Can I combine funds from a Thai bank and a UK bank for a Non Imm O-A Retirement Visa application?

The following is taken from the UK Thai Embassy website in relation to applying for a Non Imm O-A Retirement Visa

“Bank statement or evidence of adequate finance for the past 3 months showing a deposit of the amount equal to and not less than 800,000 Baht (approximately £20,000.00) If you send a copy of bank statement, the original reference letter from the banking concerned is necessary”

This is now my main option for me to return to Thailand in the summer as it’s the Visa most people recommend.

My question is were do these funds need to be, I have some in a Thai bank and some in a UK Bank, if both sets of statements add up to over THB800,000 will that be ok or if not which country do they need to be in.

Thank you 🙏🙏
