Cancer Research UK

What it is

Cancer Research UK (charity number 1089464, registered 2001) is, by its own and widely accepted description, the world’s leading cancer charity. It states plainly: “We exist to beat cancer.”² The work is research funding across more than 200 cancer types, supported by health information services, a patient community, and a fundraising machine that includes Race for Life and Stand Up to Cancer.²

It is governed by 14 trustees and employs 5,169 staff, supported by around 26,000 volunteers.¹ The charity reports that its work has helped double cancer survival in the UK over the past 50 years.²

Where the money actually goes

In the year to 31 March 2025, Cancer Research UK reported income of £734.8m and total spending of £714.7m.¹ That is a surplus of roughly £20.1m, or about 97p spent for every £1 raised in the year. A charity running a modest surplus on a base this large is doing the unglamorous part of the job correctly.

On its own figures, CRUK spent £403m on new and ongoing research in 2024/25, about £4m more than the year before, and says it remains on track to exceed a £1.5bn research-investment commitment across the five years from 2021/22 to 2025/26.³ It also publishes the donor-facing efficiency figure: for every £1 donated in 2024/25, 78p was available to beat cancer.³ That implies roughly 22p going to fundraising and other costs, which is in the normal range for a charity that runs large public fundraising events, and CRUK deserves credit for stating it openly.

How effective is it

Research funding is a long-horizon bet. You do not get a cost-per-life-saved number the way you do for a bednet programme, because the payoff arrives years later and is shared across the whole field. So the case for CRUK is not “cheapest lives saved this quarter.” It is scale, focus and track record: the largest charitable cancer-research funder in the world, a credible claim on contributing to doubled UK survival rates, and a published efficiency figure you can actually check.²³

The honest caveat is about cause area, not competence. If your goal is the most measurable good per pound right now, the strongest global-health interventions have cleaner cost-effectiveness evidence than any research charity can offer. That is a feature of funding science, not a knock on how CRUK runs itself.

The bottom line

Give with confidence. Cancer Research UK is focused, financially healthy, ran a surplus in its latest filed year, and is unusually upfront about how much of your money reaches the science. If you want to fund UK cancer research, this is the obvious and well-run choice. If your priority is the tightest measured cost-per-outcome rather than research, look at the global-health alternatives above, but that is a difference of strategy, not a fault in CRUK.
