One aspect to be considered when forcing an entry (particularly to domestic premises) is who is going to secure the premises.
For commercial, most AFD monitoring stations will call a keyholder. Or if you are very lucky, the Police or perhaps mobile security firm may be able to help.
This is never the case with domestic. The Met are reluctant enough to babysit a commercial premise let alone a domestic one & who can blame them). This leaves the OIC in yet another quandry. (in the words of the Rolling Stones:) Do I say or do I go?
The LFB have a policy that once a keyholder is requested, the Brigade stay on scene for at least 1 hr to exercise their 'duty of care'. Then the premises are left insecure and unattended. The OIC tells control by radio, who I assume tell the met. Then it's open house time for burglars (especially those with listening posts)
