Exterior of the building

• Anti-climb paint can be applied to drainpipes. Architectural toppings or other deterrents can be attached to prevent access to low-level roofs or onto fixed ladders/fire escapes although care must be taken to prevent accidental injury. Some anti-intruder devices may only be fixed at eight feet or more above ground level. A warning sign will highlight the presence of these measures and according to the measures used, may be a requirement under the Occupiers Liability Act 1984.
• Points of entry can be numerous. Review the situation - in consultation with the Fire Brigade - and limit to as few as possible. Ensure doors, frames and locks are good, strong quality. Hinges should be concealed if possible or at least mounted on the interior side of the frame. Locks wherever possible should be mortise deadlocks to British Standard BS 3621. Old door locks can be supplemented with mortise deadlocks or internal bolts. A reputable locksmith could be consulted for advice and you will benefit from his/her expertise.
• Windows are common points of entry for criminals and regularly subject to vandalism. Ensure their protection by adding external barriers of laminated or toughened glass, polycarbonate sheeting or wire mesh grilles. Fit internal locks to windows that open. Provide curtains/blinds to conceal contents.
• Exterior lighting is an excellent and relatively inexpensive deterrent. Electronic timers, photoelectric switches and automatic detectors are readily available. Care must be taken in fixing both lights and sensors so that they are not accessible to damage. Low voltage photoelectric ‘dusk to dawn’ bulkhead lights are recommended. High-energy consumption halogen PIR floodlights (commonly sold as ‘security lights’) are not recommended for security.
• Consider CCTV.
• Whenever fitting or replacing new locks, doors, windows, glass, alarms etcetera always use the recommended British or European Standard. If in doubt, ask your local Crime Reduction Officer whose service is free.
