Tips for proper maintenance of the gas installation with Reformia
To avoid fraud or scams, it is very important to know that the periodic gas inspection is not paid to the technician at the time of the inspection. The cost is included in the next gas bill, after the inspection is completed.
1. Cleaning radiators and boiler
Both radiators and the boiler are parts of the heating installation that tend to get dirty with use and over time. Because of this, they are devices that require periodic cleaning, just like other installations in the house. Additionally, during cleaning, you can check the proper condition of each part and, if not, alert the corresponding technician so they can carry out maintenance review if necessary.
2. Check the condition of hoses and flexible tubes
In the same way that boiler cleaning is carried out, it is also important to check the condition of the hoses and flexible tubes of the installation. This is because, due to their flexible nature, they are some of the parts that can deteriorate the most, especially if the material is in poor condition. When this happens, it is necessary to replace the damaged parts with new ones. However, it is important to do so before the parts show significant damage, as they could cause problems in the proper operation of the boiler.
3. Check the boiler pressure
Pressure is important both for the proper operation of the boiler and to save on its consumption. Pressure above normal will cause the boiler to not work properly, and lower pressure will cause it to not heat enough despite the fuel consumption being carried out.
To avoid fraud or scams, it is very important to know that the periodic gas inspection is not paid to the technician at the time of the inspection. The cost is included in the next gas bill, after the inspection is completed.

Steps to understand the cost of gas inspection in 2025
To avoid fraud or scams, it is very important to know that the periodic gas inspection is not paid to the technician at the time of the inspection. The cost is included in the next gas bill, after the inspection is completed.
1. Know when the inspection is mandatory
Gas inspections are mandatory every 5 years for natural gas installations in homes. This technical review ensures your installation's safety and costs between 120 € and 280 € depending on the inspection type. Complying with this legal requirement protects your home and prevents potential fines.
2. Contact your gas supplier
Contact your gas supplier to request the mandatory inspection. Most suppliers offer this service and can recommend certified technicians. A basic installation review starts at 150 €, while inspections with a review certificate cost around 250 €.
3. Schedule the inspection date with the technician
Once you contact your supplier, schedule a convenient date with the installer technician. The inspection process typically takes between 30 and 60 minutes. Make sure you're available to provide access to your gas installation.
4. Allow the installer technician access
On inspection day, give the technician access to all points of your natural gas installation. The professional will inspect pipes, connections, and appliances like boilers. This comprehensive review costs an average of 185 € and is essential for detecting potential leaks or safety issues.
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 of gas installation
Cost varies significantly depending on whether it's natural gas, bottled propane, or butane. Natural gas installations typically have lower inspection costs than bottled gas due to lower complexity.
Age of the installation
Older installations require more thorough inspections and may need additional tightness tests. This can increase technician time and consequently the final cost.
Number of consumption points
Homes with multiple gas-powered appliances (boiler, stove, water heater, radiators) require more inspection time than those with a single consumption point.
Geographic location and gas distributor
The price of periodic inspection varies by region and the gas distribution company contracted. Some distributors offer more competitive rates than others.

What is the purpose of periodic inspection of the natural gas installation?
To avoid fraud or scams, it is very important to know that the periodic gas inspection is not paid to the technician at the time of the inspection. The cost is included in the next gas bill, after the inspection is completed.
In the cost of the Individual Receiving Installation (IRI) inspection, two factors are taken into account:
*Taxes not included
The purpose of periodic inspection of the natural gas installation is closely related to its condition and safety requirements. The basic objective is to verify that all installation elements comply with regulatory requirements and are in perfect condition.
In addition, it is worth noting that a properly maintained installation that does not have deficiencies will operate optimally, so periodic inspections, in a way, also contribute to energy savings.
Mandatory periodic inspections of the gas installation are carried out every five years. If favorable, a natural gas installation certificate is issued. If unfavorable, it will be necessary to fix the faults it presents; in fact, if they are very serious, the installation can be sealed.
- Very serious anomalies: they affect the safety of the installation, which is why it is sealed. In that case, the customer must request the distribution company or an authorized company to proceed with the corresponding repair.
- Serious anomalies: although they affect the operation of the installation, they do not pose a safety risk. The procedure is the same as for very serious anomalies.
- Minor anomalies: these are small faults for which the user has 15 days to resolve them, without the installation being sealed. After the repair, a new inspection is necessary.
