This was coupled with a 40.6% decrease in new mortgage customers – from 4,076 last year to 2,420 in the period ending 30 June 2026.
Its total mortgage assets saw a decrease of £200m from £4.4bn to £4.2bn.
Describing the mutual’s growth as “resilient”, Sue Hayes (pictured), CEO of Nottingham Building Society, said: “After two consecutive years of double-digit growth, 2025 represented a year of deliberate consolidation, and that disciplined approach continues to shape our strategy in 2026.
“Against a complex backdrop of inflationary pressure, geopolitical instability and continued competition across mortgage and savings markets, we have stayed focused on delivering for members while progressing the society’s long-term transformation.
“During the first half of the year, we continued to embed our strategy as a modern, specialist residential lender, investing in our core banking and technology foundations, strengthening our intermediary proposition and taking a disciplined approach to lending growth.
