Wat Phra Sri Sanphet was a Royal Buddhist Temple located on the site of the old Royal Palace in Thailand's ancient capital of Ayutthaya. Wat Phra Sri Sanphet UK was founded to revive the history and honour the Chief Buddha Statue known as Phra Sri Sanphet enshrined within the main Temple of Wat Mahathatyuwaratrangsarit, a Royal Monastery in Bangkok where Ven. PM Bhatsakorn is an affiliate and assistant to the abbot.  

The history of Wat Phra Sri Sanphet UK began in 2006 when Phrarajawithetpanyakhun or Dr. Phramaha Laow Panyasiri the then abbot of Wat Buddhavihara in Ashton Birmingham, held meditation sessions in Bristol and created the Theravada Buddhist Centre before handing it over to Ven. Phramaha Bhatsakorn Piyobhaso. In order to raise funds for the construction of a permanent temple in south-west England, from 2007 until 2016 Ven. Phramaha Bhatsakorn Piyobhaso with the support of the local Thai Buddhist community, hosted two major events each year: Songkran Festival (Thai New Year) in April and Loy Krathong Festival (Flower Floating) in November. With the support of local Thais, their partners and friends, the organization of festivals improved and the income from the events increased dramatically. This gave the confidence that the establishment of a permanent Buddhist Temple in south-west of England was possible. To achieve this goal, in January 2017 the founding trustees formed the Thai Buddhist South West Trust, which was registered with the Charity Commission and controlled by a Trust deed under charity number 1171258. 

The first step in the establishment of a permanent Buddhist Temple was to rent a property at 5 Satchfield Crescent in Henbury, Bristol. This property was used to accommodate the first monks to come from Thailand and to hold small events. After 12 months, the Trust then rented another property at 12 Cloverlea Road, Warmley. It was at this time the Trust commenced looking to purchase a property in order to establish a permanent location for a temple.
