try:

Sub Add4Min()
Dim LRow As Long
Dim rngC As Range
Dim dblSub As Double

With ActiveSheet
LRow = .Cells(Rows.Count, 1).End(xlUp).Row
For Each rngC In .Range("A1:A" & LRow)
dblSub = TimeValue(Left(rngC, 5))
rngC = Format(dblSub + TimeSerial(0, 4, 0), "hh:mm") _
& " " & Mid(rngC, 7, 99)
Next
End With
End Sub
