Set up an online donations page for your chosen cause and include the link in your email signatures. It is a good way to remind internal colleagues why you’re fundraising. Also, you might also get some donations from generous, external contacts!

Dream up an activity coworkers can try to do for 24 straight hours, and stream it live or get the local news to cover it. Dance marathons are great for this. #bustamove. Or you could have our fox mascot costume worn by members of staff for a straight 24 hours, or working week.

It can be hard work to organise fundraising events at the office, so it seems fair that you get some help in return. Ask your HR department if the company operates a matched giving policy. This is when the company would match the amount of money that you fundraise, therefore doubling your total!

Put up an A3 sheet of paper in your office kitchen or staff room and encourage your colleagues to list their skills on there. This could be anything from playing guitar to pottery. Other colleagues can then place bids on receiving a one-hour lesson with that person and their listed skill. This is a great way to share expertise and fundraise at the same time!

Fill a jar with sweets and ask your colleagues to guess how many sweets are in the jar. Charge a small fee to enter and give the jar of sweets to whoever guesses the closest number. You could do this will mealworms if you want to keep it on theme.

Warm up your vocal chords and take the team to a local karaoke night. Charge them a fee on top of the entry money they’d pay or ask for donations for a particular member of staff to sing a requested tune.

Ask everyone to bring along an iPod and hold a silent disco in your meeting room. Dim the lights and get a disco ball involved for extra atmosphere.

If your team are particularly good sports, you could organise sponsored waxing for any willing participants. Book a space where you’ll have lots of room for onlookers and keep passing the donation buckets around. Remember to film the event so that all of the sponsors have video evidence!

Colleagues would need to pay up when they use some of the well-known buzzwords in your corporation.

A classic fun fundraiser that allows teams to pit their strength against each other. Participants pay to play and can win a prize, or in most cases may be happy with the glory of the win, a trophy and a lot of internal and social media coverage of their feat. This can also be done with a friendly neighboring business.

Ask your friends, family, suppliers and local businesses to donate bottles of wine, and a range of non-alcoholic drinks and set up a wine tombola day. Staff or customers pay £1 to draw a ticket to win the bottle with the corresponding number on it.  Simple and for some reason, always popular!

If you have lots of staff, encourage them to bring in the funniest photos of themselves they can find to host a “Funny Photo Contest!” Place all the photos on a bulletin board in a high-trafficked area and put a donation jar underneath each. Individuals can vote for the funniest photo by placing a donation in the corresponding jar.

Generate hype and competition by providing your coworkers with updates like who’s in the lead. At the end, add up the donations and give your winner a prize.
