I was wondering where the law stands with razor wire. I have received conflicting advice and would appreciate your help. JB, by e-mail

A. The law is not clear on this, and it can be difficult to get definitive advice. Most of my inquiries led me to the Home Office, but a spokesman told me he was unable to help. The Association of Chief Police Officers advises against the use of barbed wire, razor wire, wall spikes or broken glass on the grounds that building owners have a duty of care to ensure that visitors to the property are reasonably safe.
This may sound crazy, but that duty extends to trespassers and intruders, and anyone who injures himself on your property may be able to take out a civil action against you.
On a more reasonable note, a serving police officer has pointed out to me that the police in pursuit of a suspect could themselves be injured on the wire, and might therefore consider suing.
However, manufacturers of these products tell me there is no specific legislation that forbids their use, as long as the wire is installed with reasonable precautions. This means that a material such as razor wire should be clearly visible, and not positioned in such a way that it could act as a man-trap. It should therefore either be up high, on top of a fence, wall, or roof, or else protected by an outer fence.
In other words, it should not be possible for an unsuspecting, innocent party to come into contact with it accidentally. It should also be clearly signed with yellow warning triangles that say "Razor barb - Danger" or "Warning - Barbed wire". Proof of adequate signage should provide a good defence in the event of a civil action from an injured trespasser.
Signs should be provided by the manufacturer, or can be obtained from BBT Ltd (01299 251 770 www.birminghambarbedtape.co.uk), which also makes alternative, "less aggressive" intruder deterrents such as Tangle Wire.
Finally, note that any security measure of this nature might be subject to planning or building control regulations, and to be on the safe side you should consult your local authority, as different local authorities have been known to interpret the regulations in different ways. It is generally permissible to build a boundary wall or fence up to two metres high unless it is within one metre of a highway, in which case the limit is one metre high
