Our review methodology

• Ratings are copied from the business’s public review profiles — we do not write, edit or filter reviews.
• We do not accept payment to change a rating, and paid listings are labelled as such.
• Ratings are re-checked when a listing is updated; the date of the last check is shown above.
• If a rating looks wrong, use our contact form and we will re-check the source.
