We are perched on a faded, pink velveteen sofa in a rickety caravan, Martha Carney is talking on the radio and Valerie is making us a cup of tea. She is one of the hundreds of people left homeless after last summer’s severe downpours in England. Valerie was told that she would be living in this cramped space for 10 weeks; she’s been here for 10 months, along with three other family members and a dog.

Look Left Look Right’s new verbatim show offers a glimpse into the lives of a dozen or so deluged householders from flood-hit towns who are still facing headaches over repairs and insurance estimates.

They pass around the biscuits, show us photographs of their waterlogged villages and tell us their stories. Zog had bought his dream house but now he “couldn’t give it away to a family of mermaids”. Gavin remembers the wallpaper peeling off the walls in his home, and the sweaty-sock smell left by the muddy water.

Every time a performer pops into the caravan, they turn the page on a calendar that gives us the name and occupation of the person we’re listening to. Clocking in at a mere 30 minutes, this bit of documentary theatre may not be as powerful as other Fringe shows – such as the campaigning Deep Cut and the admirably complex Motherland – but it is earnest, engaging and often a ticklish pleasure.

These tales of people let down by councils, insurance companies and unscrupulous developers are fringed with hope as well as exasperation. Sue and Jonathan from Whitney have become experts on the Gulf stream; two women natter gleefully about how some things have changed for the better in their village since the flood. The show also has a feeling for how familiarity breeds warmth – most touchingly, in the relationship between a couple who turn to each other and smilingly say: “It’s amazing we’re still together isn’t it?”
