Common questions about Clean Air Fund's rating, finances, and Charity Commission status.
Is Clean Air Fund a good charity? +
Clean Air Fund scores 84 out of 100 (4 stars — Good) on CharityCompare's Clarity Score, our independent read of its UK regulator filings. Around 99% 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 Clean Air Fund a legitimate charity? +
The register data used for this profile lists Clean Air Fund as a registered charity (charity number 1183697). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/charity-details/?regId=1183697&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 Clean Air Fund's charity number? +
Clean Air Fund's charity number is 1183697. 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 Clean Air Fund's charity rating? +
Clean Air Fund scores 84 out of 100 on CharityCompare (4 stars — Good). 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 Clean Air Fund have reviews and complaints? +
CharityCompare does not host public user reviews for Clean Air Fund. Instead you get a filing-based Clarity Score, cause spend, reserves and red flags such as late accounts (none flagged 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 Clean Air Fund? +
Across the recent disclosed accounts used for this score, 99% of Clean Air Fund'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 Clean Air Fund's overheads? +
Across the recent disclosed accounts used for this score, fundraising costs were about 1% of total expenditure and fundraising plus separately reported governance figures amount to about 1% of expenditure (2023–2025, disclosed years); these categories can overlap, so this is not a distinct total of all administration costs at Clean Air Fund. Clean Air Fund's annual return for the year ending 31 December 2025 reports 35 employees paid more than £60,000, including 10 employees paid more than £100,000. The highest reported pay band is £250,001–£300,000 (1 employee). Individual salaries, including the chief executive's, are disclosed in the trustees' annual report rather than on the register.
