How we rank
Each business is scored on its average rating weighted by how many ratings it has, so a handful of perfect scores cannot outrank hundreds of near-perfect ones. Reviews left on LocallyIrish.ie and the business's Google rating are counted together; the rating shown on each entry is labelled with its source. A Google rating needs at least 5 ratings to count. Businesses without enough ratings are listed separately, unranked. Paid listings cannot buy a higher position. The list refreshes hourly.
