We welcome this full post-mortem report, which will form part of the information provided to the coroner when the full inquest into Zane's death takes place.
We will continue to work with the police with their investigations into the causes of this tragedy and who was responsible.
We await further information provided by other agencies following their investigations, as many questions still remain unanswered into what toxins were present within the property on the night of Zane's death.
Further tests have now been completed by the pathologist who has given a result of carbon monoxide intoxication.
A petrol-driven pump was seized from inside the home address at the time of Zane's death and Surrey Police is conducting further inquiries to establish whether there is any liability or criminal offences in respect of the hire company who provided this equipment.
A seven-year-old boy who died after falling ill during the floods in February suffered carbon monoxide poisoning. Zane Gbangbola and his parents became ill at the family home in Chertsey in Surrey and were taken to hospital, where he later died.
Assistant Chief Fire Officer Simon Moore said Mr Cox was not on a call at the time.
He added: "The circumstances of his death have not been established. We are saddened and upset by this tragic news and our thoughts are with his family and colleagues at this very difficult time."
