UK S1 Healthcare Form Guide for Expats in Spain & Europe 2026
Learn who qualifies for a UK-issued S1 healthcare form, how to apply via NHSBSA up to 90 days before moving, how to register with Spain's INSS, and how S1 differs from GHIC and EHIC.
What is the UK S1 Form?
The S1 is a reciprocal healthcare certificate issued by the UK (NHS Overseas Healthcare Services) to prove that the UK will cover your state healthcare costs while you live in an EU country, Norway, Iceland, Liechtenstein, or Switzerland.
Who Qualifies for a UK S1 Healthcare Certificate?
S1 entitlement is determined by reciprocal social security coordination rules, not merely by citizenship. You may qualify if you fall into one of the following categories:
| Qualifying Category | 2026 Eligibility & Rules |
|---|---|
| UK State Pensioners | Receiving a UK State Pension and living in an EU country/EEA/Switzerland. |
| Exportable Benefit Recipients | Receiving certain UK benefits (e.g. contribution-based ESA, Industrial Injuries Benefit). |
| Frontier / Posted Workers | Working in the UK but living in an EU country, or posted abroad temporarily. |
| Eligible Dependants | Spouses or family members recognised as dependants by the host country's social security system. |
How to Register Your S1 Form in Spain (INSS Process)
An S1 form issued by the UK must be registered in Spain before state healthcare coverage becomes active. Follow these step-by-step INSS registration guidelines:
- Apply for S1 in the UK: Contact NHS Overseas Healthcare Services (NHSBSA) up to 90 days before moving to Spain if you receive a UK State Pension.
- Register with INSS Spain: Submit your S1 to the Instituto Nacional de la Seguridad Social (INSS) online via their portal or in person at an INSS office.
- Provide Required Documentation: Upload your S1, passport, Spanish TIE/NIE residency certificate, and Spanish healthcare application form.
- Obtain Social Security Number: INSS processes your S1 and issues a Spanish Social Security confirmation document.
- Register at Local Health Centre (Centro de Salud): Take your INSS document, NIE/TIE, and empadronamiento to your local health centre to obtain your Tarjeta Sanitaria Individual (SIP/medical card).

Frequently Asked Questions (6 Detailed FAQs)
You may be entitled to a UK-issued S1 if you live in Spain and receive a UK State Pension or certain qualifying exportable benefits. Other categories can include certain frontier workers, posted workers and eligible dependants. Eligibility depends on which country is responsible for your healthcare under reciprocal healthcare rules.
If you receive a UK State Pension and are moving to Spain, NHS Business Services Authority (NHSBSA) allows you to apply online for an S1 up to 90 days before your move once you have a Spanish address.
You must register the UK-issued S1 with the Spanish Instituto Nacional de la Seguridad Social (INSS). After processing, INSS issues a Social Security number, which you present at your local health centre (centro de salud) to obtain your medical card (tarjeta sanitaria).
A registered S1 gives access to Spanish state healthcare on the same basis as Spanish citizens. The UK reimburses Spain for your healthcare costs. An S1 does not cover private healthcare or exclude co-payments such as prescription charges.
No. An S1 establishes state healthcare entitlement in your country of residence. A GHIC or EHIC provides temporary medically necessary treatment during visits outside your country of residence.
You must inform NHS Overseas Healthcare Services and Spanish authorities of any address, pension, or family changes to ensure your S1 healthcare funding remains valid.
