Tamsin Haigh


Tamsin has a decade of hands-on fundraising and donor management experience in the charity sector, encompassing established global institutions, such as the University of Oxford and The HALO Trust, as well as smaller start-ups, such as a local NGO in Bangkok.

Tamsin worked with the Philanthropy Company from 2017 to 2019, where she supported clients including the British Library, British Council, Oxford Hospitals Charity, St George’s University of London, Sport England, Somerset House, and the Mary Rose Trust. From February 2023, Tamsin is pleased to return as a Consultant.

Most recently, Tamsin has been working with The HALO Trust, the world’s largest humanitarian mine clearance charity – best known for Princess Diana’s famous walk through a minefield in Angola in 1997.

At HALO, Tamsin has taken on various postings at both HQ and country level. Initially, she was posted to Laos, where she was part of the five-person international management team, managing donor reporting, communications and MEAL for institutional funders (FCDO & US DoS) with contracts totalling $8m annually, funding a programme of 700 staff.

She then returned to HQ to act as the Philanthropy Projects Lead, serving as the in-house ‘go to’ for high-value proposal development for projects across the world, taking major proposals from conception through to final submission, often in quick turnaround situations.

Since then, she has been working directly with the local team in Ukraine to support their management of private and governmental funding, secured in response to the significant humanitarian need sparked by the full scale invasion in February 2022.

Skilled in creating fundraising strategy from scratch, and developing systems and processes to help it grow, Tamsin can help with creating a compelling case for support, building and managing a high-value pipeline, and securing major donations from individuals, foundations and corporates through proposals and pitches.
