This article provides access to lists of mountains in Britain and Ireland by height and by prominence. (See Lists of mountains below.) Height and prominence are the most important metrics for the classifications of mountains by the UIAA; with isolation a distant third criterion.^[b]^[2] The list is sourced from the Database of British and Irish Hills ("DoBIH")^[c] for peaks that meet the consensus height threshold for a mountain, namely 600 metres (1,969 ft); the list also rules out peaks with a prominence below 30 metres (98 ft) and thus, the list is therefore precisely a list of the 2,756^[d] Simms in the British Isles (as at October 2022).^[3]^[4] Many classifications of mountains in the British Isles consider a prominence between 30–150 metres (98–492 ft) as being a "top", and not a mountain; however, using the 30 metres (98 ft) prominence threshold gives the broadest possible list of mountains. For a ranking of mountains with a higher prominence threshold use:

List of Marilyns in the British Isles, for ranking by height and by prominence, of peaks with prominence over 150 metres (492 ft); or
List of P600 mountains in the British Isles, for ranking by height and by prominence, of peaks with prominence over 600 metres (1,969 ft)

^ "Munros". Scottish Mountaineering Club. 2018. The list of distinct Scottish peaks of 3000ft (914.4m) and over, of "sufficient separation" from their neighbouring peaks. The list that was originally drawn up by Sir H.T. Munro in the Scottish Mountaineering Club Journal in 1891 was unfinished at the time of his death. Munro did not write down a precise definition of what he meant by "sufficient separation", though the character of a mountain did enter into it. Through regular use these hills have become known as the Munros.

^ "The SIMMs". HillBaggingUK. The Simms: A Simm is a hill in England, Wales or Scotland over 600m high with a drop of at least 30 metres all-round. Simm is an acronym for Six-hundred Metre Mountain. The Irish and Isle of Man Simms are also listed on this website. A Subsimm is a hill which just fails (by up to 10m) to qualify on the drop rule, i.e. over 600m with 20–29m drop.
