Professional, helpful staff who are more than willing to help with problems. We're 2 old folk who needed, and received all the help we needed. Well done to Morgan in the Risca branch. We're extremely grateful.

App don't work for app only accounts!

Offers app only accounts, and the app don't work!
5 months ago, I opened an app only savings account. Then I got a new phone. Tried to set up the app on the new phone, and it is impossible.
First I selected I have an account and am registered for the app. They send me a SMS with a code to continue the registration which the app accepted the code...only to immediately say the number is not recognised! What??? You just accepted the code!
OK I thought, I will register to use the app as a new user, entered all my details, only for it to say I am already registered!!! Basically I have no way of accessing my account now unless I run 2 phones which I do not want!!!

Think twice before you take out a mortgage with MBS

The Bank of England has reduced the base rate six times in the last eighteen months by a total of 1.5%. The Monmouthshire: three times by a paltry 0.5%. They will say they are not obliged to follow the BoE rate and have a responsibility to borrowers and savers... But with a 61% rise in profits this year, MBS's claim to be run for the benefit of their members sounds very, very hollow.

Thank you for taking the time to leave us a review, we understand that interest rates are a key concern for customers.

When reviewing our interest rates we consider market conditions, regulatory requirements, the need to maintain financial stability and long-term sustainability for all customers. We regularly review our rates to ensure they remain competitive and aligned with our values.

As a mutual organisation, we do not have shareholders to satisfy, which means our focus is on balancing fair returns for savers with affordable lending for borrowers.

Profit made helps to keep the Society secure, invest in our future and provide protection for our customers and the Society. We’re working hard to improve our systems which will enhance our customer experience and help us to become more efficient so that we can offer more competitive products across savings and mortgages in the future.

Excellent service in branch. Each visited greeted by knowledgeable friendly staff who couldn't do more to help. Feels like money in safe place compared with App based digital accounts

The extra 1-2% they offer is not worth the hassle

Signed up for the regular saver account since they had slightly better rates than other banks. Now it is coming up to christmas and I need to access the money i saved but unfortunately, like many others, i am unable to access the app. Despite multiple uninstall/reinstall attempts. Called them up and apparently they have an internal issue which they are trying to resolve but they can't give a time frame on that and no guarantee that we will be able to access our accounts before Christmas. This is disgraceful. Avoid!

Earlier this week I got my Coventry BS account working through their phone app, so I thought I'd try the Monmouth app too.
12 Dec Installation doesn't even fully complete so it's not a problem with verification. Takes ages "Getting things ready" then after "Before using the app agree terms and..." & ticking agree boxes and Continue it just freezes.
13 Dec several remove, reinstall, reboot and restarts later, it finally installed and asked for my mobile number, sent passcode. Currently frozen at accepting that. Time to reboot and reinstall. Again.
Still 13 Dec. Reinstalled, rebooted, powered off and on, now freezing same as yesterday, doesn't get as far as asking for my mobile number.
So MonBS, maybe you need to find another app developer, get customer testing/validation before you offer the app again ?

Failed yet again to open an account with MBS.

Tried 3 times to open a regular savers account. The app was unable to verify any of my 3 bank accounts. Gave up in September to open an account. I was hoping by November the MBS app would at least be on a par with late 90's tech rather than stone-age but seemingly not. How MBS have any online customers is astonishing. Judging by the appalling reviews, customers who have managed to open online accounts by and large wish they hadn't.
I have online accounts with Cumberland, Leeds, Coventry, Principality, West Brom, Nationwide building societies and have had no difficulty in opening accounts with them or had any issues with accessing my accounts. MBS should have a look at their systems and maybe learn something from them.

I paid off my mortgage with…

I paid off my mortgage with Monmouthshire Building Society, but they still took another full payment afterwards. I could see it showing under my pending transactions and tried calling several times, you simply can’t get through on any of the numbers. When someone eventually called me back, they assured me the extra payment wouldn’t be taken. And guess what, it was.

