Bonhams is waiving all charges which means 100% of proceeds are going to the NHS Charities Covid-19 Urgent Appeal. Funds from the NHS Covid-19 appeal will help support the health and wellbeing of NHS staff and volunteers supporting Covid-19 patients in ways above and beyond which NHS funding can ordinarily provide. The appeal has a target of £100 million.

Ellie Orton, Chief Executive of NHS Charities Together, said: "As the nation adjusts to life in lockdown, the commitment of NHS staff and volunteers shouldn't be far from our minds. These are the people who leave their homes to care for others and work tirelessly in the face of the virus when they're needed most. It's easy to feel powerless in these challenging times but this campaign is a way we can make a difference, to look after these heroes so they can give the best care possible in these unprecedented circumstances."

Patrick Masson, Bonhams Managing Director for the UK and Europe said: "The NHS staff and volunteers are heroes to us all. We at Bonhams are honoured to host this initiative and to donate the skills we have at our auction house to support those who are working so hard for us on the frontline."

Money raised in the auction will go towards:

1. Funding well-being packs/gifts for staff and volunteers on wards/departments (this could include food deliveries, high energy/protein bars/drinks, snacks, refreshments, wash kits, overnight stay kits.)
2. Cost of travel, parking, accommodation for NHS staff and volunteer's expenses
3. Other items as requested by NHS Charities that enhance the well-being of NHS staff and volunteers caring for Covid-19 patients.
