Replacing built in oven and hob and amtcing worktop

[Kevin]

I need to replace the built in oven as the grill is not longer working correctly. The oven is standard 600mm wide, the hob is 580mm x 500mm but at the back of the hob is a vent for the oven also the hob has a hinged lid. How can I blank off the gap for the oven vent as I understand modern ovens vent at the front. I was in John Lewis and they said that you can only replace the work top. I was hoping that there would be some sort of standard template to put on top of the work top then cut a new opening. I guess that I can fit an aluminium or stainless steel strip behind the new hob to fill the opening.

The words "amtcing worktop" in the subject of your post are bit mysterious but I think if you could post a photo of what you are trying to deal with it would help people to come up with some suggestions.

What I mean is the cut out in the work top will be bigger than a the new set up. Currently it is hob and vent for the oven plus cut out for the hinges of the lid. Title should read matching.