Now I’m left chasing them again, and getting through is a nightmare. After years of being a customer, I expected much better communication and care, especially at such an important point like mortgage redemption. Really disappointing experience.

App is not fit for purpose

App is not fit for purpose.
Opened a regular savings account due to the decent percentage, however I’m thinking of closing this to go with another bank because of how glitchy and awful the app is to use. I’m still yet to see my deposit in my account which has been 2 days since I sent this over. The app constantly crashes, it’s something out of the Stone Age. Really awful. Wish I hadnt bothered.

As a Building Society, our electronic payments are initially received into our bank account before being uploaded to our customers’ accounts, this means that electronic payments may take a little longer to show on your account.

Opened a regular saver account and easy access account on the app. Eventually managed but not without a lot of hassle. The app is the worst I have come across and is not fit for purpose. It should be discontinued immediately until it can be replaced with something better (it can't be worse!!!).

Tried to register for online banking. Entered everything asked for correctly. Then I got a tick - good I though, all sorted. But no because under the tick was 'Registration Failed'.

This Building Society is archaic, very poorly run and managed with IT from the dark ages. Why not look at apps that work and use them. Why not have an IT system that is at least newer than 50 years old. And sort out your systems and procedures so they are not so archaic. I can give you a list of Building Societies to look at as excellent examples

Appalling customer service

Had conversation with a staff member after problems opening a savings account.
They asked for proof of address to be sent, did not explain why except to say there was a problem with non delivery of a letter.
Did not understand but complied anyway as they had a good deal.
Nothing happens.
Sent a request for contact via their online form but again no reply.
Looks like I dodged a bullet!

APP Application ONLY

My wife and i have been using the regular saving accounts with the Monmouthshire Building Society for an number of year paying in the maximum each month
Yesterday we received notice that one of our Regular Saving Accounts is maturing shortly so we tried to open a new Regular Savings Account only to find that now this can only be achieve by a APP. On contacting Monmouthshire Building Society i was told the only way to now save with them is through the APP or Branch. As we are miles away from any Branch that is not possible.
Thankfully i decided to look at the reviews on Trustpilot and i am pleased i did as the reviews are TERRIBLE.
So now we off to one of Monmouthshire Building Society's Competitors to save.

application submission issues but good overall

Like many others, I was irritated by the online sign-up process for their Regular Saver Edition 8. I had installed their app beforehand from the Google Play Store. The issues occurred at the end: verification of my bank account and the final part where I was told not to close or refresh the page. I attempted again and had a similar outcome. Eventually, after a few days, I received my welcome email with the details required for registration and easily got the app to work. It has worked since installation and has never crashed.Paying in is much like any other building society—you employ their account through a bank, using the account number as the reference to identify the payment. You initiate payment from your bank. It's all dead easy. The payment takes 24 hours and updates after 9 AM, as do others (not Nationwide, as they use their own accounts).Reading the comments, I hear the frustration, but you just need to be patient. In comparison with others like Coventry, Yorkshire, etc., well, they would be faster and less prone to bottlenecks with their low interest rates, I wouldn't expect a rush to sign up, so I've cut Monmouthshire some slack! With these rates and without penalty withdrawals it was predictable there would be a higher than usual uptake. There were bound to be a few teething troubles at first.

Very Poor and limited functionality app

Very poorly designed app and only offers limited functionality, and faster payment is not fast either, every transaction takes a day which is less than ideal. App crushes multiple times. both transfer in/out takes a day (maybe more). Apart from the recent good offer of 6% interest in exclusive reg saver, nothing about this Monmouthshire BS is good. Only dived into becoming their customers because of these saving offers but all this negatives are now making me regret my decision

Absolutely terrible building society

Absolutely terrible building society. I don't understand how financial companies like this are able to stay in business. Have been trying to open a Regular Saver Account for 6 weeks and still no progress They take days/weeks to answer anything and lose documents you send to them. I think they are stuck in the past and simply cannot cope with online banking. Have given up and cancelled application.
