In the Shared Ownership range, 2-year fixed rates at 90% LTV, both fee and no fee, are down by up to 0.13%.
A 5-year fixed rate with a £999 fee at 90% LTV has also been added.

Aran Mann, product manager at West Brom Building Society, said: “We’re always looking at how we can make our products work harder for brokers and their clients, particularly in today’s environment where affordability pressures remain front of mind.
“These latest changes reflect our ongoing commitment to supporting borrowers, including those with lower deposits, offering them greater value and flexibility across a wider set of needs.
“The support and insight we receive from intermediaries continues to play a vital role in shaping our product range.”
Mann added: “We’ll keep working closely with our broker partners to ensure they have access to competitive and relevant products, backed by the service and clarity they need to guide their clients confidently.”
