What areas would not be included?
Location of the job. This is flexible working (ie start finish times). This is not about the location of the job. Therefore remote working would not be included, as this is a location not flexibility. The same as if your allocated to the Manchester branch, this would not change to being based in the chester branch a day week. Again, that is location ad a different subject
Home working or hybrid is not included, this is not flexible this is place of work. See our guide about hybrid/remote/remoteonly working. Offering flexible working means the days, the start times, finish times, the breaks etc etc. If you have a hybrid option, you still need a flexible request to change any hours etc. For many companies who offer hybrid, the expectation is you still clock on and off at the same time and you have a suitable space to work in. You would still require child care for example with hybrid, so if this is a issue, you will need a flexible request about the finishing times.
Changing the opening hours of the business is also not included. If the company is Mon-Fri, you can not ask for a wednesday off ad work a saturday if the business is closed on a Saturday.
