Welcome to the consultation hub for our plans for a new development in Chelsea

At The Royal Marsden, we deal with cancer every day, so we understand how valuable life is. And when people entrust their lives to us, they have the right to demand the very best.

That’s why the pursuit of excellence lies at the heart of everything we do. No matter what we achieve, we’re always striving to do more. No matter how much we exceed expectations, we believe we can exceed them still further. We will never stop looking for ways to improve the lives of people affected by cancer. This attitude defines us all and is an inseparable part of the way we work. It’s The Royal Marsden way.

Our home in central London is an iconic building situated right in the heart of Chelsea. We are proud to be a part of the Royal Borough of Kensington and Chelsea – as a world leader in cancer care, as an employer and as a neighbour. That’s why we are currently exploring proposals to sensitively add to the Chelsea site, respecting the rich heritage and history of our buildings, so that we can secure the hospital’s future in the borough for the long-term.

This webpage is where you can learn more about our early proposals to develop our Chelsea site and keep up to date as the plans progress. It will also be where information about public consultation events is hosted in the future.

Our vision is to expand capacity and help more patients access our world-leading care 

To do this we are proposing to improve and extend the Chelsea site to ensure that The Royal Marsden is well-equipped to continue its life-saving treatment, diagnostics, and research.

We want to expand our capacity, modernise our facilities, and provide state-of-the-art technologies within a building which works better for both patients and staff. These innovations won’t just help our patients in Chelsea but will be spread around the world to transform patients’ experience everywhere.

We are proposing to create a new development that will improve every part of a patient’s cancer journey – from diagnosis, through treatment, to living with and beyond cancer.

We also need to grow to meet the increasing demand for our services and still have the space to conduct our practice-changing research. The disease claims around 165,000 lives every year in the UK. We already see around 60,000 patients every year, and conservative estimates show a 2 per cent growth in cancer cases per year nationally.

We cannot afford to slow our pace and have no intention of curbing our ambition. Our research is opening new possibilities in cancer treatment that were unimaginable even a decade ago. We need to expand and modernise so that we can realise these opportunities and improve every part of the cancer experience for patients across the UK and around the world.

Our ambition

While we still have a lot to work through, our ambition is for this development in Chelsea to be a largely donor-funded project, made possible by the generosity of supporters of The Royal Marsden Cancer Charity. The project is dependent on the success of a fundraising appeal by the Charity to cover most of the costs.

The development of our Chelsea site could enable us to:

Improve every part of a patient’s journey – from early diagnosis, through to precision treatment and care, to living with, and beyond, cancer.

Develop innovations in treatment for wider system benefit and help care for more patients going through one of the hardest times of their lives.

Expand and modernise our infrastructure and technology to improve productivity and every part of the cancer experience for patients.

Create a modern, collaborative research environment to revolutionise cancer research to deliver modern, practice-changing new treatments and quicker diagnosis.

Meet the increasing demand for our services and secure our future in Chelsea for the long-term.
