Thinking about getting back into kitchen fitting after 25 years out. Thoughts please

I think one of the biggest changes is in Solid Surface Worktop Materials. There are so many available now all with their good and bad points.
I used to fit Corian back in the 90's and now we have so many variations on this type of worktop. Solid 20-30mm options, 44mm Encore (5mm solid surface on a chipboard core).

I could go on but its all down to reading the instructions and making sure the joints are very clean before you bond up. Similarly with appliances, read the fitting instructions and make sure the ventilation and spacing etc are correct.
