Yes there has been a professional valuation

You may submit your professional valuation to the additional information mailbox at ATEDadditionalinfo.CTIAA@hmrc.gsi.gov.uk

You should head the e-mail “ATED Professional Valuation”.  

If HMRC has provided you with an ATED UTR, you can include this in the body of the e-mail.  If you do not have an ATED UTR please include the postcode of the property that you entered on your return.  This will help HMRC match the additional information to your return.   

Any information you send to us by email is at your own risk.
