We initially looked elsewhere as we didn't necessarily want the hassle of measuring and ordering the units ourselves. However every single kitchen company we went to sent someone out to measure and they all had different measurements(!) - some were way off! In the end, and mostly because we found a very good fitter, we decided to do it ourselves. The fitter has been great and checked our order and pointed out a few things which helped (e.g. the required gap for units either side of the hood where there is a gas hob). We mocked up some plans using a free online CAD website, marked it up and ordered. No major bumps in the road as yet(!).
If i used them i would be looking to fit it myself. Its things like the units come in say 1000mm or 500mm, what if your space is 1200mm. What fills that gap.
