Gas Boiler Maintenance: What Does It Cost?

Maintaining a gas boiler costs an average of €120.

The service price typically ranges between €90 and €150.

Gas boiler maintenance – recommended every 2 years.
Although the law does not specify fixed maintenance intervals for gas boilers, professional servicing and maintenance are necessary to ensure safety and proper operation.

Legally, the chimney sweep must inspect the exhaust system every 2 years to make sure everything is functioning correctly. During this same period, you should also have your gas boiler serviced — ideally once a year, as many manufacturers require annual maintenance to keep the warranty valid.

On average, gas boiler maintenance costs around €120.

The following factors can influence the overall price:

• Type of gas heating system

• Possible damage or contamination

• Experience and qualifications of the technician

How Much Does Maintenance by a Professional Cost?

If you hire a qualified technician to service your gas boiler, you can expect to pay €90 to €150.

If your property is located outside the service area, many tradespeople charge an additional travel fee — depending on the region, this can range from €10 to €50.

Can I Deduct the Costs from My Taxes?

Yes, you can deduct the costs of gas boiler maintenance and hydraulic balancing as household-related services from your taxes.
Typically, 20% of the labor costs are refunded by the tax office as a tax credit.
Additionally, hydraulic balancing can help reduce heating costs, allowing you to save money in two ways.

As a landlord, you can also claim these expenses as advertising costs, since maintenance measures for rental properties are tax-deductible.

Rental Property: Who Pays for the Gas Boiler Maintenance?

Although landlords are always responsible for the gas boiler, they are allowed to pass on the maintenance and heating system costs to tenants as part of the operating costs.

It is important to list maintenance and repair costs for the gas boiler explicitly in the rental agreement to make them transferable.

As a guideline:

• For a single-family house, landlords can charge around €100 per year to tenants for boiler maintenance.

• For apartments, the reference amount is about €50 per year.

Tenants have the right to review the complete maintenance invoice for verification.
However, landlords cannot require tenants to sign a maintenance contract themselves — the landlord must handle the contract with the heating installer.

Who Is Responsible for Gas Boiler Maintenance?

The maintenance of the gas boiler is the responsibility of the operator of the gas installation, usually the building owner.
The owner is responsible for all building systems and must also monitor for possible issues such as heating malfunctions or gas odors between maintenance periods.
If such problems occur, the owner must arrange for repairs immediately.

What Does a Maintenance Contract Cost?

It is advisable to sign a maintenance contract with a trusted heating technician.
This contract ensures that your gas boiler is inspected regularly.
You won’t have to remember to schedule maintenance, as the technician will contact you directly and remind you of the upcoming service.

Depending on the agreement, a maintenance contract costs approximately €150 to €200 per service.
If major repairs are required, the tradesperson will charge extra for those services.
