The sparkle of Christmas tinsel will be lighting a house to raise cash for leukaemia.
Dave Press has been putting up extravagant decorations outside his home in Battlers Green Drive, Radlett, for the last ten years.
In the last decade, the 69-year-old has raised £15,000 for Leukaemia and Lymphoma Research.
He said: “It is great fun. In the first year I started I raised £1,000 and did not realise I could make that much. I thought I would carry on doing it and the tradition just stuck.”
The father-of-three was inspired to decorate his house after his neighbour, Edith Oakley, lost her son to leukaemia in 1959.
Mr Press has been enlisting the help of his seven grandchildren to get the house ready in time for the big switch on.
He will also be dressing up as Santa Claus handing out sweets to the children, and the day will be ending with a free fireworks display.
All are welcome to come and see Mr Press turn on his Christmas lights at 5pm on Saturday, December 1.
