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 Tres Cantos Open Lab Foundation's rating, finances, and Charity Commission status.
Is Tres Cantos Open Lab Foundation a good charity? +

Around 100% 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 Tres Cantos Open Lab Foundation a legitimate charity? +
Yes — Tres Cantos Open Lab Foundation is a legitimate registered charity (charity number 1142577). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/en/charity-search/-/charity-details/1142577. Registration proves status; Clarity Score then summarises filing transparency on paper, not programme impact.
What is Tres Cantos Open Lab Foundation's charity number? +
Tres Cantos Open Lab Foundation's charity number is 1142577. 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.

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 Tres Cantos Open Lab Foundation have reviews and complaints? +

How much of my donation reaches Tres Cantos Open Lab Foundation? +

According to its 2024 regulator filing, combined overheads (fundraising plus governance) were about 3% of total expenditure at Tres Cantos Open Lab Foundation.
