In 1937, Alfred and Margaret Bent started to sell roses in the front garden of their terraced house on Warrington Road in Glazebury.
The summer weekend’s entertainment centres on Bents’ indoor beach with the addition of a temporary grass area where visitors can take part in giant garden games while enjoying a summer barbecue.
There will also be a celebratory photo booth which will provide the chance to win £80 of Bents’ vouchers. Visitors are invited to post their photos on social media with the hashtag #Bents80th.
There will be face painting, a treasure hunt, balloons, DJ, a caricaturist and a children’s entertainer and the centre is selling 80th anniversary gifts such as cushions, mugs, gloves, fudge and marmalade.
Managing director Matthew Bent, a third generation family member, says he wants "as many people as possible, customers young and old, new visitors and those who have been with us along the way, to join in for a fantastic celebration of Bents 80th year".
He adds that the celebration gives the chance to invite customers, suppliers and supporters in general to the centre and to thank them for their help over the years.
Bents says a lot of what customers look for now is "trust and experience" and the event will showcase Bents' pedigree as a family-owned company with family values.
