that the amount capped at $ 30,000 is not exceeded for two joint credits.

Constraints of eco PTZ

Constraints of eco PTZ

The eco loan at zero rate makes it possible to borrow an amount of up to $ 30,000, only to finance so-called “eco-renovation” works. Concretely, the amount is capped according to the number of works undertaken: $ 10,000 for a single action, $ 20,000 for two types of work, $ 30,000 for three types of work and more, ditto for work aimed at “performance overall energy ”, and finally $ 10,000 for non-collective sanitation.

The eco PTZ must be reimbursed over a period of 10 years maximum (15 years for three types of work).

The accommodation concerned can be the principal residence of the subscriber or an accommodation which he puts out to rent, the only condition in this sense being that he is the owner (an occupant cannot ask to benefit from an eco loan at a rate zero). The building itself must have been built before 1 January 1990 in France only (before 1 May 2010 for Martinique, Guadeloupe, Reunion and Guyana).

The works concerned must:

  • Be part of a “bouquet” of work;
  • Achieve a minimum level of energy performance;
  • Aim to rehabilitate a non-collective sanitation system by replacing it with a less energy-consuming device.

It is important to know that obtaining an eco PTZ is subject to another obligation: the work must be carried out by companies or craftsmen approved RGE (Recognized Guarantor of the Environment).

What works are eligible for the zero-rate eco loan?

What works are eligible for the zero-rate eco loan?

To be able to benefit from the zero-rate eco loan, an owner must undertake work that is part of a “bouquet”, that is to say coherent and drawn from at least two categories among the following:

  • Roof insulation work,
  • Insulation works for exterior walls,
  • Insulation work on doors and windows leading to the outside,
  • Installation of a heating or domestic hot water production system,
  • Installation of a heating system using renewable energies,
  • Installation of a domestic hot water production system using renewable energies.

These categories make it possible to choose works which adapt to particular cases, each accommodation being different. The concrete operations are then defined in good agreement between the owner and the craftsman / entrepreneur who comes to take care of them.

It is also possible, in order to obtain an eco loan at zero rate, to have a thermal study (different from the DPE) carried out which determines which works are best suited to the building and its specific needs. The objective is then to do work to improve its “overall energy performance”.

Some special features to know

Some special features to know

The eco PTZ can be combined with other aids:

  • The zero rate loan for home ownership;
  • The energy transition tax credit;
  • Aid from local authorities;
  • Aid from the National Housing Agency;
  • Energy savings certificates.

Another peculiarity of the eco loan at zero rate is that it can be mobilized in co-ownership. Its amount is then capped at $ 10,000 per unit concerned, with an increase of up to $ 30,000 per unit if the trustee initiates a “bouquet” of work encompassing at least three actions. Each co-owner can also make an individual request for an eco loan at zero rate as part of the work carried out by the entire co-ownership.
