Worktop Repair help/ideas

Whilst doing a repair to the door from kitchen to shower room, I put my drill on the work surface adjacent to the kitchen sink. Son came into the van and knocked the drill over causing the chuck to nose dive into surface making a 1cm hole in the surface. The work surface is a hollow structure so filling the hole is difficult. Has anyone come across this predicament before and how did you fix it? Replacing the whole worktop section would be a nightmare 
Any help or ideas would be great. 
Thanks Mal

Self adhesive floor tiles from B&Q worked for us, easy to trim using paper template and finish edges with silicon. 3 years since I repaired ours this way and still as good as day we did the repair

Just put 'worktop' into the search box (top right) and you'll find lots of previous threads on the subject with lots of suggestions.

Self adhesive iron on wood veneer could look good.....
