If it’s in your contract then yes but if you were hired to work in an office but allowed to WFH for some time because of company policy I doubt it would be seen as such even in the UK

At some point it becomes custom and practice, particularly in a case like this where they've pledged it would be permanent.

think of WFH more like a defacto relationship.
