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 →](https://www.charitycompare.org.uk/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.

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 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? + Yes — International Water Association is a legitimate registered charity (charity number 1076690). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/en/charity-search/-/charity-details/1076690. Registration proves status; Clarity Score then summarises filing transparency on paper, 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 V1 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 (1 filing concern(s) noted on this profile). 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? + According to its 2024 regulator filing, 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? + According to its 2024 regulator filing, fundraising costs were about 28% of total expenditure and combined overheads (fundraising plus governance) were about 30% of total expenditure at International Water Association. The filings CharityCompare uses do not publish CEO or senior-staff pay, so we cannot say what International Water Association's chief executive is paid — where disclosure rules apply, senior pay appears in the trustees' annual report on the Charity Commission 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 2026-06-24). CharityCompare flags late or missing accounts separately from the financial score. Where is International Water Association based? + International Water Association is listed at London · UK-wide · E14 2BA and operates UK-wide, focused on environment. 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 17 July 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.
