Monmouthshire Building Society completed £219m in gross mortgage lending for the year to April 2025, down from £238m the year before.
The mutual’s mortgage assets rose to £1.38bn, compared to £1.36bn previously, while its net interest margin was flat at 1.9%.
It said competition “remained fierce” over the year, but effective pricing and competitive products allowed the mutual to manage its growth sustainably.
The mutual said its loan loss provisions decreased, and arrears stayed low as a result of its responsible lending policy and underwriting criteria.
Some 94 accounts were in arrears of one month or more, slightly down from 97 at the end of the previous year. This was at a value of £300,000.
Monmouthshire Building Society delivered a profit after tax of £3.7m, up from £2.3m the year before.
