Jersey Fire & Rescue believes the explosion at Mont Pinel in June occurred due to the 'ignition of a mixture of a flammable gas and air' that accumulated within a property.

The investigation into the disastrous event is still ongoing.

Details about what the igniter and gas were have not been released, but we're told experts are still working on 'determining why the incident took place'.

Island Energy has acknowledged the investigation and has decided to take another look at its network.

The company had previously said, after their investigation, that there was 'no gas escape'.

A spokesperson says:

"As part of our broader safety programme in Jersey, we are conducting an additional survey of the network.

"Households and business customers will soon receive a letter informing them of a visit, explaining why we are conducting the surveys, and the procedure”

The blast occurred late on 26 June, with neighbours reporting hearing a large 'bang'. 

A wall partially collapsed at Elizabeth Villas at Mont Pinel and a family of four had to be rescued by emergency services. 

The parents were found 'under rubble' and had to have hospital treatment, while their two young children, aged two and five, were unharmed. 

Most evacuated families have now been able to return home.

An expert from the UK was brought in to help with the investigation.
