Affinity Instant

Our Affinity Instant account offers you an excellent rate of interest on your savings whilst also financially benefiting an organisation you support – the Affinity Partner*.

Each year, Monmouthshire Building Society will make a donation to the Affinity Partner, equivalent to 1% per annum of the daily balance held in your account. The more you save, the more your organisation will receive.

You can apply to open this account online, by post, or at any of our branch and agency offices.

A list of our current Affinity Partners can be found under helpful links on the right side of the page.
