London Deputy Mayor takes to the road to urge Londoners to give blood and keep the capital’s hospitals going during difficult winter months

28 November 2025

London's Deputy Mayor for Communities and Social Justice is backing an urgent appeal for Londoners to give blood during the difficult winter months when vital stocks come under strain.

The buses are emblazoned with a powerful message that London’s hospitals need one donation of blood every 90 seconds to meet the need of patients.

The buses are designed to inspire blood donation and raise awareness of the critical need for blood donors during the challenging winter months. The double-deckers will travel on routes near 3 major blood donor centres, in Brixton, Bow and Shepherd’s Bush into December.

Dr Weekes-Bernard will be joined on the bus by influencer and sickle cell campaigner Simply Sayo, and London blood donors and recipients, whose lives have been saved or improved by the generosity of the capital’s blood donors.

The final stop for the bus will be the Brixton blood donor centre, where Dr Weekes-Bernard will meet blood donors and centre staff before making her own blood donation.

Over the next 6 weeks there are more than 23,000 unfilled blood donation appointments in London, with the capital accounting for just under half (42%) of all unfilled slots across England.

Any shortfall in donations will hit London particularly hard, as its hospitals use the lion’s share of blood collected across England.

NHS Blood and Transplant data shows that one in every 4 blood donations used by the NHS in England last year went to hospitals in London. That’s 921 lifesaving units every day, or one every 90 seconds.

NHSBT particularly needs donors with the Ro blood subtype, which is used to treat patients with sickle cell, an inherited blood disorder that disproportionately affects people of Black African and Black Caribbean heritage.

Across London there are more than 3,000 Ro donors who are eligible to donate but who haven’t made an appointment in the past year. NHSBT and City Hall is urging those donors to do something amazing this winter and make an appointment to give blood.

Social media influencer Simply Sayo, who has more than 400,000 Instagram followers, has partnered with NHSBT to launch a year-long campaign to recruit 16,000 additional Black heritage blood donors to help people living with sickle cell.

Sayo, real name Adesayo Talabi, lost 2 of her sisters to sickle cell and is focussed on using her platform to mobilise Black communities to become blood donors, as Black heritage donors are 10 times more likely to have the Ro subtype than the White population.
