Quartz splashback

[johnny2007]

I doubt the problem is with the splashback not being square.
Most likely cupboards and worktop are not parallel as others said.
Easily fixed by adjusting wall units.
BTW, end decor panels must be installed after splashback.
And wall units are usually adjusted higher than final position to allow easy installation of splashback, then lowered with adjusting screws.
Just saying, it's not only the quartz fitters fault, the kitchen fitter should've known that he needed to come back to adjust wall units, notch and fit end panels.

I am annoyed with the kitchen fitter he should have known this. The end panels would have been fine though as they managed to get it tight on the side near the kitchen splashback. However there is another decor panel strip under the cabinets which should have been taken off so that they didn't have to account for it as I believe this is why they gave tolerance to be able to slot the splashback in.
