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: £32,783,000 (2025-03-31). 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.

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 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 (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 Guy's and St Thomas' Foundation a legitimate charity? +

The register data used for this profile lists Guy's and St Thomas' Foundation as a registered charity (charity number 1160316). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/charity-details/?regId=1160316&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 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 (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 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 (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 Guy's and St Thomas' Foundation? +

Across the recent disclosed accounts used for this score, 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? +

Across the recent disclosed accounts used for this score, fundraising costs were about 31% of total expenditure and fundraising plus separately reported governance figures amount to about 31% of expenditure (2023–2025, disclosed years); these categories can overlap, so this is not a distinct total of all administration costs at Guy's and St Thomas' Foundation. Guy's and St Thomas' Foundation's annual return for the year ending 31 March 2025 reports 74 employees paid more than £60,000, including 15 employees paid more than £100,000. The highest reported pay band is over £500,000 (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 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.

Are Guy's and St Thomas' Foundation's accounts up to date? +

Filing status: up to date (last filing 2025-12-05). CharityCompare flags late or missing accounts separately from the financial score.

Where is Guy's and St Thomas' Foundation based? +

Guy's and St Thomas' Foundation's registered contact address is in London (SE1 0EH). It tells the regulator it operates in Lambeth, Southwark, with a focus on homelessness.

How much is Guy's and St Thomas' Foundation's chief executive paid? +

The Charity Commission register does not name individual salaries. Guy's and St Thomas' Foundation's annual return for the year ending 31 March 2025 reports 74 employees paid more than £60,000, including 15 employees paid more than £100,000. The highest reported pay band is over £500,000 (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 Guy's and St Thomas' Foundation's money come from? +

Guy's and St Thomas' Foundation reported £34m total income for the year ending 31 March 2025. The largest sources were investments £27m (80%), donations and legacies £6m (18%), other income £928k (3%). Legacies (gifts in wills) contributed £1.3m.

Can I claim Gift Aid on a donation to Guy's and St Thomas' Foundation? +

The register records Guy's and St Thomas' Foundation as registered with HMRC for Gift Aid, so a UK taxpayer can usually add 25p to every £1 they give by making a Gift Aid declaration.

Are Guy's and St Thomas' Foundation's trustees paid? +

Guy's and St Thomas' Foundation's annual return for the year ending 31 March 2025 reports that no trustee received remuneration or other benefits from the charity.

How does CharityCompare score Guy's and St Thomas' Foundation? +

We calculate a Clarity Score of 0–100 from four pillars in Guy's and St Thomas' Foundation'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 Guy's and St Thomas' Foundation'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.
