Our suggestions
(to)/(have) access
Instead of 'access' we suggest you use:

get, get to, get into, use

As well as the usual meaning of 'access', in the sense of to get to or get into something, people now use it to mean 'use a facility' or 'be able to use a facility'.

When writing to non-experts it is better to avoid this usage.

For example, rather than talk about a group 'having access to healthcare' it is better to say 'getting the healthcare they need' or 'being able to get proper healthcare' and so on. Instead of 'having access to a bank' say 'getting to a bank' or 'able to use a bank' etc.
