To extend for another 30 days you simply go to the local immigration office in Thailand with copies of various things, complete a form and pay the fee.
Make sure the accommodation where you are staying register you with immigration when you arrive.
If you leave the country after our extension ends then you could enter immediately and get another 30 days Visa Exempt, which again can be extended for another 30 days.
You will get immediate access to NHS treatment once you have a U.K. address and say you have returned permanently. Health is devolved so organisation is different in England, Wales, Scotland and N Ireland.
First step wherever you are is to register with a GP, which should be easy.
After that it depends where you are. The system is pretty much on its knees after years of chronic underfunding but it does vary in different parts of each country. You’ll need to check the situation in the area you intend to live.
If you ever need Social Care the situation is even worse. The elderly are warehoused and treated abysmally in many parts of the country. There can be waits of a year or more for home carers to allow people to go out of hospital.
There is no link between NI contributions and NHS treatment. It is a residence based system. The NI contributions only decide how much state pension you have.
You get an annual extension, so 12 months at the end of the 3 months then 12 months annually from there. You need to have the stated cash in a Thai bank account (or use an agent). You can get a Multiple Reentry permit which allows you to come and go when you like during the 12 months.
There are different ways of doing it but I would suggest you each get a Non O on the basis of being over 50 from the Embassy in London before you travel. You apply online and you get an e-visa.
This will give you 90 days on arrival in Thailand.
If you’re not sure about accommodation just book hotel or short stay in condo to look around. Don’t commit to long term rent until you’ve tried different areas/buildings.
You can open a bank account each when you arrive. They’ve got more strict so you might need to use an agent just to get your accounts. It should cost just under 4000 baht each.
You’ll need to transfer at least

0 baht into each account in order to get your annual extension of stay.
It needs to stay above 800k for 3 months afterwards and can’t drop below 400k thereafter. It needs to be back up to 800k at least 2 months before the following year’s extension.
It might be easier just to leave the 800k in each account.
You’d have to leave the country after the initial visa ended to ‘kill it’. You then have to start again with a Non O. It is possible to enter on a Tourist Visa, or even on Visa Exempt, and then convert to a Non O in Thailand but it can be a bit of a hassle. If you’re sure you are retiring to Thailand then IMHO it’s best just to start with the Non O. It’s not difficult to get the annual extensions. That’s assuming you have 800k baht each to put in a Thai bank account and leave there. If you start with a Non O-A and just want to stay then you need health insurance with a Thai company each time and it’s not worth it.
As you are over 50 and want to stay a year then probably best to apply for a Non O-A visa from the Thai Embassy in London. It’s all online now. It does require a police check, a medical form and health insurance but you’ll get a year on entry.
If you think you might want to stay more than a year then the Non O ‘for Retirement’ might be better BUT you’ll need to have

0 baht in a Thai bank account for you to get a year Extension after the initial 90 days the visa gives you.
