Affinity Instant
Our Affinity Instant account allows you to save 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.

Our Affinity Partners

The Dragons boast an array of Welsh Internationals, including; Hallam Amos, Elliot Dee, Cory Hill, Leon Brown, Tyler Morgan and Ollie Griffiths. The region's academy provides a production line of talented youngsters, with many Dragons first teamers progressing from academy ranks to break into the senior lineup. Funds raised through the affinity account will support the academy, which will help produce Dragons stars of the future.

The Wales Air Ambulance Charity provides emergency air cover for those facing life-threatening illnesses or injuries. They have attended over 38,000 incidents in the past 20 years.
