The limited evidence for Offa's direct involvement in the kingdom between 765 and 776 includes two charters of 774 in which he grants land in Kent; but there are doubts about their authenticity, so Offa's intervention in Kent prior to 776 may have been limited to the years 764–65.
Bukti terbatas keterlibatan langsung Offa di dalam kerajaan di antara tahun 765 dan 776 termasuk dua carter pada tahun 774 dimana ia memberikan tanah di Kent; namun ada keraguan mengenai keaslian mereka, sehingga ikut campur Offa di Kent sebelum tahun 776 diduga terbatas pada tahun 764–65.
