A basic installation project for a home can cost on average around 1.000 € - 1.200 €. The price may be modified depending on the installations included and also if technical assistance on site or certified projects are needed. The complexity of the work can also significantly increase the budget.
1. Determine the type of installation needed
Identify which installation systems your home requires: electricity, water, air conditioning, gas, or thermal installations. An installation engineer can prepare complete projects starting from 150 € for specific calculations. This initial definition is crucial for obtaining accurate quotes tailored to your actual needs.
2. Gather information about your property
Gather detailed information about your home: square footage, construction year, current systems, and specific requirements. This information is essential for the engineer to provide accurate quotes in ranges from 800 € to 5,000 € depending on complexity. Include blueprints, energy certificates, and photos of existing installations if available.
3. Request quotes from multiple engineers
Contact at least 3-4 installation engineers to request detailed quotes. Services vary between Basic (800 € - 1,200 €), Standard (1,500 € - 2,500 €), and Premium (3,000 € - 5,000 €) levels. Specify whether you need blueprints, calculations, or complete projects for electricity, water, and air conditioning starting from 150 € each.

4. Review project scope and details
Carefully review each quote to confirm what it includes: technical drawings, installation calculations (150 € per item), specific system projects, or inspections. Verify whether quotes cover only design or also supervision and installation work. Details differentiate a basic from a premium quote.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Type and complexity of installations
Price varies significantly depending on whether these are basic electrical, plumbing, gas installations or more complex systems such as HVAC or home automation. Projects requiring multiple specialties typically increase the budget by 30-50%.
Professional certification and administrative processing
Projects requiring professional body certification or administrative approval have an additional cost of approximately 200-400 €. This documentation is mandatory for major works or changes in space use.
On-site technical assistance
If the engineer needs to oversee the execution of installations on-site, technical supervision fees are added, ranging around 400-600 € depending on project duration. Without this assistance, the budget is for the project only.
Property size and layout
Larger properties or those with complex layouts require more analysis and design time. A 200 m² property can cost 40-60% more than a 100 m² one with similar installation features.
