Thailand Retirement Visa for Elderly Parents: O-A Visa Explained

Everything UK families need to know about the Thai retirement visa — requirements, health insurance, costs, and the application process.

7 min read|Updated April 2026

If you're considering Thailand for retirement care, the visa is one of the first practical hurdles. The good news: Thailand actively welcomes retirees with a dedicated long-stay visa for over-50s. Here's what British families need to know.

The O-A (Long Stay) Retirement Visa

The Non-Immigrant O-A visa is Thailand's standard retirement visa. It allows you to stay in Thailand for one year, and can be renewed annually without leaving the country. You can apply at the Royal Thai Embassy in London before travelling.

Requirements

Age

50 years or older at the time of application

Financial Proof (one of the following)

  • 800,000 THB (~£18,000) deposited in a Thai bank account, or
  • Monthly income of at least 65,000 THB (~£1,500), or
  • A combination of savings and monthly income totalling 800,000 THB per year

Health Insurance

Mandatory for O-A visa holders since 2019. Minimum coverage: 40,000 THB outpatient and 400,000 THB inpatient. Must be purchased from a Thai-approved insurer. Typical cost: £1,500 – £3,000/year depending on age and pre-existing conditions.

Criminal Record Check

An ACRO police certificate from the UK, certified by the Foreign, Commonwealth & Development Office (FCDO). Processing takes approximately 10-15 working days.

Medical Certificate

A letter from your GP confirming you are fit to travel and do not have any of the prohibited diseases listed by the Thai government (leprosy, tuberculosis, elephantiasis, drug addiction, third-stage syphilis).

Passport

Valid for at least 18 months from the date of application, with at least 2 blank pages.

Application Process

  1. Gather documents — ACRO certificate, medical letter, passport photos, financial evidence, and completed application form.
  2. Book an appointment at the Royal Thai Embassy in London (or the Royal Thai Consulate in Hull for those in the north of England).
  3. Submit your application in person. The fee is approximately £50 (payable by postal order).
  4. Wait for processing — typically 5-10 working days.
  5. Collect your passport with the visa stamped inside. The visa is valid for one year from the date of entry into Thailand.

Applying for an Elderly Parent

Important: Power of Attorney

If your parent has reduced mental capacity (e.g., due to dementia), you may need to act on their behalf. Be aware that a UK Lasting Power of Attorney (LPA) is not automatically recognised in Thailand. You may need to arrange a separate Thai power of attorney, legalised through the Thai Embassy. Our team can advise on this process.

A family member can manage the visa application process, attend the embassy appointment, and handle logistics. Many of our clients have successfully arranged visas for elderly parents with our guidance.

Annual Renewal

The O-A visa is renewable annually at a Thai Immigration office without leaving the country. You'll need to provide updated financial proof and health insurance each year. There is also a requirement to report your address to immigration every 90 days (called the "90-day report") — this can be done online.

Alternative: The O-X (10-Year) Visa

For those with higher savings, the O-X visa offers a 10-year stay (5 + 5). Requirements include 3,000,000 THB (~£68,000) in a Thai bank account and an annual income of at least 1,200,000 THB (~£27,000). This is less common but avoids the annual renewal process.
