The best advice at this stage is for people affected to contact their insurer, who will be able to provide advice and support on emergency payments and the repair process.
If you encounter any issues when contacting your insurer please do not hesitate to call Andrews office, he has a dedicated team of caseworkers who will assist you where possible.
