UK Blood Donation Rules for Donors

The rules for giving blood are strict - but necessary. In some cases, it can be harmful for the donor as well as the person receiving it.

Information in this section highlights current blood donation rules and restrictions that apply for donor eligibility in the United Kingdom.

Blood Donor Guidelines and Restrictions

As a rule, most people between the ages of 17 and 66 can give blood without donor restrictions.

UK blood donation rules say you need a good level of general health and wellbeing and weigh between 50 kg and 160 kg (7st 12lb - 25 stone).

Some blood donor restrictions apply to anyone over 70 years old. Thus, some seniors would need to have given blood in the last two years if they want to continue donating.

The National Health Service has several recommendations. They say women should wait a period of 16 weeks (4 months) and men 12 weeks (3 months) between each offering.

Other restrictions apply to women who are under 20 years old, weigh less than 65 kg, or under 168cm tall. These females may need to have their blood volume estimated before they can give a blood donation.

The vast majority of the public in the United Kingdom are potentially able to give blood. But, some do get ruled out from donating. The principle reasons why you cannot give blood fall into two main categories:

  1. You may get asked not to donate to protect your safety. This applies if evidence suggests that donating blood might harm you.
  2. You may get asked not to donate your blood if evidence suggests that your donation might harm the patient receiving. This includes situations where a specific behaviour may have put you at a higher risk of an infection. That means it could get transmitted to a patient through blood transfusion.

The UK rules about giving blood are a requirement of European law. There are several expert committees who periodically review the evidence relating to blood donation exclusions and deferrals.

Their advice relates most to the overriding safety of blood donors and patients.

This ensures the policies applied by the UK Blood Services get based on the best available scientific evidence.

Changes to Blood Donation Rules

The government announced a change to some of the blood donor restrictions for men who have sex with men.

Starting in the summer of 2021, men who are in a long-term relationship will be able to donate blood in England without having to wait three months.

Religious Beliefs

You can contact the UK's National Health Service Blood and Transplant for more information about religious perspectives. But, as a rule all the major religions in the United Kingdom support the principles of blood and organ donation.

They also agree that no one should ever get pressured into making a donation. It should always be a matter of personal choice.


How Do You Become a Blood Donor?

As a rule, you can donate blood if you are between 17 and 66 years old, weigh over 50 kg (7st 12lb) and you are generally in good health.

Those who are over 70 should have given blood in the previous two years if you want to continue donating blood.

Can You Donate Blood if You Have Diabetes?

In fact, diabetics may donate blood providing they meet all other medical requirements. Note that if you used bovine-derived insulin (from cows) before, this results in a deferral from blood donation.

The syringe used by insulin dependent diabetics should get used by them, and no-one else, if the syringe is then reused.

Can You Give Blood if You Have a Tattoo UK?

Individuals with body tattoos must wait four (4) months after having a tattoo or piercing before they can give blood. Tattoos and UK blood donation rules are similar for those who have received permanent or semi-permanent make-up.

Note: You can donate blood following acupuncture providing a qualified NHS or Health Care Professional did it.
