Hi Ed and welcome!
In addition to the HUBB, there is quite a lot of information available on the website, including experience from actual travellers who have shipped into various locations.
I expect you will have to ship into Bangkok rather than Phuket, and I suggest your first stop should be Thai Air Cargo. From their website, their office is:
c/o Menzies World Cargo,
Shoreham Road West,
Heathrow Airport,
Hounslow, Middlesex TW6 3RT
Telephone: 020 8564 0190
Fax: 020 8897 1283
If they won't deal with you directly, they will be able to advise you of an agent. Also, try British Airways cargo.

Although we don't have any reports of shipping from the UK to Thailand, numerous people have shipped into Bangkok from India or Nepal, so there are lots of descriptions of the Thai entry process on the Shipments by Travellers page. See for example:

Bottom line is - plan to spend about a day in Thailand dealing with paperwork and customs.
As for the Carnet de Passage, Thailand neither requires nor accepts the Carnet. Although some travellers have used their Carnet, this was due to inexperience of customs officers at a particular border. Thailand is NOT a member country of the carnet association, and if your only destination in the region is Thailand, it would be a waste of money to obtain a Carnet. Since you say you wish to travel in the region, you can obtain a Carnet from the RAC in the UK. You can't reach the carnet department via their website, but Sean Kelly advises: "Speak to the wonderfully helpful Sue Collins 01454 208000 ext 33837."
Instead, Thai Customs may stamp the vehicle details in your passport so you can't leave the country without the bike. Or, they may issue a temporary import permit but require payment of a deposit to cover duty and taxes. This permit is valid for 30 days from date of entry, but should be able to be renewed if you have a visa. Limit might be 6 months, though, after which leaving the country and re-entering may allow a new permit.
You'll note a lot of 'mays' here. Unfortunately, it is difficult to get a definitive answer to the question of exactly what paperwork is required. Your situation is also more complex, since you will actually be working and residing in the country. I would start with the Thai Embassy in London, but make an anonymous inquiry or one under a fake name. That way, if you don't like their answer, at least you're not on record as having asked the question
When you get to Thailand, be sure to contact or join the Horizons Unlimited motorcycle travellers community in Bangkok.
