A Bacs payment takes three days to arrive and is only sent on business days. The Bacs cycle starts with a file submission, which has to be submitted up until a certain cutoff time, this gets sent on the third business day.
A Bacs transfer normally arrives very early in the morning on the third day, usually by about 7am. Beware, this can only happen Monday to Friday, even though it is an electronic payment system it takes non-working days off.

Bank to bank payments can also be made through CHAPS and Faster Payments. CHAPS are same day payments for high value transfers which cost about 20-30 pounds per transfer. Faster Payments are payments that usually clear in seconds, up to the value of 250,000 pounds per transfer, and are much cheaper than CHAPS.
If you want to make really fast payments to suppliers and employees then you need Telleroo. Payments arrive in payee bank accounts in seconds.
