There is a lot of crime prevention advice on the internet – please look at the following sites:
Here are a few simple tips about preventing burglaries:
Many burglaries can be prevented. In 3 burglaries out of 10, the thief does not have to force his way in because a door or window has been left open. Burglars don’t like locked windows because someone may hear breaking glass. They don’t like security deadlocks on doors because they cannot open them even from the inside and they have to get out through a window.
Gates & Fences - A high wall or fence at the back of a house can put off a burglar. But keep them low at the front so a burglar can’t work unseen.
Burglar Alarms - Visible burglar alarms make burglars think twice. We can provide a list of compliant alarm companies on request.
Small Windows - Even small windows like casement windows, skylights or bathroom fanlights might need locks. A thief can get through any gap larger than a human head.
External Doors - If your front and back doors are not strong and safe, neither is your home. If your door seems weak, get another one. Doors should be made of solid core construction – 44mm thick. Glass panels on or around the door are especially vunerable, so replace them with laminated glass. (If you are a council tenant call the housing department about it.)
External Door Locks - Fit back and front doors with a five-lever mortice deadlock, to BS3621 or equivalent. A deadlock can only be opened with a key, so a thief cannot smash a nearby glass panel to open the door from the inside. If you are intending to install a PVC front door, before you buy it, check with the supplier/manufacturer that a door chain will be fitted. It can be very difficult and expensive to have a chain fitted to an existing PVC door.
Patio Doors - You should get specialist advice on fitting locks to patio doors. They should have a special lock fitted top and bottom unless fitted with a multi-locking system. Fit security mortice locks to french doors and mortice bolts to the top and bottom of both doors.
Windows - DIY shops sell inexpensive key operated locks to fit all kinds of windows. Secure the most vunerable windows first: ground floor windows, windows that can’t be seen from the street and windows that can be reached from a drainpipe or flat roof. Louvre windows are especially vulnerable because the slats can easily be removed from the frame. Glue the slats in place with an epoxy resin, better still, replace them with fixed glass. With all security, consideration must be given to the risk of fire and means of escape. Ensure you fit a smoke detector, comforming to BS5446.
Spare Keys - Never leave a spare key in a hiding place, like under a doormat or in a flowerpot – a thief will look there first.
Garages - Never leave a garage or garden shed unlocked, especially if it has a connecting door to the house. Lock tools and ladders away so that a thief cannot use them to break in.
Side Passage - Stop a thief getting to the back of the house – where he can work with less chance of being seen – by fitting a strong, high gate across the passage. If you share an alleyway with a neighbour, talk to him or her about sharing the cost.
