The Risk & Regulation Advisory Council (RRAC) has been asked by the Prime Minister to encourage sensible approaches to risk management. They looked at the proposed BSI standard and were also against it. The Council also quote HSE on the matter:
The Health and Safety Executive agree that a lighter touch should be possible. HSE Chief Executive, Geoffrey Podger, said: “In 2007 HSE became concerned that uncertainty was causing some organisations to over-react to the low risk from falling trees. HSE therefore produced guidance for its inspectors on what is required by the law we enforce - the Health and Safety at Work Act 1974. It makes the point that the risk is generally extremely low. For most trees around the countryside HSE does not believe any action at all is reasonably practicable under the 1974 Act. Where trees are in very public places we suggest that non-specialist staff with a working knowledge of trees should look out for obvious problems as part of their everyday work. Inspection by tree experts is likely to be appropriate only in very limited circumstances, for example where a tree in a very public area is known to be unstable but is kept for heritage or other reasons. There are several other relevant pieces of non-HSE law; we have encouraged stakeholders to agree a simple and proportionate approach to cover all the legal duties. We hope that by sharing our own guidance we have provided a useful starting point.
