Every Christmas since 2014, Robert and Amanda Dempsey create an elaborate Christmas lights display outside their home.
The house, in Turves, Cambridgeshire, attracts thousands of visitors every year. These visitors donate money to Cancer Research - the Dempseys' nominated charity. Mr Dempsey lost both his parents to cancer.
"We do it in memory of my parents. A lot of visitors have come here, they've all lost family to it."
The couple have raised over £50,000 for the cancer research and awareness charity.
It takes the Dempseys about a month to assemble the display, and the pair bought two diesel generator to power the lights.
"My wife says I've got a bit of OCD - obsessive Christmas disorder. It started off small and it just grew and it got a mind of it's own. Now it's taken over our Christmas every year."
Mr Dempsey hopes to bring take his fundraising total from £50,000 to £100,000 within five years.
