Not a new problem - I have long thought that the education of bankers is seriously lacking in many respects.
To add what seems to be a new thread, when in practice I normally used copies certified in accordance with s3 of Powers of Attorney Act 1971, and found these acceptable to National Savings, Land Registry, stockbrokers/registrars, and most banks/building societies. Admittedly, there are always some clerks who will be difficult, normally out of ignorance, but can/should we gravitate to the lowest common denominator, as I fear our conveyancing colleagues have done?
To those unfamiliar with the PoAA1971, s3 basically requires a certificate at the foot of each page and a further certificate on the last page. My secretaries found it routine to print a certificate onto a photocopied page [reduced size if needed] and then copy as required. Dates weren’t mentioned, but could easily be added if desired - leaving merely the “pain” of signing multiple times - and am I the only one to remember signing/countersigning multiple cheques on client/office accounts?
In response to Kathy, I suspect that Legal Executives were added in 2007, but confess I have not checked that point.
