I answered a similar question on agency repair earlier: https://yallacompare.com/answers/questions/question/agency-repair-for-a-2014-car/?show_answer=650#answer_650
In a nutshell, only oman and union will offer ageny repair for cars over 3 years old
I believe that agency repair is harder to come by when your car is older than 3 years old (though @jonathan may be able to correct me there). But there should still be plenty of options. If you head to https://yallacompare.com/insurance/en/car/ and enter your details, you’ll see which policies come with agency repair on the quotes page.
