Introduction to the list
The concept of the BritFours ('Brit4s') was first explored by Myrddyn Phillips and Aled Williams in March 2018 in an article published on Mapping Mountains (see here) and the Relative Hills Society annual Journal Relative Matters. The list is now available in its entirety on the HaroldStreet website (see here), with a Hall of Fame for those peak-bagging it now published here by Europeaklist for the first time.
The Brit4s comprise all known hills in Scotland, Wales, England and the Isle of Man of 400m and above, and below 500m in height, with 30m minimum drop. The number of Brit4s changes over time, as surveys are carried out and LIDAR data analysed. In August 2025 the number stood at 2051 peaks.
The data were originated by the late E D ‘Clem’ Clements, Myrddyn Phillips and Aled Williams, with contributions by a number of people including the Database of British Hills (DoBIH).
The Brit4s is the next natural height boundary downward from the Simms and Dodds and the data combine the Scottish 400m Tumps, The Fours – the 400m Hills of England, Isle of Man 400m Tumps and Y Pedwarau – the 400m Hills of Wales.
The list is co-authored by Myrddyn Phillips and Aled Williams with relevant changes including reclassifications, summit relocations and name changes being fed into the list published on Haroldstreet.

The Brit4s Hall of Fame ('Brit4HoF')
Alex Cameron, the Brit4s HoFMeister, had been keeping a Register of Progress of those working through the Brit4s for some years previous to 2024, publishing the updated Register on some social media platforms to a limited audience.
The first Hall of Fame ('HoF') of peak-baggers working through this list is now published in the public domain on this website. A new Table will be published here each spring relating to the previous year - for example, the Table for the year to 31st December 2025 will be published in the spring of 2026.
The new Hall of Fame takes a somewhat different format from the annual Tables published online and in the journal of the Relative Hills Society. There is one Hall of Fame, but without the features of an Upper Hall or Levels used elsewhere. Instead, those achieving higher thresholds receive Bronze, Silver or Gold Awards. The threshold for entering the Hall of Fame is 400 peaks. The thresholds for the Awards are:
Bronze: 800 peaks
Silver: 1200 peaks
Gold: 1600 peaks.
Another new feature in the Table are columns showing completion percentages for the hills on the whole list, and those in Scotland, Wales, England and the Isle of Man.
Nobody has yet completed the Brit4s. It is a big hill-list, and a number of peaks on the list may, as with the Dodds (500m hills of Britain and Isle of Man), present ascent problems even to those with advanced rock-climbing skills. The Trotternish hills, on the Isle of Skye in Scotland, have a number of especially challenging ascents.
Recuitment
Fourteen made their appearance in the first Hall of Fame (2024). The HoFMeister is keen to expand the 2025 ff. Tables to more people, as it is clear that there are many who have done 400 Brit4s or over who would be eligible to join.

Note: for 2025 and following years, the Brit4s will be a hill-list adopted by the Relative Hills Society (RHSoc) and published, in a simpler edited format, in their annual journal Relative Matters and on their website.
