Do Autonomos Need Public Liability Insurance in Spain? When It's Required (and When It Isn't)
If you're self-employed in Spain (autonomo), you'll hear 'you need liability insurance' from clients, venues, and sometimes even other expats. The truth is more specific: it's not automatically mandatory for every autonomo, but it can be required depending on your activity, licensing rules, and contracts.
Quick Answer
Public liability insurance is NOT mandatory for all autonomos in Spain. Requirements depend on your specific activity, professional regulations, and client contracts.
- No blanket legal requirement for all autonomos
- Some activities have compulsory insurance via RSO
- Client contracts often require it even when law doesn't
- Check RSO, local licences, and contracts to confirm
- Working without it when required can cost you jobs
Key Takeaways
Most autonomos are not legally required to have public liability insurance by default, but some activities are.
Requirements often come from licences, venues, professional bodies, or client contracts—not one national rule.
If you work with the public, at client premises, or run events, you're far more likely to be asked for proof.
The fastest way to confirm is to check the RSO and your local licence/contract terms.
The Short Answer
Is it mandatory for all autonomos?
No.
Spain does not impose one single "public liability insurance for every autonomo" rule. Instead, compulsory insurance is tied to specific activities (sometimes national, sometimes regional), and you can look these up in the RSO (Registro de Seguros Obligatorios).
What is common: clients, landlords, venues, and tender processes may require it contractually even when the law doesn't.
When Public Liability Insurance Can Be Required
1) Regulated Professions & Professional Bodies
Some professions (or sectors) face legal or professional requirements to hold civil/professional liability cover. In practice, this can come from the sector's regulation or from membership rules (colegios profesionales).
If your work involves regulated responsibility (health, safety, financial or technical sign-off, etc.), treat insurance as part of compliance, not as an optional add-on.
2) Municipal Licences & Public-Facing Activities
If you run an activity that needs a municipal licence (especially where the public attends), you may be asked to show liability insurance as part of permitting or venue requirements.
The exact requirements can vary by municipality and activity type, which is why the "check locally" step matters.
3) Client Contracts (the Most Common "Mandatory")
Even when the law doesn't require it, many clients will. This is especially common for:
- • Working on client property (maintenance, repairs, installations)
- • Services delivered at the client's site (cleaning, classes, events, filming)
- • B2B contracts with larger companies or property managers
If a contract says you must carry liability insurance, it's effectively mandatory for that job.
4) Subcontracting & Working with Third Parties
When you subcontract (or are subcontracted), the party hiring you often wants proof that your policy covers:
- • Your activity as stated
- • Work at third-party premises
- • Your subcontractors (or at least excludes surprises)
This is a frequent point of confusion for freelancers who "occasionally bring help."
What Happens If You Operate Without It
You Can Be Personally On the Hook
As an autonomo, your business and personal finances can be closely linked. If you cause injury or property damage to a third party and you're uninsured, you may have to handle legal defence and any settlement/court award yourself.
You May Lose Work Opportunities
In many sectors, "no insurance certificate" simply means "no contract." It's common in:
- • Property-related services
- • Events
- • Professional services with procurement rules
So even if not legally mandatory, it can be commercially mandatory.
How to Check If Your Activity Requires Compulsory Insurance
Spain's Registro de Seguros Obligatorios (RSO) exists specifically to list compulsory insurances, including the legal provision creating the obligation and whether it applies nationwide or by autonomous community.
A Practical Way to Confirm Quickly:
- 1
Check the RSO for your activity/sector and territory
This tells you if there's a legal obligation.
- 2
Ask your town hall (ayuntamiento) about licence requirements
If you need a permit for your activity.
- 3
Ask your client/venue what wording/limits they require
They often have a template.
- 4
If you're in a regulated field, ask your professional body
They'll confirm what's required.
Choosing Cover That Won't Create Problems Later
Most claims disputes happen because the insured "activity description" doesn't match reality. When you request quotes, prepare these details first:

Frequently asked questions

Is public liability insurance legally required for all autonomos in Spain?
No—there isn't one blanket rule that forces every autonomo to buy public liability insurance. Spain treats compulsory insurance as something that applies to specific activities, sometimes nationwide and sometimes by autonomous community. The official way to verify this is the Registro de Seguros Obligatorios (RSO), which lists compulsory insurances and the legal provisions behind them. If your activity isn't listed as compulsory, you may still need insurance because of contracts or venue rules, but that's a separate "required to work" situation rather than a universal legal requirement.
Which autonomos are most likely to be required to have it?
Autonomos who work with the public, on client premises, or in regulated sectors are the most likely to face an insurance requirement. This can come from licensing rules, professional bodies, or contract conditions. In many cases, the requirement is practical: a client or venue won't let you start without a certificate showing liability cover. If you do on-site services, events, construction-related work, or any role where a mistake could injure someone or damage property, expect this question early and often—and get the requirements in writing before you buy a policy.
Can a client or venue demand liability insurance even if it's not required by law?
Yes. This is extremely common in Spain, especially for B2B work, events, property-related services, and subcontracting. A client can make insurance a condition of the contract, and venues often require proof before allowing public activity on-site. The key is to match the policy to what they demand: activity description, territory, and limits. Ask for their exact certificate requirements, then request quotes that meet that wording. That avoids paying for the wrong policy and still being rejected for the job.
What's the fastest way to confirm whether my activity has compulsory insurance requirements?
Start with the Registro de Seguros Obligatorios (RSO), which is designed to list compulsory insurances by activity and territory, including the legal basis. Then cross-check with your local ayuntamiento if your activity needs a municipal licence, and check any client contracts or venue terms that might impose insurance requirements. If you're in a regulated profession, confirm with your professional body as well. Doing these three checks usually gives a clear answer in under a day and prevents you from buying cover that doesn't match your work.
