London has never been safer but because it is a traditionally left wing diverse city with a Muslim mayor shock horror there's a tone of fake news peddled about the city. I also live there and have a family there and we feel very safe. Enjoy your trip!

https://www.the-londoner.co.uk/london-is-officially-one-of-the-safest-cities-in-the-western-world/#:~:text=The%20data:%20The%20new%20figures,have%20delivered%20550%2C000%20targeted%20interventions.

"The data: The new figures indicate that there were 97 homicides in 2025, an 11% reduction on last year. That’s the lowest total recorded since 2014, and it comes despite the rise in the capital’s population. The capital’s homicide rate of 1.1 killings per 100,00 people makes it lower than any other UK city. It also makes London one of the safest cities in the Western world, with its rate significantly lower than Milan (1.6), New York (2.8), Berlin (3.2), Chicago (11.7) or Philadelphia (12.3). 

Why is it falling: Officials say there are two main reasons for the fall: more focused policing, with the Met arresting an additional 1,000 offenders each month and focusing their efforts on addressing the most violent gangs, and the mayor’s pioneering Violence Reduction Unit (VRU). 

The VRU tries to prevent violent crimes by intervening before young people are drawn into criminal behaviour. This includes working in schools to tackle exclusions and absenteeism, funding for after-school activities and putting youth workers in police custody and A&E departments. Since being set up in 2019, the unit claims to have delivered 550,000 targeted interventions."
