I've got to send a cheque for over 100k to the Inland revenue - I hasten to add it's not my money but is coming out of my late Great aunt's bank account to pay the inheritance tax.
The Halifax won't do an electronic transfer - don't ask me why - they can't tell me! Short of gettting on a train to the tax office in Nottingham (quite a long way from London), what do you think is the safest way of getting it there!
TIA
