List of mountains of the British Isles by relative height
|This article needs additional citations for verification. (October 2016) (Learn how and when to remove this template message)|
For a longer list, see the lists of Marilyns which include all 2008 hills and mountains in the British Isles with a relative height of at least 150 m.
The relative height is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak on the same landmass. The higher peak is known as a 'parent'. In this table, the prominence parent is used, as opposed to any other definition of 'parent'. The prominence parent of peak A can be found by dividing the island or region in question into territories, by tracing the runoff from the key col of every peak that is more prominent than peak A. The parent is the peak whose territory peak A resides in.
Most of these peaks make it into this list by virtue of the fact that they are the highest point in their local areas. To help readers identify the locations of the peaks, the topographic area of which these peaks are the highest point is listed in the 'Highest point of...' column.

^1 Rois-Bheinn and Beinn Odhar Bheag both have a height of 882 m and are separated by a 524 m drop. They are collectively separated from Gaor Bheinn (their parent) by a 774 m drop making one of them eligible for inclusion in this list. However, without more accurate heights, it is impossible to say which should be included making them an example of a twin peak.
^2 Ben Loyal was at one time shown as having a height of 765m and drop of 610m, from a height on the OS 1:25000 map. The col is a 155m air height. From site visits there is no evidence for any ground 1m higher than the trig pillar, whose flush bracket height is given as 764.1m in the OS legacy database. This was confirmed in 2014 by a survey by Alan Dawson which obtained a summit height of 764.2m, which also caused the hill to be dropped from a list of summits in Britain and Ireland with 2000 ft (609.6m) prominence.
