Do you need health insurance for a Thailand Non-O-A retirement visa from the UK? Yes. Unlike the ordinary short-stay Non-O retirement route, the Non-Immigrant O-A (Long Stay) visa has specific compulsory health insurance requirements, along with medical and police-clearance requirements.
British applicants aged 50 or over often come across the Non-O, Non-O-A and Non-O-X visas when researching retirement in Thailand.
Although their names look similar, the application documents, insurance requirements and periods of stay differ.
This guide explains the Non-O-A retirement route using the Royal Thai Embassy in London's published requirements.

1. What Is the Thailand Non-O-A Retirement Visa?
The Thailand Non-Immigrant O-A visa is intended for qualifying applicants aged 50 or over who want to spend an extended period in Thailand for retirement.
The visa is intended for retirement purposes and does not provide permission to work in Thailand.
The Royal Thai Embassy in London describes the Non-O-A as a one-year, multiple-entry visa.
An eligible visa holder may receive permission to stay for up to one year on entry, subject to immigration rules and the validity of their qualifying health insurance.
This differs from the initial Non-O retirement visa, which generally permits an initial stay of up to 90 days.
An eligible Non-O holder may subsequently apply for a separate one-year retirement extension in Thailand.
It is important to distinguish between the validity of a visa and the permitted period of stay granted by Thai Immigration.
2. Do You Need Health Insurance for a Non-O-A Visa?
Yes. Health insurance is compulsory for the Non-O-A retirement visa category.
The Royal Thai Embassy in London requires insurance from an acceptable Thai or foreign insurer covering general illness, including COVID-19.
The published minimum cover is US$100,000 or ฿3,000,000.
The duration of permission to stay can correspond to the period covered by the qualifying insurance.
Important: Do not assume ordinary travel insurance, NHS entitlement or a policy with a large headline medical benefit automatically meets the Thai Non-O-A requirements.
The insurer must provide the necessary coverage and supporting certification required by the authorities.
Can I Use UK or International Health Insurance?
Potentially, yes. The London Embassy permits qualifying Thai or foreign insurance.
However, foreign insurers must provide the prescribed Foreign Insurance Certificate where required.
This certificate must be properly completed, signed and stamped by the insurer.
If your insurer cannot provide the required documentation, your policy may not be accepted.
Before purchasing insurance, check the Royal Thai Embassy's retirement visa rules and Thai long-stay insurance information .
What Happens If I Cannot Obtain Qualifying Insurance?
Applicants should not assume that medical conditions, personal savings or an ordinary travel policy automatically remove the insurance requirement.
Some immigration arrangements may provide alternatives for specific circumstances, but these are subject to separate rules and evidence.
Applicants should obtain confirmation of the requirements applicable to their circumstances before submitting an application.
3. What Documents Do UK Non-O-A Applicants Need?
The Royal Thai Embassy in London publishes a category-specific document checklist for Non-O-A retirement applications.
The principal requirements include the following.
Passport and Photograph
A valid passport and recent applicant photograph meeting the required specifications.
UK Residence Evidence
Proof of residence within the Embassy's jurisdiction, including relevant immigration status documents where applicable.
Financial Evidence
Acceptable bank statements, income evidence or other financial documentation meeting the published requirements.
Medical Certificate
A medical certificate addressing the diseases specified by the applicable Thai requirements.
Police Clearance
Appropriate criminal-record clearance. For UK applicants, the Embassy specifies ACRO police clearance.
Health Insurance
Proof of qualifying health insurance and any required insurance certificate.
What Are the Financial Requirements?
The London Embassy publishes two principal financial routes for the Non-O-A application:
- Qualifying monthly income of at least ฿65,000.
- Evidence of funds of at least ฿800,000.
The supporting documents must satisfy the Embassy's current requirements.
Exchange rates change, so UK applicants should not rely on outdated sterling conversions found in older articles or social media.
These are the financial eligibility requirements for the Non-O-A visa, not the price of a professional visa service.
Medical and Police Certificates
According to the Embassy's published requirements:
- The medical certificate must be no more than three months old.
- The relevant UK police clearance must be no more than six months old.
Applicants should arrange these documents carefully to avoid them becoming outdated before submission.
4. How Do You Apply for a Non-O-A Visa from the UK?
- Check eligibility. Confirm that you meet the minimum age, retirement and financial requirements.
- Check health insurance. Confirm that the proposed policy meets the required cover and certification rules.
- Prepare supporting documents. Arrange the required passport, financial, residence, medical and police evidence.
- Apply online. Visit the official Thai e-Visa website and select the correct visa category.
- Upload documents and pay. Submit the supporting evidence and pay the applicable official visa fee.
- Wait for the decision. Monitor your email for additional document requests, an interview invitation or the visa decision.
Applicants using the Royal Thai Embassy in London must meet its application jurisdiction requirements.
The Embassy's general guidance recommends applying approximately 6–8 weeks before travel.
Its general instructions also advise against applying earlier than 90 days before the intended arrival.

5. Non-O-A vs Standard Non-O Retirement Visa
Both categories may be relevant to UK residents planning retirement in Thailand, but they have different requirements.
| Requirement | Non-O-A Visa | Standard Non-O Visa |
|---|---|---|
| Minimum age | 50 or over | 50 or over for the retirement category, subject to applicable eligibility rules |
| Initial stay | Potentially up to one year | Generally up to 90 days |
| Entries | Multiple entry | Usually single entry for the initial retirement visa |
| Health insurance | Compulsory qualifying insurance | Different requirements; the Non-O-A insurance certificate rules should not automatically be applied |
| Medical certificate | Required under the published O-A checklist | Not generally part of the same initial Non-O checklist |
| Police clearance | Required under the published O-A checklist | Not generally part of the same initial Non-O checklist |
| Longer stay | Subject to Thai Immigration extension requirements | Eligible applicants may apply separately for a one-year retirement extension |

This guide explains Non-O-A requirements; it does not mean that Non-O-A applications or insurance policies are included in our standard Non-O package.
6. What Happens When Your Non-O-A Stay Is Due to Expire?
A Non-O-A visa does not provide permission to remain in Thailand indefinitely.
If you wish to remain beyond the period granted, you must establish whether you qualify for an extension under the applicable Thai Immigration rules.
These may include financial, insurance and reporting requirements.
Non-O-A visa holders should confirm the continuing insurance requirements when seeking extensions.
Long-stay foreign nationals may also need to submit 90-day address reports.
Remember that a re-entry permit does not itself extend the expiration date of your existing permission to stay.
7. Non-O-A Visa FAQs for UK Applicants

No assumption should be made that NHS entitlement meets the Embassy's specific health insurance requirements.
Applicants must demonstrate qualifying insurance using the required supporting documents.
Is a Non-O-A Visa the Same as a Non-O Visa?

Potentially, if the policy satisfies the required coverage and the insurer provides the prescribed Foreign Insurance Certificate.
