The British government earlier asked if its police could observe the probe.
The team comprises a Metropolitan Police Detective Chief Inspector from the homicide and major crime unit, a forensic operations coordinator from the Met, and an experienced homicide detective from Norfolk police.
They may offer additional assistance if requested by Thai authorities.
Meanwhile, the parents of the two Myanmar men accused of murdering British tourists Hannah Witheridge and David Miller on Koh Tao last month are due to meet their sons in the prison on Koh Samui today (October 24).
Human rights advocate Surapong Kongchantuk said the parents will be accompanied by officials from the Myanmar embassy and a team of lawyers from the Lawyers’ Council of Thailand. Mr Surapong is also head of the council’s human rights subcommittee on ethnic minorities.
The embassy was comfortable working with the council as it was a neutral organisation and not affiliated to the police, he said.
Mr Surapong said a representative of the Myanmar embassy expressed his concern over the case in talks on Wednesday in Bangkok.
The ambassador told him the murder case has affected the three countries involved, he said.
Britain had lost two citizens, while Thailand’s tourism industry has been hurt, and so has the image of Myanmar, Mr Surapong said.
Suspects Zaw Lin and Win Zaw Htun initially confessed but have since recanted their confessions, claiming they were tortured into admitting to the crimes.
Prosecutors say they will press ahead regardless.
Mr Surapong said prosecutors may request another investigation by a new team if they find too many holes in the current police probe.
At this stage, he added, any new evidence could be added to the case if prosecutors find it to be valid.
