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 Thrombosis UK a good charity? + Thrombosis UK scores 90 out of 100 (5 stars — Exceptional) on CharityCompare's Clarity Score, our independent read of its UK regulator filings. Around 98% 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 Thrombosis UK a legitimate charity? + Yes — Thrombosis UK is a legitimate registered charity (charity number 1090540). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/en/charity-search/-/charity-details/1090540. Registration proves status; Clarity Score then summarises filing transparency on paper, not programme impact. What is Thrombosis UK's charity number? + Thrombosis UK's charity number is 1090540. 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 Thrombosis UK's charity rating? + Thrombosis UK scores 90 out of 100 on CharityCompare (5 stars — Exceptional). 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 Thrombosis UK have reviews and complaints? + CharityCompare does not host public user reviews for Thrombosis UK. 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 Thrombosis UK? + According to its 2025 regulator filing, 98% of Thrombosis UK's total spending went to charitable activities. 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 Thrombosis UK's overheads? + According to its 2025 regulator filing, fundraising costs were about 2% of total expenditure and combined overheads (fundraising plus governance) were about 2% of total expenditure at Thrombosis UK. The filings CharityCompare uses do not publish CEO or senior-staff pay, so we cannot say what Thrombosis UK'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 Thrombosis UK receive? + Thrombosis UK reported £293k total income in its 2025 accounts, based on UK regulator filings. Five-year trend: growing. Are Thrombosis UK'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 Thrombosis UK based? + Thrombosis UK is listed at United Kingdom and operates UK-wide, focused on health. How does CharityCompare score Thrombosis UK? + We calculate a Clarity Score of 0–100 from four pillars in Thrombosis UK'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 Thrombosis UK's most recent accounts cover 2025. Scores and figures refresh whenever we re-ingest the register, so the page reflects our latest data pull rather than a one-off review.
