London is a safe city. Violent crime is not as prevalent here as it is in other travel destinations, most likely due to the general lack of guns on the street (although the number of illegal guns in the UK has risen over the past few years). Few police carry guns, though you may well see armed police at airports, main railway and underground stations, government buildings and embassies, especially so if there could be a terrorist threat.

Crime here is more likely to be of the thieving kind – pick pockets and bag-snatching – than it is to be of the violent kind so you should not ruin your vacation by obsessing over it. Beware of card trap devices attached to ATM's and where possible use machines inside Bank lobbies. Also beware of being distracted whilst using ATM's. Do not be tempted to change money to a guy in the street offering a good deal. You WILL lose out.

Also, as is the case in any large city, there will be people claiming to represent all sorts of different events and charities and they will look very authentic. Some of them probably are but its always best to just avoid these people as you have really no idea where your money is really going. If you are ever asked for any more money than you may be willing to give, just say "That's all the change I have" and walk away.

You should use common sense and keep aware of your surroundings. Be careful not to flash around large amounts of money or expensive possessions such as mobile phones.

Incidents of crime on public transport in London do exist, but are very rare. The London Underground network is one of the safest to ride in the world, and is an excellent means of transport for you in the evening until service ends at about 00:30. Every station is staffed at all times. While on the Tube, you will frequently see signs and hear announcements asking you to please report any unattended bag that you see on a train. The staff at the stations take this vey seriously due to the terrorist threat and will thank you heartily for reporting anything abnormal. They will NEVER not take you seriously and you will NOT get into trouble at all if it turns out to be nothing which, it likely will be.

If the tube does not travel to your destination, or it is too late, a comprehensive night bus network operates throughout the city. Transport for London does issue some advice about the use of minicabs;  Never use an unlicensed minicab and never accept a ride in the street from someone claiming to be a minicab driver, they must be pre-booked. However, this should not entirely deter you from using one of London's famous black cabs if need be. The drivers are generally very honest and pleasant to talk to. Also, if they think you are within easy walking distance of where you asked them to take you or if they think there is a cheaper alternative means of transport there, they will tell you right up front before you even climb into the cab.

Solo women travellers should not experience any distinct difference in treatment from any other tourist. It would be advisable for any single tourist not to take an illegal minicab for their own peace of mind. You should not worry untowardly about travelling alone.

If you do find that you need the police, fire brigade or an ambulance in an emergency, dial 999 or 112 from any land-line or mobile. Police Stations are located throughout the city and have alternative non-emergency phone numbers.

You should be aware that although not as dangerous as most big cities in the USA, there are sometimes reports of knifings, assaults, rapes and theft. Do not underestimate the potential for crime or violence, especially after dark. According to many reports there also seems to be a growing tendency among some youth to travel in gangs and even though they may normally be harmless, it can be very intimidating, especially if you are alone. Alcohol abuse seems to be a main cause of much of what is referred to as anti-social behaviour, so be wary in clubs and also in other places where alcohol is served.
