A further 1 in 6 said they had or would be having a low key Christmas following the death of a loved one.
The research, produced as part of Good Morning Britain's 1 Million Minutes campaign, has highlighted the crisis of loneliness affecting Britain. The show is now urging people to pledge their time to support people who find themselves alone this Christmas.
The award-winning campaign, which is now in its third successful year, has seen more than 100million minutes pledged to help those in need at what can be a depressing time of the year to be alone.
Meryl Davies, Chief Executive of Contact the Elderly, said: “Christmas is seen as a time of joy and celebration but for many people – especially those who have lost a loved one – it can be one of the loneliest times of the year. Nearly half a million older people face spending the festive period alone this year, many of whom have been widowed."
He urged the public to take part in the campaign, making a real difference to the lives of people struggling with being alone in the UK.
