These [problem]mers are sending out unsolicited emails trying to get you to click on a link that directs to another website to trick you into switching your supplier.
The email claims that you are a subscriber/user of ourproperty.co.uk when the likelihood is that you've never ever heard of them before, and they have simply acquired a mailing list from some where to spam people with.
Please let everyone you know to mark anything from this company as spam and/or phishing attacks.
I recommend that everyone reports them to the ombudsman.
