Other consular services
Notarial and documentary services
For legal reasons, they are unable to carry out notarial acts in Commonwealth countries. This includes certifying documents as true copies of originals, administering oaths or taking affidavits. For these or other notarial acts, you should contact a local notary.
As Bangladesh is a Commonwealth country the British High Commission is not empowered to offer notarial services. They do not issue Visa Recommendation Letters to British nationals, visit: https://www.gov.uk/government/publications/visa-recommendation-letters-information-note--3
They charge fees for some of their services. See the full list of consular fees in Bangladesh, here: https://www.gov.uk/government/publications/bangladesh-consular-fees
