We started in 1981, when several UK water companies came together at the Thirsty World Conference. Determined to find a solution to a global crisis that had left billions without water, toilets or hygiene, the idea for WaterAid was born.

As Chief Executive of WaterAid UK, Tim has spearheaded the development of the organisation’s Global Strategy 2022-2032 and it’s four key focus areas: prioritising water, sanitation, and hygiene (WASH) across the health sector; creating sustainable water systems to influence wider global change; strengthening the resilience of water solutions to climate change; and increasing the quality and quantity of funding for WASH.

The links between climate change and the water crisis and water and gender inequality are also key issues Tim is personally passionate about.

In his role, he works with partners and global governments to ensure WASH is represented in rooms where key decisions are made, attending major international events such as COP and the UN General Assembly. He currently leads the Water and Climate Task Force for the Sustainable Markets Initiative, first formed by His Majesty King Charles III, which aims to build a coordinated private sector global effort to achieve a sustainable future.

Tim has spent the majority of his career working in international development. Before joining WaterAid he was Chief Executive of Action on Disability and Development International and held a range of roles with the Equality and Human Rights Commission, Oxfam and Voluntary Services Overseas (VSO).

Our Trustees are recruited through an open application process. Our aim is to always make sure the Board:

  • is diverse and gender-balanced
  • reflects the professional skills and experience we need to operate effectively and sustainably
  • reflects our origins in the UK water industry

We actively encourage people with international development experience and those of African or Asian origin to apply.

Trustees are elected for a four-year term that may be renewed for another four years. Occasionally this is extended further, to make sure specific skills are represented on the Board.

Our Chief Executive is appointed by our Trustees. Along with our Directors, the Chief Executive is responsible for managing our five departments: International Programmes, Policy and Campaigns, Communications and Fundraising, Finance and Information Services, and People and Organisational Development. Our Internal Audit function also reports directly into our Chief Executive.

At WaterAid we are determined to see a world where everyone has access to safe water, sanitation and hygiene by 2030 and we are committed to maximising our impact to help ensure that this is achieved.

We are very aware of our responsibilities to those who benefit from our work as well as our supporters, donors, staff and the public. In setting pay we take seriously our responsibility to ensure value for money in everything we do, always being effective stewards of our resources. This includes using our money wisely to ensure we pay competitive and fair salaries that enable us to recruit and retain staff with the right values, skills and experience to achieve our mission. We aim to remunerate and to review remuneration in a transparent way.

All of our staff have an annual performance review. We believe that basing an element of pay on performance demonstrates our commitment to value for money, accountability to our stakeholders, and reinforces the importance of high standards of performance for all staff.

Pay scales for all staff are set with reference to market conditions, comparing ourselves with similar not-for-profit organisations. Market pay is determined using recognised salary surveys specialising in the Charity and International Development sector. We seek to pay between the median and upper quartile of these comparators.

Pay ranges for the Chief Executive and Directors are set with reference to market data for each individual role, benchmarked using at least three relevant remuneration surveys.

Each year we consider an increase to be awarded on 1 April. Increases are determined taking into account the benchmark data, individual performance and affordability.

The People Committee of the Board provide assurance that WaterAid’s global remuneration policies and principles are being applied. The Committee reviews all proposed increases for Directors and recommends the remuneration of the Chief Executive for approval by the Board of Trustees.

Our Board of Trustees are not remunerated.
