Is boiler servicing mandatory?

Yes. In France, annual servicing of a gas or oil boiler is mandatory for every home, whether occupied by the owner or rented. This obligation applies as soon as the rated output is between 4 and 70 kW (the most common residential range).

The goal: guarantee safety (CO leak or explosion risk) and the heating system’s energy performance.

To remember: the servicing certificate issued by the professional must be kept. Your insurer may ask for it after a heating-related claim.

What does decree no. 2009-649 say?

Decree no. 2009-649 of 9 June 2009 requires:

  • An annual inspection by a qualified professional (PG, PGN, or QualiPAC depending on type)
  • Delivery of a servicing certificate to the owner or tenant
  • Checks on 3 essential points: safety, energy efficiency, pollutant emissions

For heat pumps, annual servicing is also recommended and sometimes required by the manufacturer to keep the warranty.

Penalties and consequences of skipping it

The consequences of missed servicing go beyond a fine:

  • Insurance - refused cover after a claim (fire, carbon monoxide poisoning)
  • Performance - 10 to 12% extra consumption (ADEME)
  • Rental - the landlord remains responsible; the tenant can request servicing
  • Resale - no certificate means a discount or a blocked sale
  • Fine - up to €1,500 for individuals (article R224-41-4 of the Environment Code)
