In Worcester, landscape gardener Tom Conway told BBC Radio Hereford and Worcester he believed he had put up about 400 flags in the city.
“The morale in the community seemed low and, ever since we did it, people have driven past and shown nothing but love and happiness,” he said.
Mr Conway added he thought the UK should be more like the US, and fly the flag proud.
On Tuesday, Perks said climbing up lampposts and attaching flags to them “may not be the best thing to do, mostly because it’s dangerous and could cause damage”.
He suggested people could show their pride by flying the flag in their gardens, on cars, in home windows and on “community buildings where agreed by the whole community”.
He said, however, there was no specific plan to take the flags down.
