Mermaids

Mermaids scores 0 out of 100 (0 stars — Not rated) on CharityCompare's Clarity Score, our independent read of its UK regulator filings. Around 89% 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.

Yes — Mermaids is a legitimate registered charity (charity number 1160575). Verify it on the official register: https://register-of-charities.charitycommission.gov.uk/en/charity-search/-/charity-details/1160575. Registration proves status; Clarity Score then summarises filing transparency on paper, not programme impact.

Mermaids scores 0 out of 100 on CharityCompare (0 stars — Not rated). 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.

CharityCompare does not host public user reviews for Mermaids. 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.

According to its 2025 regulator filing, 89% of Mermaids'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.

According to its 2025 regulator filing, fundraising costs were about 11% of total expenditure and combined overheads (fundraising plus governance) were about 20% of total expenditure at Mermaids. The filings CharityCompare uses do not publish CEO or senior-staff pay, so we cannot say what Mermaids's chief executive is paid — where disclosure rules apply, senior pay appears in the trustees' annual report on the Charity Commission register.

Mermaids reported £1.3m total income in its 2025 accounts, based on UK regulator filings. Five-year trend: declining.

Filing status: up to date (last filing 2026-06-24). CharityCompare flags late or missing accounts separately from the financial score.
