International Water Association's annual return for the year ending 31 December 2024 reports that one or more trustees received payments or other benefits. Charity law allows this only in limited circumstances; the trustees' annual report should explain it.

Results and impact evidence

We have not added a source-checked programme outcome for this charity. That is a gap in this profile, not evidence that the charity has no impact. Its annual report may contain results that have not been assessed here.

Reported grants to institutions: £18,843 (2024-12-31). This is spending reported in the annual return, not a measure of beneficiary outcomes or an open grant opportunity. It may already be included in charitable expenditure. Check the source accounts.

What these results can tell you

Counts of services delivered describe activity. They do not by themselves establish lasting change, what would have happened without the programme, or cost-effectiveness. Results with different definitions, populations or years should not be ranked against each other.

Your donation decision

What should you check before donating to International Water Association?

  1. 1. Match the name and charity number

How we score charities +

The Clarity Score is a 100-point rating from UK regulator filings (Charity Commission for England and Wales, OSCR and CCNI). Four pillars — Accountability & Transparency (40), Financial Health (30), Financial Efficiency (20), and Community Support (10) — each scored on a continuous scale, not pass/fail cutoffs. A statutory inquiry sets the score to 0 automatically.

Full methodology →

Accountability & Transparency

Scored from filings

40 points — filing history (15), trustee oversight (15, scaling up to a board of three or more), declared policies (10).

Financial Health

Scored from filings

30 points — reserves (15, full marks 3–24 months, tapering on both sides), income stability (10), liabilities to assets (5, scaling down as debt rises).

Financial Efficiency

Scored from filings

20 points — program expense ratio and fundraising cost, each on a graduated scale (not a single cutoff). Kept at 20% of the total: financial-ratio scoring alone is not a reliable effectiveness signal (see "why not just an overhead ratio?" below).

Community Support

Scored from filings

10 points — volunteer-to-staff ratio from Charity Commission workforce data, scaling continuously up to a 2:1 ratio.

Overall score

Sum of all pillar points. Display stars use the same bands as the labels: 90–100 → 5★ Exceptional; 75–89 → 4★ Good; 60–74 → 3★ Needs improvement; 1–59 → 2★ Poor; 0 → not rated.

Frequently asked questions

Common questions about International Water Association's rating, finances, and Charity Commission status.

Is International Water Association a good charity? +

International Water Association scores 74 out of 100 (3 stars — Needs improvement) on CharityCompare's Clarity Score, our independent read of its UK regulator filings. Around 72% of its spending goes to charitable activities (3-yr avg) and its accounts are up to date. That reflects how transparent and financially healthy it looks on paper — it does not measure the real-world impact of its work, so treat it as one factor alongside the cause you care about. CharityCompare never tells you where to donate.

Is International Water Association a legitimate charity? +

The register data used for this profile lists International Water Association as a registered charity (charity number 1076690). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/charity-details/?regId=1076690&subId=0. Check the current entry and the identity of anyone requesting money. Registration does not verify a particular appeal; Clarity Score summarises filing transparency, not programme impact.

What is International Water Association's charity number? +

International Water Association's charity number is 1076690. Check that number on the official register (Charity Commission, OSCR or CCNI) or this CharityCompare profile before you donate — scammers sometimes reuse real numbers on fake appeals.

What is International Water Association's charity rating? +

International Water Association scores 74 out of 100 on CharityCompare (3 stars — Needs improvement). The Clarity Score (method v1.1) sums four pillars from UK regulator filings: Accountability & Transparency (40 pts), Financial Health (30), Financial Efficiency (20), and Community Support (10). Stars use the same bands as those labels — 90+ is 5★ Exceptional. It is not an impact ranking.

Does International Water Association have reviews and complaints? +

CharityCompare does not host public user reviews for International Water Association. Instead you get a filing-based Clarity Score, cause spend, reserves and red flags such as late accounts (one red flag on this profile: high fundraising costs). For formal complaints about a charity, contact the Charity Commission, OSCR, CCNI or the Fundraising Regulator as appropriate.

How much of my donation reaches International Water Association? +

Across the recent disclosed accounts used for this score, 72% of International Water Association's total spending went to charitable activities (3-yr avg across disclosed years). That is the closest official figure to "how much of your donation reaches the cause" — it is an average across all spending in the filing, not a pound-by-pound breakdown of an individual gift.

What are International Water Association's overheads? +

Across the recent disclosed accounts used for this score, fundraising costs were about 28% of total expenditure and fundraising plus separately reported governance figures amount to about 30% of expenditure (2022–2024, disclosed years); these categories can overlap, so this is not a distinct total of all administration costs at International Water Association. International Water Association's annual return for the year ending 31 December 2024 reports 8 employees paid more than £60,000, including 3 employees paid more than £100,000. The highest reported pay band is £250,001–£300,000 (1 employee). Individual salaries, including the chief executive's, are disclosed in the trustees' annual report rather than on the register.

How much income does International Water Association receive? +

International Water Association reported £8.9m total income in its 2024 accounts, based on UK regulator filings. Five-year trend: growing.

Are International Water Association's accounts up to date? +

Filing status: up to date (last filing 2025-10-28). CharityCompare flags late or missing accounts separately from the financial score.

Where is International Water Association based? +

International Water Association's registered contact address is in London (E14 2BA). It tells the regulator it operates in London, Bangladesh, China, Ghana, Kenya, Netherlands, with a focus on environment.

How much is International Water Association's chief executive paid? +

The Charity Commission register does not name individual salaries. International Water Association's annual return for the year ending 31 December 2024 reports 8 employees paid more than £60,000, including 3 employees paid more than £100,000. The highest reported pay band is £250,001–£300,000 (1 employee). Charities normally disclose the chief executive's pay, or the pay of their highest-paid staff, in the remuneration note of the trustees' annual report and accounts.

Where does International Water Association's money come from? +

International Water Association reported £8.9m total income for the year ending 31 December 2024. The largest sources were trading and fundraising events £4.7m (53%), charitable activities £2.4m (27%), donations and legacies £1.7m (19%).

Can I claim Gift Aid on a donation to International Water Association? +

The register does not record International Water Association as registered with HMRC for Gift Aid. Ask the charity before assuming a donation can be Gift Aided.

Are International Water Association's trustees paid? +

International Water Association's annual return for the year ending 31 December 2024 reports that one or more trustees received payments or other benefits. Charity law allows this only in limited circumstances; the trustees' annual report should explain it.

What was International Water Association previously called? +

The register lists this previous name for International Water Association: The International Water Association.

When was International Water Association registered as a charity? +

International Water Association was entered on the register on 22 July 1999. It is also a company registered at Companies House (company number 03597005).

How does CharityCompare score International Water Association? +

We calculate a Clarity Score of 0–100 from four pillars in International Water Association's regulator filings: Accountability & Transparency (40 points — filing history, trustees, policies), Financial Health (30 — reserves, income trend, debt), Financial Efficiency (20 — cause spend and fundraising cost, on a graduated scale) and Community Support (10 — volunteer-to-staff ratio). An open statutory inquiry scores 0. The score measures reporting on paper, not programme impact. CharityCompare is free for donors, takes no commission on donations, and scores cannot be bought.

How often is this page updated? +

This profile was last updated on 6 September 2026 from the latest UK regulator data available to CharityCompare, and International Water Association's most recent accounts cover 2024. Scores and figures refresh whenever we re-ingest the register, so the page reflects our latest data pull rather than a one-off review.
