Just a few snippets, which you all may find interesting, from the statutory guidance on firearms licensing to chief officers of police. https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/818022/Draft_firearms_statutory_guidance_-_16_July.pdf
2.14 All records found relating to the applicant should be recorded on the case file. This will include instances where the applicant is a victim, witness or associate rather than a suspect. Assessing the relevance and weight of any records found is covered in Chapter Three.
2.16 Home visits should include an interview to discuss any issues relevant to suitability as set out in this guidance, permit the inspection of security arrangements, and allow the firearms enquiry officer to meet any other individuals living at the address. Guidelines on security are set out in the Home Office Security Handbook.
2.43 Chief officers should carry out additional checks if, following the initial enquiries above, they believe them to be necessary to assess suitability accurately.
2.44 These checks may include, but are not limited to:
(i) checks with other agencies, such as health professionals other than the GP, social services, probation services or multi-agency groups;
(ii) checks with other licensing or regulatory bodies or enforcement agencies;
(iii) a drug or alcohol test;
(iv) credit or other financial checks;
(v) information obtained from open source social media;
(vi) interviews with individuals other than the applicant or their referees, for example, neighbours, partners or representatives of shooting clubs attended by the applicant;
(vii) background or medical checks on partners or other individuals living at, or with unsupervised access to, the applicant’s address; and
(viii) checks where there is an indication of domestic violence or abuse, as set out in paragraphs 2.45 – 2.50.
2.47 An applicant’s partner or family member is not required to give approval for the issue of the firearms certificate and this should be made clear to them. However, a request from a partner or family member that the applicant should not hold a certificate should be taken into account. The responsibility lies with the police to make the decision based on all the evidence available.
