The 3.49% 5-year fixed is available on purchases only, through intermediaries and direct from the lender.
The 95% mortgage is available on loans from £95,000 to £300,000 across England and Wales, excluding London and the South East.
The rate is fixed at 3.49% until 31 October 2026, when borrowers will revert to Vernon’s standard variable rate (SVR) of 5.2%.
Early repayment charges (ERCs) apply for the first five years.
Brendan Crowshaw, head of mortgage and savings distribution at Vernon Building Society, said: “We’re currently seeing strong demand for high LTV loans from first-time buyers and this low-rate mortgage comes with no arrangement fee to help minimise the buyer’s upfront costs.
“Plus, our common-sense approach to underwriting means we’ll consider every client’s circumstances on an individual basis.”
