Sandbags can keep water out for short periods which can be improved by using them in conjunction with plastic sheeting.
However sandbags do seep water even when well-stacked and trodden into place.
As a result, the Government strongly encourages people to use purpose made flood protection products, such as flood boards, non-return valves for plumbing and air brick covers.
There is more information on sandbags available on the government's website.
Individual property owners are responsible for protecting their own property and land from flooding. Some local authorities may issue sandbags, but if they do provide them, there will be limited numbers and those most vulnerable or at risk will get them first so it’s best not to rely on them providing them for you.
