This is a list of Hewitt mountains in England, Wales and Ireland by height. Hewitts are defined as "Hills in England, Wales and Ireland over two thousand" feet 2,000 feet (609.6 m) in height, the general requirement to be called a "mountain" in the British Isles, and with a prominence above 30 metres (98.4 ft); a mix of imperial and metric thresholds. On 5 December 2018, the BBC announced that Foel Penolau had been re-surveyed and promoted to Hewitt status (and by definition, to Simm status). As has Foel Cedig.
