MaintainlyHow often must a gas installation be inspected in Spain?
Gas installation inspection every 5 years. The commonly recommended range is every 5 years. Leaks and badly vented appliances cause fires and carbon monoxide poisoning, and the check is compulsory. This is a safety-critical task, so do not let it slip.
Spanish homes with a piped gas supply must have the installation inspected every five years under Royal Decree 919/2006. The gas distributor writes to you three months ahead. You can have an authorised gas installer do the inspection and send in the certificate, or leave it to the distributor, which then gives you at least five days’ notice of the visit. It is different from the boiler service, which is due every two years for wall-mounted gas boilers up to 70 kW in homes.
Why does a gas installation inspection matter?
Leaks and badly vented appliances cause fires and carbon monoxide poisoning, and the check is compulsory.
What happens if you skip a gas installation inspection?
Leaks and badly vented appliances cause fires and carbon monoxide poisoning. If the inspection finds a serious defect that cannot be fixed on the spot, the supply is cut and the affected part or appliance is sealed until it is repaired. The Basque consumer agency Kontsumobide warns that skipping the inspection can lead to the supply being suspended.
What does the professional actually do?
- Checks the installation for leaks
- Sorts any defects into main ones, which stop the supply, and secondary ones, which you must have corrected
- Issues a certificate, or a report of the defects to correct
How do you choose someone qualified?
Wait for the letter from your distributor and ask to see the inspector’s identification. When the distributor does the inspection, the regulated fee is charged through your gas bill, so do not pay anyone at the door. If you prefer your own authorised installer, the certificate must reach the distributor by the date in the letter.
What do people get wrong?
- Letting in an unannounced “inspector” who was not sent by the distributor or chosen by you
- Paying cash at the door for an inspection that is billed through the gas bill
- Blocking ventilation grilles to keep out draughts: gas appliances need that air
- Confusing this inspection with the boiler service, which is a separate duty
When should you stop and call someone?
Always, and immediately if you smell gas: leave the home and call the distributor’s emergency number.
Does this differ in the US, UK, Australia or Canada?
United States
There is no national routine inspection of the home gas installation. If you smell gas, leave and call your gas utility.
United Kingdom
Owner-occupiers have no legal inspection duty. Landlords must have a registered engineer carry out a gas safety check every year on each appliance and flue.
Australia
There is no routine inspection for owners. In Victoria, rental providers must arrange a gas safety check every 2 years for agreements made after 29 March 2021.
Canada
There is no routine inspection for owners. Gas work should be done by a licensed technician.
What about in Europe?
Spain
Periodic inspection of piped gas installations every 5 years, by the distributor or an authorised installer you choose. Installations not fed from a network, such as bottled LPG, need a review every 5 years that you arrange with a gas installer. Wall-mounted gas boilers up to 70 kW in homes also need a service every 2 years, including in the País Vasco.
