The only criteria that the UK government issues to travellers for financial documents is very broad:
- Other documents you may want to provide ā all visitors
This section provides guidance on the types of documents that you may want to provide to help us consider your application against the Immigration Rules.
- ...
- financial documents showing that you have sufficient funds available. These must clearly show that you have access to the funds, such as: bank statements
The guidance documents issued by the UK Home Office for visit visas also does not mention anything specific about financial supporting documents.
Your application will be judged on its merit - UK immigration deals with bank statements and other financial statements from an extremely diverse range of sources and will have means at their disposal to evaluate their accuracy and authenticity as a result.
I see no reason why documents from a specific bank would not be accepted so long as they pass the desired scrutiny.
