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.
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 Guy's and St Thomas' Foundation's rating, finances, and Charity Commission status.
Is Guy's and St Thomas' Foundation a good charity? +
Guy's and St Thomas' Foundation scores 70 out of 100 (3 stars — Needs improvement) on CharityCompare's Clarity Score, our independent read of its UK regulator filings. Around 69% 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 Guy's and St Thomas' Foundation a legitimate charity? +
Yes — Guy's and St Thomas' Foundation is a legitimate registered charity (charity number 1160316). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/en/charity-search/-/charity-details/1160316. Registration proves status; Clarity Score then summarises filing transparency on paper, not programme impact.
What is Guy's and St Thomas' Foundation's charity number? +
Guy's and St Thomas' Foundation's charity number is 1160316. 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 Guy's and St Thomas' Foundation's charity rating? +
Guy's and St Thomas' Foundation scores 70 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 Guy's and St Thomas' Foundation have reviews and complaints? +
CharityCompare does not host public user reviews for Guy's and St Thomas' Foundation. 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 Guy's and St Thomas' Foundation? +
According to its 2025 regulator filing, 69% of Guy's and St Thomas' Foundation'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 Guy's and St Thomas' Foundation's overheads? +
According to its 2025 regulator filing, fundraising costs were about 31% of total expenditure and combined overheads (fundraising plus governance) were about 31% of total expenditure at Guy's and St Thomas' Foundation. The filings CharityCompare uses do not publish CEO or senior-staff pay, so we cannot say what Guy's and St Thomas' Foundation'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 Guy's and St Thomas' Foundation receive? +
Guy's and St Thomas' Foundation reported £34m total income in its 2025 accounts, based on UK regulator filings. Five-year trend: stable.
