Where does the money go?

Big C’s four main areas of work focus on supporting local people affected by cancer, funding world-class research at Norwich Research Park, providing vital medical equipment and facilities in the county’s main hospitals and educating people about cancer to improve early diagnosis.

“I play the Big C lottery because the charity was a real help to me when I was visiting the Norfolk and Norwich Hospital for my chemo and radiotherapy. Playing the Big C lottery not only helps the charity continue their brilliant work, but it also gives you a chance to win up to £25,000 for just a small monthly outlay.”

Lottery FAQs

What is the Big C Lottery?

The Big C Lottery is a fun weekly charity lottery draw to raise money to support local people affected by cancer. Entry costs £1 per play and there is a weekly jackpot of £25,000 as well as other cash prizes.

Why does Big C have a lottery?

The Big C Lottery is an alternative way of raising vital funds to support our work. The lottery helps us to engage with new audiences who may not have considered donating to Big C previously. The great thing about the Big C Lottery is that we’re offering our supporters the chance to be a winner every week while raising money to support those affected by cancer.

How does it work?

Big C’s lottery is managed by Unity Lottery (Sterling Management Centre Ltd), a UK company with more than 20 years’ experience of running lotteries for charities.

You can play for as little as £1 per week. For every £1 you play each week you will receive a unique 6-digit lottery number, which will remain yours for as long as you keep playing. You can purchase more than one lottery number if you wish.

Every Friday, Unity generate a random 6-digit winning number sequence (all numbers are between 0 and 9). If your digits are in the same positions as the digits in the winning number sequence, you win a prize!

For example, if the winning number sequence was 6 7 4 3 0 7 and your lottery number is 7 2 4 3 1 7, you will have matched 3 digits in the sequence because three are positioned in the same place.

  • 6-digit match wins £25,000
  • ‍5-digit match wins £1,000
  • ‍4-digit match wins £25
  • ‍3-digit match wins five entries into the next draw
  • For every £1 played on our Weekly Lottery, a minimum of 50p will come straight to Big C. The rest of the income is split between the prize pot (18.4%) and administration costs (31.6%).
What are our chances of winning?

Each £1 entry has a 1 in 63 chance of winning one of four fantastic prizes.

How do I claim my prize if I win?

If you win, your prize cheque will be sent to you automatically, so there is no need for you to make a claim.  You can of course check the latest lottery results anytime by visiting
