Quick review
Wondering whether Monmouthshire Building Society is worth it beyond the bonus? Here is our honest take.
A small Welsh mutual that's been doing the basics well for over 150 years, mostly known these days for a competitive regular saver. Quidsy lists the current Regular Saver as a quick win for anyone who can spare a bit each month. Best for slow-and-steady savers happy banking by app. Heads up: the rate is variable.
Chris' verdictYour personal guide, QuidsyFor the Regular Saver, yes, if you've got money you can drip-feed in each month. The 6.00% rate paired with the £500 monthly cap means you can put away the full £6,000 over the year and end up with about £6,194, which is a tidy bit more than you'd earn in most easy-access accounts at the same time. The £1 minimum and flexible withdrawals make it pretty low-commitment, so there's not much downside to giving it a go.
The main thing to keep in mind is the variable rate. 6.00% isn't locked in for the full 12 months and the society can drop it with 14 days' notice if the market shifts. Worth checking your account every couple of months to see whether the rate still beats what's available elsewhere.
Beyond that, it's a small Welsh mutual doing what mutuals are supposed to do: pay a competitive rate, treat members like members, and stay out of the FCA's bad books. If you like the idea of supporting a community-focused lender that's been around since the year Tolstoy finished War and Peace, it's an easy yes.
