Staff at a Haddenham based company are taking part in a national sleep-out event in London next month.
The 19-strong team from Defaqto, a financial information business based at Haddenham Business Park are joining 1,200 people from more than 100 businesses.
Each member of the company's staff who is participating is aiming to raise £400 each.
So far between them staff have raised £2,700 and in total they are aiming to raise £7,000.
One of the fundraising events was dressing up on a Halloween theme for the day (photo above).
The company's chief financial officer Alastair Brown said: "I came across this sleep-out event in London and decided it was something I wanted to be involved in.
"We are having a lot of fundraising events in our office over the next few weeks - a cake sale, a quiz and a raffle to name just a few."
Mr Brown said although the event was likely to be a lot of fun, there was a serious reason behind it.
He said: "We are not trying to replicate homeless, just raise awareness of it and money for the charity Centrepoint, which aims to give homeless young people a future.
"We are looking forward though to find out who the loudest snorer in our team is!"
The sleep out event takes place at the Greenwich Peninsula on Thursday November 15.
