Churches sometimes need to consider "rearranging their furniture" in order to make things easier to use, or more accessible, or more appropriate for a new activity or for an existing activity done in a new way.

This rearranging is called, in church terminology, "re-ordering" and Churches have done this for centuries. For example, the pews in your church were probably put in during the 18th or 19th century (during the middle ages churches didn't have pews!) And when they were put in, there were subsidies/grants from national bodies for free seats for poorer people (rich people had reserved seats for which they paid pew rents) which created an unhelpful incentive to cram as many pews as possible into a church: so many churches are now removing some pews to make space, because a sense of space is conducive to worship.

One particular problem most churches face is that all or nearly all the furniture is fixed - making moving it a more major and complex project, which would be difficult to undo again.

Re-ordering usually requires a Faculty, but if the re-ordering is genuinely reversible (e.g. you are trying something out) the Archdeacon can grant a Licence for a Temporary Reordering, which can last for up to 15 months after which a Faculty must have been granted or things replaced as they were before.
