Brick wall cutting. Tool advise needed All manner of questions and solutions to problems and issues surrounding the subject of brickwork, blockwork and stonework

[the new block]

Hello all,

I need some advise on the right tool to use.
I recently ordered a new PVC window via a friend. To my surprise my mate did order the wrong size (He forget to reduce the size by 10mm). Now I have to cut the exterior brick wall by 10mm to 15mm from one side only. I am just wondering what best tool to use? A grinder, Electric saw, etc ?
I am looking for a clean straight cut rather than a hammer & chisle..

I appreciate some advise..

Thank you in advance,,
