CMC Invest Avis 

Was amazed at the speed of my ISA transfer to thanks to CMC and Moneybox for that. Opening up the account with the app was a bit tricky and frustrating but got there eventually. Very good interest rate and long may that continue please :)

Smooth transfer in of my Cash ISA account from another provider and great interest rate of 5.7%. Good experience so far.

Transfer was made quickly and efficiently. Kept informed every step of the way. Great rate of interest. What's not to recommend. Excellent service.

Moved my ISA to them attracted by a bonus...

Had to chase up the bonus, they claimed an "adminstration error", they did pay it in the end.

App is poor compared to others, and customer service is hopeless. They ignore emails/secure messages, so you have to phone them. A little odd for an "app" product.

When I wanted a small withdrawal, a few months later. Email confirmation said 3-5 days. I never received the money.

After two lengthy calls to customer services, they told me it was MY FAULT for not chasing it up as there was an internal hold on the payment!
I had no notification of this mysterious hold. They didn't actually need anything from me, so I don't believe them.

First CS promised the payment would be made within a few hours. Turned out to be a lie.
Later, the second CS said it would be another day to process...I get the idea they don't know what they're doing. Not great for an organisation holding your money.

UPDATE: Finally recieved the withdrawal (7 working days) after:
1 secure message (never answered)
3 phone calls
Account is an "easy access" cash ISA.

I'm very happy with my experience of using CMC Invest so far. From transferring an existing cash Isa to them, to making my first deposit. This was all done very quickly compared to other providers I am currently dealing with. Plus their Easy Access Cash Isa currently has a top interest rate at 5.70% The only thing I would like to be added to the account process is that you send an email confirmation to the customer, confirming that a deposit has been received.

All good thank you

Very easy and quick transfer and a great cash ISA rate thank you.

It's very easy to buy shares every thing straight forward

Very good experience in communication and service, transferred ISA very quickly indeed, would recommend

Easy to set, easy to use.

The CMC Invest app is ergonomically laid out, and very intuitive to navigate around, enhancing the overall investment experience. I made the right choice to invest with you.

Easy to open a new cash ISA and was able to arrange for a matured ISA to be transferred in. The whole process took only a few days and I can now monitor my combined ISA funds in one place with a very competitive rate of interest.

Excellent service from day one ISA was opened easily and also made atransfer to my account from another provider within 3 days. Excellent interest rate paid daily. I certainly recommend CMC as a home for an ISA.

Very straight forward to open a new ISA, my initial deposit was showing next working day and then my transfer in was completed within 7 days. Interest accrued daily in the app so nice to see how it builds up and also a very good rate. Great so far

Opened a cash ISA for this year's allowance,easy and straight forward.
With good communication last year's transfer went ahead. Would not hesitate to recommend.

Not great so far. ISA transferred ok. Card payments to Isa been in limbo for a number of days. A bit concerning. Spoken to a couple of agents who were helpful. But get the feeling they are not very well set up. Trust is a big thing with financial products at the moment I do not trust CMC

I had issues in funding the account which delayed my deposit clearing by around two weeks. I did ultimately resolve this with CMC (although this did take longer than expected) and CMC did reimburse the lost interest. Unfortunately we missed out on the 0.85% new account opening bonus by just a few days and CMC would not retrospectively apply this despite the initial problems we encountered. This is why my review is 4 stars and not 5. Goodwill is good business especially when errors are made. CMC were fairly rigid about the account opening bonus not being applied which would have otherwise earned us an extra £175 in interest had we opened the account just 3 or 4 days later. The underlying rate is still market-leading however so we will stick with CMC for now.

Pretty shady. Takes a few days for cash ISA deposits to be "settled" (until then, presumably not counted for interest), almost a week and counting for bank to be verified (until then, cannot withdraw, so funds stuck inside a "flexible" ISA). Stroppy responses when you get them. No reply to messages. Best avoided, unless you like being ghosted.

Update - I received a nice reply 5 days ago to my request to close the account. I am to be contacted about the closure. And then nothing again. They really are hopeless. In the meantime, a withdrawal request for £1 made a week ago is still ongoing ... I wonder if these white hairs is from dealing with these losers, or from the sheer passage of time.

Never bought stocks/shares etc before and found CMC really easy to use would highly recommend

ISA transfer still in progress, rate advertised with 3 months bonus rate but company not prepared to honour this despite the offer being advertised ongoing. Think I dodged a bullet dealing with a disingenuous company.
20k Transfer cancelled app deleted in favour of a provider with common sense.

Email received wanting to know what wrong. Not very agile response to say the least. As explained, applied to transfer 20 k. Transfer was going to take some time due to tax year etc. However, the 3 months bonus you offered 48 hours later on line, considering you were going to take some weeks to transfer from Zopa, you could have honoured the offer. Instead you took ages to reply then said brand new customers only. Account closed transfer aborted. I don't deal with disgenuos folk with no flexibility or solution. Transfer comple with another provider. Shocking wooden response and not a start to any financial relationship.
