The UK’s capital and one of the world’s most desirable cities in which to live, London is home to over eight million people.

With such a large population living together in a relatively small space, it’s no surprise that crime rates in London are high when compared to the rest of the country.

Knife crime is of particular concern in the capital, with 1,749 stabbings of people aged under 25 recorded in August 2016 alone.

The most serious areas for crime are among the most affluent, with Westminster, Kensington and Chelsea and Hammersmith and Fulham all placing high for average burglary and robbery rates.

On average, the London Fire Brigade gets called out to 13 house fires per month in the city, with Wandsworth, Haringey and Enfield the worst-hit boroughs.

At Phaseone, we offer security services – as well as cleaning and property maintenance – in London. Get in touch with us to make your home safer today.
