With the whole market in view — the demand, the visibility gap, and the perception — the strategic call stops being a judgement and starts being obvious. Principality has two things most brands would kill for: a tailwind, and an unowned position.
The tailwind: the fastest-growing brand in the category
Principality brand interest is up +86% from 2019 to 2025 — the fastest-growing building society over the period. Over the same window, Nationwide is down −25%.
You rarely get to build a strategy on rising brand demand. Principality has it. The job is to point that momentum at something specific.
The opening: the Welsh first-time buyer
First-time home buying is where Principality's perception is strongest — +0.63 sentiment, the highest in the set, and described in customers' own words as "the standout Welsh building society for most first-time buyers." Savings-rate perception sits at +0.53 to +0.85 alongside it.
And crucially, no peer owns this position. The other Welsh mutual, Monmouthshire, is weak in perception (2.39 stars on Trustpilot). The Welsh first-time-buyer story is sitting there, unclaimed.
The move
Own the Welsh first-time-buyer journey end to end — from the first ISA, to the deposit, to the mortgage — ride the +86% brand momentum into it, and close the digital-experience perception gap so the app stops undercutting the service people already love. One position, fully owned, on rising demand. That's where Principality wins.
