Potential GDPR breach - letting agent

I am having an annoying dispute with my LL and their letting agent that I wont bore people with.

In that context I got an email last night which was sent by a family member of the LL to the letting agent and accidentally cc'd me in. Small point but I never gave my consent to the letting agent for my email address (and who knows what else) to be shared with anyone. Only the named LL should have my data I would argue.

Easily done by them I am sure, but I can I leverage this potential breach and give them a scare?

Start with their ts and Cs.

Say you’d like a reduction in your rent or you will take them down to Chinatown

Since the landlord has ultimate legal responsibility I can't imagine there isn't an automatic provision for your data to be shared with them. Maybe the family member is their agent idk.

Yes, the data can of course by shared with the Landlord (my email is on the tenancy agreement I think) but surely not his family unless I say so?

Letting agents are all wideboy bullshitters. Worth threatening action to keep them in line.

Ask the ICO.

No. Hth

Remember that blabbing NatWest woman?

In the grand scheme of data breaches it’s tiny.

SS - I agree it would be a total try on, it has not prejudiced me at all but they are being very petty and this strikes me as being a useful stick to beat them with.

Yes I am sure they will be terrified of some pen pusher banging on about GDPR. "Oh no, I'll be up before the estate agent ethics committee!"

Going only on what you’ve said on here - sounds like you’ve lost perspective, focus on what’s important and have a think about what really is important and disregard ego driven stuff and irrelevant noise
