Street Auction (BBC1, 11am)

IT'S the ultimate task for Mr Flog It!, Paul Martin, who will spend his morning TV moments this week raising cash for a street's neighbour or friend who has helped others using the assistance of experts Danny Sebastian, Irina Aggrey and Tim Weeks.

It’s payback time for the unsung hero, as Martin and his team scour the area for donations to sell at his pop-up auction right in the very street where they live. The idea is to keep it a secret from them as well. Martin knocks on doors of friends and neighbours to tell them about the auction and he is invited in to rummage in garages and garden sheds to look for donations – anything from bikes to 18th Century buttons.

As the end of each auctions, Martin down from his rostrum to surprise the unsuspecting recipient. Today it's Thatcham and

neighbours turn out to surprise 91-year-old Joyce Lovelock, who has been collecting for the British Legion Poppies appeal for 55 years. Joyce became determined to help service personnel after her father’s experiences in the trenches during the First World War. Not only that, but Joyce helps out her "elderly" neighbours by doing their shopping and errands when they can’t manage it.

The aim is to take Joyce and her close-knit family to a VIP day out at the National Memorial Arboretum in Staffordshire. The people of Berkshire, rally round and donate and everyone wants to help – including Joyce – who doesn’t know all the fund-raising is for her.

Tomorrow is Swansea and the emotional tale of Chris James losing his battle with a brain tumour two days before Christmas and leaving behind his partner Sarah and their two young children. Since then Sarah has thrown herself into raising funds for brain tumour research, while caring for her children. This time the mission is to raise enough money to help finish off the family’s garden – a job Chris had started before he became terminally ill.

Wednesday is Beaminster, and forestry worker, Rob Holt, who is well known around Dorset through his work, delivering logs, and helping out in the local community. Last year an ash tree crashed down on him, pinning him to the ground and almost killing him. Emergency services – including his best mate Carl, a retained fireman – had to cut his arm off at the scene. Any money raised is going towards a life-like cosmetic hand which will make Rob look and feel more comfortable.

On Thursday, Calne father-of-two Jim Sutton is featured. He was medically discharged from the RAF after suffering a ruptured artery to his brain, but is now a volunteer helping the young and old, and former military personnel. Jim’s ambition is to visit the grave of his hero, his uncle Fred, a former test-pilot who died while on a manoeuvre in Canada.

Lastly, it's Rogiet, south Wales, and neighbours Ilona Watson and Fay Baxter who started a community café to help bring their village together. Ilona’s husband, has been left severely disabled following a fall and Fay cares for her elderly mother who has advanced dementia. Some much-needed equipment for the community café is on the auction agenda.
