Hi,

Sort data (PostCode,Surname,Title) and then run this (TEST (data) first!).
It checks ALL three fields and deletes any duplicate rows.


HTH

Sub DeleteDups()

Dim ws1 As Worksheet
Dim lastrow As Long
Dim r As Long

Set ws1 = Worksheets("Sheet1")
With ws1
lastrow = .Cells(Rows.Count, 1).End(xlUp).Row
For r = lastrow To 2 Step -1
If Application.And(.Cells(r, "A") = .Cells(r - 1, "A"), .Cells(r, "C") =
..Cells(r - 1, "C"), .Cells(r, "J") = .Cells(r - 1, "J")) Then
.Rows(r).Delete shift:=xlUp
End If
Next r
End With

End Sub
