There is no harm, many European  cities and countries like Stockholm, few German cities, spain, Brussels allowed Adhan on loudspeakers even in chaina and many western countries 

There are around 1750 masjid in the uk

In part of Europe church bells and mosque"s call to prayer sound in solidarity during covid.

We believe its the right time to experiment and allow highly muslim populated areas with a loud call for prayer atleast 3 to 4 times a day not during anti-social hours.

The adhan, or Islamic call to prayer, is an integral part of the Muslim faith. The number of people practicing the religion of Islam in the United Kingdom exceeds around 3  million. Some neighborhood towns have more than 50% to 60% Muslim population

Britain is a country with a proud history of upholding the values of faith, and of recognising the principle of freedom of religious observance for all citizens.

 We aware The Government recognises the unique contribution that people of faith make to their own local communities and to wider society. Britain’s religious and racial diversity strengthens and enriches our society. Freedom of religious observance for all citizens is an important principle of a free society.
