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 Bletchley Park Trust Limited's rating, finances, and Charity Commission status.

Is Bletchley Park Trust Limited a good charity? +

Bletchley Park Trust Limited scores 85 out of 100 (4 stars — Good) on CharityCompare's Clarity Score, our independent read of its UK regulator filings. Around 82% 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 Bletchley Park Trust Limited a legitimate charity? +

Yes — Bletchley Park Trust Limited is a legitimate registered charity (charity number 1012743). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/en/charity-search/-/charity-details/1012743. Registration proves status; Clarity Score then summarises filing transparency on paper, not programme impact.

What is Bletchley Park Trust Limited's charity number? +

Bletchley Park Trust Limited's charity number is 1012743. 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 Bletchley Park Trust Limited's charity rating? +

Bletchley Park Trust Limited scores 85 out of 100 on CharityCompare (4 stars — Good). 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 Bletchley Park Trust Limited have reviews and complaints? +

CharityCompare does not host public user reviews for Bletchley Park Trust Limited. Instead you get a filing-based Clarity Score, cause spend, reserves and red flags such as late accounts. For formal complaints about a charity, contact the Charity Commission, OSCR, CCNI or the Fundraising Regulator as appropriate.

How much of my donation reaches Bletchley Park Trust Limited? +

According to its 2024 regulator filing, 82% of Bletchley Park Trust Limited's total spending went to charitable activities (3-yr avg across disclosed years).

What are Bletchley Park Trust Limited's overheads? +

According to its 2024 regulator filing, fundraising costs were about 16% of total expenditure and combined overheads (fundraising plus governance) were about 17% of total expenditure at Bletchley Park Trust Limited. The filings CharityCompare uses do not publish CEO or senior-staff pay, so we cannot say what Bletchley Park Trust Limited'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 Bletchley Park Trust Limited receive? +

Bletchley Park Trust Limited reported £7.6m total income in its 2024 accounts, based on UK regulator filings. Five-year trend: growing.

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 Bletchley Park Trust Limited's most recent accounts cover 2024.
