Rare
Under 5% of wildlife watchers report a Common Copperback sighting in London on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 673rd most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and August
In those months about 10% of wildlife watchers report a Common Copperback in London on a given day, against under 5% in June–July and September–April, the lowest months.

GBIF citizen-science records
It is estimated from how often the Common Copperback is recorded against all the insects logged in London (25 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
