Can a letting agents withhold landlords name/details?

[Sarahjsxx]

Hello,
So we've had a very difficult time trying to move into a new rental property, we were due to move tomorrow and yesterday the landlord removed the property from the market! So we are in a very difficult situation
We passed all the referencing checks, but the landlord kept asking for more information, my husband and I have different surnames but we've been married 7 years (not that this should matter) the landlord asked us to prove we are married, for 2 different references from our previous properties which we gave and apparently after that they just removed it from the market, these requests had been going on for the last 2 weeks. Rental properties rarely come up where we live and due to the small timeframe we were desperate for the property
In any case, we asked the letting agency for the landlords name and email or phone number, they said they can't give this due to GDPR, is this true? This does seem unfair due to the landlord knowing absolutely everything about our lives at this point and we can't know this basic detail?

But not all prospective tenants have the right documents (e.g. eVisa/ biometric documentation) for a share code, and in those cases you need to see original documents. If names are different on different documents then they may ask for a marriage certificate to confirm status.

Insurance is another whole matter, but I'm not going to risk invalidating my insurance by accepting someone who is economical with the truth.

All of the Agents I work with will ONLY accept share codes but I tend to work in a certain market where people coming from overseas have work sponsored visas so its never an issue.
