Security tips

Window Locks
There are special locks and bolts designed for wooden casement and sash windows. Some can be locked but still be opened a certain amount for ventilation - ideal for a child's bedroom. Fit at least two locks or bolts to each medium to large opening window frame so that it cannot be prised open.

If you have plastic frames, the windows should have locks built into the assembled frame. If these don't seem secure enough, contact the makers to ask if extra locks can be fitted.

Check you have enough window lock keys for each room and keep the keys in a handy place.

Tip: Use the biggest screws possible to fit the locks, even if it means throwing away the screws provided in the pack.

Sheds
Burglars will often use tools from a garden shed to force windows and doors, so make sure any outbuildings have strong padlocks and doors. Replace any vulnerable exterior screws e.g. on shed or side-gate padlocks, with long clutch head screws that cannot be removed after fitting - these are available at hardware shops.

Outside the House
Check that side fences are secure and reinforce them with concrete posts if necessary.

Add a light with a PIR detector at least 2.5m (2.7yds) above ground level to cover the area around the house.

Planting prickly shrubs like firethorn, barberry and mahonia is a real deterrent. Gravel on paths and patios allow you to hear footsteps.

Doors
Doors can also be given extra protection. In addition to a good quality door lock, consider fitting extra hinge bolts, a door chain and a peephole viewer to improve security.

For vulnerable flat doors, specially shaped metal strips are available for adding to the strength of a door. These run from the top to the bottom of the door and also reinforce the frame.

Replace standard glass back door panels that could be at risk with laminated glass that is virtually impossible to smash.

Tip: The door will only be as good as its frame - replace it or repair it if it is rotten or loose.

French Windows and Patio Doors
French windows can be a weak point because their frames are often too thin to fit a mortise lock.

Start by adding flush-fitting rack bolts that lock into the top and bottom of the frame. Before buying a central lock, check that it can be used on outward-opening doors. In high risk areas, it may be worth adding foldaway metal security grilles as well.

Upgrade metal-framed patio doors with surface-mounted locks to stop burglars prising the sliding glass sections out of the rails.

Extra Precautions
If you have just moved into a house, it's worth changing the locks on all the exterior doors so you know exactly who has keys for your home (see Secure It for more tips.) You can save money by just replacing the cylinder of a rim lock.

Contact your CPO (Crime Prevention Officer) through your local police station for extra advice on home security, and ask if there is a local Neighbourhood Watch scheme you can join. For more information, log on to the Master Locksmiths Association.
