Tarnside is a consultancy that helps charities and not-for-profit organisations deliver life-changing improvements through fundraising. We work with causes we respect, and with whom we can empathise. We endeavour to work with integrity and humour, and use our collegiate approach and skilled office team to maximise value to our clients.

We have an unparalleled reputation for supporting charities in their work, and for delivering major fundraising campaigns. Working alongside our clients we use our expertise to build in-house skills, strengthen charities’ work and enable our clients to achieve their goals.

In the last five years we have helped raise tens of millions, leading successful appeals between £4M and £36M for clients including Chetham’s School of Music and Cheshire Community Foundation. ‘Behind the scenes’ we work with leading charities in the UK and abroad on their future strategies and fundraising capacity.

Our case studies provide valuable insights into the efficacy of our work, and demonstrate a return on investment of between £23 for and £76 for every £1 spent. Our materials have been selected for use by the Open University in their ‘Winning Resources and Support’ module: an internationally respected course for Fundraising professionals.
