NHS Organ Donation Register
Becoming an organ donor only takes a few minutes if you register online, but can bring a lifetime of health and happiness to those who are waiting for a transplant. Your family will be asked to support organ donation if, when you die, you are in a position to donate your organs. So make sure you tell them you want to be an organ donor too. Sadly, around three people every day die in need of an organ transplant.
Most organs are donated by deceased donors and used to help someone who needs a transplant. Some organs, like the kidney and liver, can be donated by living donors.
