These are the starting point in the planning and design process and it's essential that there is sufficient illumination to work comfortably and safely. It's particularly important if worktops and splashbacks are made from a dark material, such as black granite, and it also helps to make working areas feel more spacious.
You'll need direct lighting where any kitchen prep is going to take place - worktops, sink and hob - to ensure that all chopping and cooking is done safely, without shadows. Look for recessed or semi-recessed fittings, as exposed light fittings will collect grease and grime more easily. Under-cabinet lighting is one of the best solutions with LEDs offering excellent illumination and energy efficiency. Try to place them at 50cm-60cm intervals for best results.
You could consider illuminating drawers and cabinets to make it easier to find that elusive palette knife. Sensors allow the cabinet or drawer to instantly light up when opened, while string lights in larder units are especially useful.
