You asked

​I would like to know the number of people in the U.K that don't have an instant access savings account please?

The data will be fine if you can show the people that do, or the likely total number of accounts if this isn't possible.

Any time period would be useful but preferably within the last two years.

We said

The Wealth and Assets survey (WAS) is a Great Britain level. Statistics for Northern Ireland can be obtained from the Northern Ireland Statistics and Research Agency (NISRA).

We do not hold data on the numbers of people with instant access savings accounts. The WAS questionnaire, and therefore data collected, does not currently differentiate between types of savings account (such as how easily the funds can be accessed).

Our most recent estimates of amounts held, and number of people with any savings account can be found in table 5.1 here:
