Having five decimal places seems overly precise to me. I don't think they would make such a modification.

There is a clear distinction between products that have and do not have Energy Monitoring.  Consumers pay a premium for products which have Energy Monitoring.  This implies that Energy Monitoring is a key feature, so it isn't unreasonable to expect accuracy.

If it was just my personal preference, I wouldn't have raised this request.  The prices are what they are.  In pence, they have been 3 decimal places for like ever (see attached - obtained from a gov . uk page). In £ that is 5 decimal places, so I should be able to enter £0.30295 instead of being forced to round down to £0.30 or up to £0.31.

Coding wise, it currently works and allowing additional decimal places shouldn't make a difference (From what I can tell, that field has been limited to 2 decimal places).

I am not questioning the validity of your needs but rather making a reasonable speculation about the likelihood of them accepting this suggestion. I must say, the extra information you shared is really helpful and could make a difference in getting this idea moving forward.
