Just to close this off. The arson attack investigation is still ongoing and not much hope of a successful outcome now. So another unresolved crime on the books for the local Police.
But the important bit about this post. Here is the response I received from the HSE. Didn't take the 30 days but it is very wishy washy
Thank you for contacting the Health and Safety Executive (HSE) with your enquiry regarding RIDDOR 2013. The information you require can be found on our website along with further comprehensive health and safety guidance and information.
For the incident to be reportable it would need to meet the criteria set out in the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 for a Dangerous Occurrence.
From the information provided in your enquiry it would appear that this incident is not reportable. However, ultimately
the decision on whether to report in line with current RIDDOR 2013
requirements lies with the nominated responsible person within the
organisation as they have all the pertinent facts; HSE is not in a position to make the decision for you.
HSE’s
role requires us to ensure that duty holders comply with legislation,
however we do not prescribe in detail how that is achieved. Because
every undertaking is unique and diverse the onus is on the duty holder
to ensure that they comply with current legislation.
HSE
is only able to provide generic information on health and safety issues
and cannot give specific advice on individual cases, as the
circumstances of each individual situation will be different. Any views
given by us on the interpretation of the Regulations represent our best
judgement at the time, based on the information available. Ultimately,
only the courts can give an authoritative interpretation of the law when
considering the application of the Health & Safety at Work etc Act
1974 and the Management of Health and Safety at Work Regulations 1999.
Accordingly we would always advise you to seek the views of your own
professional advisors.
Please
be aware that HSE is not permitted to offer a health and safety
consultancy service. If you feel you need to engage the services of a
health and safety consultant you may wish to visit the Occupational Safety and Health Consultants Register (OSCHR), which provides information about qualified health and safety consultants.
Yours sincerely,

Seems strange that the HSE write the rules and when they visit they hold you to the standard of their rules but then they say it's only a judge that can give a definitive answer and interpretation of their rules.
Very strange way to work
